Distribution of spreading viruses during COVID-19 pandemic: Effect of mitigation strategies.

ABSTRACT

BACKGROUND: The study aimed to evaluate the distribution of circulating respiratory viral pathogens other than severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) during the first year of the coronavirus disease-2019 (COVID-19) pandemic with especially focusing on the effects of the national-based mitigation strategies. METHODS: This single-center study was conducted between March 11, 2020-March 11, 2021. All children who were tested by polymerase chain reaction on nasopharyngeal swabs for SARS-CoV-2 and other common respiratory viral pathogens were included in the study. RESULTS: A total of 995 children with suspected COVID-19 admitted to the study center. Of these, 513 patients who were tested by polymerase chain reaction for both SARS-CoV-2 and common respiratory viral pathogens were included in the final analysis. Two hundred ninety-five patients were (57.5%) male. The median age was 3 years of age (27 days-17 years). A total of 321 viral pathogens identified in 310 (n 310/513, 60.4%) patients, and 11 of them (n 11/310, 3.5%) had co-detection with more than 1 virus. The most common detected virus was rhinovirus (n 156/513, 30.4%), and SARS-CoV-2 (n 122/513, 23.8%) followed by respiratory syncytial virus (n 18/513, 3.5%). The influenza virus was detected in 2 patients (0.4%). A total of 193 patients were negative for both SARS-CoV-2 and other pathogens. CONCLUSIONS: There is a decline in the frequency of all viral pathogens like SARS-CoV-2 in correlation with the national-based mitigation strategies against COVID-19 during the pandemic.
