50 have tested positive in Tamil Nadu, 24 in Delhi, 21 in Telangana, 18 in Andhra Pradesh, 10 in Andamans and one each in Assam and Kashmir after attending the gathering. 824 foreigners had also travelled to different states and their details had been shared with the police chiefs, the home ministry said.

"We all need to understand and appreciate that this is not the time to do fault finding. What is important for us is to take action as per our containment process in whatever areas we find a case," said Health Ministry Joint Secretary Lav Aggarwal during a press briefing on Tuesday evening.

Ignoring all social distancing rules to avoid the deadly coronavirus, hundreds had been staying in the 100-year-old mosque complex, which has a six-floor dormitory, since March 8. On March 21, there were 1,746 in the centre and 216 were foreigners, according to the home ministry.

The government says 2,137 members of Tabligh have been identified in different states and are being medically examined and quarantined. A search is on for members who returned to Telangana, Andhra Pradesh, Madhya Pradesh, Tamil Nadu, Rajasthan, Jammu and Kashmir and Andamans.

Six people have died in Telangana. A man who died in Srinagar had visited the Deoband seminary in UP. Ten more, who returned to the Andaman and Nicobar Islands, have tested positive. 1,800 are quarantined in Andamans. More than 100 people from Kashmir attended the gathering and Andhra Pradesh is trying to trace 700 members.

The Tablighi Jamaat is an Islamic missionary movement set up in 1926, with members across the world. Similar events held in Malaysia and Pakistan in February-March have been linked to virus cases.

The gathering, which featured sermons, was attended by Tablighi members from Malaysia, Indonesia, Thailand, Nepal, Myanmar, Kyrgyzstan and Saudi Arabia. Members had also come from Afghanistan, Algeria, Djibouti, Sri Lanka, Bangladesh, England, Fiji, France and Kuwait.

300 foreigners who were on tourist visa and attended the religious event, face blacklisting. The government has also decided to not issue tourist visa to any foreigner who wishes to visit India and take part in Tablighi Jamaat activities, officials said.

On March 20, 10 members from Indonesia tested positive in Telangana. Even then, around 1,200 people stayed in the mosque complex. The police claim that they escorted many to the airport. But on March 26, two days into the national lockdown ordered by Prime Minister Narendra Modi, they were back. There were close 2,000 by the time the police found out.
