People in essential services like bank employees,milk suppliers, commodity suppliers,in eatery services, media personal can be given the prophylactic dose of Hydroxy chloroquine 400 mg twice daily on the first week followed by weekly once 400 mg dose for three weeks by govt. Police personnel, Sanitary workers, post office workers, courier boys can be given prophylactic Corona treatment using Hydroxy chloroquine  by Govts- both central and states. This should be taken up urgently as per ICMR guidelines. For health care workers it should be seven weeks and others also can be extended depending on the need.

This can be supplied in the working place by using vans by local authorities like Collector. By means of this in Tamil Nadu if there is ten lakhs service providers we can prevent Corona in these people. A great step it will be indeed.
