Nipah virus (NiV) is a pathogenic paramyxovirus that has been responsible for sporadic outbreaks of respiratory and encephalitic disease in tropical countries. Elevated case mortality rate has also been connected with recent outbreaks in India (Kerala), Malaysia and Bangladesh. The virus generally infects animals like pigs and bats, but they do not show any symptoms of NiV. The mortality rate in NiV infected humans is more as compared to other mammals. The patient usually shows no symptoms to headache fever, cough, dyspnea, confusion and more consequences lead to a coma. Although there are no drugs or vaccines available against this severe disease, precaution and awareness reduce the risk of NiV-infection. This review will be helpful to save the life of people and decrease death by the NiV-infection outbreak. Keywords: Diagnosis, Henipavirus, Nipah virus, Prevention and treatment
