So, I had this maid looking after my 1.5-year-old daughter for a few months, but she got sick once, even coughed up blood. I decided to let her go right after. This happened a couple of months back. I went ahead and got some tests done, like a sputum test for tuberculosis, which came back negative. But then she mentioned her dad passed away from TB 14 years ago. She's got a couple of sisters, a mom, and a brother in the family too. We did a digital x-ray and a helical CT chest scan, and those were normal. I'm just wondering, given her symptoms and her family history, is there still a possibility she might have active tuberculosis?
