I caught covid back on April 6th and ended up in the hospital for a couple of weeksspent about 4 days in the ICU with some oxygen support, steroids, and remdesivir. They let me go on April 22nd. But here's the thing, I just went to this lab for an MRI and a CT scan to check for any black fungal infection. There were covid patients around, and one went into the CT scan room right before me. I had to take off my N95 mask for the scan, and now I'm freaking out a bit about possibly getting re-infected. Should I be worried about this?
