The lack of interest may well be that the US is in its summer season and not many people have a respiratory illness. Here in Melbourne it seems like every second person has a cough. I pick up food deliveries from 40 restaurants a day and deliver to 40 households. On average 2 people message me each day to leave the delivery at the door because they have covid-19. My mum and dad both in their 80s are currently self isolating at home. They both took rat tests and both came up positive. My wife has her second cough/cold for the winter and has taken two rat tests both negative. That's just a small sample from my small world.
Each to their own when it comes to buying or selling but I want to be holding as many shares as I can in rap the day the instant covid-19 test hits the international market.
