What Is Typhoid Fever? Unmasking the Hidden Danger

Typhoid fever is a serious bacterial infection caused by Salmonella enterica⁽¹⁾. Closely related to this is paratyphoid fever, an illness caused by a different strain of Salmonella enterica⁽¹⁾. While both infections share similar symptoms and risks, they require the same level of vigilance, particularly when traveling to high-risk areas⁽¹⁾.

The danger of typhoid fever lies in its stealth. It thrives in regions where sanitation and clean water access are limited⁽¹⁾. Travelers should be especially cautious in parts of Asia—such as South and Southeast Asia (e.g., Thailand, Vietnam, Cambodia, Laos, and India)—Latin America (e.g., Mexico), and Africa⁽¹⁾. These areas pose a higher risk due to possible contaminated water sources and inadequate hygiene practices.

How Typhoid Fever Spreads: The Invisible Pathways of Infection

Typhoid fever spreads primarily through⁽¹⁾:

• Contaminated food (seafood, raw vegetables, fruits)
• Contaminated water
• Touching contaminated toilet then touching food without proper hand washing
• Close contact with an infected individual
• Sexual contact in rare cases

Picture this: if someone handling your food hasn’t washed their hands properly after using the restroom, the bacteria can easily make its way into your meal. Poor sanitation and hygiene are the primary culprits.

Early Symptoms You Shouldn’t Ignore

The symptoms of typhoid fever may take 6 to 30 days to appear after exposure⁽¹⁾. Early signs include⁽¹⁾:

• Fever (ranging from 102°F–104°F, 38°C–40°C), gradually increasing typically peaking in the afternoon or evening
• Tiredness
• Aches and pains
• Loss of appetite
• Headache
• Nausea
• Stomach pain, sometimes accompanied by constipation or diarrhea
• Dry cough
• Sore throat

In some cases, additional symptoms include:

• Enlargement of the liver and spleen
• A flat, rose-colored rash on the trunk

If untreated, typhoid fever can be fatal in 10–30% of cases⁽¹⁾. However, the fatality rate drops to less than 1% with appropriate treatment⁽¹⁾. Potential complications include gastrointestinal bleeding and changes in brain function⁽¹⁾.

Stay Safe: Precautions and Vaccines for Prevention During Your Travels

When traveling to areas with a high risk of typhoid fever, prevention is key. Here’s how you can protect yourself:

Food and water precautions (also important to prevent Hepatitis A, Traveler’s Diarrhea⁽²⁾:

• Peel fruits and vegetables or wash them with safe, treated water.
• Boil, filter, or disinfect drinking water, and avoid ice cubes unless you’re sure they’re made from safe water.
• Skip raw milk and undercooked seafood to minimize risks.

Typhoid Vaccines⁽²⁾:

• Typhim Vi (injection)
  • One time injection into the muscles
  • A booster dose is recommended every 2 years
  • Inactivated vaccine
