Symptoms

Transmission

Medical relevance

In the United States, about 80–100 LACV disease cases are reported each year, although it is believed to be under-reported due to minimal symptoms experienced by many of those affected.

LAC encephalitis is rare. Death from LAC encephalitis occurs in less than 1% of clinical cases

Toolbox

The toolbox for this virus is currently in development. Please contact us via info@virusbankplatform.be for more information.
