World Health Organization has endorsed the lockdown as the most effective strategy to curb the spread of the virus. Most of the nations are now resorting to this social distancing practice that stops all human movement and shuts down transportation and business activities at the cost of economic growth and individual liberty.
However, data shows that the infection reappears soon after easing the controls, re-inducted by an unrecognised link.
Such prospects remain alive until the great majority of the people in a particular society get immune to the pathogen, either through inoculation or by way of herd immunity.
China, which was initially slammed for its heavy-handed imposition of strict lockdown measures in the affected province, has seen a resurgence of the infection just weeks after it declared that it has successfully contained the infection.
In April, China had to place Harbin, a city of 11 million people, under lockdown as an asymptomatic carrier of the coronavirus managed to infect 70 people. The woman had spent 14 days in quarantine and showed no symptoms.
Singapore and South Korea are among other places currently facing a resurgence.
However, the attainment of herd immunity will be a gradual process. In such a scenario, lockdowns help to keep the numbers manageable and prevent the healthcare system from becoming overwhelmed, experts say.
In the meantime, the nations that did not go for lockdowns are also paying a hefty price, with the numbers exploding after a while. Sweden, which initially considered lockdowns as unnecessary, is now seeing its death rates skyrocket. Similarly, Brazil, which disparaged such measures, is seeing a big uptick in infections.
