If one has a viral infection of some other sort, are you less likely to get Covid19? In other words, If your blood and antiobodies (what ever they are called) are on heat dealing with another virus, does it make your system a less attractive proposition for Covid19?

Some parts of our immune system are very generic, and may provide some cross-protection between different pathogens.
- For example, our cells produce interferon when infected by any virus, warning nearby cells to be ready to ward off an infection.
- So if your body has been infected by a different virus (say, the common cold), your cells will already be producing interferon, and that might give your body a 1-day head start when exposed to the coronavirus.

Some parts of our immune system are very narrowly targeted at a particular pathogen.
- Immunoglobulins recognize particular proteins on the surface of a pathogen, and don't respond to different pathogens
- So you won't get any protection against coronavirus if you are infected by the common cold
- This system is used by immunization: By exposing your body to samples of the protein on a particular pathogen, your immune system is prepared and is ready to react quickly when exposed to that particular pathogen in future.

Is there any evidence that patients receiving antiviral medication to keep HIV at bay fair any better when challenged with COVID-19

Doctors says that people with other diseases are more likely to have COVID. Their immune system is weak and it’s the best environment for viruses. Make sure your current virus was diagnosed correctly. Otherwise it may influence the whole treatment process. The worst thing is fighting with some virus that you don’t have because in fact you have another one. Get well soon!

I'm not saying its true as I know very little on the subject but I was watching a program the other day and some virologist said its possible that those walking around showing no symptoms may have previously caught a virus that was closely related to Covid 19

Several anti-viral drugs were trialed against SARS-COV2.

Remdesivir (originally developed as a Hepatitis-C treatment) is one that seems to show some effect against COVID-19, and has been given emergency-use authorisation for severely ill patients.

Remdesivir was one of the cocktail of drugs that were recently given to Donald Trump.

On May 26, the US Food and Drug Administration (FDA) has granted an Emergency Use Authorization (EUA) to GlaxoSmithKline (GSK) and Vir Biotechnology's sotrovimab (VIR-7831) to treat mild-to-moderate COVID-19 for adult and paediatric COVID-19 patients aged 12 years or above, who are at increased risk for progressing to severe disease, including hospitalisation or death.
