Typhoid Fever: Causes, Symptoms, Diagnosis, Treatments, Recovery
In this detailed article, we will explain what typhoid fever is, how it spreads, its symptoms, diagnostic tests, treatment options, and effective preventive measures. This guide is written to help readers understand typhoid clearly and take timely action to protect their health.
What Is Typhoid Fever?
Typhoid fever is a bacterial infection caused by Salmonella Typhi. This bacterium enters the human body through contaminated food or water and primarily affects the intestinal tract. From there, it can spread into the bloodstream and affect multiple organs if not treated on time.
Typhoid is more common in regions where:
- Clean drinking water is not easily available
- Food hygiene is poor
- Sewage systems are inadequate
- Hand hygiene practices are lacking
In India and other South Asian countries, typhoid is frequently seen during the monsoon season, when water contamination increases.
How Does Typhoid Spread?
Typhoid spreads mainly through the fecal-oral route. This means the bacteria pass from an infected person’s feces into food or water, which is then consumed by others.
Common Causes of Typhoid Infection
- Drinking contaminated or unboiled water
- Eating food prepared by an infected person who did not wash hands properly
- Consuming street food, cut fruits, salads, or uncovered food
- Using water contaminated with sewage or human waste
- Poor sanitation and open defecation
- Lack of handwashing before meals
Roadside food stalls, unhygienic kitchens, and unsafe water sources are among the most common contributors to typhoid transmission.
Once inside the body, Salmonella Typhi multiplies in the intestines and gradually enters the bloodstream. This slow progression is why early symptoms may appear mild but worsen over time if ignored.
Symptoms of Typhoid Fever
Typhoid symptoms usually develop 7–14 days after exposure to the bacteria. In the early stage, symptoms may resemble other common illnesses, making diagnosis difficult without testing.

Early Symptoms
- Persistent fever that gradually rises
- Weakness and fatigue
- Headache
- Loss of appetite
- Body aches
- Dry cough
Advanced Symptoms
- High-grade fever
- Abdominal pain and discomfort
- Diarrhea or constipation
- Nausea and vomiting
- Enlarged liver or spleen
- Confusion or altered mental state
Without proper treatment, typhoid can lead to life-threatening complications, including intestinal bleeding, bowel perforation, and severe dehydration.
Why Is Typhoid Often Misdiagnosed?
Typhoid fever shares symptoms with other illnesses such as:
- Viral fever
- Malaria
- Dengue
- Chikungunya
Because of these similarities, laboratory testing is essential for accurate diagnosis. Treating typhoid without confirmation can delay recovery and increase complications.
Diagnostic Tests for Typhoid Fever
Doctors recommend specific tests based on symptoms and duration of illness.
1. Widal Test
The Widal test detects antibodies against Salmonella Typhi in the blood.
- Commonly used
- Inexpensive
- Results available quickly
However, it is not always fully reliable, especially in endemic regions, as previous infections or vaccinations may affect results.
2. Blood Culture
Blood culture is considered the gold standard for diagnosing typhoid.
- Detects the bacteria directly
- Most accurate during early stages
- Helps identify antibiotic sensitivity
3. Complete Blood Count
CBC may show:
- Low white blood cell count
- Mild anemia
4. Liver Function Test
Some patients show mild liver enzyme elevation during infection.
5. Additional Tests
In complicated cases, doctors may suggest:
- Urine test
- Stool culture
- Ultrasound of the abdomen
Treatment of Typhoid Fever
Typhoid fever is completely treatable when diagnosed early and managed properly.
1. Antibiotic Therapy
Antibiotics are the mainstay of typhoid treatment. The choice depends on:
- Patient’s age
- Severity of infection
- Local antibiotic resistance patterns
Mild cases are treated with oral antibiotics, while severe cases may require injectable antibiotics and hospitalization.
Never stop antibiotics early, even if symptoms improve. Incomplete treatment can cause relapse or drug resistance.
"I have often observed that patients stop taking antibiotics within 2-3 days as soon as the fever subsides. This is a major mistake that can cause typhoid to return (Relapse). Always complete your full prescribed course."
2. Supportive Care
Along with antibiotics, supportive treatment is crucial:
- Adequate fluid intake to prevent dehydration
- ORS solution
- Coconut water
- Light soups and liquids
- Fever control medications (as prescribed)
3. Diet During Typhoid & Best fruits for typhoid
| Food Category | What to Eat | What to Avoid |
|---|---|---|
| Fluids | Coconut water, ORS, Filtered/Boiled water, Light soups, Fruit juices (strained). | Alcohol, Carbonated drinks (Soda/Cold drinks), Strong Tea/Coffee. |
| Grains & Cereals | Khichdi, Porridge (Dalia), Soft Rice, Idli, Well-cooked Dal. | Whole wheat heavy Roti, Paratha, Pizza, Burger, Maida products. |
| Vegetables | Boiled Potato, Bottle Gourd (Lauki), Ridge Gourd (Torai), Pumpkin. | Raw Salads (Cucumber/Onion), Cabbage, Capsicum, Broccoli. |
| Fruits | Banana, Cheeku, Stewed Apple (cooked without skin), Papaya. | Raw cut fruits from outside, Berries, Dried fruits (Hard to digest). |
| Dairy | Curd (Dahi), Yogurt, Paneer (in small quantity). | Raw Milk, Heavy Cream, Ghee (in excess), Butter. |
| Spices & Oil | Light Turmeric, Cumin (Jeera), Salt (Normal). | Red Chilli powder, Garam Masala, Excess Oil, Deep fried foods. |

4. Typhoid recovery time
I often see patients complaining about severe weakness even after the fever is gone.
One of the most common questions patients ask is, 'When will I feel normal again?' With timely antibiotic treatment, the fever usually subsides within 3 to 5 days. However, the complete typhoid recovery time typically spans 10 to 14 days, depending on the severity of the infection.
It is important to understand that even after the infection clears, post-typhoid weakness and fatigue can linger for several weeks. Many patients make the mistake of rushing back to work or school the moment their temperature drops, which can delay full recovery. Listen to your body—proper rest and a nutritious diet are just as powerful as your medicines in regaining your lost strength.
5. Is typhoid contagious?
Instead, it spreads through the fecal-oral route. This means the bacteria are shed in the stool or urine of an infected person. It infects others only if they consume food or water contaminated due to poor hygiene or lack of handwashing.
6.Recovery Side Effects
- Hair loss after typhoid
- Joint pain after typhoid
In medical terms, this temporary condition is often referred to as Reactive Arthritis. It happens because the immune system remains in an 'active' fighting mode, causing inflammation in the joints.
How to manage it?
While this condition is temporary, understanding its management is key to preventing long-term discomfort.
- Rest: Do not exert pressure on your knees immediately.
- Hydration: Continue drinking plenty of fluids.
- Supplements: Sometimes, a short course of Calcium or Vitamin D3 (prescribed by a doctor) helps faster recovery from this post-typhoid weakness.
Typhoid fever is medically referred to as Enteric Fever, while in many Indian households, it is traditionally known as 'Motijhara'. Regardless of the name, it is the same bacterial infection that requires immediate medical attention and hygiene."
Possible Complications of Untreated Typhoid
If typhoid is ignored or improperly treated, it can cause serious complications such as:
- Intestinal perforation
- Internal bleeding
- Severe dehydration
- Sepsis
- Mental confusion or delirium
Prompt diagnosis and complete treatment significantly reduce these risks.
Prevention of Typhoid Fever
Prevention is the most effective way to control typhoid.
Key Preventive Measures
- Drink only boiled or filtered water
- Avoid roadside food and uncovered snacks
- Wash hands with soap before eating and cooking
- Maintain proper kitchen hygiene
- Do not consume raw salads or cut fruits from outside
- Use clean toilets and avoid open defecation
Typhoid Vaccination
Typhoid vaccines are highly recommended for:
- Children
- Travelers
- People living in high-risk areas
- The vaccine:
- Reduces the risk of infection
- Provides long-term protection
- Is safe and effective
Vaccination combined with hygiene practices offers the best defense against typhoid.
Thoughts
Typhoid fever is a preventable and treatable disease, yet it continues to pose a health risk due to lack of awareness and sanitation issues. Clean water, good hygiene, timely diagnosis, complete treatment, and vaccination together can effectively control typhoid.
If you or a family member experiences prolonged fever and digestive symptoms, consult a doctor immediately and avoid self-medication.
Early action saves lives.
