Typhoid (Antrik Jwara)


Typhoid fever is a significant global health concern caused by the bacterium Salmonella Typhi. This article provides a comprehensive overview of typhoid, including its epidemiology, types, underlying mechanisms, risk factors, signs and symptoms, diagnostic methods, treatment options, and preventive measures.


Typhoid fever has been a persistent threat to public health, particularly in regions with inadequate sanitation and hygiene practices. Understanding the causes, symptoms, and effective management of typhoid is crucial for preventing its spread and reducing its impact on communities.

Epidemiology of Typhoid:

Typhoid remains a major health challenge, especially in low-income countries with limited access to clean water and sanitation. The disease is more prevalent in areas with crowded living conditions and poor hygiene.

Types of Typhoid:

Typhoid fever is typically categorized as:

  1. Typhoid Fever (Classical Typhoid):

    • The most common type caused by the bacterium Salmonella Typhi.
    • Symptoms include high fever, headache, abdominal pain, fatigue, and a characteristic rose-colored rash.
  2. Paratyphoid Fever (Paratyphoid A, B, and C):

    • Caused by Salmonella Paratyphi A, B, or C bacteria.
    • Similar to typhoid fever but generally milder, with symptoms such as fever, abdominal discomfort, and gastrointestinal issues.
  3. Enteric Fever:

    • A broader term encompassing both typhoid and paratyphoid fevers, collectively referred to as enteric fever.
  4. Carrier State:

    • Some individuals may become carriers of the bacteria without showing symptoms.
    • Carriers can unknowingly spread the bacteria to others through contaminated food or water.

Pathophysiology of Typhoid:

Typhoid is caused by the bacterium Salmonella Typhi, which is primarily transmitted through contaminated food and water. The bacteria invade the intestinal lining, enter the bloodstream, and spread to various organs.

Risk Factors and Triggers:

Several factors increase the risk of typhoid:

  1. Contaminated Water and Food:

    • Consumption of contaminated water or food, especially in areas with poor sanitation and hygiene practices, is a major risk factor.
  2. Travel to Endemic Areas:

    • Traveling to regions where typhoid and paratyphoid are prevalent increases the risk of exposure.
  3. Inadequate Sanitation:

    • Living in areas with inadequate sanitation facilities raises the risk of bacterial transmission.
  4. Close Contact with Carriers:

    • Close contact with individuals who are carriers of the bacteria increases the risk of transmission.
  5. Immune System Compromises:

    • Weakened immune systems due to conditions like HIV/AIDS or certain medications elevate the risk.
  6. Age:

    • Young children and elderly individuals are more susceptible to severe illness.

Triggers for Typhoid and Paratyphoid Fevers:

  1. Bacterial Infection:

    • Ingesting food or water contaminated with Salmonella Typhi or Salmonella Paratyphi bacteria triggers the onset of these fevers.
  2. Contaminated Water Sources:

    • Consuming water from contaminated sources, such as untreated wells or rivers, can lead to infection.
  3. Contaminated Food:

    • Consuming raw or undercooked foods, particularly eggs, poultry, and dairy products, can introduce the bacteria.
  4. Poor Hygiene:

    • Inadequate handwashing and poor hygiene practices can lead to bacterial transmission.
  5. Person-to-Person Transmission:

    • Close contact with infected individuals or carriers can lead to transmission.
  6. Unsanitary Living Conditions:

    • Living in overcrowded or unsanitary conditions facilitates the spread of bacteria.
  7. Lack of Vaccination:

    • Not receiving the typhoid vaccine in endemic regions leaves individuals vulnerable to infection.
  8. Contaminated Utensils:

    • Sharing utensils, plates, or glasses with infected individuals can lead to transmission.
  9. Inadequate Cooking:

    • Consuming inadequately cooked food allows the bacteria to survive and cause infection.

Sign & Symptoms of Typhoid:

Symptoms of typhoid can range from mild to severe and may include:

  1. Gradual Onset:

    • Symptoms typically develop gradually over several days to weeks after exposure to the bacteria.
  2. High Fever:

    • Sustained high fever, often reaching 103-104°F (39-40°C), is a hallmark symptom.
  3. Weakness and Fatigue:

    • Profound fatigue, weakness, and a feeling of being unwell are common.
  4. Headache:

    • Persistent and severe headache is often present, contributing to the overall discomfort.
  5. Abdominal Pain:

    • Abdominal pain and discomfort, especially in the area around the belly button, are common.
  6. Loss of Appetite:

    • Loss of appetite and a desire to eat less than usual are typical symptoms.
  7. Gastrointestinal Symptoms:

    • Diarrhoea or constipation may occur, often alternating. Bowel movements may become more frequent.
  8. Rose-Coloured Spots (Rash):

    • About one-third of individuals develop a characteristic rash of rose-colored spots on the chest and abdomen.
  9. Enlarged Spleen and Liver:

    • The spleen and liver may become enlarged, leading to tenderness in the upper abdomen.
  10. Cough:

    • A non-productive, persistent cough may develop along with other respiratory symptoms.
  11. Delirium and Confusion:

    • In severe cases, delirium, confusion, or altered mental state can occur.
  12. Bradycardia:

    • Bradycardia (slow heart rate) may be observed in some individuals.
  13. Muscle Aches:

    • Muscle aches and joint pain (myalgia and arthralgia) are common.
  14. Typhoid State:

    • In advanced stages, a “typhoid state” may occur, characterized by sustained fever, extreme weakness, and a drowsy state.

Investigation & Diagnosis of Typhoid:

Diagnosing typhoid involves:

  1. Blood Tests:

    • Widal Test: This traditional test detects antibodies to Salmonella bacteria. It can help confirm the diagnosis, but results may not be definitive in the early stages of infection.
    • Blood Culture: A blood sample is cultured to isolate and identify the bacteria, providing a definitive diagnosis. It may take several days for results to be available.
  2. Stool Culture:

    • Stool samples may be collected to check for the presence of Salmonella bacteria.
  3. Bone Marrow Culture:

    • In severe or suspected cases, a bone marrow culture may be performed to increase the likelihood of bacterial isolation.
  4. Typhidot Test:

    • This rapid test detects antibodies to Salmonella bacteria in the blood. It can provide quicker results than the Widal test but may not be as accurate.
  5. Serological Tests:

    • Enzyme-linked immunosorbent assay (ELISA) tests may be used to detect antibodies specific to Salmonella Typhi.
  6. PCR Testing:

    • Polymerase chain reaction (PCR) testing can detect the presence of bacterial DNA in blood or other samples.
  7. Imaging Studies:

    • X-rays or ultrasound may be performed to assess the condition of organs like the liver, spleen, and intestines.
  8. Serological Rapid Tests:

    • Rapid diagnostic tests are available that detect specific antigens or antibodies associated with typhoid bacteria.

Treatment of Typhoid in Modern Medical Science:

Treatment typically involves:

  1. Antibiotic Therapy:

    • Antibiotics are the primary treatment for typhoid fever to eliminate the bacterial infection. Commonly used antibiotics include ciprofloxacin, levofloxacin, and azithromycin.
    • The choice of antibiotic may depend on factors such as the patient’s age, drug resistance patterns, and severity of illness.
    • Treatment duration typically ranges from 7 to 14 days, and completion of the full course is crucial to prevent recurrence and antibiotic resistance.
  2. Supportive Care:

    • Maintaining hydration through oral rehydration solutions or intravenous fluids is essential to prevent dehydration caused by fever, sweating, and reduced fluid intake.
    • Bed rest is often recommended during the acute phase of illness to conserve energy and promote recovery.
  3. Fever Management:

    • Over-the-counter fever reducers like acetaminophen (paracetamol) can help alleviate fever and discomfort.
  4. Nutritional Support:

    • A balanced diet rich in fluids, electrolytes, and easily digestible foods supports recovery and helps combat malnutrition.
  5. Isolation and Hygiene:

    • Infected individuals should practice good hygiene, including frequent handwashing, to prevent the spread of the bacteria to others.
  6. Hospitalization:

    • Severe cases, complications, or patients at risk of dehydration may require hospitalization for closer monitoring, intravenous fluids, and antibiotic administration. 

Prevention & Precaution for Typhoid:

Preventive measures include:

  1. Vaccination:

    • Typhoid Vaccines: Two types of vaccines are available – injectable and oral. They provide protection against Salmonella Typhi bacteria.
      • Injectable Vi polysaccharide vaccine: Recommended for travellers and those aged 2 years and above.
      • Oral Ty21a vaccine: Administered as capsules, it’s suitable for travellers and individuals aged 6 years and above.
    • Vaccination is particularly important for travellers to endemic areas and those with a high risk of exposure.
  2. Safe Drinking Water:

    • Consume only bottled or boiled water, and avoid ice made from tap water.
    • Use water purification methods such as boiling, filtering, or chemical disinfection.
  3. Hygienic Food Practices:

    • Eat thoroughly cooked foods and avoid raw or undercooked eggs, seafood, and other potentially contaminated items.
    • Peel fruits and vegetables or wash them with safe water before consuming.
  4. Personal Hygiene:

    • Maintain good personal hygiene and cleanliness, including bathing regularly.
  5. Avoid Contaminated Foods:

    • Avoid street food and foods prepared in unhygienic conditions, especially in areas with inadequate sanitation.
  6. Avoid Close Contact with Infected Individuals:

    • If you know someone has typhoid fever, avoid close contact and practice good hygiene to prevent transmission.

Ayurvedic Perspective on Typhoid:

In Ayurveda, typhoid can be understood as an imbalance of the digestive fire (Agni) and accumulation of toxins (ama) in the digestive system. The weakened digestive capacity and impaired immune response are believed to contribute to the development of typhoid. Ayurveda aims to restore Agni and eliminate ama to promote health.

Ayurvedic Treatment Principles for Typhoid:

Ayurvedic treatments for typhoid focus on strengthening digestion, eliminating toxins, and boosting immune function. Some treatment principles include:

  1. Dietary Modifications: Consuming easily digestible foods like rice gruel (kanji) and herbal broths to support weakened digestion.
  2. Herbal Formulations: Using herbs like Ginger, Turmeric, and Neem for their antimicrobial and immune-enhancing properties.
  3. Fasting: Short-term fasting under supervision to allow the digestive system to rest and recover.
  4. Panchakarma: Detoxification therapies like Virechana (therapeutic purgation) to eliminate accumulated toxins.

Ayurvedic Lifestyle Recommendations for Typhoid:

Ayurveda suggests lifestyle practices to prevent and manage typhoid:

  1. Rest and Hydration: Allowing the body to rest and staying well-hydrated to aid recovery.
  2. Hygiene: Practicing proper hygiene and maintaining cleanliness to prevent infection.
  3. Stress Management: Engaging in relaxation techniques like meditation to support overall well-being.

The Role of Ayurveda in Typhoid Prevention:

Ayurveda plays a role in preventing typhoid by promoting balanced digestion, strong immunity, and overall wellness. Following Ayurvedic guidelines can reduce the risk of developing typhoid and other digestive disorders.

Ayurvedic Researches on Typhoid:

While Ayurvedic texts discuss herbal remedies and dietary practices for digestive health, scientific research on Ayurvedic treatments for typhoid is limited. Further studies are needed to explore the efficacy of Ayurvedic approaches.

Challenges and Future Directions:

Integrating Ayurveda into mainstream healthcare for typhoid management requires addressing challenges such as standardization of treatments, evidence-based research, and collaboration between traditional and modern medical systems. Future research can shed light on the effectiveness of Ayurvedic interventions.


Ayurveda provides holistic insights into preventing and managing typhoid by addressing digestive imbalances, promoting immunity, and adopting a mindful lifestyle. While more research is needed, Ayurvedic principles, herbal remedies, and lifestyle adjustments can complement modern medical approaches and contribute to better health.
