Should the Global Community Be Concerned About the South African Variant?
February 23, 2021
Currently, the downward trend of SARS-CoV-2 infections per day in the U.S. is continuing, and the case numbers of COVID-19 are less than half of what it was at the peak of the pandemic (Worldometers).The mortality rate of COVID-19 is also beginning to decrease in the U.S., and similar trends are evident in many other countries as well. It’s not entirely clear what’s causing this downtrend in infection rates, though it may be related to increased compliance with preventive precautions. It is much too early to be due to vaccination and, in fact, the decrease is being observed in countries with a very low pace of vaccination or no vaccination. The new trend may also reflect, in part, natural immunity following up on large scale infection in some populations. However, the downtrend is likely a combination of all these parameters, yet no one definitively knows the cause. Viral-induced pandemics follow cyclic evolutions that we cannot control.
