- A. Dengue is transmitted to people by the bite of an Aedes mosquito that is infected with a dengue virus. The mosquito becomes infected with dengue virus when it bites a person who has dengue virus in their blood. The person can either have symptoms of dengue fever or DHF, or they may have no symptoms.. What are the symptoms of the disease? A. The principal symptoms of dengue fever are high fever, severe headache, severe pain behind the eyes, joint pain, muscle and bone pain, rash, and mild bleeding (e.g., nose or gums bleed, easy bruising).

Review articleNeurological manifestations of dengue infection: A review Dengue is a common arboviral infection in tropical and sub-tropical areas of the world transmitted by Aedes mosquitoes and caused by infection with one of the 4 serotypes of dengue virus. Neurologic manifestations are increasingly recognised but the exact incidence is unknown. Dengue infection has a wide spectrum of neurological complications such as encephalitis, myositis, myelitis, Guillain–Barré syndrome (GBS) and mononeuropathies.

Dengue Fever Dengue fever is a disease spread by the Aedes aegypti mosquito and is caused by one of four dengue viruses. Once you are infected with one of the dengue viruses, you will develop immunity to that virus for the rest of your life. However, you can still be infected with the other three viruses.

- * Disease: The universal name for the disease is Dengue Fever. Other names that are commonly associated with this disease include: Dengue Hemorrhagic Fever ((DHF) Disease caused by Dengue Fever), Breakbone Fever, Dandy Fever, O'nyong-nyong Fever, Dengue shock syndrome (DSS) and Dengue-like Disease (5). Signs/Symptoms: The disease ranges from mild to severe. Mild dengue fever causes chills, high fever (that lasts about five to seven days), rash, severe headache, pain behind the eyes and muscle and joint pain (3, 4). The severe joint pain has given dengue the name Breakbone Fever (3).

Dengue Viruses Viruses are tiny agents that can infect a variety of living organisms, including bacteria, plants, and animals. Like other viruses, the dengue virus is a microscopic structure that can only replicate inside a host organism.he four closely related dengue viruses — DEN-1, DEN-2, DEN-3, and DEN-4 — are found in the same regions of the world. The dengue virus is a roughly spherical structure composed of the viral genome and capsid proteins surrounded by an envelope and a shell of proteins.

dengue fever It is transmitted to humans by the bite of an infected Aedes aegypti mosquito and occurs in tropic and subtropic regions. The disease usually produces a triad of symptoms: fever; rash; and severe head, back, and muscle pain. Manifestations of dengue usually occur in two phases, separated by a day of remission.he virus that causes dengue fever is called an arbovirus, which stands for arthropod-borne virus. Mosquitoes are a type of arthropod. In a number of regions, mosquitoes carry this virus and are responsible for passing it along to humans.

Symptoms include fever, headache, muscle and joint pains, and a characteristic skin rash that is similar to measles.he characteristic symptoms of dengue are sudden-onset fever, headache (typically located behind the eyes), muscle and joint pains, and a rash. The alternative name for dengue, breakbone fever, comes from the associated muscle and joint pains.

Dengue and severe dengue Dengue is a mosquito-borne viral disease that has rapidly spread in all regions of WHO in recent years. Dengue virus is transmitted by female mosquitoes mainly of the species Aedes aegypti and, to a lesser extent, Ae. albopictus. This mosquito also transmits chikungunya, yellow fever and Zika infection.
