I'm looking at my widal test results and I'm a bit worried. The values are showing Salmonella Typhi O Antigen at 140 and Salmonella Typhi H Antigen also at 140. Salmonella Paratyphi AH and BH Antigens are both at 120. Does this mean the test is negative? And if so, does that rule out typhoid completely or is there still a chance it could develop later?

I'm really worried right now. I had a one-time encounter with an escort and we used a condom. I'm super concerned about my chances of getting HIV from this. Can you give me some insight on that? Also, Id really appreciate it if you could recommend which STD tests I should consider getting. I'm pretty anxious about this whole situation.

I'm dealing with an abscess in my underarm and some mild back pain, and I just found out my Mantoux test came back positive with an ESR of 30. Could this mean I have spinal tuberculosis? And if it is, are the medications they give out at district health centers for spinal and lung tuberculosis the same? I'm pretty worried about what all this means.

Surgeon opinion is advised to the patient.
