Cases of the highly transmissible Covid-19 delta variant nearly doubled in one week across the UK, from 33,630 cases last week to 75,953 cases today, with more people hospitalized.
Bloomberg reports that about 90 per cent of cases sequenced and genotyped across the UK are the Delta variant. The total of one Thursday day is the highest since February 19, when 12,027 cases were registered in the country.
Through it all, Public Health England (PHE) still understands the fact that even when the vaccine program has reached all adults, it is still possible to obtain COVID-19, presenting a challenge to the government in trying to reopen it. lo. the economy.
“We aim to live with this virus as we do with the flu,” Health Secretary Matt Hancock said this week.
The increase in cases occurs mainly in younger age groups
As the Delta strain is behind the recent rise in cases in the UK, especially among younger age groups, two new studies shed some light on what is happening.
In the first study, according to the Center for Infectious Diseases Policies and Diseases (CIDRAP), it was discovered that young people contribute to drive the exponential growth of COVID-19 cases in England.
The second study showed a reduction in the efficacy of the COVID-19 vaccine and antibodies against the more transmissible Delta variant.
This increase in cases among the younger generation is to be expected, simply because at the beginning of the vaccination push, the first doses were given to the elderly and those at higher risk.
This was demonstrated by researchers who found that those 65 years or older who had been vaccinated at first still had a lower association between infections and hospital admissions.
“We can have a lot of comfort in the fact that there seems to be very good protection in older age groups, where virtually everyone has been doubly vaccinated,” said lead study author Paul Elliott, MBBS, PhD, director of the React program. , he said in a BMJ Press release today.
The authors said that the actual number of SARS-CoV-2 variants has probably been underestimated and that more worrying variants will continue to appear, making it even more important to be vaccinated.
