I went to a government facility to give CB naat sputum sample. I was wearing a spec as well as a N95 Mask with additionally a pollution filter inside. So in the pic, the old man was wearing a local made mask and sneezed like typical Indian uncles aaahuu type facing towards right side. However, after filling the form with the registrar i had to go out of the room via that door, and i went along the path where he sneezed, however my mask was worn properly, i discarded the clothes, mask and took a proper shower with proper face wash and hand wash. I know i am over thinking but the risk of contracting tb(let's say i am negative), is low right? Sorry again, i am a hypochondriac so i think a lot about these things.
