Venezuelan
Equine Encephalitis
This is a mosquito-borne viral disease affecting rodents, horses,
and people in Trinidad, Central America, Florida, and South America.
Epidemics occur during rainy seasons.
After an incubation time of less than a week, a flu-like illness
with fever, chills, nausea, vomiting, and diarrhea, will occur.
The fever lasts up to 4 days but is followed by profound weakness
of up to several weeks. Some people develop encephalitis.
Antibody tests confirm the diagnosis. There is no specific treatment,
only supportive measures. A vaccine exists for lab personnel, but
is unavailable to travelers as the disease is rare.
This is one disease the U.S military is concerned with being weaponized
by terrorists because it incapacitates people, although there is
no firm evidence of this having ever happened.
