I'm really worried and curious about something I've come across. Can you explain in detail what it means if someone is S. Typhi O positive at 1:80? I've heard about these medical terms and test results, and I just want to understand what it all signifies for someone's health.

S. Typhi O positive at 1:80 in a Widal test suggests a mild or borderline immune response to Salmonella typhi, the bacteria causing typhoid fever. This may indicate a past infection or vaccination, but by itself, it doesn't confirm active typhoid; clinical symptoms and other tests are essential.

I got my Widal test results back and I'm kinda worried about them. The report says: Salmonella typhi O Antigen 180, Salmonella typhi H Antigen 180, Salmonella paratyphi AH Antigen 120, and Salmonella paratyphi Bh Antigen 120. Can you tell me if this means I have typhoid?

Based on your Widal test results, the elevated titers of Salmonella typhi O and H antigens suggest a possible typhoid fever infection. I recommend starting a course of antibiotics such as Ciprofloxacin 500mg twice daily for 7-10 days to treat the infection. Additionally, ensure adequate hydration and rest for a speedy recovery. Consult with your physician before starting any medication.

Hey, I had a question about Rabipur injections. So basically, I got 5 shots of it around 14 years ago. I'm wondering if I need to get a booster dose now, and if it's something that lasts for life. Also, how many doses are we usually supposed to get anyway? Appreciate any advice!

It provides immunity for 10yrs.But if you have doubts of exposure to dogs,then getting a booster is no harm.

I'm really worried because a rat bit me 45 days ago on my finger and I haven't gotten a rabies shot or a tetanus injection yet. Is it dangerous to start the vaccinations now after so much time has passed? Should I be concerned about any symptoms or complications?

its always better to vaccinate before 48hrs
