UK Covid strain not more severe than others- The Lancet
2 studies by The Lancet say there is no evidence that the recent UK Covid-19 variant, B117, is not more severe than other strains. Despite the bit of good news, the study did say that the particular strain is more transmissible, meaning its viral load is higher and well as its reproduction rates.
The recent study, indeed, gives backing to the fact that B117 is now the dominant strain appearing across Europe. Thailand is now reporting infections featuring the strain, as a new cluster in Thong Lor district of Bangkok, is becoming Thailand’s 3rd wave epicentre.
Despite previous studies showing the strain was linked to a higher likelihood of death than the other Covid variants, the 2 new studies published in The Lancet Infectious Diseases and The Lancet Public Health journals found no evidence that people with B117 experience worse symptoms or a greater risk of developing long Covid than those infected with different variants.
Authors of the first study looked at data from 341 patients who tested positive for Covid-19. They found that 58% of those patients had B117, while 42% had non-B117 Covid-19. Of those infected with B117, 36% became severely ill or died, compared with 38% of those with non-B117, suggesting that there was no association between B117 and heightened risk of severe infection.
The study also noted that those patients who were infected with the variant were younger, and the variant occurred more often in minority groups.
A 2nd study analysed self-reported data from 36,920 British users of a Covid-19 symptom app. They found that the B117 variant had a reproduction rate 1.35 times higher than normal coronavirus variants, but also found no evidence of increased disease severity.
Thailand reported 985 new Covid infections yesterday, with the death toll remaining at 97. 28,248 have recovered from the virus, while 5, 265 are listed as still in care or under observation.
