COVID-19 pandemic affected over 227 countries with more than 147 million infections
that claimed 31.22 lacs lives. The first case of the pandemic was reported from China in Dec, 2019
showing pneumonia like symptoms that turned out to be the novel strain of coronavirus (2019-n-
CoV). The WHO declared 2019-nCoV infection as the Public Health Emergency of International
Concern and the disease named coronavirus disease (COVID-19). The infection curve of the pandemic
has been flattened in many countries around the world, but the effective new antiviral drugs
or vaccine has not yet developed. So far, we are saved by non-pharmaceutical interventions like
handwashing, social distancing, quarantine, masks and health-care workers by personal protective
equipments. Now the question arises that what we do if no effective drug or vaccine emerges? In
the absence of effective drug/vaccines, pandemic has to be fought at community level not at hospitals.
For such emergent situations, we need a ‘Plan B’ based non-vaccine/drug interventions.
