"At the moment they're thinking it's not so well transmitted between people, but it's very very early days", she said.
The clinical signs and symptoms are mainly fever with a few patients having difficulty in breathing, the Indian travel warning said. Three overseas infections have been reported, two in Thailand and one in Japan.
The Chinese Center for Disease Control and Prevention said the virus is not severe acute respiratory syndrome, or SARS, and denied that hospitals outside of Wuhan had been secretly treating people infected with the virus.
Those countries are among at least half a dozen in Asia, as well as New York's JFK, San Francisco and Los Angeles airports in the United States that have started screening incoming airline passengers from central China.
Wuhan's open seafood market has been closed since the outbreak, the MRC said.
Wuhan officials have been providing updates on new cases nearly daily since 11 January, and 17 is the highest number reported since then.
Health officials say there is no clear evidence that the virus spreads easily from one person to another, but they can not completely rule out the possibility of human-to-human transmission.
Most cases have been linked to the Huanan Seafood Market (also known as Wuhan South China Seafood City and South China Seafood Wholesale Market), which was closed as of January 1 for cleaning and disinfection.
Some experts have suggested that there are most likely far more cases of the illness than the authorities have disclosed.
According to diagnoses by the Wuhan Municipal Health Commission, 62 people infected are suffering from pneumonia caused by the coronavirus.
Initially it was suspected that Ms Maheshwari may have been suffering from a new type of coronavirus.
More than 200 cases of the new coronavirus, a SARS-like illness, have been reported throughout China.
The United States and most Asian countries have stepped up screenings of people travelling from Wuhan and the World Health Organization has warned hospitals worldwide that a wider outbreak is possible.
"Entry screening alone is not a guarantee against the possible importation of this new virus but is an important public health tool during periods of uncertainty and part of a multilayered government response strategy", said the statement.
News about the outbreak was trending on Weibo, a microblogging platform in China, on Sunday morning.
Most patients are experiencing mild symptoms, Li said, and no related cases have been found in more than 700 people who came into close contact with infected patients.
