Nobody knows, I'd guess many months. If WFH is effective for the company, then it can last longer, or forever for some people. If the health care system collapses, then it lasts longer. If the health care system figures out a way to deal with this, then it lasts shorter. The health care system can deal with it by flattening the curve by social distancing / quarantine, building herd immunity, having a vaccine, massive testing, checking temperatures all the time everywhere, or something else. Vaccine is probably out for 18 months, but testing seems to be ramping up, so I'd guess that after several months there is going to be massive testing plus temp checks everywhere, and that stays around until herd immunity happens (which is some larger % of the population gets infected), which could be like year?
