What is Enteric Fever?

Enteric fever, also known as typhoid fever, is a systemic infectious disease caused by the bacteria Salmonella enterica serotype Typhi (S. Typhi). It primarily affects the gastrointestinal tract and is characterized by prolonged fever, abdominal pain, and gastrointestinal symptoms.

  1. Transmission: Enteric fever is primarily transmitted through the ingestion of food or water contaminated with the feces or urine of an infected person. It can also spread through direct contact with an infected individual.
  2. Symptoms: The typical symptoms of enteric fever include high and persistent fever, headache, fatigue, loss of appetite, and generalized body weakness. Gastrointestinal symptoms such as abdominal pain, diarrhea or constipation, and nausea may also be present. In some cases, a characteristic rash known as “rose spots” may appear on the abdomen.
  3. Disease Progression: After the ingestion of contaminated material, the bacteria S. Typhi enter the body through the digestive system and invade the intestinal lining. From there, they can enter the bloodstream, leading to bacteremia (presence of bacteria in the blood). The bacteria can then spread to various organs, including the liver, spleen, and bone marrow, causing systemic symptoms and complications.
  4. Diagnosis: Diagnosis of enteric fever involves a combination of clinical evaluation, medical history assessment, and laboratory tests. Blood cultures are typically conducted to isolate and identify the presence of S. Typhi. Additional tests, such as stool cultures, may be performed to rule out other possible causes of gastrointestinal symptoms.
  5. Treatment: Prompt and appropriate treatment is essential for enteric fever to prevent complications and reduce the duration of illness. Antibiotics such as fluoroquinolones or third-generation cephalosporins are commonly used to treat the infection. However, drug resistance to certain antibiotics has become a concern in some regions. Therefore, it is important to tailor the treatment based on local resistance patterns and antibiotic susceptibility testing.
  6. Prevention: Prevention of enteric fever primarily revolves around ensuring safe food and water practices. This includes drinking clean and treated water, practicing good hand hygiene, and consuming properly cooked food. In regions where the disease is endemic, vaccination against S. Typhi is recommended to provide additional protection.

Enteric fever can have severe complications if left untreated, such as intestinal perforation, bleeding, or the spread of infection to other organs. Therefore, early diagnosis, appropriate treatment, and preventive measures are crucial in managing this infectious disease and reducing its impact on affected individuals and communities.

Which disease is most common in Pakistan?

Malaria is one of the most common diseases in Pakistan, particularly in rural areas. It is a parasitic infection transmitted by the Anopheles mosquito, and symptoms include fever, chills, headache, and muscle pain. Malaria is especially prevalent in the northern regions of Pakistan, which have a humid climate and abundant water sources that provide breeding grounds for mosquitoes. The disease can have serious consequences, particularly for children and pregnant women, and can lead to anemia, respiratory problems, and even death. Despite efforts to control malaria through mosquito control and the distribution of insecticide-treated bed nets, the disease remains a significant public health issue in Pakistan, with an estimated 5 million cases reported each year.

There are other several diseases that are common in Pakistan, but some of the most prevalent include:

  1. Dengue Fever: This mosquito-borne viral disease is common in many parts of Pakistan, particularly during the monsoon season.
  2. Tuberculosis: Pakistan has one of the highest rates of tuberculosis in the world, with around 510,000 cases reported each year.
  3. Hepatitis: Hepatitis B and C are both prevalent in Pakistan, with an estimated 8-10 million people infected.
  4. Typhoid fever: This bacterial infection is common in areas with poor sanitation and hygiene, and Pakistan has a high incidence rate.
  5. Polio: Pakistan is one of only three countries in the world where polio is still endemic, with cases reported each year.

It’s important to note that many of these diseases can be prevented or treated with proper healthcare and preventative measures, such as vaccination and mosquito control.
