The U.S and many countries over the world are struggling to keep under control the SARS-CoV-2 Delta strain that originated in India last year. The Delta variant has already been labeled as dangerous and with a higher transmissibility rate than other variants. According to the CDC, more than 83% of daily new infections in the U.S are with the Delta strain, and many states have seen a surge in hospitalizations due to the infection, such as Texas.
CDC document: The Delta strain is much more dangerous and severe
According to recent articles, an internal presentation of the CDC shows that the Delta variant causes severe illness in infected people. The transmission rate of the infection with this strain is compared to other highly transmissible infections such as chickenpox. Another reason why this variant has spread so quickly is the fact that many people in the U.S are still quite hesitant to get Covid-19 vaccines.
New restrictions might be necessary to stop Covid-19 outbreaks
The internal presentation also mentions that wearing masks indoors and convincing people to get the vaccines are urgent measures that need to be taken. Some states in the U.S, such as California and Washington, have already requested residents to wear masks in indoor public places, even for fully vaccinated people. The message for the public is still the same; only vaccination can help us fight the coronavirus.
Fully vaccinated people might still transmit the Covid-19 virus
The same source mentioned that unpublished CDC data shows that even those fully vaccinated can get infected with the Delta strain and transmit the virus to other people just as easily as unvaccinated people. This might be the reason why the CDC has published new guidelines for fully vaccinated people.
