Delta variant is highly contagious
Around 80 percent of the new COVID cases in the United States are Delta infections. As of July, this COVID-19 variant became the dominant strain in the US, being two times more contagious than the virus’s previous variants, according to the Director of the Centers for Disease Control and Prevention, Rochelle Walensky.
In fact, experts warn that Delta is spreading 50% faster than Alpha, which was 50% more contagious than the original strain of SARS-CoV-2. In a group of unvaccinated people, a person infected with the original strain would spread it to 2.5 other people; on the other hand, in the same situation, the Delta variant would infect 3.5 or 4 other people.
