Monitoring variants is important because of the possibility that they could make vaccines and treatments less effective, or change the way they infect people. How many variants are there of the COVID-19 virus? The vaccine should protect against both but is less effective on the latter, research suggested. Coronaviruses are named for the crown-like spikes on their surfaces. President Biden has even instituted travel bans in response to three of the variants, which may spread more quickly that previous iterations of the coronavirus. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. There is alsoemerging evidence that the South African strain may be more virulent, but the CDC has not confirmed that this is the case, and the same goes for the Brazilian one. Track the spread of the COVID-19 variants: the U.K. variant, the South African variant and the Brazilian variant. There are many circulating around the world, but health experts are primarily concerned with the emergence of … Sometimes new variants emerge and disappear. The vaccines that we're distributing now clearly can take care of that particular strain," he continued. As a virus infects people, it can mutate as it makes copies of itself. Sometimes new variants emerge and disappear. Centers for Disease Control and Prevention. Researchers are still tracking the prevalence of both, but they've found that one of the strains became dominant Columbus, Ohio, over three weeks between December and January and suspect it's likely more infectious. They want to understand whether the variants: CDC, in collaboration with other public health agencies, is monitoring the situation closely. This could mean that infected people are "actually producing more of the virus or shedding the virus at somewhat higher levels, and that might be what makes it more transmissible," he added. How many variants of the coronavirus are there? There are many circulating around the world, but health experts are primarily concerned with the emergence of three. Here's a breakdown of the concerning COVID-19 variants, including the U.K. variant, South African variant and Brazilian variant, and what to know about each: The U.K. strain, called B.1.1.7, was first reported in the U.S. in late December, and it spreads more quickly and easily than other variants, according to the Centers for Disease Control and Prevention.
