Veev

Venezuelan equine encephalitis virus (VEEV) is a mosquito-borne viral pathogen that causes Venezuelan equine encephalitis or VEE. VEEV is a member of the genus Alphavirus in the family Togaviridae. The virus is found in the Americas, particularly in Central and South America, but outbreaks have occurred in the United States.

Transmission

VEEV is primarily transmitted through the bite of an infected mosquito. The virus can also be transmitted from a pregnant animal to her fetus, and in laboratory settings, through aerosols.

Symptoms

In humans, the symptoms of VEE include fever, headache, fatigue, nausea, vomiting, and myalgia. Severe cases can lead to encephalitis, with symptoms such as seizures, coma, and neurological deficits.

Prevention and Control

Prevention of VEEV infection primarily involves control of mosquito populations and avoiding mosquito bites. Vaccines are available for use in horses, but there is currently no licensed vaccine for humans.

Research

Research on VEEV has been conducted due to its potential use as a biological weapon. The virus is classified as a Category B Priority Pathogen by the National Institute of Allergy and Infectious Diseases (NIAID).
