The government is focusing its attention on 10 "hotspots" across the country in its effort to control the spread of COVID-19, which has infected more than 1,600 people and claimed at least 38 lives. There are two hotspots each in Uttar Pradesh, Delhi, Kerala and Maharashtra and one each in Gujarat and Rajasthan:
Famed for the shrine of the 14h century Sufi mystic Khwaja Nizamuddin Auliya, the south Delhi locality has emerged as an epicentre for spread of the coronavirus in different parts of the country after thousands of people took part in a Tablighi Jamaat congregation from March 1-15.
Six people who died in Telangana and one in Jammu and Kashmir attended the congregation in the headquarters of the Tablighi in Nizamuddin West, a colony split between the labyrinthine lanes near the 'dargah' and spacious residential homes.
In Delhi alone, 24 participants tested positive for the disease. Besides, 441 of the participants were hospitalised after they showed symptoms. The number is likely to swell significantly as more test reports come.
The northeast Delhi locality made headlines when a woman with a travel history to Saudi Arabia tested positive for coronavirus and infected her daughter as well as two relatives in Jehangirpuri close by.
She also came in contact with a mohalla clinic doctor in Maujpur, who was infected with the disease. The doctor, who is believed have come into contract with hundreds of people, later transmitted the infection to his wife.
"So far, the number of patients in Shahadra district (Dilshad Garden falls under Shahadra district) is 11," said a health department official.
A senior health department official added that they feared the number could have spiked in Dilshad Garden but there has thankfully been no significant rise in the number of patients in the locality. It counts for about 11 per cent of Delhi''s count of more than 100 coronavirus cases.
Of the total 83 coronavirus positive cases detected in Rajasthan, 26 are from the textile town of Bhilwara. Eight patients have tested negative after treatment.
Health department teams have taken 1,194 samples from Bhilwara.
A massive screening exercise is underway with over 26 lakh people in urban and rural areas being screened.
Two coronavirus positive deaths have taken in Bhilwara but officials maintain that they died due to co-morbid conditions.
A doctor of a private hospital was the first positive case in Bhilwara. Most of the cases that have come up so far either are of hospital staff or the patient who had gone for treatment at hospitals.
Gautam Buddh Nagar adjoining Delhi in western Uttar Pradesh has so far recorded 48 COVID-19 cases, the highest for any district in the country''s most populous state.
More than 30 of these cases are linked directly or indirectly to a private firm in Noida which has now been booked for endangering people''s lives and sealed.
An estimated 696 samples have been tested so far and 2,046 people are under surveillance across Noida and Greater Noida, while another 317 have been quarantined at various isolation facilities in the district, local Health Department officials said.

Of the 17 samples tested on Monday, six were declared positive, officials said. Of the six, four are family members of a man who recently returned from Maharashtra. The first COVID-19 case was reported from here last Friday.
After several cases of random people testing positive for COVID-19 emerged on Monday in Mumbai, the state health department declared Koliwada area of Worli and the Goregaon suburb as two hotspots. In Mumbai, the novel coronavirus has claimed eight lives and there are 167 positive cases.

Of 73 coronavirus cases registered in Gujarat so far, the highest number of 23 cases has been detected in Ahmedabad district, mostly in Ahmedabad city.
Ahmedabad city counts for three of six deaths in Gujarat. Of the five persons who have recovered so far, four are from Ahmedabad city.
"Ahmedabad city has been declared as hotspot to prevent spread of the virus in a particular area after a positive case surfaces. Ideally, a three kilometre km area surrounding the residence of that patient is contained for 14 days. It''s like a total lockdown. No one can come inside or go outside except the health staff," said Dr Prakash Vaghela, additional director, Public Health, Gujarat.
Kasaragod is one of the worst affected districts in the country with the number of positive cases standing at 99, while over 7,725 people are under observation. A total of 163 people are in isolation wards.
