What Causes Persistent Fever And Viral Infection?

Question: Hello, I live in a country in East XXXXXXX where Malaria and typhoid is common. On monday I started having a feeling of being sick. I ended up having a high temperature during the evening time and went to the hospital where I was given an injection of Paracetomol. My temperature went from about 38.5 to 37.5 degrees celsius and they sent me home, but I still didn't feel all that great when leaving. Later that night when going to sleep my temperature went back up a lot I think to like 39.5 and I felt terrible headache, shivering, no appetite, and felt like vomiting at one point (i didn't). I went back to the hospital and this time they did bloodwork and told me that I had typhoid. They gave me an injection of Ciprofloxacin which dropped my temperature a lot and I felt better. They then gave me ibuprophen, paracetomol, and the Ciprofloxacin all in tablet form for me to take. On Tuesday I took the paracetomol and ibuprophen every 6 hours as instructed and also took the antibiotic after 12 hours as instructed. I felt pretty good for most of that day (Tuesday) but when I went to sleep at night my temperature started flaring up badly all the way to 39.5 degrees celsius again with same symptoms from the first night. I went to a different hospital this time and the doctors there did more blood work and also said I have typhoid based on the blood work. They gave me a paracetomol injection that brought my temperature down to 37.5 but then it went back to 38.2 within an hour. Later on around 9am a different doctor reported to work and said he didn't think it was typhoid and instead thought it was a viral infection. I have given them a stool sample to test but no results yet. They said I had to be admitted to the hospital because of my symptoms and persistent fever. My fever got back up to 39 and they gave me more paracetomol after 6 hours and the temperature went to 37.9 for now and then back to 38.1. All tests thus far have said it's not malaria.
