The nationwide coronavirus lockdown will be extended by two more weeks from May 4, the government said today, noting significant gains from the six-week shutdown in India's fight to slow the spread of COVID-19. Extending the lockdown for the second time, the home ministry announced new guidelines based on the demarcation of the country into red zones with "significant risk of spread of the infection"; green zones with either zero cases or no confirmed cases in the past 21 days; and those in between as orange.
