What is Typhoid Fever?

Typhoid fever is a chronic bacterial infection that impacts your gut. Salmonella Typhi (S. Typhi) is the bacterium responsible for this infection. Infection by this bacterium leads to conditions such as stomach aches and high fever. Note that this fever is also known as enteric fever.

People often link paratyphoid fever with typhoid. However, remember that it is not so, as paratyphoid is caused by a different bacterium, Salmonella Paratyphi (S. Paratyphi), and its symptoms are milder.

WHO’s 2019 data shows that an estimated 90 lakh people fall sick every year due to typhoid, leading to about 1,10,000 deaths per year [1]. Read on to learn about the various causes and symptoms of typhoid fever, as well as typhoid fever diagnosis and treatment.

Typhoid Fever Causes

The human body gets infected with S. Typhi from contaminated water and food. Once it enters your body, it reaches your intestines and eventually into your blood. Then the blood carries them to your body's different organs and systems. Commonly affected body parts include the spleen, liver, gallbladder, and lymph nodes.

Individuals may also become long-term carriers of the S. Typhi bacteria, releasing them in their stools. Therefore, people in close contact with such individuals are at a high risk of typhoid fever infection.

Symptoms of Typhoid Fever

The most common symptom of typhoid is a high fever that continues for weeks if not medically intervened. If you are infected with the S. Typhi bacteria, a delay in treatment can put your health at high risk. So it is important to visit your doctor if the fever continues for more than a week and the usual medicines for the fever do not work.

Other symptoms of typhoid infection that can accompany fever are as follows:

  • Reduced or no appetite
  • Chills
  • Headache
  • Diarrhoea and vomiting
  • Rashes
  • Constipation
  • Fatigue
  • Blood in stool
  • Cough
  • Nosebleeds
  • Attention-deficit disorder

Precautions to Lower your Risk of Typhoid Fever

It’s wise to get vaccinated if your area is getting infested with typhoid disease or you are travelling to a country infested with the same. Here’s a look at the two vaccines to choose from:

Live typhoid vaccine

This vaccine is available in the form of oral capsules and is recommended for people aged six years and older. In this course, an individual must consume four capsules every alternate day as per the typhoid vaccine schedule.

If you are getting immunized for your travel plans, ensure that the last vaccination dose is taken at least a week before your journey. A booster dose is given every five years for individuals who remain at risk.

Inactivated typhoid vaccine

This typhoid vaccine is intended for anyone above the age of 2 years and is administered via injection. Taking the shot at least two weeks before your travel plans is wise. Usually, this vaccine consists of a single dose. However, if you have a serious reaction after your first dose, it is wise to consult a healthcare professional to get another shot. A booster dose is given every two years for individuals who remain at risk.

Typhoid Fever Diagnosis

Doctors will assess your symptoms and travel history and recommend a few lab tests if they suspect typhoid. You may need to get the samples of your blood, urine, stool, bone marrow, and skin checked as part of this process. Treatment is initiated if the results show the presence of the S. Typhi bacteria.
