I'm really concerned about the different types of typhoid. Can you tell me which one is more serious, the H typhi or the O typhi? I'm worried about which one poses a bigger threat to health.

H typhi and O typhi are both serovars of the bacteria Salmonella enterica. H typhi is also known as Salmonella typhi, which causes typhoid fever in humans. O typhi is another serovar of Salmonella enterica, but it is not commonly associated with causing disease in humans. For the treatment of typhoid fever caused by Salmonella typhi (H typhi), antibiotics such as Ciprofloxacin or Azithromycin are commonly prescribed. The dosage and duration of treatment may vary depending on the severity of the infection and other factors.

I got a series of 5 rabies shots about a month back, and it was the Abhayrab brand. Recently, I got scratched by a dog again, so I decided to get 3 booster doses instead of the usual 2. I'm really anxious about whether having so many vaccines could cause any serious side effects. Could you please advise? I'm worried and need some guidance.

Nothing to worry. Trust me, it is safe.

I'm really worried and could use some advice. It's been 9 months since I had unprotected sex, and I've been tested for HIV three times, each time after 3 months. All the results have come back as "Non-Reactive." What exactly does that mean? I'm just so anxious thinking I might have HIV or AIDS. Could you please help me understand this situation?

It's okay to be concerned, but your non-reactive HIV test results at 3, 6, and 9 months are reassuring, as they indicate you are not infected with HIV. If you still feel anxious, consult a doctor for further guidance or counseling to ease your worries.
