An advisory issued by state health secretary Rajeev Sadanandan stated that travelling to any part of Kerala was safe.

But if travellers wished to be extra cautious, they could avoid the four districts Kozhikode, Malappuram, Wayanad and Kannur, it said.

"A few cases of infection by nipah virus have been reported from Kozhikode district in Kerala. The infection remains highly localised, all cases being linked to one family," the advisory said.

Surveillance by the government is being conducted in Kozhikode district, from where most of the cases were reported, and in the neighbouring districts of Malappuram, Wayanad and Kannur, it said.

"The health department is taking effective steps for management of reported cases and surveillance through tracing of the contact of these persons. The situation remains under control," the advisory said.

Meanwhile, 2,000 Ribavirin tablets, an antiviral medicine, have already reached Kozhikode.

Another batch of 8,000 tablets are expected to be delivered later in the day, Health department sources said.

Ten people have died of nipah virus so far in Kozhikode and Malappuram districts.

Two others who died of high fever are suspected to have contracted the virus, too.

Nipah virus (NiV) infection is a newly-emerging zoonosis that causes severe disease in both animals and humans.

The natural host of the virus are fruit bats, of the Pteropodidae family, Pteropus genus.

The virus can cause flu-like symptoms and brain damage, and the outbreak has already killed 10 people in southern India, with at least nine more being treated, officials said.

Meanwhile, Indian health officials were checking on Wednesday if a rare, brain-damaging virus had spread to a second state after two suspected cases reported in southern Karnataka, as the death toll in adjacent Kerala, where the outbreak began, rose to 11.

The world's second most populous country suffers hundreds of deaths from infectious diseases every year because of weak disease surveillance and infection control systems, leading health experts to worry about the risks of such outbreaks.

There is no vaccine for the Nipah virus, carried by fruit bats and spread through contact with bodily fluids, the World Health Organisation (WHO) says. Treatment for the virus, which has a mortality rate of about 70 per cent, is supportive care.
