Trend of respiratory pathogens during the COVID-19 epidemic: comparison between 2020 and the last 5 years

Abstract In China, the first SARS-CoV-2 infection was diagnosed in Wuhan on December 8. Spreads in other regions have occurred since the end of January, happens to be the start of Lunar New Year holiday. In this study, we analyzed the prevalence of common respiratory pathogens in children with respiratory infections during the SARS-CoV-2 pandemic and compared them with the time trends from 2016 to 2019. Overall, results obtained indicate that the time trend of other respiratory infections were significantly different from previous years, especially the pattern of influenza and Mycoplasma pneumonia. Therefore, in the current scenario of COVID-19 pandemic, other common pathogens testing should not be excluded. The natural home isolation period in new year holiday may weaken the transmission of common respiratory viruses.
