The latest available data, the authorities highlight, show how immunized people can transmit it like unvaccinated people
The Delta variant is much more contagious, is more likely to overcome the protections developed by vaccines, and can cause more serious disease than all other known variants of Covid-19. This is the alarm that emerges from an internal report drawn up by the Centers for Disease Control and Prevention (Cdc).
The Delta variant – the American health authorities point out – is more transmissible than the viruses that cause Mers, Sars, Ebola, the common cold, seasonal flu and smallpox, and is as contagious as chickenpox. Furthermore, the latest available data show how immunized people can transmit it like unvaccinated people. The next step in the strategy to counter it, according to the CDC, is for the government to “recognize that the war has changed”.
