Letalidad

¿Se puede calcular la letalidad (del coronavirus, digamos) sin el análisis de la supervivencia?

Pues no lo sé. Pero con él, sí, según Methods for estimating the case fatality ratio for a novel, emerging infectious disease: During the course of an epidemic of a potentially fatal disease, it is important that the case fatality ratio be well estimated. The authors propose a novel method for doing so based on the Kaplan-Meier survival procedure, jointly considering two outcomes (death and recovery), and evaluate its performance by using data from the 2003 epidemic of severe acute respiratory syndrome in Hong Kong, People’s Republic of China.
