Typhoid Fever – Causes, Symptoms, Treatment and Prevention

Typhoid fever is a serious illness caused by the bacterium Salmonella Typhi. While it can be life-threatening, timely treatment can significantly reduce its risks. In places where sanitation is lacking, typhoid remains a significant health threat. With improved hygiene and vaccination, the spread of this disease can be controlled. Additionally, proper health coverage, like the plans offered by Bajaj Allianz General Insurance Company, ensures that individuals can get the necessary medical attention without the burden of high costs. This blog will is about the symptoms of typhoid, typhoid fever treatment, typhoid causes, and prevention methods.

What is Typhoid Fever?

Typhoid fever is an infection caused by Salmonella Typhi bacteria, which primarily affects the intestines and bloodstream. It spreads through contaminated food and water and can be passed from person to person. The disease is more common in regions where sanitation is inadequate, especially in South Asia, sub-Saharan Africa, and Southeast Asia. Without proper typhoid fever treatment, this condition can be fatal in up to 30% of cases, though treatment reduces mortality to around 1–4%.

Causes and Transmission of Typhoid Fever

Typhoid is caused by the Salmonella Typhi bacterium, which enters the body through contaminated water or food. The bacteria reside in the intestines and can spread from infected individuals who do not display symptoms. Here are the key typhoid causes and modes of transmission:

• Consuming water or food contaminated with the faeces of an infected person.
• Direct contact with someone who carries the bacteria.
• Eating raw or undercooked food washed in contaminated water.
• Poor hand hygiene after using the restroom, particularly in public or communal areas.
• Inadequate sanitation practices in food preparation.

Symptoms and Early Signs of Typhoid Fever

Recognising the early symptoms of typhoid can lead to timely intervention and prevent complications. The signs usually appear 1–3 weeks after exposure. Here are some of the common symptoms:

1. High fever: The hallmark of typhoid is that the fever gradually increases over several days, often reaching up to 104°F.
2. Headaches: Persistent headaches often accompany the fever.
3. Rash: Rose-coloured spots may appear, especially on the abdomen.
4. Abdominal pain: Pain and discomfort in the stomach region are common.
5. Fatigue: Weakness and lethargy are frequent symptoms.
6. Loss of appetite: Typhoid can lead to decreased hunger or interest in food.
7. Nausea and vomiting: Digestive distress, including nausea and vomiting, often occurs.
8. Constipation or diarrhoea: While many experience diarrhoea, some may have constipation, especially in the early stages.

Risk Factors for Contracting Typhoid Fever

Certain factors increase the likelihood of contracting typhoid:

• Travelling to high-risk areas: Individuals visiting countries with poor sanitation and high typhoid incidence, such as South Asia and sub-Saharan Africa, are at risk.
• Poor hygiene practices: Lack of proper handwashing and unsanitary food handling heightens the risk.
• Living in densely populated areas: Crowded environments with limited access to clean water and toilets increase the chances of transmission.
• Occupation: Food industry workers or healthcare workers exposed to infected individuals may be more susceptible.

How is Typhoid Fever Diagnosed?

Typhoid fever diagnosis relies on various tests that detect the presence of Salmonella Typhi bacteria in bodily fluids. Below is a table outlining the common diagnostic methods:

Nutrition and Dietary Advice for Typhoid Fever Patients

Maintaining proper nutrition is critical during typhoid fever recovery. Here are some dietary recommendations for patients:

• Hydration: Drink plenty of water, coconut water, and clear soups to prevent dehydration.
• Soft, easy-to-digest foods: Opt for soft foods like porridge, boiled potatoes, and rice to avoid straining the digestive system.
• Small, frequent meals: Eating smaller portions at regular intervals helps maintain energy without overburdening digestion.
• Probiotics: Include yoghurt or probiotics to support gut health and restore beneficial bacteria.
• Avoid spicy and fried foods: These can irritate the digestive tract and delay recovery.

Prevention and Vaccination Strategies

Preventing typhoid relies on both vaccination and improved hygiene practices. Here are some effective strategies:

• Vaccination: Typhoid vaccines are available in both oral and injectable forms. Ensure vaccination at least two weeks before travelling to high-risk areas.
• Drink safe water: Always opt for bottled or boiled water when unsure of its source.
• Avoid raw foods: Consume only well-cooked food and avoid raw fruits and vegetables unless peeled personally.
• Good hand hygiene: Wash hands thoroughly before meals and after using the bathroom.
• Avoid street food: Street food, especially in areas with low hygiene standards, can be a source of contamination.

Conclusion

Typhoid fever is a serious but preventable disease that continues to affect millions worldwide. With early diagnosis, typhoid fever treatment through antibiotics can reduce the mortality rate. However, prevention remains the best approach—vaccination, hygiene, and safe food practices are essential to avoiding this illness. Moreover, having health insurance, such as the plans provided by Bajaj Allianz General Insurance Company, can help cover the costs associated with treatment and hospitalisation, providing peace of mind in case of illness. By staying informed and cautious, the risks of contracting typhoid can be significantly minimised.
