How to Avoid Typhoid Fever

Typhoid fever is quite common in developing countries and areas with poor sanitation standards. The widespread nature of the disease requires taking special precautions. The best protection against typhoid is vaccination and avoiding risky foods or drinks.

Typhoid is a serious illness caused by the Salmonella typhi bacteria. The bacterium passes from person-to-person through the consumption of contaminated food or water. Typhoid is so widespread that more than 21.5 million people worldwide fall ill annually, according to the World Health Organization.

The typhoid bacterium lives in human intestinal tracts and bloodstreams. It is only carried by humans, and it spreads through the feces of carriers or people who are ill with the disease. It is often spread when sewage contaminates drinking water or water used for washing food. As a result, typhoid is common in areas where sanitation is poor.

Infections tend to develop over time, starting about three weeks after exposure. Symptoms include high fever, weakness, stomach pains, headaches, loss of appetite, diarrhea or constipation. Some patients will develop a flat, rose-colored rash. If the disease goes untreated, death can result.

The typhoid vaccine is available in oral and injectable form. Full immunity can take up to two weeks to develop. Get the vaccine in advance of your departure and potential exposure to the bacteria. Vaccination is a key line of defense, but avoiding risky drinks and food is also important.

Although the disease is treatable with antibiotics, drug-resistant strains make treatment difficult. These variants of typhoid fever thrive in Asia, Africa and other parts of the world. They are typically resistant to first-line antibiotics but are preventable through vaccination.
