ABSTRACT
Background: Serological studies can demonstrate pathogen circulation in regional populations and reflect public health mea-sures' effectiveness during different pandemic phases. By late November 2021, coinciding with the third pandemic wave, the sero-prevalence of SARS-CoV-2 spike IgG antibodies among the Iranian population was 32.63%. Objective(s): This study aimed to assess the Iranian population's seroprevalence during the fifth pandemic wave by analyzing donated blood samples. Method(s): This population-based cross-sectional study was conducted on Iranian blood donors referred to all 31 main provincial capitals between August 2021 and September 2021. The participants selected through quota sampling were asked to complete a questionnaire on socio-demographics and coronavirus disease 2019 (COVID-19)-related information. Also, SARS-CoV-2 spike IgG antibodies were measured in serum samples using SARS-CoV-2 enzyme-linked immunosorbent assay (ELISA) kits. The seroprevalence was weighted based on the gender and age groups of the population and then adjusted for test performance. Result(s): Totally 3,339 blood donors participated in this study. The overall population-weighted seroprevalence adjusted for test performance was 52.67% (95% confidence interval (CI): 50.14-55.21). Seroprevalence was higher among participants with a high school diploma (55.45%, 95% CI 50.61-60.29), a positive history of close contact with COVID-19 patients (65.23%, 95% CI 60.83-69.63), and previous positive COVID-19 PCR tests (86.51%, 95% CI 82.32-90.7). Conclusion(s): More than half of the study population was exposed to SARS-CoV-2, indicating a 1.7-fold increase in the seroprevalence between late November 2020 and mid-September 2021. Our finding illuminated the pattern of Iran's fifth wave of the pandemic.Copyright © 2023, Author(s).
ABSTRACT
Data and information technology is a key component in responding to covid-19 disease and is an effective way for informing personnel, resource management, and inter-intra organizational communication. During the pandemic, technology-based tools enable organizations to facilitate the widespread information dissemination, real-time tracking, meetings and daily activities virtualization and telemedicine visits for patients, physicians, and other health care providers as a major risk group of COVID-19. © 2022, Iranian Medical Informatics Association (IrMIA).

ABSTRACT
Coronavirus disease 2019 (COVID-19) has seriously spread worldwide. One of the problems of COVID-19 patients is co-infection with other microbial infections such as fungal infections that are severely life-threatening. Mucormycosis, one of these opportunistic fungal diseases that is mistakenly known as black fungal disease, has been reported in Iran and the world. This non-systematic review is intended to review the latest studies in the world and Iran about the incidence of mucormycosis in COVID-19 patients to better understand the disease and its predisposing factors. In general, patients with COVID-19 with underlying diseases, diabetic patients, those treated with immunosuppressive drugs, ICU patients, and patients under invasive mechanical ventilation are at higher risk for mucormycosis. Therefore, early diagnosis, treatment, and prevention methods can be effective in reducing the risk of mucormycosis in COVID-19 patients.
