A new paper by @davidsimons: "Lassa fever cases suffer from severe underreporting based on reported fatalities."
Using current estimates of case fatality and severe outcome rates, he calculates the gap between expected and reported sever cases: "The expected number of severe cases between 2012 and 2022 is 8995, with current reported numbers 58% of what is expected."
