from your wiki link, the first text on the page reads as follows:
"This article is about the disease. For the virus, see Severe acute respiratory syndrome coronavirus 2. "
your link again, re the disease Covid-19
en.wikipedia.org/wiki/Coronavirus_disease_2019
There is the virus: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), colloquially known as the coronavirus and previously known by the provisional name 2019 novel coronavirus (2019-nCoV)
en.wikipedia.org/wiki/Severe_acute_respiratory_syndrome_coronavirus_2
and there is a disease Covid-19, which is a consequence of the virus, see the first link in this post
It is a bit like the virus HIV that causes AIDS. HIV is not AIDS, alsthough AIDS at one point was referred to as "HIV disease" just as Codiv-19 is referred to as "coronavirus disease"
One of the reasons why it is so important that people understand that the virus and the disease are not the same thing is that infection with the virus does not automatically mean that a person with get the disease.
Experts on the coronavirus and Covid-19 have repeatedly stated that age and underlying health conditions are important causal factors in whether or not people who get the virus go on to get the disease.
This is still a very new virus and all the top experts are saying that all the information that they have about it is provisional. There are lots of thigs we do not know about the virus and anyone who speaks with certainty today risks looking foolish in days to come.
However, one thing that all the experts who have talked at length about causal factors have stressed is that a strong immune system appears to be important in combatting the virus and that good physical health is extremely important too.
For example, obesity in younger people is a serious risk factor.
As I said in an earlier post one expert advised everone who was not extremely physically fit to start a regime of strenuous exercise and to train hard as if getting fit enough to prepare for high risk surgery.
Another expert talked about the effect of muscle development and resistance training on the immune system. More muscles / less fat = a stronger immune system. People carrying excess weight and with poor muscle tone are likely to struggle.
If what these experts are saying is true, and it males a lot of sense to me, then it our duty to get as much exercise as possible providing we are responsible, observe social distancing, and do not engage in exercise that encourages others to put people at risk (thus me not visiting the local rivers).
We are not helpless in the face of this invisible enemy. Various experts have been advising people to get outside and engage in strenous exercise as if preparing for a fight with an opponent. That is what I am trying to do and I will carry on as long as I can.
