There are therapeutics for COVID. The U.S. government is not promoting them. It sounds like your husband may be too far along for them to be of much good from what I've read, but I could be wrong. There is the chance your may contract COVID too.
At any rate, you can use the internet to find such people to listen to your situation and advice. May cost $200-300 (my guess) by the time you are done. Getting the proper drugs (i.e. ivermectin) may take a little time as some of the major drug stores are not distributing what you need. For example, I just found

Of course, maybe your doctor has already done this, but many doctors are protecting their butts and not prescribing therapeutics out of fear.
Probably the best thing to do is to get everything prepared for the chance you need to take action should you get it. That's what we did... there are preventative treatments and therapeutics. They should cut down your probability of a bad outcome by 80% (or so I have read).
That being said and assuming you take me seriously (there is a lot of negative information/propaganda against what I am saying) and you can't figure it out ... send me a private message and I can speak to the Mrs. who I believe has the name of a doctor that will set up an appointment over the phone, listen to your situation and advise you as to what to do including prescribing whatever is necessary.
