| Abstract
Background and Aims: Coronaviruses cause upper respiratory ailments and sporadically lower tract sickness in vulnerable populations. This study examined the prevalence of six human coronaviruses, including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), OC43, 229E, HKU1, NL63, and Middle East respiratory syndrome coronavirus (MERS-CoV) during the 2019 pandemic caused by SARS-CoV-2 in Tehran, Iran.
Material and methods: Specimens were collected from 204 adult patients with acute respiratory illness. The specimens were examined for the presence of six human coronaviruses using consensus and subtype-specific Real-time reverse-transcription polymerase chain reaction (PCR) assays. The demographic and clinical characteristics associated with coronavirus infection were examined retrospectively.
Results: Coronaviruses were identified in 204 adult patients. The gender ratio was 104/100 male and female, respectively. HCoV-229E, HCoV-NL63, HCoV-OC43, HCoV-HKU1, MERS-CoV, and SARS-CoV-2 were detected in 0.5%, 1.0%, 4.0%, 7.4%, 0.0%, and 22.5% of patients, respectively. The acute clinical features were similar across subtypes. There was no report of fatality incidence among the population during the investigation period.
Conclusions: HCoVs could play a significant role in causing upper respiratory tract infections among adults and older children. Based on the findings of this study and those of others, more extensive studies using other diagnostic methods and higher sample sizes are suggested.
