Officials said the civil aviation ministry will also ask the airlines to make in-flight announcements and distribute "health cards" to all flights with direct or indirect connectivity to China.
Union Health Secretary Preeti Sudan has asked chief secretaries and police chiefs of the five states bordering Nepal -- Uttarakhand, Uttar Pradesh, Bihar, West Bengal and Sikkim to review their preparedness for prevention and management of the coronavirus, news agency PTI reported.
The virus has caused alarm because it is still too early to know how dangerous it is and how easily it spreads between people. Also because it is new, humans have not been able to build immunity to it. Scientists hope to be testing the first possible vaccines in three months' time. China is testing the HIV drug Aluvia as a treatment.
There are severe travel restrictions in Wuhan, with urban transport shut and outgoing flights suspended. Among other measures to contain the virus, China will halt all group tours, affecting tourism both at home and to other countries, from today.
The new virus has caused alarm because of its similarity to SARS, which killed nearly 800 people in mainland China and Hong Kong in 2002-03.
