Typhoid fever

Typhoid fever is a bacterial infection caused by Salmonella Typhi. Prevalence: Common in regions with poor sanitation and limited access to clean water, such as parts of Africa and South Asia.

• Contaminated food and water: Ingestion of contaminated food or water is the primary mode of transmission.
• Person-to-person contact: Close contact with an infected individual can also spread the bacteria.

• High fever
• Headache
• Stomach pain
• Constipation or diarrhea

• Antibiotics: Prompt antibiotic treatment is crucial for recovery.

• Potentially life-threatening: Without treatment, typhoid fever can lead to serious complications and death.

• Vaccines: Typhoid vaccines can provide some protection.
• Safe water and sanitation: Access to clean water and proper sanitation is essential for prevention.
