I'm really worried because my father-in-law just tested positive for COVID-19. His report says "RESULTS Positive" but there's also something called "Bio Ref Interval" that shows as "Negative." Can you help me understand what that means? Is this related to a stage of COVID-19, or does it indicate something else?

The "Bio Ref Interval" being negative typically indicates that the test result falls outside the reference range for a negative result, confirming the presence of the virus. As for COVID-19, it doesn't have specific "stages," but the severity can vary from mild to severe, and it is categorized based on symptoms and clinical findings, such as mild, moderate, severe, and critical. It's important to monitor his symptoms and follow healthcare advice for appropriate management.

I'm really concerned about how quickly someone with Covid-19 can spread it to others. Like, do they start spreading the virus right after they get infected, or does it take a few days? I'm trying to figure out if there's a period where they aren't contagious. Could you shed some light on this?

they can spread immediately after you getting infected. so quarantine is done

I had sex multiple times with a sex worker and even tried oral. I'm kinda worried now, is there any chance I might have caught an STD or even HIV from this?

Yes, there's a risk of contracting STDs, including HIV, especially if protection wasn't used consistently. Oral sex carries a lower risk but isn't completely safe. It's important to get tested promptly to ensure your health and peace of mind.
