The SARS-CoV-2 virus has mutated, and scientists were able to identify several strains. Each variant has its own characteristics, and to identify them easier, the international community of scientists decided to name them Greek names. More than 25.2% of the world population has received one of the available COBID-19 vaccines, meaning that 3.42 billion doses have already been administered. The statistics also show that, unfortunately, countries with a low income have not benefited from the same accessibility to the lifesaving COVID-19 vaccines, and just 1% of the people from those countries got at least one shot.
The Delta variant is the most dangerous so far.
Several strains have been identified, such as Alpha in the U.K, the Beta, which originated in South Africa, Gamma, which originated from Brazil and Delta, first detected in India. The latter seems to be the most dangerous strain due to its high transmissibility rates and other characteristics. Since new infections with the Delta strain have been identified worldwide, health officials fear a new wave is about to start. Numbers show that this variant is responsible for the recent rise in COVID-19 infections.
Health officials express their concern.
According to a recent interview with CNN, the director of the U.S Centers for Disease Control, Dr Rochelle Walensky, declared that the Delta variant is responsible for most hospitalizations, and it might soon become the dominant variant in the U.S. The only solution available for now is vaccination. She also mentioned that those who are fully vaccinated should not over-worry about the COVID-19 strains, as they are not in danger of losing their lives or receive hospital care. Dr. Walensky is adamant about the importance of vaccination, and she believes it is the only way to control the COVID-19 pandemic. The Delta strain has been in the eyes of worldwide health officials and government as it is difficult to control.
