Typhoid Fever: Causes, Symptoms & Treatment

By Stermy 7 Min Read

Typhoid fever is a serious bacterial infection caused by Salmonella typhi. If left untreated, it can be life-threatening. This infection is typically spread through contaminated food and water or direct contact with the feces of an infected person.

The main cause of typhoid fever is the bacterium Salmonella typhi, which is found in the feces and urine of infected individuals. It can be transmitted through contaminated food, water, or close contact with infected people.

Poor sanitation and hygiene practices, such as improper disposal of human waste and inadequate hand-washing after using the toilet, can lead to contamination of food and water sources.

Risk factors for typhoid fever include traveling to regions where the disease is prevalent, such as parts of Asia, Africa, and South America. Additionally, individuals working in healthcare, sanitation, or food service are at a higher risk of exposure.

It’s important to note that not everyone exposed to the bacterium will develop typhoid fever. Some individuals may become asymptomatic carriers, meaning they can spread the infection without showing symptoms themselves.

How Do People Get Typhoid Fever?

Typhoid fever can be contracted through contaminated food or water, as well as through close contact with infected individuals. Salmonella typhi can be found in the feces, urine, or vomit of infected people and can contaminate surfaces or objects.

Practicing good hygiene, avoiding untrusted food and water sources, and getting vaccinated can help reduce the risk of infection. Casual contact is not a major risk factor.

Does Typhoid Spread by Kissing?

No, typhoid fever does not spread through kissing. You usually don’t get typhoid fever directly from another person. However, you can contract it if you touch something they’ve handled without washing their hands after using the bathroom.

How Is Typhoid Fever Diagnosed?

Diagnosing typhoid fever involves a combination of clinical evaluation, laboratory tests, and imaging studies. Early symptoms can be non-specific, resembling other common illnesses like the flu or gastroenteritis.

Common diagnostic methods include:

  • Blood Tests: These are the most common tests, detecting antibodies against Salmonella typhi produced in response to the infection.
  • Stool Culture: This test involves analyzing a stool sample for the presence of Salmonella typhi bacteria and is useful for detecting carriers.
  • Urine Culture: A urine sample is tested for Salmonella typhi bacteria, also useful for identifying carriers.
  • Imaging Studies: X-rays or ultrasounds can detect complications like intestinal bleeding or perforation.

Laboratory tests alone may not confirm a diagnosis; clinical evaluation by a healthcare provider is essential to determine appropriate treatment.

Symptoms of Typhoid Fever

Symptoms of typhoid fever can vary in severity and develop gradually over days to weeks after infection. Common symptoms include:

  • High fever (often over 103°F or 39.5°C)
  • Weakness and fatigue
  • Abdominal pain and discomfort
  • Headache
  • Loss of appetite
  • Diarrhea or constipation
  • Rash of flat, rose-colored spots
  • Cough
  • Enlarged spleen and liver

Treatment of Typhoid Fever

Typhoid fever, caused by Salmonella typhi, is treated with antibiotics and supportive care:

  • Antibiotics: Commonly prescribed antibiotics include ciprofloxacin, azithromycin, and ceftriaxone. Your doctor will choose an appropriate antibiotic based on your age, medical history, and infection severity.
  • Supportive Care: Staying hydrated by drinking fluids like water, fruit juices, and electrolyte solutions helps prevent dehydration. Severe cases may require intravenous fluids.
  • Rest: Adequate rest is essential to help your body fight the infection. Taking a break from work or school until full recovery is recommended.
  • Surgery: Rarely, surgery may be needed for complications like intestinal perforation or abscess formation.

Complete the full course of antibiotics prescribed by your doctor to prevent antibiotic resistance and reduce relapse risk.

Complications of Typhoid Fever

Untreated or delayed treatment of typhoid fever can lead to complications, such as:

  • Intestinal Bleeding: Inflammation and ulceration in the intestines can cause bleeding.
  • Intestinal Perforation: Severe ulceration can lead to a hole in the intestines, causing abdominal pain, fever, and sepsis.
  • Encephalopathy: Brain involvement can lead to confusion, agitation, and seizures.
  • Pneumonia: A serious lung infection causing difficulty breathing and other respiratory symptoms.
  • Hepatitis: Inflammation of the liver.
  • Kidney Failure: Rarely, typhoid fever can cause kidney failure, leading to severe complications.
  • Other Complications: Typhoid fever can also cause myocarditis (heart muscle inflammation), arthritis (joint inflammation), and osteomyelitis (bone infection).

Seek medical attention if you suspect typhoid fever, especially if symptoms persist or worsen. Early diagnosis and prompt treatment can prevent complications and improve outcomes.
