All-india strike by doctors is intensifying. After day-long protests, doctors across the country are going on strike once again on Monday. The Indian Medical association has called the protest on Monday to press for a Central law against violence on medical professionals. Union Health Minister Harsh Vardhan sent a letter appealing to West bengal Chief Minister to mediate with the agitating doctors in bengal where it all began. The Calcutta High court also asked the state govt to persuade doctors to rejoin work.
