The DELTA variant of the coronavirus (also known as the Indian variant) is more contagious than the mutations that have spread so far-also from the alpha type (the previous British variant).According to data analysis by the UK Health Service (PHE), the risk of infection for family members is estimated to be 60% higher, writes German wave.
This increases the risk for people who have only received the coronavirus vaccine once before. Laboratory tests have shown that these viruses multiply faster in the body.
For the upcoming summer weeks, it’s important to know: Karl Lauterbach, a politician of the German Health Social Democratic Party, cites research from the University of Oxford to tell the RBB Public Service that the delta variant is more seasonal than originally thought. It’s much more obvious. This means that the risk of infection in summer is much lower.
The delta variant is also considered risky because the symptoms it causes are clearly different from previously known variants of coronavirus. Affected people will complain of headaches, runny nose and sore throat.
Temperature is also present in this variant, but there is no loss of smell and taste, as noted in the report of infected people through the UK app to monitor symptoms of the coronavirus.
Tim Spector of King’s College London analyzed the results of this study and said that this means that covid-19 is more often seen as a cold among young people.
The delta variant spreads very fast. This has been proven in the UK, where approximately 58% of adults have received the two doses of vaccine required for complete protection. “Currently, it is increasing by about 50% every week,” Sandra Ciesek said. “This is of course a warning sign,” explains the director of the Institute of Medical Virology at the University Clinic of Frankfurt am Main.
The 7-day incidence rate in the UK fell below 20 in early May and has now risen again within 7 days to more than 70 new infections per 100,000 residents. This is why British Prime Minister Boris Johnson has postponed the cancellation of all measures originally scheduled to spread in England on June 21 for four weeks.
According to the data analysis of PHE in the UK, people who are fully vaccinated with BioNTech or AstraZenec can be well protected from the serious flow of disease. As pointed out, the efficiency is about as high as the alpha variant. Compared with unvaccinated people, the risk of hospitalization is reduced by more than 90%.
Those who received only one dose of the vaccine received significantly less protection. The analysis shows that, especially the AstraZeneca vaccine, it protects well in other aspects, and the protective effect is significantly reduced after the first vaccination.
