What is Typhoid fever?

Typhoid fever is an infection caused by a bacteria called Salmonella Typhi Download the apartment floor plan. It spreads easily through food and water contaminated by sewerage. You can also get it from someone who has the infection. The infection is quite common in areas with overcrowding & poor sanitation.

How do you get typhoid fever?

Typhoid is spread through the faecal-oral route. This means that the bacteria are found in the faeces (stool) of an infected person. You can get the infection from water, food or other objects that have been contaminated with the infected stool. If you eat/drink contaminated items or touch contaminated surfaces you will get the infection.

What are the symptoms?

Unless it’s treated, you can get these symptoms over a few weeks:

  • Constipation or diarrhoea

  • Rash

Week 2:

  • Fever that stays high
  • A swollen stomach
  • Very bad constipation or diarrhoea
  • Weight loss

Week 3:

Week 4:

People who recover from Typhoid can still carry the bacteria in their system, without being sick. The bacteria still spreads through their faeces, infecting others.
