SUMMARY
The Delta variant of COVID-19, scientifically designated as B.1.617.2, has been classified as a "variant of concern" by the CDC due to its increased transmissibility and potential severity. It is estimated to be 60% more infectious than the Alpha variant and has already spread to over 70 countries, accounting for significant case surges in the UK and other regions. Vaccines, particularly the Pfizer and AstraZeneca, remain effective against this variant, with effectiveness rates of 88% and 71% respectively after two doses. Public health measures are being reconsidered in light of the Delta variant's rapid spread, emphasizing the importance of vaccination.
