Paratyphoid

An enteric fever caused by Salmonella Paratyphi strains A, B, and C, close relatives of the typhoid bacterium that spread through the fecal-oral route. Outbreaks trace back to contaminated water, food handled with poor hygiene, or carriers who shed the bacteria in their stool, which is why the disease clusters where sanitation is weak. After an incubation of roughly one to ten days, patients develop sustained fever, headache, abdominal discomfort, diarrhea or constipation, and sometimes a faint pink rash on the chest. While generally milder than typhoid, it can still cause serious complications without treatment. Prevention rests on safe water, thorough cooking, handwashing, and excluding infected food handlers from work until cleared, and travelers to endemic regions can reduce risk through vaccination and careful food choices.
