Study shows lower case-fatality rate in COVID-19 second waveA new study in Transboundary and Emerging Disease calculated the case-fatality rate (CFR) of COVID-19 infections in 53 countries or regions that experienced a second wave—or resurgence—of coronavirus activity, and found a significantly lower death rate among all confirmed cases than in the first wave.This is the first study to compare the CFR in the first and second waves of the pandemic.
Researchers from Hong Kong based the study on daily confirmed COVID-19 cases and deaths for 216 countries or regions, during February of 2020 through August 2020, and weekly influenza confirmations during 2015 to the current week of 2020, from the World Health Organization (WHO).
