By Hemanshi Kamani  MUMBAI, May 28 (Reuters) – As India’s financial capital Mumbai battled a growing number of coronavirus cases, local DJ Sanjay Meriya set aside his turntable and dusted off a long-unused medical degree in order to help out.  Meriya, 30, known as The Spindoctor in Mumbai music circles, began work last month as a medical volunteer after spotting a government newspaper ad asking for help.  He has chiefly been visiting a slum in one of Mumbai’s worst-hit suburbs, clad in a protective suit and gloves, to instruct local residents about the precautions they should take to ward off the coronavirus. “I’m very patriotic. I can battle this way (as a doctor),” Meriya, who signed up as a volunteer for at least three months, told Reuters.  Mumbai accounts for more than 32,000 of India’s 150,000 cases of the coronavirus, making it the worst-hit city. With government hospitals short of beds and health officials overworked, volunteers like Meriya are all the more important.  Meriya began to dabble in DJing as a hobby at around the age of 20 while studying for his medical degree, but said it then “took over me” – much to his family’s dismay. “They hated it. They still hate it,” he said of his decision to devote himself to being a DJ.  Although worried about his potential exposure to the virus, Meriya’s family is thrilled to see him back in medicine. “They now have a lot to share with all our relatives, if you know what I mean when it comes to Indian families,” he said.
