Coronavirus Variants of Concern: An Insight

The new coronavirus, SARS-CoV-2, which causes the disease COVID-19, has had a serious worldwide impact on human health. The virus was virtually unknown at the beginning of 2020. Since then, intense research efforts have resulted in sequencing the coronavirus genome, identifying the structures of its proteins, and creating a wide range of tools to search for effective vaccines and therapies. Also, there’s a chance that the COVID-19 contraction rate could get higher than the COVID-19 vaccination rate. In other words, the virus continues to spread while very little people actually get vaccinated. This only makes the job of scientists even harder. In order to stop the spread of COVID-19, citizens must get vaccinated more frequently than citizens are contracting COVID-19. The coronavirus attacks and kills healthy cells, causing detrimental damage to the respiratory system and immune system. It was then discovered that COVID-19 can be terribly fatal for those with already fragile immune systems and preexisting health conditions. Back in March, when COVID-19 was clearly becoming a critical threat to many countries around the world, the evidence indicated that the virus spreads from person to person through small respiratory droplets produced when people cough or sneeze, or even breathe. Surfaces can serve as an intermediary for the virus when looking for a host. Instead of contracting the virus directly from a person, it is possible to receive the virus from touching an object that an infected person sneezed on. It has been discovered that the virus can last up to three 3 days on a surface. Proceeding to rub one’s eyes, mouth, or nose after such contact is also a mode of transmission.
