RESUMO
OBJECTIVE: This study aims to compare the differences in COVID-19 prevention and control policies adopted by the United Kingdom (UK) during the first wave (31 January 2020 to 6 September 2020) and the second wave (7 September 2020 to 12 April 2021), and analyze the effectiveness of the policies, so as to provide empirical experience for the prevention and control of COVID-19. Methods We systematically summarized the pandemic prevention and control policies of the UK from official websites and government documents, collated the epidemiological data from 31 January 2020 to 12 April 2021, and analyzed the effectiveness of the two waves of pandemic prevention and control policies. RESULTS: The main pandemic prevention and control policies adopted by the UK include surveillance and testing measures, border control measures, community and social measures, blockade measures, health care measures, COVID-19 vaccination measure, and relaxed pandemic prevention measures. The new cases per day curve showed only one peak in the first wave and two peaks in the second wave. The number of new cases per million in the second wave was much higher than that in the first wave, and the curve fluctuated less. The difference between mortality per million was small, and the curve fluctuated widely. CONCLUSION: During the first and second waves of COVID-19, the UK implemented three lockdowns and managed to slow the spread of the pandemic. The UK's experience in mitigating the second wave proves that advancing COVID-19 vaccination needs to be accompanied by ongoing implementation of non-pharmacological interventions to reduce the transmission rate of infection. And a stricter lockdown ensures that the containment effect is maximized during the lockdown period. In addition, these three lockdowns featured distinct mitigation strategies and the UK's response to COVID-19 is mitigation strategy that reduce new cases in the short term, but with the risk of the pandemic rebound.

BACKGROUND: This study aimed to compare the prevention and control strategies adopted by the United States and India in the COVID-19 outbreak and analyze the effectiveness of their strategies, in order to provide empirical experience for the prevention and control of the epidemic. METHODS: This study extracted official data on COVID-19 from various official websites, summarized the policies in place in the United States and India, and evaluated the effectiveness of their policies. RESULTS: The United States has adopted a series of mitigation strategies to control the two waves of epidemic, including strengthening virus detection, calling on the people to wear masks and so on. As of May 30, 2021, although the daily new cases there decreased to some extent, the effect was not ideal. The US's daily new cases ranked fourth and the cumulative number of confirmed cases ranked first in the world. India has adopted containment strategies in the initial stage of the outbreak, making the epidemic relatively stable. In the later stage, India has turned to adopt mitigation strategies. In addition, many factors including the lack of medical resources and premature relaxation measures led to the rapid deterioration of the epidemic situation. As of May 30, 2021, although the daily new cases in India has a downward trend, it ranked first in the world, and the cumulative number of confirmed cases ranked second. CONCLUSION: There are differences between the epidemic prevention strategies adopted by the United States and India, especially India's containment strategies which helped it better control the epidemic in the early stage. However, the epidemic in the two countries is still severe. With the advent of virus mutants and the absence of immune barriers, it is meaningful that the two countries continue to take non-pharmacotherapy intervention measures and accelerate vaccination, according to specific national conditions adopt containment strategies that can control the epidemic more quickly when necessary, and pay attention to the risk of epidemic rebound caused by premature relaxation of epidemic prevention policies.

OBJECTIVE: To provide experience for formulating prevention and control policies, this study analyzed the effectiveness of the Coronavirus disease 2019(COVID-19) prevention and control policies, and evaluated health equity and epidemic cooperation among BRICS countries. METHODS: This study summarized the pandemic prevention and control policies in BRICS countries and evaluated the effectiveness of those policies by extracting COVID-19 related data from official websites. RESULT: As of May 4, 2021, responding to COVID-19. China adopted containment strategies. China's total confirmed cases (102,560) were stable, without a second pandemic peak, and the total deaths per million (3.37) were much lower than others. India and South Africa who adopted intermediate strategies have similar pandemic curves, total confirmed cases in India (20,664,979) surpassed South Africa (1,586,148) as the highest in five countries, but total deaths per million (163.90) lower than South Africa (919.11). Brazil and Russia adopted mitigation strategies. Total confirmed cases in Brazil (14,856,888) and Russia (4,784,497) continued to increase, and Brazil's total deaths per million (1,936.34) is higher than Russia (751.50) and other countries. CONCLUSION: This study shows BRICS countries implemented different epidemic interventions. Containment strategy is more effective than intermediate strategy and mitigation strategy in limiting the spread of COVID-19. Especially when a strict containment strategy is implemented in an early stage, but premature relaxation of restrictions may lead to rebounding. It is a good choice to combat COVID-19 by improving the inclusiveness of intervention policies, deepening BRICS epidemic cooperation, and increasing health equities.

OBJECTIVE: Our research summarized policy disparities in response to the first wave of COVID-19 between China and Germany. We look forward to providing policy experience for other countries still in severe epidemics. METHODS: We analyzed data provided by National Health Commission of the People's Republic of China and Johns Hopkins University Coronavirus Resource Center for the period 10 January 2020 to 25 May 252,020. We used generalized linear model to evaluate the associations between the main control policies and the number of confirmed cases and the policy disparities in response to the first wave of COVID-19 between China and Germany. RESULTS: The generalized linear models show that the following factors influence the cumulative number of confirmed cases in China: the Joint Prevention and Control Mechanism; locking down the worst-hit areas; the highest level response to public health emergencies; the expansion of medical insurance coverage to suspected patients; makeshift hospitals; residential closed management; counterpart assistance. The following factors influence the cumulative number of confirmed cases in Germany: the Novel Coronavirus Crisis Command; large gathering cancelled; real-time COVID-19 risk assessment; the medical emergency plan; schools closure; restrictions on the import of overseas epidemics; the no-contact protocol. CONCLUSIONS: There are two differences between China and Germany in non-pharmaceutical interventions: China adopted the blocking strategy, and Germany adopted the first mitigation and then blocking strategy; China's goal is to eliminate the virus, and Germany's goal is to protect high-risk groups to reduce losses. At the same time, the policies implemented by the two countries have similarities: strict blockade is a key measure to control the source of infection, and improving medical response capabilities is an important way to reduce mortality.

OBJECTIVE: The study analyzed the common points and discrepancies of COVID-19 control measures of the two countries in order to provide appropriate coping experiences for countries all over the world. METHOD: This study examined the associations between the epidemic prevention and control policies adopted in the first 70 days after the outbreak and the number of confirmed cases in China and Singapore using the generalized linear model. Policy comparisons and disparities between the two countries were also discussed. RESULTS: The regression models show that factors influencing the cumulative number of confirmed cases in China: Locking down epicenter; activating Level One public health emergency response in all localities; the central government set up a leading group; classified management of "four categories of personnel"; launching makeshift hospitals; digital management for a matrix of urban communities; counterpart assistance. The following four factors were the key influencing factors of the cumulative confirmed cases in Singapore: The National Centre for Infectious Diseases screening center opens; border control measures; surveillance measures; Public Health Preparedness Clinics launched. CONCLUSIONS: Through analyzing the key epidemic prevention and control policies of the two countries, we found that the following factors are critical to combat COVID-19: active case detection, early detection of patients, timely isolation, and treatment, and increasing of medical capabilities. Countries should choose appropriate response strategies with health equity in mind to ultimately control effectively the spread of COVID-19 worldwide.

OBJECTIVE: In order to provide experiences for international epidemic control, this study systematically summarized the Coronavirus disease 2019 (COVID-19) prevention and control policies in Japan, Italy, China and Singapore, and also analyzed the possible inequalities that exist in these response approaches to improve global infectious disease control. METHODS: We summarized the epidemic prevention and control policies in Japan, Italy, China, and Singapore, and analyzed the policy effects of these four countries by using the data published by Johns Hopkins Coronavirus Resource Center. RESULTS: As of May 27, 2020, the growing trend of new cases in Japan, Italy, China and Singapore has stabilized. However, the cumulative number of confirmed cases (231139) and case-fatality rate (14.3%) in Italy far exceeded those in the other three countries, and the effect of epidemic control was inferior. Singapore began to experience a domestic resurgence after April 5, with a cumulative number of confirmed cases reaching 32,876, but the case-fatality rate remained extremely low (0.1%). The growth of cumulative confirmed cases in China (84547) was almost stagnant, and the case-fatality rate was low (5.5%). The growth of cumulative confirmed cases in Japan (16661) increased slowly, and the case-fatality rate (4.8%) was slightly lower than that in China. CONCLUSION: This study divided the epidemic prevention and control policies of the four countries into two categories: the blocking measures adopted by China and Singapore, and the mitigation measures adopted by Japan and Italy. According to the Epidemic control results of these four countries, we can conclude that the blocking measures were generally effective. As the core strategy of blocking measures, admitting mild patients into hospital and cases tracing helped curb the spread of the outbreak in Singapore and China. Countries should choose appropriate response strategies on the premise of considering their own situation, increase investment in health resources to ensure global health equity, and eventually control the spread of infectious diseases in the world effectively.

BACKGROUND: The study aimed to analyze the effectiveness of COVID-19 strategies adopted by China, Japan, Singapore, and South Korea. METHODS: We extracted publicly available data from various official websites, summarized the strategies implemented in these four countries, and assessed the effectiveness of the prevention and control measures adopted by these countries. RESULTS: As of October 28, 2020, the growth of daily new confirmed cases has stabilized in China, Singapore, and South Korea. In Japan, the daily new confirmed cases increased sharply since it lifted a state of emergency, but case-fatality maintains at a lower level. The growth of total cases is near stagnant in China and Singapore, with a case-fatality of 5.39 and 0.05% respectively. The case-fatality rate between Japan and South Korea is identical at 1.76%, however, Japan's growth rate of cases has increased more rapidly than South Korea. CONCLUSION: This study found that China, Japan, Singapore, and South Korea accessed the situation within their own borders and implemented different intervention strategies to curb the spread of COVID-19 and maintain lower rates of case-fatality. China, Singapore, and South Korea adopted the containment strategy, while Japan adopted the mitigation strategy. Although Japan's case-fatality maintained at a low level, daily new cases increased faster than the other three countries. This result indicated that a mitigation strategy could be inferior to a containment strategy.

Objective: The aim of this study was to analyze the effectiveness of prevention and control strategies and put forward further measures according to the epidemiological characteristics of Omicron. It summarized the national response during the Omicron epidemic in four countries: China, Israel, South Africa, and the United States. Methods: This study summarized prevention and control measures in China, Israel, South Africa, and the United States in their response to the Omicron epidemic, and it also evaluated the effectiveness of these measures. Results: After the Omicron variant emerged, China and Israel adopted containment strategies, using the "dynamic zero" policy and country closure measures. Meanwhile, South Africa and the United States adopted mitigation strategies, which virtually abandoned social interventions and only focused on medical measures and vaccines. From the first day of reported Omicron cases to 28 February 2022, the four countries reported the following cases: China reported 9,670 new confirmed cases and no deaths, with total deaths per million of 3.21; Israel reported 2,293,415 new confirmed cases and 2,016 deaths, with total deaths per million of 1,097.21; South Africa reported 731,384 new confirmed cases and 9,509 deaths, with total deaths per million reaching 1,655.708; the United States reported 3,042,743 new confirmed cases and 1,688,851 deaths, with total deaths per million reaching 2,855.052, which was much higher than the other countries. Conclusion: Based on this study, it seems that China and Israel adopted containment strategies, while South Africa and the United States adopted mitigation strategies. A rapid response is a powerful weapon against the Omicron epidemic. Vaccines alone will not get any country out of this crisis, and non-pharmacological measures should be used in addition to them. According to the SPO model, future work should consider the strengthening of emergency management capacity, adhering to public health measures, promoting vaccination, and strengthening patient care and close contact management, which are effective measures in coping with Omicron.

PURPOSE: This study compared the government policies and non-pharmaceutical interventions adopted by South Korea, Japan, India, and China in response to COVID-19 during 2020-2021 and assessed their effectiveness. We hope that our research will help control the COVID-19 waves and a future crisis of this nature. METHODS: COVID-19 case data were obtained from Our World in Data database. Combined with case data, we made a retrospective study by analyzing the government policies and non-pharmaceutical interventions taken during this pandemic in these four representative Asian countries (South Korea, Japan, India, and China). RESULTS: From January 2020 to May 18, 2021, South Korea and Japan experienced three waves of COVID-19 outbreaks, but the number of daily new confirmed cases per million people was relatively small in both countries, and South Korea had fewer daily new confirmed cases per million than Japan. Following the COVID-19 outbreak in Wuhan in late 2019, China successfully contained the first wave of the outbreak and was not currently experiencing a large-scale resurgence of the epidemic (Until May 18, 2021). India is experiencing a grim second wave of the epidemic, with far more daily new confirmed cases per million people than South Korea and Japan. CONCLUSION: Successful practices in China and South Korea show that case identification and management, coupled with close contact tracing and isolation, is a powerful strategy. The lessons of Japan and India show that social distancing is an effective measure, but only if it is rigor and persistent. Finally, in both developed and developing countries, the development of health care systems and coordinated government leadership play a key role in overcoming epidemics.
RESUMO
(1) Purpose: This study aimed to analyze coronavirus disease 2019 (COVID-19) vaccine policies and their effectiveness in Italy, India, and South Africa to provide empirical experience for vaccination and COVID-19 pandemic control. (2) Methods: The study systematically summarized the COVID-19 vaccine policies in Italy, India, and South Africa through public information available on the official websites of the World Health Organization and the ministries of health in these three countries. Total vaccinations, COVID-19 vaccination rates, rates of fully vaccinated, rates of booster-vaccinated, and total confirmed cases were selected for cross-sectional comparison of COVID-19 vaccination in these three countries. Daily cases per million, daily deaths per million, and the effective reproduction rate were calculated to measure the effectiveness of COVID-19 vaccine policies implementation in each of these three countries. (3) Results: Italy, India, and South Africa differ in the start date of COVID-19 vaccination, vaccine types, vaccine appointments, and whether vaccinations are free. The COVID-19 vaccination rates in these three countries varied widely, with Italy having the highest and South Africa the lowest. COVID-19 vaccination has had a positive effect on reducing daily deaths and stabilizing the effective reproduction rate. The three countries had experienced more than one outbreak spike due to the spread of new mutated strains since the start of COVID-19 vaccination. (4) Conclusions: This study concluded that responding to the COVID-19 pandemic requires active promotion of basic and booster vaccinations to comprehensively build up the population immune barrier. Promoting equitable distribution of COVID-19 vaccine internationally and solidarity and cooperation among countries maximizes global common interests. By combining vaccination with non-pharmaceutical interventions, the pandemic can be prevented and controlled comprehensively and systematically in three aspects: detection of the source of infection, reduction of transmission routes, and protection of susceptible populations.
RESUMO
OBJECTIVE: This study analyzes the effectiveness of COVID-19 prevention and control in China and Brazil from the perspectives of policy and meteorological conditions, and provides experience for epidemic prevention and control. METHODS: This study collects data on meteorological conditions, vaccination and mutant strains in the two countries to analyze the reasons for the differences in epidemic status between the two countries and extracts public data on COVID-19 through various official websites, summarizes the prevention and control policies implemented by the two countries, and evaluates their effectiveness. RESULTS: As of August 12, 2021, the total number of COVID-19 cases and the daily number of new COVID-19 cases in China have been growing steadily, showing remarkable results in epidemic control. The total number of confirmed cases and the daily number of new confirmed cases in Brazil have continued to increase rapidly. The total death case in Brazil has reached 560,000, far exceeding that in China, and the effect of epidemic prevention and control is not satisfactory. CONCLUSIONS: Multiple factors, such as meteorological conditions, policies and strategies, and economic conditions, can influence the spread of COVID-19, and therefore, the situation varies greatly from country to country. China and Brazil have chosen different interventions in the fight against COVID-19. The policy measures taken by China are typical containment measures and Brazil has a mitigation strategy. From the perspective of the current situation of the epidemic development in both countries, the cumulative death rate and daily new confirmed cases in Brazil are much higher than those in China, which indicates that the containment strategy is more effective than mitigation strategy in preventing and controlling COVID-19. Fighting the epidemic is a global long-lasting battle, and the two countries should learn from each other with the premise of respecting their national conditions. Countries should deepen cooperation and not let up prematurely.

Background: COVID-19 has not been effectively controlled, seriously threatening people's health and socioeconomic development. This study aims to summarise the successful experiences and lessons in containment strategy learned from Asian Low- and Middle-Income Countries (LMICs) during the COVID-19 pandemic and analyse the effectiveness of their measures to provide lessons for LMICs in general. Methods: This is a retrospective study on the effectiveness of China, India, and Vietnam's containment strategies. The objective was to assess the effectiveness of measures taken for COVID-19 and provide lessons for wider LMICs in controlling and preventing the COVID-19 pandemic. Results: As of June 16, 2021, the Indian epidemic was in the declining part of the rebound stage, with a total of 21 521.900 cases per million and 276.740 deaths per million - both the highest among the three countries. Entering the normalised prevention and control stage, China stably remained at a total of 63. 615 cases per million and 3.211 deaths per million. Vietnam's number of new cases per million was very low in the first stage and almost stagnant except for cluster epidemics. In May 2021, the number of new cases per million started to rapidly increase, but the total of deaths per million was at the low level of 0.627. Conclusions: A high attention to epidemics at early stages, strict border control measures, and synchronization of government and population on COVID-19 prevention and control opinions and behaviours play important roles in designing containment strategies. In addition, rapid close contact tracing and large-scale nucleic testing are good options for response to cluster epidemics.

OBJECTIVES: This study analyzed the effects of COVID-19 non-pharmaceutical measures between China and South Korea to share experiences with other countries in the struggle against SARS-CoV-2. METHODS: We used the generalized linear model to examine the associations between non-pharmaceutical measures adopted by China and South Korea and the number of confirmed cases. Policy disparities were also discussed between these two countries. RESULTS: The results show that the following factors influence the number of confirmed cases in China: lockdown of Wuhan city (LWC); establishment of a Leading Group by the Central Government; raising the public health emergency response to the highest level in all localities; classifying management of "four categories of personnel"; makeshift hospitals in operation (MHIO); pairing assistance (PA); launching massive community screening (LMCS). In South Korea, these following factors were the key influencing factors of the cumulative confirmed cases: raising the public alert level to orange (three out of four levels); raising the public alert to the highest level; launching drive-through screening centers (LDSC); screening all members of Shincheonji religious group; launching Community Treatment Center (LCTC); distributing public face masks nationwide and quarantining all travelers from overseas countries for 14 days. CONCLUSION: Based on the analysis of the generalized linear model, we found that a series of non-pharmaceutical measures were associated with contain of the COVID-19 outbreak in China and South Korea. The following measures were crucial for both of them to fight against the COVID-19 epidemic: a strong national response system, expanding diagnostic tests, establishing makeshift hospitals, and quarantine or lockdown affected areas.

BACKGROUND: This study is aimed at confirming the effectiveness of nonpharmaceutical interventions during the COVID-19 outbreak in Hubei, China. METHODS: The data are all from the epidemic information released by the National Health Commission of the People's Republic of China and the Health Commission of Hubei Province. We used the multivariable linear regression by the SPSS 19.0 software: the cumulative number of confirmed cases, the cumulative number of cured cases, and the number of daily severe cases were taken as dependent variables, and the six policies, including the Joint Prevention and Control Mechanism of the State Council, lockdown Wuhan city, the first-level response to public health emergencies, the expansion of medical insurance coverage to suspected patients, mobile cabin hospitals, and counterpart assistance in Hubei province, were gradually entered into multiple linear regression models as independent variables. RESULTS: The factors influencing the cumulative number of diagnosed cases ranged from large to small: mobile cabin hospitals and the expansion of medical insurance coverage to suspected patients. The factors influencing the cumulative number of cured cases ranged from large to small: counterpart support medical teams in Hubei province and mobile cabin hospitals. The factors influencing the number of daily severe cases ranged from large to small: mobile cabin hospitals and the expansion of medical insurance coverage to suspected patients. CONCLUSION: The mobile cabin hospital is a major reason for the successfully defeating COVID-19 in China. As COVID-19 pandemic spreads globally, the mobile cabin hospital is a successful experience in formulating policies to defeat COVID-19 for other countries in the outbreak phase.

OBJECTIVE: This study aimed to analyze the distribution characteristics and influencing factors for the interval between entering mainland China and the diagnosis of imported COVID-19 cases in Guangdong province, in order to provide valuable experience for global pandemic in prevention and control. METHODS: We collected publicly reported data between March 1 and June 2, 2020. Univariate and multivariate regression analyses were performed to identify the significant associated factors with the interval between entering mainland China and diagnosis of imported COVID-19 cases. RESULTS: As of June 2, 2020, a total of 200 imported cases were reported in Guangdong province. The average interval time was 4.25 days with a median of 2 days, the interval time of 68% cases was between 1 and 3 days. The multivariate model results show that the three following factors were critical influencing factors: nationality was foreign nationality (P = 0.037), results of initial nucleic acid detection were negative (P = 0.000) and the interval between entering mainland China and the detection of positive results (T) exceeded two days (P = 0.008). CONCLUSION: The results suggested that all travelers and returning resident should be taken strict sampling and testing, and isolation measures, improved the accuracy of the initial nucleic acid test results, and the detection efficiency and shortening the interval between entering mainland China and detection of positive results.
RESUMO
ABSTRACT: To provide references for global pandemic prevention and control, this study aimed to analyze the epidemiological characteristics and clinical manifestations of 103 new confirmed cases between June 12 and June 15, 2020, in Beijing. All confirmed cases in this study were tested with a positive SARS-CoV-2 reverse transcriptase-polymerase chain reaction and extracting data from the Beijing Municipal Health Commission (June 11 to July 6, 2020). We selected the 103 typical confirmed cases (excluding imported cases) between June 12 and June 15 for statistical analysis and explored differences among different clinical cases. A cluster of COVID-19 was reported in Beijing between June 12 and June 15, 2020, involving 103 confirmed cases. Patients aged 21 to 65âyears old and the mean age was 42.38â±â11.507, the male-to-female sex ratio was 1.40:1. All confirmed cases had a direct or indirect exposure history in the Beijing Xinfadi Market (BXM), and the clinical manifestations of 97% confirmed cases was diagnosed as mild or moderate. Different clinical classification in age (Pâ=â.041), exposure history (Pâ=â.025), fever (Pâ=â.020), and cough (Pâ=â.000) were the statistically significant difference, but there was no statistically significant difference in gender (Pâ=â.501), the type of diagnosis (Pâ=â.478), expectoration (Pâ=â.979), fatigue (Pâ=â.906), dizziness or headache (Pâ=â.848), muscle pain (Pâ=â.825), sore throat or throat discomfort (Pâ=â.852), chills (Pâ=â.933), diarrhea (Pâ=â.431) and runny nose or nasal congestion (Pâ=â.898). This study shows that Beijing's epidemic scope was mainly concentrated in the Xinfadi Market. The initial cases were epidemiologically related to the BXM, the clinical classification of most cases was mild and moderate, and the differences in age, exposure history, fever, and cough among different clinical cases were statistically significant.

In order to describe the Chinese experience for the purposes of global epidemic control, the study analyzed the impact on the COVID-19 pandemic of policies adopted during the lockdown of Wuhan city. Descriptive analysis and stepwise regression analysis were performed using the official case data from January 10, 2020 to April 8, 2020. The results show that the prevention and control policies of Lockdown Wuhan City (LWC) has played a significant role in reducing new case numbers, improving COVID-19's cure rate and reducing mortality. Among the policies of LWC, stay at home, centralized isolation of convalescent patients, launching makeshift hospitals, and centralized isolation of "the four types of personnel" that play a decisive role. As the COVID-19 pandemic progresses, this study provides valuable experience for other countries.

OBJECTIVE: This study aimed to make a comparative analysis of the public health containment measures between China and India, explore the causes of the serious COVID-19 epidemic in India, and eventually to improve global infectious disease control. METHODS: We extracted publicly available data from official websites, summarized the containment measures implemented in China and India, and assessed their effectiveness. RESULTS: China has responded to the COVID-19 outbreak with strict public health containment measures, including lockdown of Wuhan city, active case tracing, and large-scale testing, ultimately preventing a large increase in daily new cases and maintaining a low mortality rate per million population (as of May 5, 2021, daily new cases were 11 and mortality rate per million population was 3.37). India, although imposing a national lockdown to control the pandemic, has not implemented strict testing, tracking, and quarantine measures due to the overburdened healthcare system. Combined with massive lockdown, it has accelerated human mobility and exacerbated the epidemic, resulting in a rapid increase in daily new cases and a high mortality rate per million population (as of May 5, 2021, daily new cases were 412,431 and mortality rate per million population was 166.79). CONCLUSION: China and India implemented public health containment measures to contain the spread of the COVID-19 pandemic based on their national situations. Meanwhile, daily new cases and mortality of COVID-19 also were affected by environmental and socioeconomic. Countries make a comprehensive strategy not only in terms of the biological, pharmaceutical, health, and sanitation sectors but also based on sustainability science and environmental science.
RESUMO
Objective: This study aimed to examine the effectiveness of containment strategies and mitigation strategies to provide a reference for controlling the ongoing global spread of the pandemic. Methods: We extracted publicly available data from various official websites between January 1 and December 31, 2020, summarized the strategies implemented in China, South Korea, Singapore, the United States, the United Kingdom, and France, and assessed the effectiveness of the prevention and control measures adopted by these countries with the daily new cases and mortality rate per 100,000 population. Results: China, South Korea, and Singapore adopted containment strategies, which maintained a proactive approach by identifying and managing cases, tracking and isolating close contacts. China and Singapore had a similar epidemic curve and the new daily cases. As of December 31, 2020, the new daily cases of China and Singapore were below 100 with the mortality rates per 100,000 population of 0.3 and 0.5, respectively. But the new daily case of South Korea was as high as 1,029, with a mortality rate per 100,000 population of 1.8. In contrast, the United States, the United Kingdom, and France responded with mitigation strategies that focus on treating severe cases and those with underlying conditions. They had similar epidemic curves and mortality rates per 100,000 population. The United States had up to 234,133 new confirmed cases per day, and the mortality rate per 100,000 population was 107, while the United Kingdom had 56,029 new confirmed cases per day and the mortality rate per 100,000 population was 108, and France had 20,042 new cases per day, with a mortality rate per 100,000 population of 99. Conclusions: China, Korea, and Singapore, which implemented strict containment measures, had significant outbreak control. Meanwhile, the successful practices in China, Singapore, and South Korea show that the containment strategies were practices that work especially at the individual level identifying and managing the infected patients and their close contacts. In the United States, the United Kingdom, and France, which implemented the mitigation policies, the effect of epidemic prevention and control was not significant that the epidemic continued or even increased epidemic relatively quickly.

ABSTRACT: This study aimed to systematically analyze the effect of Wuhan mobile cabin hospitals (WMCHs) on the novel coronavirus-caused pneumonia (COVID-19) prevention and control in China. Between February 5, 2020 and March 10, 2020, a total of 16 mobile cabin hospitals were constructed in 3 batches to offer over 13,000 beds and admitted more than 12,000 patients in Wuhan City. The strategy of implementing WMCHs in 3 batches played a key role in fighting against COVID-19 in China. (1) The first batch of WMCHs increased hospital admission capacity of COVID-19 patients in Wuhan, which showed initial effect on COVID-19 epidemic control. (2) The operation of the second batch of WMCHs greatly contributed to the rapid growth in discharged patients. (3) After launching the third batch of WMCHs, the COVID-19 epidemic situation in Wuhan improved considerably. The last batch of WMCHs made a substantial contribution to defeating the COVID-19 epidemic in Wuhan.
