Viral Infections

                       ----------------



Viral infections in snakes, as a whole, are generally poorly

understood.  This is because viruses are extremely difficult to

detect and identify.  They are equally difficult or impossible to

treat.



Viral infections result in tumorous skin growths in many native

snake species.  Other viruses can cause digestive, respiratory

and nervous system disease among snakes.  An example is a

recently recognized viral encephalitis affecting pythons and boa

constrictors.  Afflicted constrictor species exhibit a very

gradual deterioration of the brain and eventually die.



Most viruses are highly contagious.  Hobbyists must be aware of

this and must quarantine all newly acquired snakes for at least

6-8 weeks.  This involves complete isolation of new snakes and

careful scrutiny of them during this period for any signs of

illness.



All newly acquired snakes should be thoroughly examined and

evaluated by a veterinarian experienced with snakes.  Blood tests

may offer clues as to viral infections.
