Dengue Fever

12 min read

Dengue fever is a mosquito-borne viral infection that is found in tropical and subtropical regions around the world. It is caused by four different types of dengue virus, and is transmitted by the Aedes aegypti mosquito. Dengue fever is a serious and potentially fatal disease, and is estimated to affect up to 400 million people each year.

History of Dengue Fever

Dengue fever has been around for centuries, with the first recorded cases dating back to the 18th century. It is believed to have originated in Africa, and spread to other parts of the world through trade and travel. In recent years, the incidence of dengue fever has increased dramatically, due to increased global travel and the spread of the Aedes aegypti mosquito.

Geographic Distribution

Dengue fever is found in tropical and subtropical regions around the world, including parts of Africa, Asia, the Caribbean, Central and South America, and the Pacific Islands. It is most common in urban and semi-urban areas, where the Aedes aegypti mosquito is found in abundance.

Prevention and Control

The best way to prevent dengue fever is to avoid being bitten by mosquitoes. This can be done by using insect repellents, wearing long-sleeved clothing, and staying indoors during peak mosquito hours. Additionally, it is important to reduce mosquito breeding sites by eliminating standing water and using insecticides to kill adult mosquitoes.

Symptoms

Common Symptoms of Dengue Fever

  • High fever (up to 105°F)
  • Severe headache
  • Pain behind the eyes
  • Joint and muscle pain
  • Nausea and vomiting
  • Rash
  • Mild bleeding (e.g., nose or gums bleed, easy bruising)
  • Low white blood cell count

It is important to note that not everyone who is infected with dengue fever will experience all of these symptoms. Some people may only experience a few of them, while others may experience more severe symptoms. If you have recently traveled to an area where dengue fever is common and experience any of these symptoms, it is important to seek medical attention right away.

Complications of Dengue Fever

In some cases, dengue fever can lead to more serious complications, such as dengue hemorrhagic fever (DHF) or dengue shock syndrome (DSS). DHF is a severe form of dengue fever that can cause bleeding, low blood pressure, and even death. DSS is a life-threatening condition that can cause shock, organ failure, and death. If you experience any of the symptoms of dengue fever, it is important to seek medical attention right away to prevent these complications.

Causes

What Causes Dengue Fever?

Dengue fever is caused by four different types of dengue virus, which are spread by the Aedes aegypti mosquito. The virus is transmitted when an infected mosquito bites a person, and the virus enters the bloodstream. The virus is most commonly found in tropical and subtropical regions, but it can also be found in some parts of the United States. The virus is most active during the rainy season, when the mosquito population is at its highest.

Risk Factors for Dengue Fever

Anyone can be at risk for dengue fever, but there are certain factors that can increase the risk. People who live in or travel to areas where the virus is found are at an increased risk. People who live in areas with poor sanitation and inadequate mosquito control are also at an increased risk. Additionally, people who have a weakened immune system, such as those with HIV/AIDS, are at an increased risk of developing dengue fever.

Preventing Dengue Fever

The best way to prevent dengue fever is to avoid being bitten by mosquitoes. This can be done by wearing long-sleeved shirts and long pants, using insect repellent, and avoiding areas where mosquitoes are likely to be found. Additionally, it is important to practice good sanitation and mosquito control in areas where the virus is found. This includes eliminating standing water, which is where mosquitoes lay their eggs.

Getting a Diagnosis

Physical Exam

A physical exam is the first step in diagnosing dengue fever. During the exam, the doctor will look for signs of fever, rash, and joint pain. They may also take a blood sample to check for signs of infection.

Blood Tests

Blood tests are used to confirm a diagnosis of dengue fever. The most common test is a complete blood count (CBC), which looks for signs of infection. Other tests may include a platelet count, which looks for signs of bleeding, and a dengue IgM antibody test, which looks for antibodies that are specific to dengue fever.

Imaging Tests

Imaging tests such as X-rays and ultrasounds may be used to look for signs of organ damage caused by dengue fever. These tests can help the doctor determine the severity of the infection and the best course of treatment.

Treatment

Once a diagnosis of dengue fever has been made, the doctor will recommend a course of treatment. Treatment may include rest, fluids, and medications to reduce fever and pain. In severe cases, hospitalization may be necessary.
