The UK Health Security Agency (UKHSA) has confirmed the presence of a highly mutated Covid variant, referred to as BA.X or BA.2.86, in the country. Although the exact number of cases has not been disclosed, one patient infected locally has been hospitalized in London. This announcement comes shortly after the World Health Organization (WHO) declared the variant as a “currently circulating variant under monitoring.” The UKHSA is working to assess the situation and provide further information. Samples of the variant have been sent to the School of Immunology & Microbial Sciences at King’s College London for analysis.
Dr. Luke Blagdon Snell, an infectious diseases and microbiology specialist, reported the hospitalization of a patient at Guys and St Thomas’ Hospital in London with the highly mutated strain. Dr. Duncan Robertson, an academic specializing in policy and strategy analytics, confirmed that BA.2.86 has been detected in England. The severity and transmission of the variant are being investigated, and vaccination eligibility may be reviewed depending on the findings.
The variant first appeared in Denmark before being detected in Israel and the United States. Some scientists have expressed concerns and suggested the reintroduction of face masks, while others believe it is premature to panic and do not anticipate the need for lockdown restrictions. The spike protein of the BA.X variant, which is targeted by vaccines, has over 30 mutations, including some that could potentially help the virus evade the immune system.
Dr. Simon Clarke, a microbiologist, highlighted the significance of the variant and its potential impact on the virus’s behavior. However, he also emphasized that with the knowledge gained so far about Covid-19, a swift response can be mounted if necessary. Other experts, including Professor Francois Balloux from University College London, described BA.2.86 as the most remarkable SARS-CoV-2 strain since the emergence of Omicron, suggesting that it may have been circulating for months.
Currently, there is limited information available on BA.2.86, and further surveillance and sequencing are necessary to closely monitor its development. Although the variant has been identified in the UK, its potential implications and transmission patterns are still being determined. It is crucial to remain vigilant and continue implementing measures such as surveillance and sequencing to identify new variants and track known ones.
