Typhoid Fever: Symptoms, Treatment & Prevention

Typhoid, also known as typhoid fever or enteric fever, is caused by the Salmonella Typhi bacterium (S. Typhi). It is associated with flu-like symptoms, high fever, and diarrhoea. You can spread typhoid even if you are not really showing symptoms but have it. Typhoid can be fatal and must be treated as early as possible with antibiotics. If you reside in or intend to visit a region where typhoid is prevalent, you should consider getting vaccinated.

What is typhoid fever & Its causes?

Typhoid fever is a bacterial illness caused by the bacterium Salmonella Typhi. These bacteria enter your body through contaminated water or food or even through contact with a typhoid-infected person and infects your gut (small intestine), resulting in symptoms such as stomach pain, high fever, headache, and diarrhoea or constipation.

You will often hear parathyroid fever mentioned in conjunction with typhoid fever because paratyphoid fever has symptoms similar to typhoid but is less severe. Salmonella Paratyphi is the causative agent for paratyphoid fever.

S. Paratyphi and S. Typhi are not similar to the bacterium Salmonella, which results in salmonellosis, a common cause of food poisoning, but are related to Salmonella.

Who can be affected by typhoid fever?

Even today, in the remote areas of developing countries with no modern sanitation, typhoid fever is one of the most common illnesses. Typhoid is amongst the common illnesses in South and Central America, South and Southeast Asia, the Caribbean, and Africa.

Moreover, tourists are most vulnerable to this disease when visiting India, Pakistan, or Bangladesh. Fever in typhoid begins slowly and rises every day, potentially reaching 104.9 °F (40.5 °C) (known as stepladder fashion).

Children are considered the most vulnerable to typhoid fever around the world. This might be due to their developing immune systems; however, children with typhoid present milder clinical symptoms than adults.

Signs and symptoms of typhoid fever

Clinical signs and symptoms are likely to appear gradually, typically between 1 and 3 weeks after exposure to the typhoid disease.
Early signs and symptoms of the illness include:

  • Fatigue and weakness
  • Muscle pain
  • Fever
  • Headache
  • Sweating
  • Weight loss and appetite loss
  • Dry cough
  • Pain in the stomach
  • Rashes known as ‘rose spots’, which usually appear on the trunk (stomach and chest).
  • Constipation or diarrhoea

If typhoid fever is left untreated, the symptoms will worsen over the next few weeks, increasing the risk of potentially fatal complications.
Some people’s symptoms and signs may reappear within two weeks after the fever has subsided.

When should you see a doctor?

If you suspect you have typhoid fever, see a doctor right away.
If you become ill while travelling in another country where typhoid is endemic, contact your country’s consulate to obtain a list of practitioners. If you continue to experience symptoms after returning home, consult a doctor who specialises in infectious diseases or international travel medicine. A doctor who is experienced in these fields will be able to evaluate and treat your symptoms quickly and effectively.
Nowadays, it is possible to book your appointment online from the comfort of your home.

How does typhoid fever spread?

Most individuals get infected with typhoid fever by consuming contaminated water or food or even by coming into direct contact with an infected person. Once infected, they can transmit the illness to others via the faecal–oral route.
You can become infected if you consume food that has been handled by a person with typhoid fever who has not washed their hands thoroughly after using the toilet.

Carriers of typhoid

Even after receiving antibiotics, a small percentage of people recovering from typhoid continue to harbour the typhoid bacteria. Such individuals are known as chronic carriers; they have no symptoms or signs of the disease, but they continue to release the typhoid bacteria in their faeces and can infect others.

How is typhoid fever diagnosed?

Typhoid fever will be diagnosed by your health practitioner based on your travel history, symptoms, and lab tests. It is crucial to inform your doctor if you have recently travelled to a region prone to the disease or suspect you have been exposed to someone with typhoid fever; otherwise, they may not prioritise testing for it. Salmonella Typhi is typically identified in a blood culture, stool culture, or another body fluid and tissue culture.
Although a culture test is the most commonly used typhoid test, other tests, for instance a blood test performed to identify antibodies susceptible to typhoid bacteria or a blood test used to inspect for typhoid DNA, may also be used to verify a suspicious typhoid infection.

What is the treatment for typhoid fever?

Antibiotics are used to treat typhoid. Since some new strains of the bacteria are resistant to certain antibiotic treatments, you will be given different antibiotics based on the kind of enteric fever you have and the region where you got sick.
If you are critically ill or experience complications, you may require additional treatments. These treatments will almost certainly necessitate your hospitalisation.

Typhoid complications
If typhoid is not treated, it can lead to serious complications, such as:

  • Perforation of the intestine
  • Internal bleeding
  • Meningitis
  • Brain-related conditions such as seizures, confusion, and delirium
  • Inflammation of the bones (osteomyelitis)
  • Inflammation of the heart
  • Failure of the kidneys
  • Pneumonia, bronchitis, and other respiratory problems

Prevention of typhoid

Typhoid fever can be prevented and controlled with improved sanitation, safe drinking water, and adequate medical care. Unfortunately, achieving these in many developing countries may be difficult. For example, safe drinking water and adequate medical care may not always be available in some parts of a developing region. As a result, many specialists consider vaccines to be an effective way of preventing typhoid fever.
If you live in or plan to visit areas where typhoid fever is common, you should get vaccinated.

Vaccines against typhoid fever

Typhoid fever vaccines are available in two forms of administration, oral and intravenous. However, these vaccines cannot provide protection against typhoid forever, and you will need to get booster shots to stay protected. They significantly lower your risk, but they do not guarantee that you will not get typhoid. Vaccines may provide some immunity against paratyphoid fever, but this is yet to be proven.

  • Oral vaccine: The typhoid oral vaccine consists of four pills taken every other day.
  • Injectable vaccine (shot): The typhoid vaccine is administered in a single dose. It is recommended that you get it at least two weeks before your trip to allow your body time to build up defences (make antibodies) against the typhoid bacteria. Children over the age of 2 years can obtain this typhoid vaccine. To remain protected, you may need to take additional (booster) shots every 2 years.

Because the vaccine will not provide full protection, when travelling to high-risk areas, it is recommended to follow these precautions:

  • You should wash your hands frequently. Washing hands in soapy, hot water is the most effective way to prevent infection. It is advisable to wash hands prior to preparing food, consuming it, and after using the restroom. If you do not have access to water, keep an alcohol-based hand sanitiser handy.
  • Drinking tap water should be avoided. Drinking water contamination is a particular issue in endemic typhoid regions. Thus, you should only consume canned or bottled water and carbonated beverages. Moreover, bottled water that has been carbonated is comparatively safer than non-carbonated water. It is recommended to request beverages without ice. Brushing teeth with bottled water and avoiding swallowing shower water.
  • Raw vegetables and fruits should be avoided, particularly leafy vegetables or fruits that cannot be peeled, because they might have been cleaned in contaminated water. To be completely safe, you should avoid all raw foods while outside.
  • Select foods that are hot. Avoid eating or storing food at room temperature. Foods that are steaming hot are the best. Even though there is no assurance that meals served in the top restaurants are reliable, it is best to stay away from street vendors’ food because it has more chances of being contaminated.

Avoid infecting others

If you are currently recovering from typhoid, the following precautions can help us keep others safe:

  • Take your antibiotics as directed. Take your antibiotics according to your doctor’s instructions and complete the entire prescribed medication.
  • Wash your hands frequently. This is the most crucial thing that can help you prevent the infection from spreading to others. Scrub your hands thoroughly for at least 30 seconds with hot, soapy water, particularly prior to consuming food and after going to the toilet.
  • Avoid touching food. Cooking for others should be avoided until your doctor suggests you’re no longer infectious.

Typhoid FAQs

Is there high fever in typhoid?

Yes, you get high fever in typhoid, it increases gradually and reaches up to 104.9 °F (40.5 °C).

How long does fever last in typhoid?

When treated promptly after symptoms appear, typhoid fever can last for 7 to 10 days. It may last for 3 weeks or more if left untreated. It may take longer to fully recover if you experience complications or a relapse.

What are the signs of typhoid fever recovery?

You will begin to feel better, your fever will decrease, and you will stop getting fever after a few days; however, your gallbladder can harbour S. Typhi bacteria for a long period of time. So, even if you feel better, you may still be contagious. Hence, it is advisable to take all the prescribed medication and follow your doctor’s advice until full recovery.

What is the ending stage of typhoid fever?

The end stage of typhoid fever is the recovery phase. You will start feeling better, and the fever will begin to come down gradually; however, care should be taken until full recovery, as your gallbladder can keep the S. Typhi bacteria alive for a long time and your typhoid may relapse.

Which part of the body is most affected by typhoid fever?

In typhoid fever, your small intestine (gut) is the most affected part as it infects your gut and causes symptoms such as stomach pain, diarrhoea or constipation, and high fever.
