COVID-19 is spreading at a rapid pace worldwide and most individuals infected with the virus show no or mild symptoms. To contain COVID-19’s spread and keep infections at a manageable level, many countries have instituted lockdowns and social distancing.
In India, a nation-wide 21-day lockdown was announced with effect from 25 March 2020. This lockdown is expected to avert a sudden and large increase in the number of infections in the short term. Additionally, interventions such as social distancing and isolation of infected individuals over several months could reduce peak infections. Interventions such as frequent handwashing, reduced mass gatherings, contact tracing, and quarantines could slow transmission and reduce overall infections.
