Typhoid fever is a bacterial infection that can spread throughout the body, affecting multiple organs, and if left untreated, may lead to severe complications or death.
It is caused by the bacterium Salmonella typhi, which is related to the bacteria responsible for salmonella food poisoning.
The infection is highly contagious, with infected individuals excreting the bacteria through their stool, and occasionally through urine.
When someone consumes food or water contaminated with even a small amount of this infected waste, they can contract the bacteria and develop typhoid fever.
Who’s at Risk?
Typhoid fever is most common in regions with poor sanitation and limited access to clean water. Children are particularly vulnerable to the disease, likely due to their developing immune systems. However, children often experience milder symptoms compared to adults.
Symptoms of Typhoid Fever
Key symptoms of typhoid fever include:
- A persistent high fever that gradually increases each day
- Headaches
- General body aches and discomfort
- Extreme fatigue
- Cough
- Constipation
As the infection progresses, symptoms may become more severe, such as loss of appetite, nausea, abdominal pain, and diarrhea. A rash may also develop in some cases.
Without treatment, these symptoms can worsen over several weeks, increasing the risk of serious, life-threatening complications.
