Vardhan has urged the passengers who have a travel history to China since January 1, 2020, to report to their nearest health facility if they experience any symptoms such as fever, cough, respiratory distress, etc.
On Saturday, the Union Health Ministry also issued a fresh advisory asking the passengers to follow certain dos and don'ts if they are in China or travelling or returning from China.
The advisory stated that during their stay in China, if they feel sick and have fever and cough, they should cover their mouth while coughing and sneezing, seek medical attention promptly and report to the Indian Embassy in China.
The advisory also said that if they feel sick on flight while travelling back to India from China, they should inform the airline crew about their illness, seek mask and self-reporting format from the airline crew.
In such a case, the advisory said, avoid close contact with family members or fellow travellers and follow other directions of crew and airport health officer.
According to the advisory, 28 cases have been confirmed outside Chinese mainland -- 5 in Hong Kong, 4 in Thailand, 3 each in Taiwan and Singapore, 2 each in Macao, Japan, South Korea, United States and Vietnam, and 1 each in Nepal and France.
