And that's a potential concern because the spike protein from the original version of the virus is what scientists used to design all three authorized vaccines. The current VOCs all have mutations in the virus's spike protein, which acts as a key to break into cells to infect them. Right now, there are only a handful of concerning COVID-19 variants. Experts are constantly working to figure out which variants we should focus on and how they change how we combat COVID-19. Thousands of variants exist around the world, but most of them do not change the way the virus acts. Todd Ellerin, ABC News medical contributor and Director of Infectious Diseases at South Shore Health. Because there's been uncontrolled replication around the world for the last year and a half, we've created variants beyond variants," said Dr. "We're not just dealing with one virus, we're dealing with a lot of viruses. Just recently, for example, the WHO named a new variant called "mu" because it is spreading in some countries, but the CDC has not designated this variant because it is not considered a threat in the U.S. The World Health Organization (WHO) and the CDC are monitoring slightly different variants depending on whether the variant is a threat globally, or just in the United States. Simone Wildes, a board-certified infectious disease physician and public health expert at South Shore Health in Weymouth, Massachusetts. "Viruses mutate they change their form all the time," said ABC News medical contributor, Dr. That's why many new variants are being discovered in places with the highest infection rates and large numbers of unvaccinated individuals, like the United States, the United Kingdom, India and Brazil. The uncontrolled spread of SARS-CoV-2, the virus that causes COVID-19, means the virus is mutating quickly. According to the CDC, VOCs can be more contagious, more dangerous, less susceptible to available treatments or harder to detect. The Centers for Disease Control and Prevention listed the COVID-19 delta variant as one of its "variants of concern" (VOCs) on June 15.
