NEW DELHI: With a new cluster of coronavirus infected cases emerging in Wuhan and some countries reporting a sudden rise, India has revised its travel advisory asking people to avoid all non- essential travel to Singapore. The government also extended screening of passengers from four more countries - Kathmandu, Vietnam , Malaysia and Indonesia from Monday, in addition to six countries earlier.The decisions were taken in a high level review meeting chaired by the cabinet secretary on Saturday.Currently, passengers from China, Hong Kong, Thailand, South Korea, Singapore and Japan are screened at 21 designated airports in the country for a possible exposure to the novel coronavirus.“In furtherance to the travel advisory issued earlier, citizens are advised to avoid all non-essential travel to Singapore,” the health ministry said.As on date, 21,805 passengers have been brought under community surveillance. In addition, 3,97,152 flight passengers and 9,695 travellers at sea ports have been screened, it said.After a detailed review, in addition to the screening as per earlier advisories, universal screening at airports is now being planned for flights from Kathmandu, Indonesia, Vietnam and Malaysia from Monday, the ministry said.Secretaries of ministries of health, civil aviation, defence, information and broadcasting (I&B), representatives from external affairs ministry, home ministry and other related departments were present in the meeting.Even as China reported a sharp fall in deaths from cases of the coronavirus on Saturday, world health officials warned it was too early to make predictions about the outbreak as new infections continued to rise in other countries.Chinese authorities said the mainland had 397 new confirmed cases on Friday, down from 889 a day earlier. The numbers surged elsewhere, though, with outbreaks worsening in South Korea, Iran , Italy and Lebanon.In total, China has reported 75,569 cases and 2,239 deaths to the World Health Organisation due to the virus since December.The disease has spread to some 26 countries and territories outside mainland China.
