At present, the delta mutant strain has been circulating in more than 130 countries and regions.

To make matters worse, new mutant strains continue to emerge.

Another variant called Lambda has spread widely.

So far, the WHO has named 11 COVID-19 variants with Greek letters, and 13 other names have not been used, including Sigma, Omega, etc.

According to the WHO, if the Greek letters are used up, the mutant strains may be named after the stars.

Let us get vaccinated and wear masks to help stop the virus from mutating and let the stars go!
