My wife presented with symptoms quite similar to covid-19 to A&E (UK: A&E ~= ER) after a cruise we went on in late November. She has never smoked but she did get quite breathless and shook it off after about a week. As you say, there are a lot of anecdotes.

A decent antibody test would be nice but at the moment we don't know enough about how the bloody thing works. Even if you have detectable antibodies after an infection, does that mean you have any immunity to another infection and if so, for how long?

My money is on this thing turning into another 'flu after about five years. It will stop killing large numbers of people and evolve into a sort of status quo, just like the seasonal 'flus. It will still be a killer but not quite so aggressive as it is now. It is not as aggressive a killer as Ebola but it spreads far easier. Evolution will ensure that it will find a "happy" medium where it can carry on spreading but we don't still feel the need to eradicate it because we can live with the consequences of the adjusted version.

My language in the above para is a bit off but the sentiment is the same. We happily jump into cars every day (not so much now) and kill ourselves and others in pretty large numbers across the world but that is judged an acceptable risk. covid-19 will simply become another one eventually. For now, it is a right old shit show and we do not understand the enemy at all well. We do not know how to live with it.

We will.
