Officials across India are searching for hundreds of people who attended a religious event in the capital that has set off several Covid-19 clusters.
At least six regions have reported cases that can be directly traced to the days-long congregation at a mosque.
Delhi officials are now clearing the building, where more than 1,000 people have been stranded since the government imposed a lockdown last week.
At least 24 have tested positive so far, the state health minister said.
They are among some 300 people who showed symptoms and have been moved to various hospital to be tested, he told the media. Another 700 have been shifted into quarantine centres, he added.
It is believed that the infections were caused by preachers who attended the event from Indonesia.
State officials have called for action to be taken against mosque officials, but they have denied any wrongdoing.
Local media reports say that Nizamuddin – the locality where the mosque is located – has been cordoned off and more than 35 buses carrying people to hospitals or quarantine centres.
The congregation – part of a 20th Century Islamic movement called Tablighi Jamaat – began at the end of February, but some of the main events were held in early March.
It’s unclear if the event was ticketed or even if the organisers maintained a roster of visitors as people attended the event throughout, with some staying on and others leaving. Even overseas visitors, some of them preachers, travelled to other parts of the country where they stayed in local mosques and met people.
So officials have no easy way
