Tablighi Jamaat Markaz event attendees significantly added to India's Covid-19 cases on Wednesday as state governments continued to trace, quarantine and test those who were present at the congregation between March 1-15. By Wednesday night, the total number of positive novel coronavirus cases in India was 1,998, with at least 58 deaths.

On Wednesday, over 5,000 of those identified to have attended the congregation have been quarantined, including in hospitals across states, while efforts are on to trace another 2,000 including in Gujarat, Tamil Nadu and Telangana.

Experts believe these numbers are likely to go up as several hundred attendees of the religious congregation in south Delhi's Nizammudin area showed symptoms of Covid-19, their test results are awaited.

Meanwhile, the common people continued to suffer on Day 8 of the nationwide lockdown as essential commodities remained in short supply across the nation. While shopkeepers blamed it on the absence of supply chain, the government assured that it was working to ensure that at least 2 lakh trucks ply on the roads by Thursday, delivering essential food items and medicines.

Here are all key developments on Covid-19 outbreak in India:

Largest single-day spike

India on Wednesday reported at least 387 new cases with at least 11 deaths. The number of recovered patients increased from 153 to 159. With over 300 cases reported in a day, it is the largest single-day spike in Covid-19 cases for India.

Authorities attributed the big spike in the numbers of confirmed coronavirus cases largely to the Tablighi Jamaat, an orthodox Muslim society set up nearly 100 years ago by Deobandi Islamic scholar Maulana Muhammad Ilyas Khandhalawi as a religious reform movement and to spread the faith.

The latest Union Health Ministry update put the nationwide tally of the confirmed COVID-19 cases at 1,637 after 376 new cases were recorded in the last 24 hours and the death count at 38. But figures announced by different states and union territories totaled 1,998 with at least 58 deaths.

The ministry officials said cases have increased largely due to Tablighi Jamaat congregation, which took place in mid-March, and therefore technically it does not show a national trend. They urged people to follow guidelines during the lockdown period and avoid congregations, including religious gatherings.

Maharashtra, Tamil Nadu and Delhi were among the places to report a large number of new cases.

Maharashtra reports 5 out of 11 deaths

The western state is among the worst-hit regions by the Covid-19 outbreak in India. On Wednesday, Maharashtra registered six out of a total of 12 casualties to the disease.

In Delhi, the authorities said coronavirus cases have risen to 152, including 53 who attended the Nizamuddin congregation.

The number in Maharashtra increased by 33 to 335 on Wednesday, including 30 in Mumbai alone. The tally can increase further as nearly 5,000 quarantined persons are in the high-risk category, according to the state government.

The Centre on Wednesday also asked all states and Union Territories to launch on a "war footing" the contact tracing of all participants of the Tablighi Jamaat congregation in Delhi's Nizamuddin, which has emerged as the coronavirus hotspot.

In a video conference with chief secretaries and DGPs of all states and Union Territories (UTs), Cabinet Secretary Rajiv Gauba also asked them to take action against foreigners, who participated in the missionary activities of the Tablighi Jamaat, for violation of visa conditions.

Fresh cases of infection reported on Wednesday included some doctors, CRPG personnel and a police constable as well.

Essential commodity battle

The essential commodity supply continued to pose a challenge for the Centre and state governments on Wednesday, even as the nation entered Day 8 of the lockdown. India Today TV ground report revealed that several people continued to face problems due to lack of essential goods and medicines at retail stores, while doctors at some hospitals raised red flags over the supply of personal protective gear or PPE, essential while treating highly contagious patients.

For the groceries, the government has assured that it was working to bring out at least 2 lakh trucks of essential goods on the roads by tomorrow.

For the PPEs, a senior health ministry official on Wednesday told media that the Centre was working to import the equipment while also looking at some indigenous solutions.

To boost the availability of medical facilities for novel coronavirus patients, the armed forces have made available over 9,000 hospital beds and more than 8,500 doctors and support staff across the country, while Railways has also converted some of its coaches into isolation wards.

India is looking at South Korea, Germany and China for procurement of cutting-edge technology and adopting best practices being followed by them in successfully containing the spread of coronavirus amid looming risk of the country entering the community infection stage of the pandemic.

PM Modi to hold meeting with CMs

Amid heightened efforts to contain the pandemic, Prime Minister Narendra will also hold a video conference with all chief ministers on Thursday during which issues such as ways to contain the spread of COVID-19, movement of migrants and contact tracing of Tablighi Jamat participants are likely to come up for discussion, sources said.
