en Signs and symptoms across different age groups in COVID-19 patients ویروس شناسی ویروس شناسی پژوهشی اصیل Original Article Background and Objective: In humans, viruses cause respiratory infections that are usually mild, including the common cold, or sometimes it can be fatal. The outbreak of coronavirus disease 2019 (COVID-19) occurred in Wuhan, China was more expansive than initially estimated, with cases now confirmed in several countries. Therefore, it is crucial to determine the clinical symptoms of COVID-19 in different age groups. Methods: This cross-sectional study evaluated the presence of SARS-CoV-2 infection in 219 throat and nasal swab samples using Real-time PCR. All samples were collected from people with respiratory symptoms who went to the grand bazaar. Findings: Of 219 patients examined, 19 (8.6%) positive cases out of 219 for SARS-CoV-2 were found by using Real-time PCR. Among these 19 positive cases of SARS-CoV-2, 6 (2.7%) were under 5, 3 (1.3%) were between 5-18, 4 (1.8%) were between 18-50 and 6 (2.7%) were over 50 years old respectively. Most common symptoms in positive group was cough (89%) and despite other age groups, in patients over 50 years old, myalgia and diarrhea was common. Conclusion: It seems that SARS-CoV-2 symptoms can vary in different age groups but unlike other age groups, in elderly, uncommon symptoms like eyes redness, myalgia and diarrhea seems is seen following COVID-19 infection Respiratory Infection, Diarrhea, Myalgia, COVID-19, SARS-CoV-2 50 57 http://crms.mubabol.ac.ir/browse.php?a_code=A-10-160-1&slc_lang=en&sid=1 Nooshin Eyvazzadeh nooshineyvazzadeh2021@gmail.com 10031947532846002044 10031947532846002044 No Medical Microbiology Research Center ,Qazvin University of Medical Science, Qazvin, Iran A Letafati arashletafati@yahoo.com 10031947532846002045 10031947532846002045 Yes Department of Virology, School of Public Health, Tehran University of Medical Sciences, Tehran, Iran A Gharehkhani amirhosein.gharehkhani@yahoo.com 10031947532846002046 10031947532846002046 No Department of Medical Laboratory Science, Faculty of Para Medicine, Islamic Azad University, Tehran Medical Branch, Tehran, Iran E Khodadoust Soufiani elnazkhodadust@gmail.com 10031947532846002047 10031947532846002047 No Department of Medical Laboratory Science, Faculty of Para Medicine, Islamic Azad University, Tehran Medical Branch, Tehran, Iran Z Zargari qzzlzrg@gmail.com 10031947532846002048 10031947532846002048 No Department of Microbiology, Faculty of Basic Sciences, Karaj Branch Islamic Azad University, Karaj, Iran F Zargari ghzargariii@gmail.com 10031947532846002049 10031947532846002049 No Department of Cellular and Molecular Biology, Faculty of Modern Science, Islamic Azad University, Tehran Medical Branch, Tehran, Iran N Hezarpisheh nurinhp2218@gmail.com 10031947532846002050 10031947532846002050 No Department of Genetics, Faculty of Advanced Sciences and Technology, Islamic Azad University, Tehran Medical Sciences Branch, Tehran, Iran T Beheshti beheshti.toranj@gmail.com 10031947532846002051 10031947532846002051 No Department of Genetics, Faculty of Advanced Sciences and Technology, Islamic Azad University, Tehran Medical Sciences Branch, Tehran, Iran E Andalib elaheandalib8@gmail.com 10031947532846002052 10031947532846002052 No Department of Microbiology, Faculty of Basic Sciences, Islamic Azad University Science and Research Branch, Tehran, Iran N Farajvand niloofar.farajvand13@gmail.com 10031947532846002053 10031947532846002053 No Department of Biological Sciences and Technologies, Faculty of Basic Sciences, Islamic Azad University, Yadegar-e-Imam Khomeini Branch, Tehran, Iran M Pourghasemi pourghamina@gmail.com 10031947532846002054 10031947532846002054 No Department of Biology, Faculty of Basic Sciences, Islamic Azad University, Kazerun, Iran Z Bagherian z72.bagherian@gmail.com 10031947532846002055 10031947532846002055 No Department of Biology, Faculty of Science, Payam-e-Noor University, Takab, Iran Sh Abdizadeh shahrzadabdizadeh@gmail.com 10031947532846002056 10031947532846002056 No Department of Microbiology, Faculty of Modern Sciences, Islamic Azad University, Tehran Medical Sciences Branch, Tehran, Iran M Ahmadinousaabad behaz.ah2020@gmail.com 10031947532846002057 10031947532846002057 No Department of Genetic engineering, Faculty of Genetics, Islamic Azad University, Qaemshahr Branch, Mazandaran, Iran S Niksirat Aghdam niksirataghdamsina@gmail.com 10031947532846002058 10031947532846002058 No Department of Biology, Faculty of Sciences, Islamic Azad University, Qods Branch, Qods, Iran
