It’s considered a notable variant because it has many genetic differences from previous mutations and may cause breakthrough infections. Meanwhile, the CDC reports that BA.2.86 (Pirola), a newly designated variant of SARS-CoV-2, was detected in multiple countries.Īs of August 23, Pirola was reported in Denmark, South Africa, Israel, the United States, and the United Kingdom. The Eris COVID-19 variant has become the dominant subvariant in the United States, accounting for around 21% of circulating strains as COVID-related hospitalizations increased by nearly 19%.Īn Omicron subvariant, EG.5 first emerged in November 2021 and was recently designated as a “variant of interest” by the World Health Organization (WHO), though not yet a “variant of concern.” As of August 7, 2023, the Eris variant has been reported in 51 countries, according to the WHO. “When you do that, you prevent replication, and replication is essential for mutation.”īesides getting the vaccine, the best way to protect yourself against the new variants is to continue to follow the same precautions that protect against the original coronavirus strain: Wear a mask (consider doubling up), wash your hands, practice social distancing, avoid crowds and stay home if you can.In August, the Centers for Disease Control and Prevention (CDC) reported that EG.5, nicknamed “Eris,” has surpassed XBB1.16 (“ Arcturus“). "Getting people vaccinated as quickly and as efficiently as you possibly can will always be the best way to prevent the further evolution of any mutant,” Fauci said. The longer the virus is allowed to propagate, the more mutations will develop. Vaccine rollout is key to stopping mutationsĪnthony Fauci, M.D., director of the National Institute of Allergy and Infectious Diseases, said in a press briefing that getting the COVID-19 vaccines out quickly is important to reduce the spread of the variants while they are still somewhat rare. There is some evidence to suggest that it, too, may be able to elude antibodies. case - in Minnesota - and that person had recently traveled to Brazil, health officials said. The strain first identified in Brazil has been found in only one U.S. Vaccine makers Moderna and Pfizer-BioNTech have already announced that they are working to modify their vaccines - and possibly to create booster shots - to better protect against the South African variant.
Early studies indicate that the current COVID-19 vaccines may be less effective against that strain, although they would still provide some protection. The South African variant contains a mutation that could allow the virus to elude some of the antibodies produced through vaccines, the CDC said. Preliminary studies suggest the current COVID-19 vaccines will be effective against the B.1.1.7 strain. by March, the Centers for Disease Control and Prevention (CDC) said. It could become the dominant strain in the U.S. Studies show it is 40 to 70 percent more transmissible than the original coronavirus strain. variant, known as B.1.1.7, was first detected in September and has since spread rapidly around the world. "If suddenly a new symptom emerged or another one went away, then that would be perhaps something more concerning,” he said. He noted, however, that the differences found in the British survey are quite subtle - no new symptoms were reported by patients with the variant - and it's too early to know if they indicate anything significant.

"Variants have changes in their genetic code that will result in proteins being built differently, and those can change how the virus interacts with the body,” he said. Tony Moody, M.D., an infectious disease specialist at the Duke Human Vaccine Institute at Duke University Medical Center, said it's not surprising that a new variant would cause somewhat different symptoms. Interestingly, patients infected with the variant were significantly less likely to report a loss of the sense of taste or smell, among the more unusual symptoms of the coronavirus.
