It has since spread across 41 countries, the WHO reported on Monday, based on 7,344 sequences that were submitted to them. JN.1 was first detected in the US in September, a month after its parent variant, BA 2.86, was recorded in the country. The Centers for Disease Control and Prevention (CDC) in the United States have named this additional mutation L455S and said it may be helping the virus to evade responses from our immune systems.Įxperiencing a COVID-19 infection or getting vaccinated typically enables the immune system’s antibodies to fight off the virus when exposed to it again. While BA 2.86 has 20 mutations in its spike proteins, JN.1 has 21. “The new variant exhibits a greater genetic divergence from its predecessors, signifying an ongoing evolution of the virus,” said Laith Abu-Raddad, professor of healthcare policy and research, at Weill Cornell Medicine in Qatar. Variants can differ in terms of their severity, contagion and response to treatments for symptoms. Additional changes or “mutations” in the DNA sequence of those spikes indicate the emergence of a new “variant” of the virus. The latter is itself part of the lineage of the “ Omicron” variant – a more severe strain of COVID-19 that peaked last year.Įach virus has its own unique “spike proteins” enabling them to infect cells and cause certain symptoms. The new coronavirus strain, JN.1, has arisen from the most recent variant before it, named BA 2.86. Here’s what there is to know about the strain and its current risk.

The new variant is now being closely monitored by public health agencies across the world due to its increased transmission rate. By mid-December, fewer than 20% of US adults had gotten the updated shot, and the CDC warned of a possible surge in serious illness if vaccination coverage fails to improve.Keep reading list of 3 items list 1 of 3 What is the mysterious pneumonia outbreak in China? list 2 of 3 The Take: Is loneliness the next global health threat? list 3 of 3 Photos: Diseases spread in Gaza amid health system collapse, Israel strikes end of list But anticipated 'high demand' did not materialize.

A new COVID vaccine strategy could help - if only people would pay attention In 2023, researchers made headway in discerning in detangling theories about what could be causing long COVID - such as lingering viral reservoirs and errant immune cells – but there are still no proven cures.
