An internal presentation by the US Centers for Disease Control and Prevention has stated that the Delta variant of the coronavirus is much more contagious, has a greater likelihood of evading protection provided by the COVID-19 vaccines, and may even cause more severe disease compared to other known versions of the virus, reported the New York Times.

The document states that the Delta variant is more contagious than the viruses that are known to cause MERS, SARS, Ebola, common cold, seasonal flu, and smallpox, and appears to be as transmissible as chickenpox, reported the newspaper.
