Comprehensive Guide to Typhoid
Typhoid fever is a life-threatening illness caused by the bacterium Salmonella enterica serotype Typhi (commonly referred to as Salmonella Typhi). Despite significant medical advancements, typhoid remains a pressing public health challenge in many parts of the world, particularly in regions with poor sanitation and limited access to clean water. This guide covers all aspects of typhoid fever, from its symptoms to prevention and vaccination, offering valuable information for travellers and at-risk populations.
What is Typhoid?
Typhoid fever is an acute bacterial infection that spreads through contaminated food, water, or close contact with an infected individual. If left untreated, typhoid can lead to severe complications, including intestinal perforation, organ failure, and even death.
Signs and Symptoms of Typhoid
Symptoms of typhoid fever typically develop within 6–30 days after exposure to Salmonella Typhi. The severity of symptoms varies depending on the individual and the stage of infection.
Early Symptoms (First Week):
- High Fever: Gradually increases, often peaking at 103–104°F (39–40°C).
- Weakness and Fatigue: Persistent tiredness and muscle aches.
- Abdominal Pain: Discomfort or cramping in the stomach area.
- Headache: Common and can be severe
- Abdominal Pain (especially on the right side near the liver)
- Loss of Appetite: Accompanied by nausea or vomiting in some cases.
Symptoms During the Second Week:
- Rose Spots: Flat, rose-coloured rashes may appear on the torso.
- Severe Abdominal Issues: Diarrhoea or constipation, bloating, and an enlarged spleen or liver.
- Mental Changes: Confusion, delirium, or a "typhoid state" (severe lethargy).
- Confusion or difficulty concentrating (a sign of liver encephalopathy)
Advanced Symptoms (If Untreated):
- Intestinal Perforation: Life-threatening condition leading to peritonitis (inflammation of the abdominal lining).
- Sepsis: Infection spreading throughout the body.
- Organ Failure: Particularly of the liver or kidneys.
Causes of Typhoid
Typhoid fever is caused by the bacterium Salmonella Typhi, a strain of bacteria found only in humans. It spreads primarily through ingestion of contaminated food or water.
Faecal-Oral Route
- Drinking water or consuming food contaminated with the faeces or urine of an infected person.
Close Contact
- Living or interacting with a carrier of Salmonella Typhi.
Poor Sanitation
- Use of contaminated water for cooking or washing.
Prevention of Typhoid Fever
Preventing typhoid fever involves addressing its root causes: poor sanitation and unsafe water.
Hygiene and Sanitation:
- Hand Washing: Wash hands with soap and water before eating, after using the toilet, and when handling food.
- Safe Drinking Water: Use boiled, filtered, or bottled water for drinking and cooking.
- Proper Food Hygiene: Avoid raw or undercooked food, especially in areas where typhoid is endemic.
Traveler Precautions:
- Avoid ice in beverages in endemic regions.
- Eat freshly cooked food served hot.
- Steer clear of street food or food from unhygienic sources.
Complications of Typhoid Fever
If left untreated, typhoid fever can lead to severe and sometimes life-threatening complications.
Common Complications:
- Intestinal Perforation:
- A hole in the intestinal wall, leading to severe abdominal pain, infection, and peritonitis.
- Sepsis:
- Infection spreading to the bloodstream.
- Neurological Issues:
- Confusion, delirium, or encephalopathy.
- Chronic Carriage:
- Long-term carriers of Salmonella Typhoid can spread the disease without showing symptoms.
Regions Where Typhoid is Endemic
Typhoid fever is prevalent in regions with limited access to clean water, inadequate sanitation, and poor hygiene practices.
High-Risk Regions:
- South Asia: India, Pakistan, Bangladesh, and Nepal.
- Sub-Saharan Africa: Nigeria, Democratic Republic of Congo, and other densely populated areas.
- Southeast Asia: Indonesia, Vietnam, and the Philippines.
- Parts of Latin America and the Caribbean: Mexico and Haiti.
Factors Contributing to Endemicity:
- Rapid urbanisation without adequate sanitation infrastructure.
- Seasonal floods contaminating water sources.
Things to Take Care of After Typhoid
Recovery from typhoid fever requires attention to nutrition, hydration, and follow-up care to ensure no long-term complications.
During Recovery:
- Adequate Rest: Avoid strenuous activities and allow time for full recovery.
- Balanced Diet: Include easily digestible, nutrient-rich foods like bananas, rice, toast, and yogurt.
- Hydration: Drink plenty of fluids to combat residual dehydration.
Post-Recovery Follow-Up:
- Consult your healthcare provider to ensure the infection is fully cleared.
- Chronic carriers may require additional treatment to eradicate the bacteria from their system.
