"An article published on Jun 4, 2020 reported that The National Task Force on COVID in India recommends the following for health care workers:
"once a week maintenance dose for seven weeks i.e., 400 mg once every week, following the loading dose of 400 mg""It has been noticed that 4th week onwards there is a risk reduction of contracting the Covid-19 virus if the maintenance dosage is being taken as prescribed for seven weeks."
"“simply initiating HCQ prophylaxis did not reduce the odds of acquiring Covid-19 infection among HCWs. However, with the intake of four or more maintenance doses of HCQ, the protective effect started emerging.
A significant reduction of about 80 per cent in the odds of Covid-19 infection in the HCWs was identified with the intake of six or more doses of HCQ prophylaxis. This dose-response relationship added strength to the study outcomes.”"
