Elephant endotheliotropic herpesviruses (EEHV) or Elephantid betaherpesvirus 1 (ElHV-1) is a type of herpesvirus, which can cause a highly fatal hemorrhagic disease when transmitted to young Asian elephants.
The four deaths in Nandan Kanan Zoo are the first reported cases of EEHV-related deaths in an Indian zoo
Most elephants carry just as most humans carry a cold virus. When EEHV is triggered, the elephant dies of massive internal bleeding and symptoms which are hardly visible
Some elephants show symptoms such as reduced appetite, nasal discharge and swollen glands
There is no true cure for herpesviruses in animals or in humans, because herpes viruses go latent.
EEHV is lethal for young elephants between the ages of one and 12. If a young elephant dies before reproducing, it affects the population of the species as a whole in the concerned geography.
In India, the CZA will set up a national committee of scientists from Guwahati, Kerala, IVRI and Nandan Kanan to develop protocols for the country lest an EEHV outbreak occurs elsewhere in the future.
