Opinion: Is Covid-19 growing less lethal? The infection fatality rate says ‘no’
Recent reports have suggested that Covid-19 has become markedly less lethal in the United States. Our analysis of death rates and infection fatality rates from Arizona, the U.S. as a whole, and New York City shows it isn’t, indicating that public health measures to reduce infections should not be relaxed.
Determining the true fatality rate can also help identify why more people with Covid-19 are not benefiting from advances in care.
