Paratyphoid fever presents with a range of symptoms that typically develop within 6 to 30 days after exposure, most often appearing within one to two weeks. The illness usually begins gradually with a persistent fever, which may be accompanied by headache, fatigue, weakness, and a general feeling of malaise. As the infection progresses, patients often experience loss of appetite, abdominal discomfort or pain, and disturbances in bowel habits such as constipation or diarrhea. In some cases, small rose-colored spots may appear on the chest or abdomen—these are characteristic but not always present. The spleen and liver may become enlarged as the body attempts to fight the infection. The overall intensity of symptoms can vary depending on the person’s age, immune status, and bacterial load, but without treatment, the fever can last for several weeks and may lead to complications. Early diagnosis and prompt antibiotic treatment are crucial for recovery and to prevent transmission to others.
