After two out of a group of 23 tourists who arrived in the country last month tested positive in the western state of Rajasthan, the other 21 were put under quarantine in a special facility in New Delhi on Tuesday.
“Out of the 21 tourists, 15 have been tested positive for coronavirus. We are awaiting test results of the others,” the source said on condition of anonymity.
Worldwide around 3,200 people have died from the virus with more than 90,000 infections, with China, South Korea, Italy, Iran and Japan the worst affected.
India has now stepped up preventative measures including barring visitors from Italy, Iran, South Korea and Japan, except diplomats and officials from international bodies.
“There is no need to panic. We need to work together, take small yet important measures to ensure self-protection,” Prime Minister Narendra Modi tweeted on Tuesday.
“Had an extensive review regarding preparedness on the COVID-19 Novel Coronavirus. Different ministries & states are working together, from screening people arriving in India to providing prompt medical attention,” he said.
