Typhoid fever, a bacterial infection caused by Salmonella Typhi, remains a concern in regions with limited sanitation and access to clean water. Despite advances in medical science, typhoid continues to affect millions, making it essential to understand its symptoms, causes, and the myths surrounding it.

Typhoid fever is usually spread by contaminated food and water. The bacteria invade the intestinal wall and may spread to the bloodstream, leading to symptoms that range from mild to severe. If left untreated, typhoid can be life-threatening. Early detection and treatment are crucial for a full recovery.

Common Symptoms Of Typhoid Fever

The symptoms of typhoid fever develop 1-2 weeks after exposure. Some early and advanced symptoms include:

Early Symptoms of Typhoid Fever

Early symptoms of typhoid fever are often non-specific and can be mistaken for other illnesses. They include:

Fever: The most common early sign, usually rising in the afternoon or evening.
Headache: Persistent and often severe headache.
Muscle Aches: Generalized body pain and discomfort.
Loss of Appetite: A significant reduction in the desire to eat.
Fatigue: Unusual tiredness and weakness.

Diagnosing typhoid fever involves:

Medical history and physical Exam: Reviewing symptoms and potential exposure.
