What is Typhoid Fever?
Typhoid fever is an illness caused by the Salmonella Typhi bacteria. It is common in areas with poor sanitation and limited access to clean water. The infection affects the intestines and bloodstream, leading to prolonged fever and other symptoms.

- Headache and body aches
- Stomach pain and loss of appetite
- Diarrhoea or constipation
- Weakness and fatigue
- Rose-coloured spots on the chest or abdomen (in some cases)
If left untreated, typhoid fever can lead to severe complications like intestinal bleeding or perforation.
How Does Typhoid Fever Spread?
The bacteria spreads through:
- Contaminated food or water: Eating food handled by an infected person or drinking unsafe water.
- Poor hygiene: Not washing hands properly after using the toilet.
- Close contact: Living with or caring for someone who has typhoid.
Who is at Risk?
- People travelling to regions where typhoid is common (South Asia, Africa, Latin America).
