AI Article Synopsis

  • The study investigates how COVID-19 mitigation measures affected the spread of seasonal respiratory viruses in sub-tropical climates, specifically in southern Puerto Rico.
  • By comparing data from the 2019-2020 respiratory season with previous seasons (2012-2018), researchers found significant decreases in the test-positivity rates of several viruses, including Influenza A and B, RSV, and adenovirus.
  • The findings suggest that the stay-at-home orders and social distancing during the pandemic may have led to a reduced transmission of these respiratory viruses.

Article Abstract

Introduction: Impacts of COVID-19 mitigation measures on seasonal respiratory viruses is unknown in sub-tropical climates.

Methods: We compared weekly testing and test-positivity of respiratory infections in the 2019-2020 respiratory season to the 2012-2018 seasons in southern Puerto Rico using Wilcoxon signed rank tests.

Results: Compared to the average for the 2012-2018 seasons, test-positivity was significantly lower for Influenza A (p<0.001) & B (p<0.001), respiratory syncytial virus (RSV) (p<0.01), respiratory adenovirus (AdV) (p<0.05), and other respiratory viruses (p<0.001) following March 2020 COVID-19 stay at home orders.

Conclusions: Mitigation measures and behavioral social distancing choices may have reduced respiratory viral spread in southern Puerto Rico.
