Enteric fever is caused by Salmonella Typhi and Paratyphi bacteria, with an estimated 22 million cases and 200,000 deaths annually. The highest incidence rates are in South and Southeast Asia. Multidrug resistant strains have emerged, reducing the effectiveness of commonly used antibiotics. Symptoms include sustained fever, headache, abdominal pain and rose-colored spots. Diagnosis involves culturing the bacteria from blood or stool. Treatment is with antibiotics like fluoroquinolones. Control relies on improved sanitation, water treatment, hand washing and vaccination in endemic areas.
