RESUMO

Many countries have encountered coronavirus pandemic crisis around the world. Through the outbreak of this disease in Iran, preventive plans have been implemented to break the chain of the disease infection. These measures in the economic sector have affected supply, production and demand, and to some extent have led to the partial or complete closure of some businesses and occupations. In the context, it seems that innovative an "innovation capacity" infrastructure measures and turning to innovation in this crisis can be a strategy to moderate and optimize the situation. This study tries to design concepts of the fisheries firms' innovation capacity model in the context of the COVID-19 pandemic crisis. After collecting data, they were analyzed using SPSS and PLS SMART software, which were performed in two parts: descriptive statistics and analytical or inferential statistics. A novel research model is presented to examine the impact of factors such as innovation management, social, cultural, human and organizational capital, crisis strategies, government actions in crisis situations, and marketing strategies in crisis situations, as well as, recognition and application of marketing advantages in crisis situations, which offers a re-analysis of innovation capacity. According to the results, among the variables played a significant role on the level of innovation capacity in epidemic conditions, innovation management (p> 0.000; ß = 0.593), and recognition and application of marketing advantages (p> 0.049; ß = 0.209) were the most significant, independent variables affecting the innovation capacity, which explained its variations.


Muitos países enfrentaram crises na pandemia de coronavírus em todo o mundo. Por meio do surto dessa doença no Irã, planos preventivos foram implementados para quebrar a cadeia de infecção da doença. Essas medidas no setor econômico afetaram a oferta, a produção e a demanda e, em certa medida, levaram ao fechamento parcial ou total de alguns negócios e serviços. Nesse contexto, parece que medidas de infraestrutura inovadoras e com "capacidade de inovação" podem ser uma estratégia para moderar e otimizar a situação nesta crise. Este estudo tenta desenhar conceitos do modelo de capacidade de inovação das empresas de pesca no contexto da crise da pandemia de COVID-19. Após a coleta dos dados, eles foram analisados ​​por meio dos softwares SPSS e PLS SMART e realizados em duas partes: estatística descritiva e estatística analítica ou inferencial. Um novo modelo de pesquisa é apresentado para examinar o impacto de fatores como gestão da inovação, capital social, cultural, humano e organizacional, estratégias de crise, ações governamentais em situações de crise e estratégias de marketing em situações de crise, bem como reconhecimento e aplicação de vantagens de marketing em situações de crise, que oferece uma reanálise da capacidade de inovação. De acordo com os resultados, entre as variáveis ​​que desempenharam um papel significativo no nível de capacidade de inovação em condições epidêmicas, a gestão da inovação (p > 0,000; ß = 0,593) e o reconhecimento e aplicação de vantagens de marketing (p > 0,049; ß = 0,209) foram as variáveis ​​independentes mais significativas que afetaram a capacidade de inovação, o que explicou suas variações.

RESUMO

The coronavirus disease 2019 (COVID-19) pandemic is an unprecedented worldwide health crisis. Many previous research studies have found and investigated its links with one or some natural or human environmental factors. However, a review on the relationship between COVID-19 incidence and both the natural and human environment is still lacking. This review summarizes the inter-correlation between COVID-19 incidence and environmental factors. Based on keyword searching, we reviewed 100 relevant peer-reviewed articles and other research literature published since January 2020. This review is focused on three main findings. One, we found that individual environmental factors have impacts on COVID-19 incidence, but with spatial heterogeneity and uncertainty. Two, environmental factors exert interactive effects on COVID-19 incidence. In particular, the interactions of natural factors can affect COVID-19 transmission in micro- and macro- ways by impacting SARS-CoV-2 survival, as well as human mobility and behaviors. Three, the impact of COVID-19 incidence on the environment lies in the fact that COVID-19-induced lockdowns caused air quality improvement, wildlife shifts and socio-economic depression. The additional value of this review is that we recommend future research perspectives and adaptation strategies regarding the interactions of the environment and COVID-19. Future research should be extended to cover both the effects of the environment on the COVID-19 pandemic and COVID-19-induced impacts on the environment. Future adaptation strategies should focus on sustainable environmental and public policy responses.

RESUMO

The contagious coronavirus disease-2019 pandemic has led to an increasing number of disposable face masks (DFMs) abandoned in the environment, when they are exposed to the air condition, the broken of chemical bond induced aging is inevitably occurred which meantime would cause a drastic decrease of the mechanical flexibility. However, the understanding of between chemical bond change related to aging and its micromechanical loss is limited due to the lack of refined techniques. Herein, the atomic force microscopy (AFM) technique was firstly used to observe the aging process induced by methine of the polypropylene-based DFMs. By comparing the micromechanical properties loss, the influences of humidity and light density on the DFM aging were systematically studied in the early 72 h, and it revealed that the increasing scissions number of the easiest attacked methine (Ct-H) can gradually decrease the micromechanical properties of the polypropylene (PP)-based DFM. Furthermore, the results are also validated by the in- situ FTIR and XPS analysis. This work discloses that an aging process can be initially estimated with the micromechanical changes observed by AFM, which offers fundamental data to manage this important emerging plastic pollution during COVID-19 pandemic.

RESUMO

Seroprevalence studies can estimate proportions of the population that have been infected or vaccinated, including infections that were not reported because of the lack of symptoms or testing. Based on information from studies in the United States from mid-summer 2020 through the end of 2021, we describe proportions of the population with antibodies to SARS-CoV-2 as functions of age and time. Slices through these surfaces at arbitrary times provide initial and target conditions for simulation modeling. They also provide the information needed to calculate age-specific forces of infection, attack rates, and - together with contact rates - age-specific probabilities of infection on contact between susceptible and infectious people. We modified the familiar Susceptible-Exposed-Infectious-Removed (SEIR) model to include features of the biology of COVID-19 that might affect transmission of SARS-CoV-2 and stratified by age and location. We consulted the primary literature or subject matter experts for contact rates and other parameter values. Using time-varying Oxford COVID-19 Government Response Tracker assessments of US state and DC efforts to mitigate the pandemic and compliance with non-pharmaceutical interventions (NPIs) from a YouGov survey fielded in the US during 2020, we estimate that the efficacy of social-distancing when possible and mask-wearing otherwise at reducing susceptibility or infectiousness was 31% during the fall of 2020. Initialized from seroprevalence among people having commercial laboratory tests for purposes other than SARS-CoV-2 infection assessments on 7 September 2020, our age- and location-stratified SEIR population model reproduces seroprevalence among members of the same population on 25 December 2020 quite well. Introducing vaccination mid-December 2020, first of healthcare and other essential workers, followed by older adults, people who were otherwise immunocompromised, and then progressively younger people, our metapopulation model reproduces seroprevalence among blood donors on 4 April 2021 less well, but we believe that the discrepancy is due to vaccinations being under-reported or blood donors being disproportionately vaccinated, if not both. As experimenting with reliable transmission models is the best way to assess the indirect effects of mitigation measures, we determined the impact of vaccination, conditional on NPIs. Results indicate that, during this period, vaccination substantially reduced infections, hospitalizations and deaths.

RESUMO

One of the key features of any infectious disease is whether infection generates long-lasting immunity or whether repeated reinfection is common. In the former, the long-term dynamics are driven by the birth of susceptible individuals while in the latter the dynamics are governed by the speed of waning immunity. Between these two extremes a range of scenarios is possible. During the early waves of SARS-CoV-2, the underlying paradigm was for long-lasting immunity, but more recent data and in particular the 2022 Omicron waves have shown that reinfection can be relatively common. Here we investigate reported SARS-CoV-2 cases in England, partitioning the data into four main waves, and consider the temporal distribution of first and second reports of infection. We show that a simple low-dimensional statistical model of random (but scaled) reinfection captures much of the observed dynamics, with the value of this scaling, k, providing information of underlying epidemiological patterns. We conclude that there is considerable heterogeneity in risk of reporting reinfection by wave, age-group and location. The high levels of reinfection in the Omicron wave (we estimate that 18% of all Omicron cases had been previously infected, although not necessarily previously reported infection) point to reinfection events dominating future COVID-19 dynamics.

RESUMO

BACKGROUND: Evidence on the relationship between burnout and post-traumatic stress disorder (PTSD) is limited. We aimed to evaluate the association between burnout and PTSD symptoms among medical staff two years after the coronavirus disease 2019 (COVID-19) pandemic in Wuhan, China, and explore the mediating roles of social support and psychological resilience. METHODS: A multicenter survey was conducted online from January to March 2022 among healthcare professionals from six general hospitals. Hierarchical linear regression was used to detect the predictors of PTSD symptoms. Structural equation modeling (SEM) was used to analyze the pathways from burnout to PTSD symptoms. RESULTS: Hierarchical linear regression showed that burnout, social support, and psychological resilience were significant predictors of PTSD symptoms among medical staff. In the SEM, the standardized total effect of burnout on PTSD symptoms was 0.336(bias-corrected 95 % confidence interval [0.303, 0.367], P < 0.001). Social support and psychological resilience partially mediated the relationship between burnout and PTSD symptoms (indirect effects accounted for 22.3 % of the total effect). LIMITATIONS: Owing to the cross-sectional design, only clues to causal explanations can be provided. CONCLUSIONS: Burnout has significant direct and indirect effects on PTSD symptoms. Furthermore, social support and psychological resilience might be effective ways to reduce the impact of burnout on PTSD symptoms in medical staff after a major public health outbreak.

RESUMO

BACKGROUND: The prevalence of depression symptoms among U.S. adults increased dramatically during the early months of the COVID-19 pandemic. We sought to understand the impact of the pandemic on people with a history of depression. METHODS: In June 2020, a national sample of 5023 U.S. adults, including 760 reporting past/current diagnoses of depression, completed survey measures related to the COVID experience, coping, anxiety, depression, and PTSD. RESULTS: After adjusting for sociodemographic characteristics, a history of depression increased the odds of negative effects of pandemic on multiple aspects of life: routines, access to mental health treatment, alcohol use, prescription painkiller use, and other drug use. Those with a history of depression also scored significantly higher on the PHQ-8, GAD-7, and PDS-5 (all ps < 0.0001). Greater use of adaptive coping strategies was significantly associated with lower scores, and greater use of maladaptive strategies with higher scores. Individuals reporting a history of depression reported greater use of both adaptive and maladaptive strategies. CONCLUSIONS: Adaptive coping strategies appear to be protective and help regulate symptomatology, suggesting that particular focus during the clinical encounter on developing tools to promote well-being, alleviate stress, and decrease perceptions of helplessness could mitigate the effects.

RESUMO

The COVID-19 pandemic has underscored the need to understand the dynamics of SARS-CoV-2 respiratory infection and protection provided by the immune response. SARS-CoV-2 infections are characterized by a particularly high viral load, and further by the small number of inhaled virions sufficient to generate a high viral titer in the nasal passage a few days after exposure. SARS-CoV-2 specific antibodies (Ab), induced from vaccines, previous infection, or inhaled monoclonal Ab, have proven effective against SARS-CoV-2 infection. Our goal in this work is to model the protective mechanisms that Ab can provide and to assess the degree of protection from individual and combined mechanisms at different locations in the respiratory tract. Neutralization, in which Ab bind to virion spikes and inhibit them from binding to and infecting target cells, is one widely reported protective mechanism. A second mechanism of Ab protection is muco-trapping, in which Ab crosslink virions to domains on mucin polymers, effectively immobilizing them in the mucus layer. When muco-trapped, the continuous clearance of the mucus barrier by coordinated ciliary propulsion entrains the trapped viral load toward the esophagus to be swallowed. We model and simulate the protection provided by either and both mechanisms at different locations in the respiratory tract, parametrized by the Ab titer and binding-unbinding rates of Ab to viral spikes and mucin domains. Our results illustrate limits in the degree of protection by neutralizing Ab alone, the powerful protection afforded by muco-trapping Ab, and the potential for dual protection by muco-trapping and neutralizing Ab to arrest a SARS-CoV-2 infection.

RESUMO

Susceptible-exposed-infectious-recovered (SEIR) models were applied to assess the effectiveness of non-pharmaceutical interventions (NPIs) and to study the dynamic behavior of the COVID-19 pandemic. Recently, SEIR models have evolved to address the change of human mobility by some NPIs for predicting the new confirmed cases. However, the models have serious limitations when applied to Seoul. Seoul has two representative quarantine policies, i.e. social distancing and the ban on gatherings. Effects of the two policies need to be reflected in different functional forms in the model because changes in human mobility do not fully reflect the ban on gatherings. Thus we propose a modified SEIR model to assess the effectiveness of social distancing, ban on gatherings and vaccination strategies. The application of the modified SEIR model was illustrated by comparing the model output with real data.

RESUMO

The COVID-19 epidemic has lasted for more than two years since the outbreak in late 2019. An urgent and challenging question is how to systematically evaluate epidemic developments in different countries, during different periods, and to determine which measures that could be implemented are key for successful epidemic prevention. In this study, SBD distance-based K-shape clustering and hierarchical clustering methods were used to analyse epidemics in Asian countries. For the hierarchical clustering, epidemic time series were divided into three periods (epidemics induced by the Original/Alpha, Delta and Omicron variants separately). Standard deviations, the Hurst index, mortality rates, peak value of confirmed cases per capita, average growth rates, and the control efficiency of each period were used to characterize the epidemics. In addition, the total numbers of cases in the different countries were analysed by correlation and regression in relation to 15 variables that could have impacts on COVID-19. Finally, some suggestions on prevention and control measures for each category of country are given. We found that the total numbers of cases per million of a population, total deaths per million and mortality rates were highly correlated with the proportion of people aged over 65 years, the prevalence of multiple diseases, and the national GDP. We also found significant associations between case numbers and vaccination rates, health expenditures, and stringency of control measures. Vaccinations have played a positive role in COVID-19, with a gradual decline in mortality rates in later periods, and are still playing protective roles against the Delta and Omicron strains. The stringency of control measures taken by a government is not an indicator of the appropriateness of a country's response to the outbreak, and a higher index does not necessarily mean more effective measures; a combination of factors such as national vaccination rates, the country's economic foundation and the availability of medical equipment is also needed.

RESUMO

In March 2020 mathematics became a key part of the scientific advice to the UK government on the pandemic response to COVID-19. Mathematical and statistical modelling provided critical information on the spread of the virus and the potential impact of different interventions. The unprecedented scale of the challenge led the epidemiological modelling community in the UK to be pushed to its limits. At the same time, mathematical modellers across the country were keen to use their knowledge and skills to support the COVID-19 modelling effort. However, this sudden great interest in epidemiological modelling needed to be coordinated to provide much-needed support, and to limit the burden on epidemiological modellers already very stretched for time. In this paper we describe three initiatives set up in the UK in spring 2020 to coordinate the mathematical sciences research community in supporting mathematical modelling of COVID-19. Each initiative had different primary aims and worked to maximise synergies between the various projects. We reflect on the lessons learnt, highlighting the key roles of pre-existing research collaborations and focal centres of coordination in contributing to the success of these initiatives. We conclude with recommendations about important ways in which the scientific research community could be better prepared for future pandemics. This manuscript was submitted as part of a theme issue on "Modelling COVID-19 and Preparedness for Future Pandemics".

RESUMO

BACKGROUND: This meta-analysis and systematic review aimed to evaluate the global prevalence and risk factors of mental problems (i.e., depression, anxiety, stress, sleep disorder, posttraumatic stress disorder (PTSD), burnout, psychological distress, and suicidal ideation) among medical students during the COVID-19 pandemic. METHOD: We searched PubMed, Embase, Web of Science, psycARTICLES, PsycINFO, CNKI, and Wan Fang for studies on the prevalence of mental problems among medical students from January 1, 2020, to April 1, 2022. The pooled prevalence was calculated by random-effect models. We performed a narrative review to identify the risk factors. RESULTS: The meta-analysis included 201 studies (N = 198,000). The prevalence of depression (41 %, 95 % CI, 37-45 %,), anxiety (38 %,95 % CI, 34 %-42 %), stress (34 %, 95 % CI, 27 %-42 %), sleep disorder (52 %, 95 % CI, 44 %-60 %), psychological distress (58 %, 95 % CI, 51 %-65 %), PTSD (34 %, 95 % CI, 22 %-46 %), suicidal ideation (15 %, 95 % CI, 11 %-18 %) and burnout (38 %, 95 % CI, 25 %-50 %) was high. The major risk factors were being female, being junior or preclinical students, exposure to COVID-19, academic stress, psychiatric or physical disorders history, economic trouble, fear of education impairment, online learning trouble, fear of infection, loneliness, low physical activity, low social support, problematic internet or smartphone use, and young age. LIMITATIONS: Most studies were cross-sectional. Few studies provided a reasonable response rate, suggesting potential selection bias. CONCLUSIONS: The study demonstrated a high prevalence and risk factors for mental problems during COVID-19, calling for mental health services. Our findings are valuable for college and health authorities to identify high-risk students and provide targeted intervention.

RESUMO

The Covid-19 crisis has caused several social-related issues; the sanitary is, perhaps, the most significant one. Lockdowns and vaccination were implemented to fight the Covid-19 virus. From a sustainability perspective, Covid-19 has been considered a meaningful crisis driver that has affected nations' economies and social and natural capitals. The literature presents clues that effects appear to be different among countries. Recognizing its importance as public policies for sustainability, this study aims to assess how the sustainability of countries has changed after Covid-19, focusing on countries' economic power that reflects their capacity to face the crisis. A sample of 89 countries is considered, and 2019-2020 are set as base years for data gathering, which covers the first year of the Covid-19 crisis. Sustainability is conceptually supported and represented by a 3-D cube. The natural environment is expressed by the ecological footprint (EF) method, the economic capital by the gross domestic product (GDP), and the social capital by the happiness index. Results show that sustainability of economies was negatively affected after first year of Covid-19 crisis, but in different magnitudes, according to nations' economic power. While the sustainability of the wealthiest economies was slightly changed during 2019-2020 but maintained within the named 'useful-order' world (environmentally unsustainable, productive, and happy), the poorest economies pushed about 169 million people into the worst performance, reaching the 'ineffective' world (environmentally unsustainable, unproductive, and unhappy). Numbers highlight the inequalities of sustainability performance among countries, according to their capacity to face the Covid-19 crisis. The shield of the richest evaluated countries comprising 5 % of the world population is more powerful than the shield of the poorest evaluated countries carrying 67 % of the world population. Results claims for efforts to make different policies and provide economic support differently for countries, since although we are all under the same storm, but in different boats.

RESUMO

Public health surveillance systems for COVID-19 are multifaceted and include multiple indicators reflective of different aspects of the burden and spread of the disease in a community. With the emergence of wastewater disease surveillance as a powerful tool to track infection dynamics of SARS-CoV-2, there is a need to integrate and validate wastewater information with existing disease surveillance systems and demonstrate how it can be used as a routine surveillance tool. A first step toward integration is showing how it relates to other disease surveillance indicators and outcomes, such as case positivity rates, syndromic surveillance data, and hospital bed use rates. Here, we present an 86-week long surveillance study that covers three major COVID-19 surges. City-wide SARS-CoV-2 RNA viral loads in wastewater were measured across 39 wastewater treatment plants and compared to other disease metrics for the city of Houston, TX. We show that wastewater levels are strongly correlated with positivity rate, syndromic surveillance rates of COVID-19 visits, and COVID-19-related general bed use rates at hospitals. We show that the relative timing of wastewater relative to each indicator shifted across the pandemic, likely due to a multitude of factors including testing availability, health-seeking behavior, and changes in viral variants. Next, we show that individual WWTPs led city-wide changes in SARS-CoV-2 viral loads, indicating a distributed monitoring system could be used to enhance the early-warning capability of a wastewater monitoring system. Finally, we describe how the results were used in real-time to inform public health response and resource allocation.

RESUMO

BACKGROUND: An increasing number of research has documented the positive associations between psychological inflexibility (PI) and mental health problems (i.e., depressive, anxiety, and stress symptoms) during the COVID-19 pandemic. However, the documented associations have been inconsistent. This review thus aimed to quantitatively summarize primary research to gain better estimates of these associations. METHODS: A systematic literature review was conducted in six databases and three-level meta-analytic models were used to statistically synthesize effect sizes and to examine moderators of the associations between PI and depressive, anxiety, and stress symptoms. RESULTS: A total of 22 studies yielded 63 effect sizes on associations between PI and depressive, anxiety, or stress symptoms. The results of three separate meta-analyses revealed a large and significant association between PI and depressive (r = 0.580, 95 % CI [0.549; 0.775]), anxiety (r = 0.548, 95 % CI [0.468; 0.761]), and stress symptoms (r = 0.548, 95 % CI [0.506; 0.725]). The association between PI and depressive symptoms is stronger for males than for females, and the association between PI and stress symptoms varies by type of measure that primary studies use to assess PI and stress symptoms. LIMITATIONS: Temporal or causal conclusions are not allowed due to cross-sectional nature of the associations included in meta-analyses. Clinical samples with high levels of stress were underrepresented. CONCLUSIONS: PI seems an important risk factor for symptoms of depression, anxiety, and stress, and should therefore be targeted in interventions addressing mental health problems during the COVID-19 pandemic and beyond.

RESUMO

BACKGROUND: The first goal of this study was to assess longitudinal changes in burnout among psychotherapists prior to (T1) and during the COVID-19 pandemic (T2). The second objective was to assess the effects of job demands, job resources (including organizational support for evidence-based psychotherapies, or EBPs) and pandemic-related stress (T2 only) on burnout. METHOD: Psychotherapists providing EBPs for posttraumatic stress disorder in U.S. Department of Veterans Affairs (VA) facilities completed surveys assessing burnout, job resources, and job demands prior to (T1; n = 346) and during (T2; n = 193) the COVID-19 pandemic. RESULTS: Burnout prevalence increased from 40 % at T1 to 56 % at T2 (p < .001). At T1, stronger implementation climate and implementation leadership (p < .001) and provision of only cognitive processing therapy (rather than use of prolonged exposure therapy or both treatments; p < .05) reduced burnout risk. Risk factors for burnout at T2 included T1 burnout, pandemic-related stress, less control over when and how to deliver EBPs, being female, and being a psychologist rather than social worker (p < .02). Implementation leadership did not reduce risk of burnout at T2. LIMITATIONS: This study involved staff not directly involved in treating COVID-19, in a healthcare system poised to transition to telehealth delivery. CONCLUSION: Organizational support for using EBPs reduced burnout risk prior to but not during the pandemic. Pandemic related stress rather than increased work demands contributed to elevated burnout during the pandemic. A comprehensive approach to reducing burnout must address the effects of both work demands and personal stressors.

RESUMO

BACKGROUND: To study the longitudinal impact of co-occurring mental health problems, and to identify vulnerable groups in need of mental health support during the COVID-19 pandemic. METHODS: Analyses were based on data from 681 French participants in the international COVID-19 Mental Health Study, collected at four times (05/2020-04/2021). Symptoms of depression, anxiety and post-traumatic stress disorder (PTSD) were assessed using the Patient Health Questionnaire 9, the Generalized Anxiety Disorder-7 and the PTSD Check List for DSM-5. We performed k-means for longitudinal data to build trajectories of adults' depression, anxiety and PTSD symptoms and identify subgroups psychologically vulnerable. We then assessed whether mental health trajectories were predicted by lockdown regulations. RESULTS: A high and a low cluster of mental health scores were identified. In both groups, mental health scores varied significantly across time. Levels of all mental health scores were lowest when COVID-19-related restrictions were lifted and highest when restrictions were in place, except for PTSD. No scores returned to the previous level or the initial level of mental health (p < 0.05). Participants with high levels of symptoms were characterized by younger age (OR: 0.98, 95 % CI: 0.97-0.99), prior history of mental disorders (OR: 3.46, 95 % CI: 2.07-5.82), experience of domestic violence (OR: 10.54, 95 % CI: 1.54-20.68) and medical issues (OR: 2.16, 95 % CI: 1.14-4.03). LIMITATIONS: Pre-pandemic data were not available and the sample was recruited mainly by snowball sampling. CONCLUSION: This study revealed subtle differences in the evolution of symptom trajectories during the first year of the Covid-19 pandemic, and highlighted several characteristics associated with the two clusters.

RESUMO

BACKGROUND: With the pandemic of COVID, the public are faced with tremendous threatens both physically and mentally. Postpartum depression (PPD) is one of the most serious complications of childbearing, bringing severe impact on a woman's mental state and mood after birth. Research has shown that maternal mental state is closely correlated with PPD, those undergo the emergency or significant life changes during the postpartum period are more likely to suffer from PPD. In this study, we conducted the meta-analysis to estimate the association between PPD and COVID-19 pandemic. METHODS: PubMed, Web of Science, PsycINFO, ScienceDirect, CNKI, China Science and Technology Journal Database, and WANFANG Database were searched for potentially relevant articles published before April 2022. Review Manager 5.2 was used to perform a meta-analysis and subgroup analysis to compute the pooled odds ratio. RESULTS: A total of 26 studies were included in this review. The overall pooled prevalence of PPD in the review was 24 % (95 % CI: 0.19-0.29), with China's at 22 % (95 % CI 0.16-0.28) and other countries at 25 % (95 % CI 0.18-0.32) during the COVID-19 pandemic. Moreover, compared to those who did not experience COVID-19, those who experienced it had an increased risk of PPD[OR:1.83(95 % CI 1.70-1.97)]. CONCLUSIONS: According to this analysis, there was a significantly higher prevalence and odds of PPD in those who suffered from the COVID-19 pandemic. Additionally, we also found that China had a lower prevalence of postpartum depression than other countries during the COVID-19 pandemic. Our study may provide the instruction for the care of new mother under the situation of COVID-19 prevalence.
