The typical course of antibiotics for paratyphoid fever usually lasts 7 to 14 days, depending on the specific drug used and the severity of the infection. Most people begin to feel better within 3 to 5 days of starting effective treatment, as the fever starts to drop and other symptoms like fatigue and abdominal pain gradually improve. However, full recovery can take two to three weeks, especially if the illness was severe or treatment was delayed. It’s very important to complete the entire prescribed antibiotic course, even if symptoms disappear early, to ensure that all bacteria are eliminated and to prevent relapse or the development of antibiotic-resistant strains. After recovery, some people may still feel weak or tired for a short period, but with adequate rest, hydration, and nutrition, they generally regain full strength within a few weeks.
