The case fatality rate of NiV ranges from 40- 70% although it has been as high as 100 per cent in some outbreaks. In 2018, 18 cases and 16 deaths have been reported from Kozhikode and Malappuram districts of Kerala", the circular read. It also cited reports of a 23-year-old student from Kerala being tested positive for the disease while stating that surveillance activity has to be strengthened.

The circular has directed that an interdepartmental co-ordination committee meeting be convened immediately including officials from the veterinary department, IMA, and IAP, in districts which are vulnerable to the virus namely Chamarajanagara, Mysuru, Kodagu, Dakshina Kannada, Uttara Kannada, Udupi, Shivamogga and Chikkamagaluru. The government has also asked for identifying two isolation beds to isolate suspected human case and for making sure all necessary logistics are available at all levels.
