I think it is possible that we will see late term issues with a small percentage of Covid 19 patients - NOW - I have very limited facts to back up this statement, but I do have a few. As to what percentage of patients may experience this? I have no idea really, hopefully pretty small, or we would have heard more about it before now. But it may take a number of years to really know....
1 - we have been hearing these sort of concerns in numerous areas of medicine, neurology, and psychiatry from several countries already. And we are seeing some unexpected issues even in people with very minimal or non-obvious illnesses
2 - as I mentioned in a post here earlier, there is some data from a century ago about mental health issues following the 1918 pandemic. Laura Spinney stated in "Pale Rider: The Spanish Flu on 1918 and How It Changed the World" that in the 6 years after 1918 there was a 7 fold increase in psychiatric hospital admissions for a variety of diagnoses, when compared with pre-1918 admission rates - page 219 of her book
3 - In the same book, it is noted that males born in 1918, who were presenting for the draft in the USA in WWII, were almost 2mm shorter than males born in the years before or after that year - suggesting that infants in the womb displayed measureable changes in height almost 22 years later
So is it possible, even probable, that there may be long term consequences of this pandemic that we have not fully become aware just yet?? Almost certainly in my very limited understanding of what it occurring - especially since Covid 19 is a micro-vasculitis type of illness, not just a respiratory illness. It may even be affecting male testicles, since the virus is apparently found in some semen samples. Again, no one really knows what this means at this point. The urologists may have more to offer about this as time passes.
But as Laura Spinney points out in her book, we are still learning new points about the 1918 pandemic over a century later.... Hopefully it won't take us as long this time, but just consider how limited we know about how this illness is acting in most third world countries - do you really think this illness is not passing through the shanty towns in South Africa, or the smaller towns in Siberia, or the favellas in Brazil?? Will the yonomami and many other indigineous people even survive?
