Here is what my Iyengar yoga teacher posted about having the coronavirus. She and her husband are in their early to mid-60’s. He works in a ski shop in one of our Colorado ski areas (epicenter of a local cluster).
Waterdog - as you are probably aware, and may want to relate to them, is that the second week of illness is when the badger virus strikes. If it's going to.
Most cases resolve, but the ones that don't have a bi-phasic progression:
No, it is not only the elderly or people who already have a medical problem who fall victim to the new coronavirus. Emergency doctor Ignace Demeyer warns about this. "We see people with a blank medical history who are very ill." It is also not just about older generations. "We have had very few older people inside so far," says Dr. Demeyer. "We now have people between the ages of 30 and 50 coming in."
"They all have the same complaints," says Dr. Demeyer. "They have been sick for a week, stayed home with the flu. The flu attack is over, they think. They feel fine for two days. And then they report with complaints of a dry cough and shortness of breath. When we then have their oxygen saturation (level of oxygen in our blood, ed.), we see that they have very low oxygen saturation for their age. "
At that time, a clear alarm goes off to the doctors that it concerns problem patients, but people do not always realize it because they do not feel very ill at the time. "They just walk in, but they are terribly affected by the virus." Emergency doctor Demeyer also shows scans of the lungs of such a corona patient. "The images we took yesterday are nothing short of terrifying."

From what I've gathered so far, somewhere around day 8 of symptom onset is where the trouble begins. Plus or minus many days of course.
At any rate, just tell here to keep on the lookout for the shortness of breath and dry cough thing. Having an O2 pulsemeter would be mighty handy as well.
