A comprehensive perspective on potentially hazardous elements (PHEs) bound with particulate matters in ambient air of landfill sites: a systematic review and probabilistic risk assessment.

Air pollution from Potentially Hazardous Elements bound with particulate matter (PHEs bound PM) in landfill air is a significant concern for human health. To date, no comprehensive research has focused on the health risks of PHEs bound to PM in landfill air. This systematic review aimed to examine PHEs, including Lead (Pb), Cadmium (Cd), Chromium (Cr), Arsenic (As), Nickel (Ni), and Zinc (Zn) bound with PM in landfill air and assess the health risk for workers and waste management personnel. The systematically search was made in different electronic databases. After the screening, 18 most relevant studied focused on PHEs bound PM in landfill air were selected. The data extraction analysis indicated that mean concentrations of Pb, Cd, Cr, As, Ni, and Zn in landfill air were 0.3037, 0.0941, 0.4093, 0.0221, 0.2768, and 0.7622 µg/m3, respectively. Except for Pb, the concentrations of other PHEs bound to PM exceeded USEPA air quality standards. In addition, Non-carcinogenic risks from Cd, Cr, and Ni exposure exceeded permissible limits (HQ > 1), while As had an HQ value of 0.401. Carcinogenic risks from As, Cd, Ni, and Pb exposure were 1.31 × 10-5, 5.10 × 10-4, 3.51 × 10-5, and 2.03 × 10-6, respectively. Notably, the lifetime carcinogenic risk for workers exposed to Cr in polluted air (6.17 × 10-3) exceeded permissible limits (10-4 to 10-6). In conclusion, given the high carcinogenic and non-carcinogenic risks of some PHEs bound PM in landfills, it is necessary to conduct more research on the health effects of interaction with these PHEs bound PM on communities and the environment in different countries. Also, it is necessary to evaluate the role of different landfill operational activities on atmospheric dispersion of PHEs bound PM) in landfill air.

High resolution melting curve analysis for rapid detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants.

Since the emergence of the original Wuhan SARS-CoV-2 strain, several new variants of the virus have emerged. Alpha, Beta, Gamma, Delta and the most recent Omicron variants have been introduced during this pandemic. Several methods including, but not restricted to, allele-specific PCR, ligation with rolling circle amplification and real-time PCR with allele-specific probes are able to detect mutations as low as a single nucleotide polymorphism. High-resolution melting curve analysis is ano-ther technique to assess any mutations in a nucleic acid chain. Confirmed samples with SARS-CoV-2 infection were subjected to variant identification using a de novo-designed HRM assay. In order to select for mutations with the highest effect on Tm of the amplicon, deletion mutations of NSP6 (Del 3675-3677), and S1 (Del 144) were chosen for HRM analysis. HRM analysis for the amplicon of the primer set-1 (NSP6) resulted in Tm differences of -0.39°C, +0.4°C, and -0.6°C between Alpha, Delta, and Omicron variants, respectively, in comparison to the original Wuhan strain. Moreover, HRM analysis of the amplification performed by primer set-2 (S1) led to Tm differences of +0.32°C, -0.26°C, and +0.24°C between Alpha, Delta, and Omicron variants, respectively, in comparison to original Wuhan strain. The test was able to specify each sample to its variant group with more than 90 percent of confidence. The results obtained in this study demonstrate that using a single closed-tube strategy with a HRM-equipped machine, screening new variants of the virus is possible in a fast and reliable way. Keywords: high resolution melting; SARS coronavirus 2; mutation; variant; genotyping.

The Association of Acute Watery Diarrhea in Iranian Pilgrims of Iraq with Cholera Cases in Iranians.

Background: Despite the advances in the control of infectious diseases like cholera, they can potentially cause epidemics, especially in mass gathering events. One of the most important countries on the walking way of the Arbaeen religious event is Iran, which requires health system preparedness. The aim of this study was to predict the cholera epidemic in Iran by using the syndromic surveillance system of Iranian pilgrims in Iraq. Methods: The data of the Iranian pilgrims with acute watery diarrhea in Iraq during the Arbaeen religious event and the confirmed cholera cases of pilgrims after returning to Iran were analyzed. We used the Poisson regression model of the relationship between the numbers of cases to evaluate acute watery diarrhea and cholera. Spatial statistics and hot spot analysis were used to identify the provinces with the highest incidence. SPSS software Version 24 was used for statistical analysis. Results: The frequency of acute watery diarrhea cases was 2232 and the frequency of cholera in pilgrims after returning to Iran was 641. The results of spatial analysis for acute watery diarrhea cases showed a high number of acute watery diarrhea cases in the Khuzestan and Isfahan provinces, located in hot spots. Using Poisson regression, the relationship between the number of acute watery diarrhea reported in the syndromic surveillance system and the number of cholera cases was confirmed. Conclusion: The syndromic surveillance system is useful to predict the outbreak of infectious diseases in large religious mass gatherings.

Adverse effects following COVID-19 vaccination in Iran.

BACKGROUND: Vaccination is a key intervention to prevent COVID-19. Many vaccines are administered globally, yet there is not much evidence regarding their safety and adverse effects. Iran also faces this challenge, especially as data regarding the Sputnik V vaccine is sparse. Therefore, the aim of this study is to determine the adverse effects of the most commonly used vaccines in Iran. METHODS: Using a retrospective cohort study design, 6600 subjects aged 18 years or older who had received two doses of any of the three COVID-19 vaccines (Sinopharm, AstraZeneca, and Sputnik V) were selected using a random sampling method between March and August 2021. Subjects were asked about any adverse effects of the vaccines by trained interviewers via telephone interview. Vaccine-related adverse effects in individuals during the first 72 h and subsequently following both doses of the vaccines were determined. The demographic variables, type of administered vaccine, adverse effects, and history of the previous infection with COVID-19 were collected. Descriptive statistics (mean, standard deviation) and analytical statistics (Chi-squared and Wilcoxon tests) were performed at a 95% significance level using STATA software version 15 (STATA Corp, College Station, TX, USA). RESULTS: From 6600 participants, 4775 responded (response rate = 72.3%). Of the participants, 1460 (30.6%) received the AstraZeneca vaccine, 1564 (32.8%) received the Sinopharm vaccine and 1751 (36.7%) received the Sputnik V vaccine. 2653 participants (55.56%) reported adverse effects after the first dose and 1704 (35.7%) after the second dose. Sputnik V caused the most adverse effects with 1449 (82.7%) vaccine recipients reporting symptoms after the first or second dose, compared with 1030 (70.5%) for AstraZeneca and only 585 (37.4%) for the Sinopharm vaccine. The most common adverse effects after the first dose were fatigue (28.37%), chill/fever (26.86%), and skeletal pain (22.38%). These three adverse effects were the same for the second dose, although their prevalence was lower. CONCLUSIONS: In this study, we demonstrate that the Sputnik V vaccine has the highest rate of adverse effects, followed by the AstraZeneca and Sinopharm vaccines. COVID-19 vaccines used in Iran are safe and there were no reports of serious adverse effects.

Involvement of Pseudomonas aeruginosa in the occurrence of community and hospital acquired diarrhea, and its virulence diversity among the stool and the environmental samples.

Transmission of Pseudomonas aeruginosa along the food chain could cause gastrointestinal infections. To show this involvement, the prevalence, putative virulence genotype, and antibiotic resistance phenotype of P. aeruginosa isolates from stool of 1482 patients with community and hospital acquired diarrhea were compared with 87 isolates from the environmental samples. The results showed infection with P. aeruginosa in 3.4% of the cases, while 57.4% of vegetable samples were contaminated. Significantly higher frequency of lasB (98%), aprA (98%), exoY (98%), and exoS (90%), but lower rate of exoT (39.2%), was detected among the stool isolates. Multi-drug resistance (MDR) phenotype was detected in 25.5% and 4% of the stool and vegetable isolates, respectively. A higher rate of studied virulence genes was detected among the MDR strains vs non-MDR strains. These results indicate P. aeruginosa as a causative agent of diarrhea either among the hospitalized patients and those with community-acquired diarrhea.

Risk Communication in Early Containment of COVID-19 Pandemic in Iran: Implementation of the World Health Organization Strategic Preparedness and Response Plan (WHO-SPRP).

Background: Health systems must have functional and efficient preparedness and response plans to manage pandemics. Moreover, it is essential to adjust to changing circumstances and the dynamic character of pandemics. The World Health Organization (WHO) introduced the Strategic Preparedness and Response Plan (SPRP), emphasizing 144 measures across 10 pillars, helping governments prepare and respond to the coronavirus disease 2019 (COVID-19) pandemic. This study aimed to determine how the Iranian health system, based on the WHO-SPRP, addresses strategic preparedness and response plan in the COVID-19 pandemic at the national level. Methods: The WHO-SPRP was adopted and translated into Persian by 2 bilingual natives. The chief of the health office requested that authorized officers complete the SPRP. Then, a meeting was held by officers of related units involved in COVID-19 management to address the SPRP at regional and national levels. Results: Our findings suggest that up to August 2020, effective risk communication and community engagement were not fully established. Our response plan lacked evidence-based information and educational messaging to consistently shape public opinion and impression of a respiratory pandemic. Conclusion: The Iranian health care system and services were almost able to address the SPRP and perform the major indicators that the WHO had proposed. However, special attention should be paid to risk communication and community engagement to empower informed decision-making by individuals and communities.

Epidemiologic characteristics of orthopedic surgical site infections and under-reporting estimation of registries using capture-recapture analysis.

BACKGROUND: Surgical Site Infections (SSIs) are among the leading causes of the postoperative complications. This study aimed at investigating the epidemiologic characteristics of orthopedic SSIs and estimating the under-reporting of registries using the capture-recapture method. METHODS: This study, which was a registry-based, cross-sectional one, was conducted in six educational hospitals in Tehran during a one-year period, from March, 2017 to March, 2018. The data were collected from two hospital registries (National Nosocomial Infection Surveillance System (NNIS) and Health Information Management database (HIM)). First, all orthopedic SSIs registered in these sources were used to perform capture-recapture (N = 503). Second, 202 samples were randomly selected to assess patients` characteristics. RESULTS: Totally, 76.24% of SSIs were detected post-discharge. Staphylococcus aureus (11.38%) was the most frequently detected bacterium in orthopedic SSIs. The median time between the detection of a SSI and the discharge was 17 days. The results of a study done on 503 SSIs showed that the coverage of NNIS and HIM was 59.95 and 65.17%, respectively. After capture-recapture estimation, it was found that about 221 of orthopedic SSIs were not detected by two sources among six hospitals and the real number of SSIs were estimated to be 623 ± 36.58 (95% CI, 552-695) and under-reporting percentage was 63.32%. CONCLUSION: To recognize the trends of SSIs mortality and morbidity in national level, it is significant to have access to a registry with minimum underestimated data. Therefore, according to the weak coverage of NNIS and HIM among Iranian hospitals, a plan for promoting the national Infection Prevention and Control (IPC) programs and providing updated protocols is recommended.

The national rate of intensive care units-acquired infections, one-year retrospective study in Iran.

BACKGROUND: Hospital-acquired infections (HAIs) in intensive care units (ICUs) are among the avoidable morbidity and mortality causes. This study aimed at investigating the rate of ICU-acquired infections (ICU-AIs) in Iran. METHODS: For the purpose of this multi-center study, the rate of ICU-AIs calculated based on the data collected through Iranian nosocomial infections surveillance system and hospital information system. The data expanded based on 12 months of the year (13,632 records in terms of "hospital-ward-month"), and then, the last observation carried forward method was used to replace the missing data. RESULTS: The mean (standard deviation) age of 52,276 patients with HAIs in the ICUs was 47.37 (30.78) years. The overall rate of ICU-AIs was 96.61 per 1000 patients and 16.82 per 1000 patient-days in Iran's hospitals. The three main HAIs in the general ICUs were ventilator-associated events (VAE), urinary tract infection (UTI), and pneumonia events & lower respiratory tract infection (PNEU & LRI) infections. The three main HAIs in the internal and surgical ICUs were VAE, UTI, and bloodstream infections/surgical site infections (BSI/SSI). The most prevalent HAIs were BSI, PNEU & LRI and eye, ear, nose, throat, or mouth (EENT) infections in the neonatal ICU and PNEU & LRI, VAE, and BSI in the PICU. Device, catheter, and ventilator-associated infections accounted for 60.96, 18.56, and 39.83% of ICU-AIs, respectively. The ventilator-associated infection rate was 26.29 per 1000 ventilator-days. Based on the Pabon Lasso model, the lowest rates of ICU-AIs (66.95 per 1000 patients and 15.19 patient-days) observed in zone III, the efficient area. CONCLUSIONS: HAIs are common in the internal ICU wards. In fact, VAE and ventilator-related infections are more prevalent in Iran. HAIs in the ICUs leads to an increased risk of ICU-related mortality. Therefore, to reduce ICU-AIs, the specific and trained personnel must be responsible for the use of the devices (catheter use and ventilators), avoid over use of catheterization when possible, and remove catheters earlier.

Survival rate in patients with ICU-acquired infections and its related factors in Iran's hospitals.

BACKGROUND: Hospital-acquired infections (HAIs) are a well-known cause of morbidity and mortality in hospitalized patients. This study aimed at investigating the survival rate in patients with ICU-acquired infections (ICU-AIs) and its related factors in Iran's hospitals. METHODS: Data were obtained from the Iranian Nosocomial Infections Surveillance (INIS), which registers all necessary information on the main types of infection from different units of each included hospital. One thousand one hundred thirty-four duplicate cases were removed from the analysis using the variables of name, father's name, age, hospital code, infection code, and bedridden date. From 2016 to 2019, 32,998 patients diagnosed with ICU-AI from about 547 hospitals. All patients were followed up to February 29, 2020. RESULTS: The median age of patients with ICU-AIs was 61 (IQR = 46) years. 45.5, 20.69, 17.63, 12.08, and 4.09% of infections were observed in general, surgical, internal, neonatal and pediatric ICUs, respectively. Acinetobacter (16.52%), E.coli (12.01%), and Klebsiella (9.93%) were the major types of microorganisms. From total, 40.76% of infected patients (13,449 patients) died. The 1, 3, 6-months and overall survival rate was 70, 25.72, 8.21 1.48% in ICU-AI patients, respectively. The overall survival rate was 5.12, 1.34, 0.0, 51.65, and 31.08% for surgical, general, internal, neonatal and pediatric ICU, respectively. Hazard ratio shows a significant relationship between age, hospitalization-infection length, infection type, and microorganism and risk of death in patients with ICU-AI. CONCLUSIONS: Based on the results, it seems that the nosocomial infections surveillance system should be more intelligent. This intelligence should act differently based on related factors such as the age of patients, hospitalization-infection length, infection type, microorganism and type of ward. In other words, this system should be able to dynamically provide the necessary and timely warnings based on the factors affecting the survival rate of infection due to the identification, intervention and measures to prevent the spread of HAIs based on a risk severity system.

Interdisciplinary cooperation, through modern scientific methods, could help to handle the consequences of the pandemic and to avoid the recurrence of future pandemics.

A systematic review and meta-analysis on the prevalence of Escherichia coli and extended-spectrum ß-lactamase-producing Escherichia coli in pregnant women.

PROPOSE: The aim of the present study was to determine the prevalence of E. coli and extended-spectrum ß-lactamase-producing (ESBL) E. coli in pregnant women in a systematic review and meta-analysis study. METHODS: We searched important databases, including Medline (PubMed), Embase, Scopus, Web of sciences, Cochrane library, Ovid, and CINHAL to retrieve all articles reporting the prevalence of ESBL E. coli in pregnant women that published from January 1990 to June 2020. RESULTS: The pooled prevalence of E. coli in pregnant women with and without symptoms of UTI after combining 82 studies with a sample size of 33,118 was 29% (29%; %95 CI 23, 36%). The prevalence based on urine, Feacal, and vagina samples was 26% (% 95 CI 19-34%), 77% (% 95 CI 22-98%), and 32% (% 95 CI 17-48%), respectively. Also, 19 studies with a sample size of 9,200 reported ESBL E. coli prevalence in pregnant women. After combining the results of these studies, the pooled prevalence of ESBL E. coli in pregnant women was 34% (34%; %95 CI 24, 43%). The pooled prevalence of E. coli in pregnant women with HIV was 9%(9%; %95 CI 7, 11%). CONCLUSION: According to the results of this study, the prevalence of E. coli and ESBL E. coli is high in pregnant women. Also, the overuse of antibiotics was higher in European and Asian pregnant women than other continents.

Evaluation of Reinfection in COVID-19 Patients in the World: A Narrative Review.

Background: The evaluation of reinfection and the genetic structure of all human and virus genomes could help to develop programs and protocols for providing services and ultimately to prevent the disease by producing more effective vaccines. Therefore, the aim of this study was to investigate the presence and occurrence of COVID-19 reinfection through a narrative review study. Methods: We searched the Medline (PubMed), Embase, Scopus, Web of Science, Cochrane library, Ovid, and CINHAL databases. Inclusion criteria included all studies whose main purpose was to provide information about the occurrence or presence of reinfection in patients with COVID-19. An independent samples t test was used to compare the continuous outcomes between the 2 groups. Results: The mean duration of the first episode in the group with mild or moderate COVID-19 was 24.42±1.67 days, and it was 21.80±3.79 days in the group with severe COVID-19. The mean duration of the second episode (reinfection) in patients with mild or moderate form was 15.38 ± 5.57 days, and it was 19.20±2.98 days in patients with severe form. In both episodes, the duration of the disease did not significantly differ between the 2 groups (p=0.484 in the first episode; p=0.675 in the second episode), but the interval to the occurrence of reinfection in patients with the mild or moderate form was significantly longer than those with the severe form (p<0.001). In this instance, the time interval in patients with the mild or moderate form was 36.63±5.71 days while in those with the severe form of the disease it was 29.70±5.65 days. Besides, the genomes of the viruses isolated from the first and second episode were different. Conclusion: According to the results, all patients should be very careful about the severity of the second episode because of the more need for medical interventions for saving the patients. The interval between the first end and the second episode as well as the duration of each episode is highly important for better management of the disease.

Health Effects of Overweight and Obesity in 195 Countries over 25 Years.

BACKGROUND: Although the rising pandemic of obesity has received major attention in many countries, the effects of this attention on trends and the disease burden of obesity remain uncertain. METHODS: We analyzed data from 68.5 million persons to assess the trends in the prevalence of overweight and obesity among children and adults between 1980 and 2015. Using the Global Burden of Disease study data and methods, we also quantified the burden of disease related to high body-mass index (BMI), according to age, sex, cause, and BMI in 195 countries between 1990 and 2015. RESULTS: In 2015, a total of 107.7 million children and 603.7 million adults were obese. Since 1980, the prevalence of obesity has doubled in more than 70 countries and has continuously increased in most other countries. Although the prevalence of obesity among children has been lower than that among adults, the rate of increase in childhood obesity in many countries has been greater than the rate of increase in adult obesity. High BMI accounted for 4.0 million deaths globally, nearly 40% of which occurred in persons who were not obese. More than two thirds of deaths related to high BMI were due to cardiovascular disease. The disease burden related to high BMI has increased since 1990; however, the rate of this increase has been attenuated owing to decreases in underlying rates of death from cardiovascular disease. CONCLUSIONS: The rapid increase in the prevalence and disease burden of elevated BMI highlights the need for continued focus on surveillance of BMI and identification, implementation, and evaluation of evidence-based interventions to address this problem.

Control of antimicrobial resistance in Iran: the role of international factors.

BACKGROUND: Antimicrobial resistance (AMR) is currently causing various challenges for all countries around the world. Accordingly, the WHO is placing a great emphasis on the global partnership and allinaces to drive countries towards developing policy guidances and a strategic framework for AMR contatiment. This study thus seeks to elaborate on the international factors underlying AMR management in Iran. METHODS: Semi-structured interviews were conducted with managers from the Ministry of health (n = 14), Iran veterinary organization (n = 4), the national professional associations (n = 3) and researchers (n = 3), between November 2018 and July 2019. Participants were selected using purposeful and snowball sampling. Interviews were recorded and transcribed verbatim and were subsequently coded and analyzed thematically using MAXQDA software (V.18) and reported. RESULTS: International enabling and predisposing factors were identified in relation to the AMR control in the country. Enabling factors included knowledge transfer, facilitation in policy agenda setting, formulation and implementaion process, and AMR monitoring. Predisposing factors, alternatively, encompassed the migration of infectious patients, trafficking of medicine and livestock from neighboring countries, and the imposed sanctions. CONCLUSION: Nowadays, AMR is taken cognizance of as a global challenge, thus to be addressed effectively, needs an international consensus more than ever. This harmony would not certainly underrate national efforts, but instead, is needed to reinforce such efforts through e.g. technical and financial assistance. It is suggested for policymakers to use all available political and legal means such as health diplomacy to establish humanitarian channels in order to enhance global convention and remove possible barriers as the sanctions and reduce their adverse consequences for AMR control.

Estimation of the net reproductive number of COVID-19 in Iran.

Background: Estimating the net reproductive number of COVID-19 virus can reveal the rate and severity of the disease transmission in the Iranian society to health researchers and practitioners. Also, it signifies the importance of the disease to the community. Thus, the aim of this study was to determine the net reproductive number of COVID-19 in Iran and its different provinces. Methods: This study was conducted on the data of COVID-19 patients in Iran from February 21 to March 8, 2020. To determine the net reproductive number of COVID-19 in Iran, the serial interval and ß value were first determined using linear regression analysis. Then, the net reproductive number values were calculated for Iran and its different provinces. Results: The results of this study showed that the net reproductive number of COVID-19 in Iran was 1.31. Using the available data up to March 15, 2020, the highest net reproductive number was in Mazandaran, Yazd, Isfahan, Qazvin, and Zanjan provinces, with values of 2.07, 1.86, 1.84, and 1.76, respectively. The net reproductive number also showed an increasing trend in Kohgiluyeh and BoyerAhmad province. Conclusion: It seems that although the net reproductive number of the virus had a decreasing trend in the provinces, it is still high. Therefore, sanitary measures in these provinces should be pursued more seriously. On the other hand, social distancing is a topic that should be taken into consideration, that is, social gatherings and contacts should be avoided as much as possible and strategies and facilities for this action should be developed by the government and health policymakers.

Investigating the factors affecting the survival rate in patients with COVID-19: A retrospective cohort study.

Background: As hospitalized patients with COVID-19, especially those who are admitted to ICU or die afterwards, generally have comorbidities, the aim of this study was to determine the factors affecting the survival rate of COVID-19 patients in Iran using a retrospective cohort. Methods: This retrospective cohort study was conducted on patients with COVID-19 who referred to medical centers under the supervision of Iran University of Medical Sciences, Tehran, Iran, from February 22 to March 25, 2020. The final date of follow-up was April 19, 2020. All consecutive inpatients with laboratory-confirmed COVID-19 were included in this study. Clinical laboratory, radiological, treatment, and demographic data were collected and analyzed. The associations among gender, immune disease, diabetes, liver disease, cardiovascular disease, kidney disease, chronic pulmonary disease, cancer, chronic nervous disease, type of treatment, and risk of death were analyzed. The Kaplan-Meier and Log-rank tests were used to estimate survival rate and compare survival rates, respectively. Results: The total number of deaths or desired event in the study was 329 (10.3%).The risk of death in the age groups of 50-60 years, 60-70 years, and >70 years compared to the 30-40 age group was 2.17 (95% CI: 1.03, 4.55; p: 0.040); 3.72 (95 % CI: 1.80, 7.68; p: 0.001) and 5.09 (95 % CI: 2.49, 10.40; p: 0.001), respectively. The results showed men had 11.5% more risk of deaths than women (HR: 1.11; 95 % CI: 0.89, 1.39; p: 0.341). Kidney disease increased the risk of death by 52.3% in these patients, which was not statistically significant (HR: 1.78; 95 % CI: 1.04, 3.04; p: 0.035). Also, chronic pulmonary diseases and diabetes increased the risk of death in COVID-19 patients by 89.5% and 41.3% compared to COVID-19 patients without chronic pulmonary diseases and diabetes [(HR: 1.89; 95 % CI: 1.17, 3.04; p: 0.008), (HR: 1.41; 95 % CI: 1.01, 1.96; p: 0.038)]. Conclusion: Based on the results of this study, more attention and care should be paid to COVID-19 patients with underlying diseases, such as chronic obstructive pulmonary disease, diabetes, and kidney disease to reduce the number of deaths.

Comparative performance of hybrid model based on discrete wavelet transform and ARIMA models in prediction incidence of COVID-19.

Objective: Public health surveillance is an important aspect of outbreak early warning based on prediction models. The present study compares a hybrid model based on discrete wavelet transform (DWT) and ARIMA (Autoregressive Integrated Moving Average) for predicting incidence cases due to COVID-19. Methods: In the current cross-sectional stuady based on time-series data, the incidence data for confirmed daily cases of COVID-19 from February 26, 2019, to April 25, 2022, were used. A hybrid model based on DWT and ARIMA and a pure ARIMA model were used to predict the trend. All analyzes were performed by MATLAB 2018, stata 2015, and Excel 2013 computer software. Results: Compared to the ARIMA model, the prediction results of the hybrid model were closer to the actual number of incident cases. The correlation between predicted values by the hybrid model with real data was higher than the correlation between predicted values by the ARIMA model with actual data. Conclusions: Discreet Wavelet decomposition of the dataset was combined with an ARIMA model and showed better performance in predicting the future trend.
