Typhoid Fever - #16994

Last month, my younger brother had typhoid fever and it was a horrible experience for all of us. It started with a mild fever that would come and go, and we thought it was just seasonal flu. But after a few days, his fever shot up to 103°F and wouldn’t go down even after taking regular fever medicines. He also complained about constant headaches, stomach pain, and weakness like he had no energy to even sit up properly. We rushed him to the doctor, and they did a blood test which confirmed it was typhoid fever. The doctor prescribed antibiotics, and we were told to give him only light food like khichdi and coconut water. It took almost two weeks for him to recover, but even now, he still looks weak and complains about digestion issues. He gets bloated easily and says he doesn’t feel hungry like before. I started reading about typhoid fever in Ayurveda, and I came across terms like Jwara and Agni imbalance. I also read that certain herbs like giloy, tulsi, and neem might be useful in recovery. I want to know, how does Ayurveda explain typhoid fever? Is it considered a Pitta-related issue, and how does it affect digestion and immunity? Also, is there a way to prevent typhoid fever naturally through Ayurveda? We live in a place where the water quality isn’t always great, so I want to know if there are any Ayurvedic methods to purify drinking water or boost immunity against such infections. Right now, my brother is still feeling weak even though he is eating more than before. What Ayurvedic remedies or foods can help him regain his strength and get back to his normal routine? Should he continue drinking herbal kadha, or are there specific Ayurvedic medicines that help in post-typhoid recovery? Would really appreciate some advice on how to manage typhoid fever and also how to recover fully after it.
