    Covid Cases in UK: Scientists fear UK Covid cases may surge after summer lull | World News - Times of India
    LONDON: As Britain enjoyed a summer break in Covid-19 cases, the nation’s attention turned to the end of pandemic-related restrictions and sun breaks.
    But scientists warn the public not to be complacent, saying high levels of infection in the community are likely to lead to another rise in cases this fall.
    The reason for their pessimism is the delta variant of Covid-19, now prevalent throughout the United Kingdom. Vaccines are less effective than this more contagious variant, which means that Britain must achieve a much higher level of vaccination if it hopes to. to control the disease. About 60% of the British population has been fully vaccinated.
    “If you’re going to rely on vaccines, okay, then vaccinate everyone,” said Ravi Gupta, a professor at Cambridge University who did some of the groundbreaking studies on the delta variant. “But they’ve done half the vaccination work and then they’ve opened everything up. And that’s a recipe for. Things are not going well in the coming months.”
    Despite the early summer rise in Covid-19 infections, the government on July 19 removed most of the remaining restrictions on social and business interactions. Prime Minister Boris Johnson trumpeted the moment as “Freedom Day”, saying Britain’s successful vaccination program meant people were much less likely to become seriously ill or die from Covid-19.
    But after a drop in confirmed new infections after July 19, cases rose by an average of about 25,000 a day, more than 10 times higher than in early May. The seven-day average for coronavirus-related hospital admissions is about eight times higher than in May, and deaths are 15 times higher.
    All numbers remain well below their winter highs, when more than 60,000 people a day tested positive for the disease.
    Professor Julian Tang, a respiratory specialist at the University of Leicester, is concerned that infection levels in the community may actually be higher than the data suggest. “Human factors such as a drop in tests now that school is over and people avoiding exams because they do not want to miss their summer vacation – could mean new infections are being calculated and will rise rapidly in September,” Tang said.
    He believes part of the problem is the government’s reduced emphasis on social distance measures since the end of the lockdown.
    “The virus is not going to go away if you do not vaccinate everyone, including children,” Tang said. “So I think there are a lot of optimistic, overly confident messages and people get the misconception that you can go out and do everything – don’t wear your mask, go barbecue, have fun indoors. But when you want to get away from it, people do not want to do it because they have this taste of freedom and they no longer trust you. ”
    Health Minister Sajid Javid said on Tuesday that the release of the vaccine had created a “wall of defense” that “massively reduced” hospitalizations and deaths from Covid-19. The government is now considering offering reinforcements to the most vulnerable groups since early September.
    While Britain has achieved relatively high levels of vaccination compared to other countries, the downloads have not been uniform throughout society.
    The UK is initially targeting seniors and others who have been particularly vulnerable to Covid-19. As a result, over 90% of people over the age of 60 received at least one dose of the vaccine, compared with less than 65% for adults aged 18 to 35 years.
    Britain last week extended the program to 16 and 17 year olds. Government advisers are still considering whether to extend it to younger children.
    The government may be forced to act because the delta variant has reduced Britain’s chances of ever achieving “herd immunity”, the point at which many people are resistant to the disease, either by vaccination or previous exposure, to prevent it. from spreading to the population.
    Because the delta variant can infect people who have already been vaccinated, anyone who has not been vaccinated is likely to come in contact with the virus at some point, Professor Andrew Pollard, director of the Oxford Vaccine Group, told lawmakers this week. That means vaccines can slow the spread of the disease, but they can not stop it completely, he said.
    “We know very well with the coronavirus that this current variant, the delta variant, will still infect people who have been vaccinated, and that means that anyone who has not yet been vaccinated will, at some point, encounter the virus,” Pollard said.
    He said that while vaccines could “slow down the transmission process”, they could not completely stop the spread at this time.
    “I think we are in a situation here with this current variant where herd immunity is not possible because it still infects vaccinated individuals,” Pollard said. “And I suspect that what the virus will shed next is a variant that, perhaps, is even better at transmitting to vaccinated populations.”
    That means Britain needs to learn to live with Covid-19, adapting to a situation where the virus is always present, he said.
    All of this means it is not the time to celebrate Britain’s victory over Covid-19, said Gupta, a professor of clinical microbiology at the Cambridge Institute for Therapeutic Immunology and Infectious Disease.
    “We will see a resurgence in September of similar proportions to what we have just seen, if not worse. I think,” he said. “That’s why all this optimism is misplaced right now.”
