Centers for Disease Control and Prevention (CDC) data show that cases of the COVID-19 variant first detected in Brazil are on the rise in the United States. According to the data released last Thursday, there are 434 reported cases of the P.1 variant across 28 jurisdictions. According to the CDC, this variant detected first in the United Kingdom is now the most dominant strain of the virus in the U.S. That variant spreads more easily and can cause more spikes in infections.
