We all need to keep in mind that the information we get from time to time about the newly discovered variants is data obtained from very small samples that have been studied in a very short period and these may change in the future with the availability of new data.

It is a common occurrence for any virus to develop mutations when it spreads rapidly. Rarely, a mutation can cause the virus to spread. When such a mutation occurs, it spreads faster than other species.

Covid-19 has been found in several countries since its first diagnosis. For this reason, the disease, which was initially less prevalent, has been observed to spread more rapidly in many countries with the gradual addition of different strains. One of the reasons for this is that the newly added varieties spread more easily among the people than the previous varieties.

In this way, the Delta (B.1.617.2) variant has the potential to spread faster than the current Alpha (B.1.1.7) virus variant.

However, research shows that fully vaccinated individuals are more likely to be protected from this type of Delta (B.1.617.2) variant. No vaccine reduces the risk of infection of any strain by 100%. However, the vaccine currently being used worldwide is suitable for minimizing existing strains as well as severe covid diseases and deaths caused by this new strain.

It is important to understand that the health advice to follow to get rid of corona infection applies to this new variant as well. With the discovery of a new genre that can spread rapidly, more attention needs to be paid to avoiding crowded places as well as closed (non-outdoor) spaces where people can get close to each other.

Like all other varieties, this one may take some time to develop symptoms. The virus may have entered the body without causing any significant symptoms. Therefore, there is a risk of transmitting the disease even from someone you look healthy too. This could be a close friend of yours.

As a result, all non-essential travel arrangements can put you and your loved ones at risk unnecessarily.

Given the current situation, the need to adhere to preventive measures to control the epidemic is more pressing than ever.

We all need to keep in mind that the information we get from time to time about new variants is data obtained from very small samples that have been studied in a very short period and these may change in the future with the availability of new data.
