Paratyphoid fever is a serious disease caused by Salmonella Paratyphi bacteria. The bacteria spread through contaminated food and water and person-to-person contact.
Symptoms of paratyphoid fever include high fever, weakness, stomach pain, headache, constipation or diarrhea, cough, and loss of appetite. Some people may get a rash with flat, rose-colored spots.
If a person’s symptoms go away without treatment, they may still carry the bacteria that made them sick, which can spread to others or cause the illness to return.
Without treatment, fever can last for weeks or months. Other health problems may also develop. These health problems can be very dangerous and might lead to death.
