As many as 21 Italian nationals and three Indians were under ITBP’s quarantine facility at Chhawla near Delhi of which 14 tested positive today. An Indian is also among those who have tested positive, the officials said.

Suspecting the emergence of cluster cases of the virus, India has stepped up the level of preparedness against coronavirus.

The 12 countries that were earlier under the scanner for possible spread of the infection included China, Malaysia, Singapore, Thailand, Hong Kong, Japan, South Korea, Vietnam, Italy, Nepal and Iran.

While over 10 major and more than 50 minor seaports across the country are being screened, as many as 21 major airports are also conducting screenings.

More than 5 lakh people have been screened at the airports so far.
