The Delta Variant Of COVID-19
The most recent development in the COVID-19 pandemic is the appearance of new mutant strains of the virus. The new strains originate from mutations of the genetic makeup of the original strain as a result of rapid multiplication. Countless strains mutate every day. However, only some of them have been important enough to be identified as more contagious, more deadly, and resistant to the effect of vaccines compared to the original COVID-19 virus.
