Viruses transmitted by mosquitoes cause dengue fever. Dengue is common in tropical and subtropical regions. When a mosquito bites a person infected with the virus, the virus enters the mosquito. When this mosquito carrying the virus bites a healthy person, the virus is transmitted into the body of a healthy person. In this way, the virus causing dengue fever is transmitted from one virus-affected person to the other healthy person by the mosquito.
Even after recovering from dengue virus, risks of developing a severe form increase after the mosquito infects the person more than once. Prevention of mosquito bites is advisable. Using a mosquito repellant and reducing the habitat of mosquitoes in the surroundings can be of great help.
Signs and Symptoms of Dengue Fever
Symptoms associated with dengue fever include joint pain, high fever, muscular pain, and skin rashes. A severe form of dengue fever may cause symptoms like bleeding, low blood pressure, and even death. Children and teenagers may not experience any symptoms of dengue fever. Signs and symptoms generally appear four to 10 days after the mosquito bite. These symptoms may last for up to 30 days. Mild signs and symptoms of dengue fever may be misdiagnosed as flu. Common symptoms of dengue fever include:
- Pain behind the eyes
- Swelling of the lymph nodes
- Fever (up to 106 degrees Fahrenheit)
- Pain in joints, muscles, and bones
- Skin rashes
- Minor bleeding from the nose or gums
Dengue hemorrhagic fever is the severe form of dengue fever. Its symptoms include circulatory collapse, abdominal pain, and hemorrhage. Severe cases of dengue fever may cause the following symptoms:
- Persistent vomiting
- Problems in lungs, heart, and liver
- Bleeding from the mouth and nose
- Severe pain in the abdomen
- Bleeding under the skin
Doctors diagnose dengue fever through blood tests. A blood test can help detect the presence of this virus and its antibodies. A vaccine for treating dengue fever is still under development. Taking proper rest and drinking plenty of fluids can be helpful for patients. At an early stage, pain relievers can be helpful, but medicines that may cause bleeding should be avoided. If symptoms worsen, the patient should immediately visit the hospital.
