Typhoid Fever

Typhoid fever, also referred to as enteric fever is an acute (short onset) bacterial disease. It’s highly infectious but affects humans only.

Cause

The fever is caused bacteria (Salmonella typhi bacterium), a type of bacteria commonly found in contaminated water, food and sewage. The bacteria can survive for weeks in water or dried sewage. Its incubation period is usually 1-2 weeks, and the duration of the illness is about 4 weeks.

How is Typhoid Fever spread?

It’s transmitted through

  • Contaminated water
  • Food and drinks
  • Touching mouth or utensils with contaminated hands

Note:

People may become carriers of the bacteria after the illness. Others suffer a very mild illness that goes unnoticed. They become long-term carriers of the bacteria even though they have no symptoms and could therefore be the source of new outbreaks of typhoid fever later.

What are the Symptoms of Typhoid Fever?

Symptoms usually develop 1–3 weeks after exposure, and may be mild or severe.

How Is Typhoid Fever Diagnosed?

  • Stool analysis
  • Blood analysis

How Is Typhoid Fever Treated?

Prevention

a) Hand washing

This is one of the most important aspects of prevention in domestic settings.

Following use of the toilet or as you touch people, surfaces, and objects throughout the day, you accumulate germs on your hands. In turn, you can infect yourself with these germs by touching the mouth, food or water. Washing hands frequently can, therefore, help limit the transfer of typhoid and other bacteria from hands to other places.

Steps to effective hand washing

Step 1: Wet hands and apply soap.                                               Rub palms together until soap is bubbly. Step 2: Rub each palm over the    back of the other hand
Step 3: Rub between your fingers on each hand.

 

Step 4: Rub your hands with the fingers together.
Step 5: Rub around each of your thumbs. Step 6: Rub in circles on your palms. Then rinse and dry your hands

 

Remember to wash your hands before:

  • Eating food or drinking water and beverages
