The first avian picornavirus to have its genome sequenced, [3] it causes epidemic tremor in chickens. Tremovirus is of economic importance to chicken farmers because it causes a drop in egg production in laying hens, and neurological diseases in chicks less than three weeks old.
Treatment is usually supportive in nature while also providing antiviral drug therapy. The primary exception to this is herpes simplex encephalitis, which is treatable with acyclovir . Prognosis is good for most individuals who are infected by an encephalitic virus but is poor among those who develop severe symptoms, including viral encephalitis.

H5N1 continually mutates, meaning vaccines based on current samples of avian H5N1 cannot be depended upon to work in the case of a future pandemic of H5N1. While there can be some cross-protection against related flu strains, the best protection would be from a vaccine specifically produced for any future pandemic flu virus strain.
The state supplies roughly 20% of the nation's milk, is home to about 1,300 dairy farms and has an estimated 1.7 million dairy cows. Most human influenza viruses are seasonal, arriving in the fall ...
Venezuelan equine encephalitis virus is a mosquito-borne viral pathogen that causes Venezuelan equine encephalitis or encephalomyelitis (VEE).
