A new report from Public Health England shows concerning trends, including higher transmissibility and higher cases among kids who go to school.

The Nepal variant contains the K417N mutation, which has also been found in the coronavirus strain first detected in South Africa (Beta).

Epidemiologist Professor Neil Ferguson, a member of the United Kingdom government's New and Emerging Respiratory Virus Threats Advisory Group, said the current "best estimate" was that the Delta variant could be "60% more transmissible" than the Alpha variant.

Health officials in Britain have said that Delta may also come with an increased risk of hospitalisation compared to the Alpha VoC which was first detected in Kent, England.

The latest statistics have led experts to conclude that Delta is now closing in to overtake Alpha.

The study said that the efficacy of Covid vaccines against B.1.617.2 was unknown so it carried out an initial analysis to track serological responses to vaccination.

The prevalence of COVID-19 infections in England nearly doubled in the last week of May and the estimated reproduction "R" number crept up as the "Delta" variant became more widespread, raising worries about the country's unlocking plans.

Bolton in Greater Manchester continues to be the worst affected local area, with cases rising from 795 to 2,149, while Blackburn with Darwen in Lancashire has recorded 368 new cases, bringing its total to 724.

PHE said there are "encouraging signs" that the transmission rate in Bolton has begun to fall and that the actions taken by residents and local authority teams have been successful in reducing spread.

A two-week delay to the planned easing of restrictions in England on June 21 is reportedly being considered after the number of people in the country with Covid-19 rose by 75%.

Emma Wall, UCLH Infectious Diseases consultant and senior clinical research fellow for the Legacy study, said: "Our study is created to be responsive to shifts in the pandemic so that we can quickly provide evidence on changing risk and protection".

Sutton said that it was a concern that it is not linked to other cases but the authorities are chasing primary cases to look where it might have been acquired. However, NSW, Australia's most populous state, has not reported any locally acquired cases in a month.

The World Health Organisation says it is "not aware" of any new Nepal Variant of Covid-19.

The PHE has designated the Indian, Kent, South African, and Brazilian (Gamma) variants as being "of concern". "The predominant variant now in circulation in Nepal is Delta (B.1.617.2)". The B.1.617.2 is now called "Delta".

However, the Prime Minister stressed there is no evidence that the vaccines will be less effective, saying: "We are in a different position from the last time we faced a new variant, before Christmas".

The study, from the Francis Crick Institute and the National Institute for Health Research, suggests the level of such antibodies are lower with older age and that the levels decline over time.

"Early evidence suggests there may be an increased risk of hospitalisation for Delta (VOC-21APR-02) compared to Alpha (VOC-20DEC-02) although more data is needed for us to have more confidence in that finding", the body said in its weekly variant case report on Thursday.

The study, yet to peer-reviewed, said that the Delta variant increased from 5% in February to 10% in March, before overtaking the Alpha variant in April.

"And our results suggest that the best way to do this is to quickly deliver second doses and provide boosters to those whose immunity may not be high enough against these new variants".
