Good point but once it became clear in the 80's how HIV was transmitted HIV it became almost 100% preventable just by using a condom and folks could date, work, kiss, touch each other, live a normal life, etc. without any risk of getting it and later spreading it.
Covid is a highly contagious disease and not as preventable as HIV. The younger a person is the more likely to be asymptomatic and pass it to others (clients) who are usually older then he is.
