Counties with highest COVID-19 infection rates in Massachusetts
Counties with highest COVID-19 infection rates in Massachusetts
The vaccine deployment in December 2020 signaled a turning point in the COVID-19 pandemic. By the end of May 2021, 40% of the U.S. population was fully vaccinated. But as vaccination rates lagged over the summer, new surges of COVID-19 came, including Delta in the summer of 2021, and now the Omicron variant, which comprises the majority of cases in the U.S.
Researchers around the world have reported that Omicron is more transmissible than Delta, making breakthrough and repeat infections more likely.
The United States as of Nov. 16 reached over 1 million COVID-19-related deaths and 98.1 million COVID-19 cases, according to Johns Hopkins University. Currently, 68.6% of the population is fully vaccinated, and 10.1% of vaccinated people have received the most recently available bivalent booster doses.
