The Delta variant is a version of the coronavirus (COVID-19). As of June 2021, the Delta variant has reached 74 countries – just 6 months after discovery in India. Many health officials are concerned about its impact because it can spread quickly and easily. In fact, Dr. Anthony Fauci, U.S. infectious disease expert, stated that the Delta variant is “the greatest threat to the United States’ effort to eradicate COVID-19 in its borders.” It appears that this variant can spread more easily than the original variant of COVID-19.

Delta variant infection causes worse symptoms

Getting infected with the Delta variant is linked to worse health complications. For example, people may be more likely to end up in the hospital if they have the Delta variant. Studies suggest it may have almost double the risk of hospitalization than other variants. Also, it seems to affect younger people more often. In the United Kingdom, studies showed that children and adults under 50 years were 2.5 times more likely to become infected.

How to protect yourself

Getting vaccinated is the best way to protect yourself. For example, studies looking at the Pfizer vaccine found that 2 doses can provide 79% protection against Delta variant infection. Also, vaccines seem to be 88% effective against symptoms if infected.
