Indian American doctors pitch in with free telehealth advice during India's Covid-19 crisis

But as the avalanche of Covid-19 deaths and cases continues to cripple the health care system during the second wave, the doctors are going beyond helping just family and friends.

Some of them are now staying up nights, when it is daytime in India, to advise other coronavirus patients and raise money for medical supplies.

CNN spoke to some doctors who are helping coronavirus patients in India from afar.

Emotional when speaking about him, Garimella said his brother was the anchor of the whole family, and said other family members are also sick with Covid-19.

He and other doctors are working together to try to help any Covid-19 patient in India who reaches out for help.

Sreeni Gangasani's family, including his parents and brother in India, all contracted Covid-19, yet he was able to help them via Whatsapp and video calls so that they were able to manage their symptoms at home and did not have to go to the hospital.

That's when he and other doctors such as Garimella decided to provide free medical advice for Indian patients with Covid-19 via the website, partnering with the American Association of Physicians of Indian Origin (AAPI) and the non-profit Sewa International to provide this service.

Inundated with Covid-19 patients

To get medical advice, coronavirus patients in India must fill out an online form, after which they are connected by volunteers via Zoom to a doctor in the US.

He said all the doctors and volunteers are working pro bono for the India crisis.

Jonnalagadda added that the oxygen concentrators and other medical supplies they are sending to India are being distributed with the help of Sewa International.

"It's not just the money, but how well we can convert it into lives is the most important thing.

Guntapalli said at least 15 people in her extended family got Covid-19 in India and she is giving medical advice to family and friends there every day.
