LONDON: Delta variant mutations from Covid-19, are classified in the UK as a variant in investigation (VUI) amid fears of increasing its transmission, it is less likely to display any symptoms, a new real-world study word on Thursday.
The latest results from the long-term real time assessment of community transmission [reaction-1] show the prevalence of Delta AY.4.2 variant has grown at a rate of 2.8 percent a day since September and riding several levels of English high infection.
Analysis by the Imperial College London and Ipsos Mori are based on swab tests taken at home by more than 100,000 people in the UK between October 19 and November 5.
It was found that people who were infected AY.4.2 tended to have “symptoms of loss or change of flavor or odor, fever or new persistent cough and also tend to have other types of symptoms.
“Why is we more contagious we don’t know.
It seems lacking symptoms, “said Professor Paul Elliott, director of the program reacted from the Imperial Public Health School.
Data shows that only 33 percent of those who have mutations have this classical symptom, compared to 46 percent of those who have deltas.
Overall, this research found that infections in the UK have fallen but are still very high, and now at the same level until January this year.
“Although hospitalization and death remain lower than the previous peak, data shows that infection throughout the country remains very high,” Professor’s record Elliott.
“The prevalence level continues to decline throughout this round, but the total number of 1.57 percent is almost double higher than the previous round.
It is possible that the prevalence level can rise once again now the children have it back to school after half the term, even though this is at least partially offset by as many people who have Jab Booster when offered and those who are twelve years old or more than have vaccines, ” said Elliott.
The study also sees the effectiveness of the booster dose to prevent infection, find that the risk of infection is around three times lower in those who have received the third dose, compared to those who have received two.
For those who are 50 years and above, have a dose Third reduce the risk of infection about half compared to two doses.
“This reaction room provides another reminder of the effectiveness of the vaccine against Covid-19.
When we approach the winter, it is very important that everyone who meets the requirements to appear for their jab – whether it was their first dose, the two Dr.
Jenny Harries, chief executive of the British Health Security Agency (UKHSA).
“Remember that anyone who is over 12 years old can now receive their first Jab, and Booster will be offered to everyone more than 40 years.
Please do that offer to make sure your immunity is not reduced,” he said.
Seeing the trend in the latest study period, infection fell from a very high level during October.
However, there is a wide variation in the data at the end of the test period, meaning it is not clear whether the infection continues the trend to decline this month.
“What we can see very clearly is that since the launch of Covid-19 vaccination, the mortality rate remains relative to the prevalence of infection, indicating its effectiveness in preventing infection causing people to become severe and death,” said Professor Christl Donnelly, “Professor of statistics epidemiology In Imperial and Professor of Applied Statistics at Oxford University.
Kelly Beaver, Ipsos Mori CEO, added: “The high prevalence found in this reaction round reminds us of all the importance of the residual alert, while data on the Jabs Booster is an important reminder for everyone to get Their jab booster when available to them to ensure the best protection against Covid-19.
