In other news:
1.There is increasing doubt about how long lasting immunity will be to Covid.
Immunity to Covid could be lost in months:
https://www.msn.com/en-gb/news/uknews/immunity-to-covid-1... 2. Hopes had been that immunity would last for at least several years, as was true of SARS, and that it would not be like OC43 or 229E, two other coronaviruses that cause "colds", where you could be re-infected as soon as 4 months after recovery. COVID may end up being only a four month immunity, however, as we are seeing cases where people are re-infected four months later:
https://www.vox.com/2020/7/12/21321653/getting-covid-19-t... This is a single case, so it may be something unique. Note that we would not be seeing very many of these cases just yet because for it happens, you need a patient who was infected very early, and who recovered very early, and then who also got re-exposed four months later. There were perhaps only 1000 patients worldwide who had recovered by the end of February.
3. In a study of patients who had Covid and recovered, and who then later had an echocardiography done, lasting heart damage was found in about 50% of the patients:
https://academic.oup.com/ehjcimaging/article/doi/10.1093/... In patients who only had mild symptoms, there were 215 in the sample, of whom 98 had abnormalities detected, so 45% percent of the patients will "mild" symptoms had lasting effects on their heart.
4. Even patients that show no symptoms at all may have lung damage, though it is probably reversible:
https://www.npr.org/sections/goatsandsoda/2020/06/23/8645... In a study published in Nature, 57% of the Asymptomatic people who had a CT scan done showed "striped shadows" or "ground-glass opacities", clear signs of inflammation in the lungs.
[Quote=Dr. Alvin Ing, a professor of respiratory medicine at Macquarie University]To find so many asymptomatic patients with such significant changes on CTs is quite surprising. The symptoms underestimate the severity of the disease.[/OUTER_QUOTE]
So, taken together, these mean football is less likely this fall. If there is no immunity, it will be very hard to re-open enough to have football. If there is lasting damage to hearts and lungs even in mild cases, I just don't see them risking playing.
