I'm really concerned about my husband. He tested positive for COVID-19 back on May 17, 2021, and it's been over three months since then. On May 24th, a CT scan showed he had 25% lung involvement. He was on oxygen support for a month and got discharged on June 22, 2021, so it's been about two and a half months now. His oxygen level is around 98-99 when he's just sitting, but when he does brisk walking or climbs stairs quickly, his breathing gets faster for a couple of minutes, and then settles back down. During this time, his oxygen saturation levels drop to about 89-93 for a few seconds before going back up to 99 and staying there. Is this something we should be worried about? Also, he sometimes gets a dry cough a few times a day and feels a mild chest pain then. His respiratory rate is around 20-22 bpm. Are these symptoms normal or is there something we should be looking into? I'm really anxious about all this.

I'm worried that I might have caught TB from a friend who's being treated for it, but I don't have any symptoms yet. I'm trying to figure out which test would be most accurate to detect latent TB. Can the Mantoux test and sputum AFB both find it, or is one better than the other?

The most accurate test for detecting latent TB is the Interferon-Gamma Release Assay (IGRA), such as QuantiFERON or T-SPOT.TB, which measures the immune response to TB proteins; the Mantoux test (Tuberculin Skin Test) is also used, but it has some limitations, such as cross-reactivity with BCG vaccine and false negatives in immunocompromised individuals; sputum AFB (Acid-Fast Bacillus) smear is used to diagnose active TB, not latent TB, so it's not relevant in your case;

Oxygen levels are fluctuating between 90 and 94. I'm really worried because the reports came back negative, but the CT scan shows positive for COVID-19. The hospital isn't allocating a bed. What should I do?

I've been on meds for pulmonary tuberculosis since January 2nd, but I stopped taking them on June 28th without checking in with my doctor. After about ten days, I started them again. Now, I've got some serious chest and stomach pain. Could this be because of how I stopped and started the meds? What should I do?

donot stop tuberculosis medicines, consult your pulmonologist for further treatment process
