Abstract: (862 Views)
Background and Objectives: COVID-19 pandemic caused a lot of severe problems in the world. This study investigated the epidemiology of the disease in Tehran in the first quarter of the epidemic's beginning.
Methods: The available information recorded for patients from 20 February 2020 to 20 May 2020 in Tehran was used. To prepare disease-related distribution maps, the addresses of patients' residences in Google Earth were called to ARC-GIS version 10-4. The methods used in GIS include IDW, Hotspot and also software development.
Results: Overall, 3699 individuals whose PCR results were positive in Tehran were included in the study. Out of the total number of them, 550 people died and the fatality rate of the disease in hospitalized patients was 14.9%. One thousand five hundred thirty patients (41.4%) have recovered, and the remaining 1619 patients were under treatment until data collection. Of the total, 1479 confirmed cases were women (40%). The average age was 57.4 years (SD=16.5). The density of cases in areas 4, 8 and 13, and the existence of some cluster diseases in neighborhoods such as Tehran Pars, Ayat and Pirouzi streets are noteworthy points.
Conclusion: The trend of the COVID-19 epidemic is dire and requires long-term measures. Nevertheless, to control this disease, the health system, the policy of isolating patients and suspicious people, wear masks especially in densely populated areas, are the most important controlling factors.
