The clinical manifestations of typhoid fever need to be differentiated according to the development of the disease.

Typhoid fever is a disease that people are easily infected in daily life. Generally speaking, after contracting typhoid fever, the patient's body will show the following symptoms.

1. Initial stage

This is equivalent to the first week of the disease. The onset is usually slow, with fever being the earliest symptom, often accompanied by general discomfort, fatigue, loss of appetite, sore throat and cough. The condition gradually worsens, and the body temperature rises in a step-like manner, reaching 39-40°C within 5-7 days. There may be chills before the fever, but less chills, and there is no obvious sweating when the fever subsides.

2. Extreme period

This corresponds to the 2nd to 3rd week of the disease, and there are often typical symptoms of typhoid fever, which helps with diagnosis.

3. Remission period

This is equivalent to the 3rd to 4th week of the disease. The human body's resistance to Salmonella typhi gradually increases, body temperature fluctuates and begins to decline, appetite gradually improves, abdominal distension gradually disappears, and spleen enlargement begins to shrink. However, there is a risk of intestinal bleeding or intestinal perforation during this period, so you need to be particularly vigilant.

4. Recovery period

Starting from the 4th week of the illness, body temperature returns to normal and appetite improves, and patients usually recover completely in about a month.
