Nipah Virus

There is growing fear that Nipah Virus has crossed border from Kerala to Karnataka. Two people suspected to be infected with the brain-damaging Nipah virus are under treatment in Karnataka, a health official said. The rare virus has killed at least 11 people in adjacent Kerala.

There is no vaccine for the virus yet, says the World Health Organisation. The main treatment for those infected is "intensive supportive care", according to the UN health body.
