Rise in UK Coronavirus cases stoke concerns over 3rd wave

The number of new Coronavirus infections in the UK hit a near two-month high Friday as British regulators authorised the use of the single-dose vaccine from Johnson & Johnson.

The latest authorisation, which takes the number of vaccines in the UK's armoury to four, comes amid growing speculation that the new variant of the virus first identified in India may prompt the British government to delay its next planned easing of lockdown restrictions in England.

Government figures showed that another 4,182 new confirmed cases were reported across the UK, the highest daily figure since April 1. The cases bring the total number of confirmed infections reported over the past seven days to 20,765, a 24% increase from the previous week. The rise prompted scientists to say the UK is now in the midst of a third wave of the pandemic.

The number of cases remains well below the daily high of nearly 70,000 recorded in mid-January, during the peak of the second wave, but but the upward trend has raised questions about the UK government's plan to lift all remaining social restrictions on June 21. The government, which has lifted restrictions in stages and allowed pubs and restaurants to resume indoor service last week, has said it will make a decision on the next planned easing on June 14.

The variant identified in India is believed to be responsible for up to 75% of new cases in the UK and more transmissible than the previously dominant strain of the virus.

Critics argue that the Conservative government is to blame for the variant's seeding in the UK. They say officials acted too slowly to impose the strictest quarantine requirements on everyone arriving from India, which is in the midst of a catastrophic resurgence of the virus.

Many scientists say the increase in cases is no surprise but that the rapid rollout of vaccines will provide a firewall in a country that has seen Europe's highest virus-related death toll at more than 127,500. While the most vulnerable people should have vaccine protection, there are worries the virus could spread widely among younger adults.

As of Friday, 58% of the British population has received at least one vaccine dose and around 35% have gotten two shots. The UK vaccination programme started with the oldest age groups and aims to have offered a jab to all adults by the end of July.

It seems almost certain that we will face a third episode of rising COVID-19 infections," said James Naismith, a professor of structural biology at the University of Oxford. It seems likely that the Indian variant will mostly confine itself to the unvaccinated younger population. It is much less likely to cause serious disease in this group. However, less likely is not the same as zero. With large enough numbers of infections, appreciable numbers will get seriously ill.
