Covid19 Becoming a 'Silver surfer's ' Disease in England?

Imperial College London's React 1 study is based on 100,000 swabs sent to English homes (https://www.theguardian.com/world/2022/mar/10/uk-covid-cases-rising-among-those-aged-55-and-over). Overall levels of Covid infections are continuing to fall in England. In deed, the React 1 study found that the R This value (a measure of how many people are infected by one individual who has the disease) is below 1, in people who are 54 years of age and under. Perhaps surprisingly, the R value for people who are 55 and older was 1.04. means that Covid19 infections are increasing in this cohort. The people running the study, suggest the increase in older folk is probably due to a combination of factors. The latest Omicron variant is more infective and there has been a marked increase in socialisation by people in England, post 'freedom day'. It is also likely that viral immunity has waned to a greater degree in older folk. In the UK, older people received their vaccinations, including the 'booster' dose, much earlier. This gives more time for a response decline. It's also true that immune systems deteriorate with age. It looks as if Covid19 is fast becoming an old person's disease in England. The prognosis for 'silver surfers', contracting this viral infection, is also worse.
