It is feared hundreds of Indians could contract the deadly coronavirus after coming into contact with an infected Italian tour group.

16 members of the group and their Indian driver tested positive for coronavirus today as India recorded its biggest jump in cases, surging to 30 from six on Monday.

Local media reported the tour visited six states after arriving on February 21, including Rajasthan, with the Indian Government scrambling to establish their exact route.

It is believed members of the tour group were infected before leaving Italy, which is enduring Europe's largest outbreak with over 2,000 confirmed cases.

They are receiving treatment in a remote quarantine facility run by the Indo-Tibetan Border Police.

In addition to the Italians, six new cases have been confirmed in the city of Agra and two in the southern state of Telangana.

The cases in Agra are family members of an Indian software engineer who tested positive for coronavirus on Monday in New Delhi after a visit to Italy.

A second Indian software engineer tested positive for the virus in the southern state of Telangana on Monday after a work trip to Dubai.

It has not been confirmed whether today's two new cases in the state are linked although the infected individual came into contact with approximately 100 people before becoming unwell.
