A highly significant Covid variant, currently referred to as BA.X, is now being officially monitored by the World Health Organization (WHO). This particular variant, which has yet to be officially named, has been categorized as a “currently circulating variant under monitoring” by the WHO. Although only three cases have been detected worldwide, health officials are concerned about its numerous mutations. Denmark and Israel are the only countries to have reported cases so far.
Although the BA.X variant has not been detected in the UK yet, there are fears among some scientists that it could cause a significant increase in cases. These scientists have called for the reintroduction of face masks to slow down the spread of the variant. The UK Health Security Agency has reported a rise in the prevalence of another variant, EG.5.1, which accounted for 25.7% of sequenced cases in England. However, experts believe that this variant is not more dangerous than other circulating strains.
The BA.X variant first attracted attention after two cases were identified in Denmark and shortly after in Israel. Virologists have confirmed that all three cases are the same virus due to the shared collection of mutations. The BA.X variant has more than 30 mutations in its spike protein, which plays a crucial role in infecting human cells. These mutations could potentially help the virus evade the immune system.
While it remains unclear whether the BA.X variant will spread efficiently or fizzle out like other heavily mutated variants, it is being closely monitored due to its significant number of mutations. Surveillance and sequencing are crucial for detecting and tracking new variants, according to Dr. Maria Van Kerkhove, lead for the Covid response at the WHO.
Professor Paul Hunter, an infectious disease specialist, has suggested that the BA.X variant could already be present in the UK or the US if it is more contagious than existing variants. Some scientists have called for the reintroduction of face coverings to slow down the spread of the variant. However, others caution against panicking and argue that pandemic-era restrictions may not be necessary.
Despite the rise in Covid cases, the UK government has stated that it will not reintroduce pandemic-era measures unless a highly concerning variant emerges. An autumn booster vaccination campaign is set to begin soon, targeting older age groups, care home residents, and frontline NHS staff. The efficacy of vaccines in reducing hospital admissions is evident, with data showing that individuals who received the vaccine last year were around 53% less likely to be hospitalized with Covid.
In summary, the BA.X variant is a significant Covid strain currently under monitoring by the WHO. Although its potential impact is still unclear, experts are closely monitoring its mutations. While some scientists have called for stricter measures to slow down its spread, others believe it may not necessitate pandemic-era restrictions. The government continues to promote vaccinations as a vital tool in combating the virus.
