The world is watching a new Covid variant, NB. 1. 8. 1, which has started to spread across the globe. This variant has already reached the U. S. and is being closely monitored by the World Health Organization. The concern is that NB. 1. 8. 1 might be more contagious than the current dominant strain, LP. 8. 1. This could lead to a rise in Covid cases during the summer months. However, there is some good news. So far, NB. 1. 8. 1 does not seem to cause more severe illness than other variants. It also does not appear to be better at evading protection from vaccines or previous infections.

The U. S. has not seen a significant Covid wave in a while. This, combined with the fact that fewer than a quarter of adults have received the latest booster, could mean that population immunity has decreased. This could potentially lead to a small surge in infections. Experts are keeping a close eye on the situation. They are monitoring Covid strains to understand how the virus is changing and to inform updates to vaccines.

The variant has been detected in several states, including Arizona, Rhode Island, and Ohio. It is already the dominant strain in China, where it has spread rapidly since the start of the year. Meanwhile, the previous dominant strain, LP. 8. 1, has become less common. A recent study suggests that NB. 1. 8. 1 has the potential to become the dominant variant due to additional mutations that could make it more transmissible.

Doctors are advising people who have not been vaccinated or have not had Covid in a while to get a booster if they are eligible. The current booster targets a cousin of NB. 1. 8. 1, so it should provide some protection. The FDA has asked drugmakers to update Covid vaccines to target the LP. 8. 1 variant this fall. However, the approval of updated Covid shots may be limited to older adults and younger people with medical conditions. This has raised concerns about the vulnerability of pregnant people and children under 5 to severe outcomes from Covid.

Experts are also worried that even healthy adults who have been vaccinated before might not have optimal protection. Immunity from vaccines can decrease over time, and the virus continues to evolve. This means that staying up-to-date with boosters is crucial. It is important to remember that while the new variant is a concern, it is not causing more severe illness. Staying informed and taking necessary precautions can help manage the risks associated with NB. 1. 8. 1.
