Findings by British medical journal The Lancet did however confirm the variant’s increased transmissibility.

The first local cases of Covid-19 with the UK

journals found no evidence that people with B117 experience worse symptoms or a greater risk of developing long Covid than those infected with different

Commenting on the first study, experts from Singapore’s National Centre for Infectious Diseases said the
were in contrast to three previous studies suggesting that B117 was deadlier than other
the Lancet study had the benefit of having used whole-genome sequencing as well as a good variety of patient and disease outcomes.
The Singapore experts, who were not involved in the research, said that while the
the results required further confirmation in larger studies.
A second study analysed self-reported data from nearly 37,000 British users of a Covid-19 symptom app who tested positive between September and December last year.
That study found that the B117
