Can you use a vacutainer needle without a safety lock on a different patient if its already been used on someone else? Also, is there a risk that the blood might clot in the needle, causing it not to work properly? What are the chances of someone getting HIV if blood is accidentally drawn with a needle that's already been used? Even if the blood is flowing out and not in, is there still a risk of HIV transmission?

I'm really worried about tuberculous lymphadenitis. Is it something that can spread from one person to another? If that's the case, could you explain how it happens? I'm just trying to understand the risks better.

Yes, tuberculous lymphadenitis is a contagious disease caused by the bacteria Mycobacterium tuberculosis. It can spread from one person to another through the air when an infected person coughs or sneezes. It is important to seek medical treatment to prevent the spread of the disease. Treatment usually involves a combination of antibiotics such as Rifampicin, Isoniazid, Pyrazinamide, and Ethambutol for several months.

I'm dealing with lymph node tuberculosis on my neck and after four months of taking medication, I noticed some pus coming out on its own, which was surprising. When I consulted with a surgeon about it, they mentioned surgery wasn't necessary. Now, I'm occasionally noticing some pus on my neck. What should I do about it?
