Insights on H5N1 and Its Fatality Rate
H5N1, a variant of avian influenza, has raised significant concern due to its historical fatality rate of about 30-50% when it spills into humans. Continuous monitoring since the late 1990s has indicated its potential for serious human health threats, especially in contexts where it makes contact with livestock, such as dairy cows. Despite fewer cases reported in the U.S., the true fatality rate is likely higher than initially perceived, perhaps between 5-20%, which could pose a far greater risk than COVID-19. This highlights the importance of ongoing surveillance and public health preparedness in addressing potential outbreaks.
