Dengue virus (DENV) is the cause of dengue fever.It is a mosquito-borne, single positive-stranded RNA virus of the family Flaviviridae; genus Flavivirus. Five serotypes of the virus have been found, all of which can cause the full spectrum of disease.
Dengue infections are caused by four closely related viruses named DEN-1, DEN-2, DEN-3, and DEN-4. These four viruses are called serotypes because each has different interactions with the...
Dengue viruses are spread to people through the bites of infected Aedes species mosquitoes (Ae. aegypti or Ae. albopictus). These are the same types of mosquitoes that spread Zika and chikungunya viruses. These mosquitoes typically lay eggs near standing water in containers that hold water, like buckets, bowls, animal dishes, flower pots, and ...
The classical form of dengue fever (DF) is characterized by high fever, headache, stomach ache, rash, myalgia, and arthralgia. Severe dengue, dengue hemorrhagic fever (DHF), and dengue shock syndrome (DSS) are accompanied by thrombocytopenia, vascular leakage, and hypotension. DSS, which can be fatal, is characterized by systemic shock.

The dengue virus genome (genetic material) contains about 11,000 nucleotide bases, which code for the three different types of protein molecules (C, prM and E) that form the virus particle and seven other non-structural protein molecules (NS1, NS2a, NS2b, NS3, NS4a, NS4b, NS5) that are found in infected host cells only and are required for replication of the virus.
- How Many Types Are there?
Dengue fever is caused by four different types of viruses. These viruses include Dengue 1, Dengue 2, Dengue 3 and Dengue 4. When a person is infected with dengue, it results in bleeding from the gums, nose as well as skin. A person can develop different types. When a person suffers from bleeding, he is said to be suffering from dengue hemorrhagic fever (DHF). When a person goes into shock, he is said to be suffering from dengue shock syndrome (DSS). If a person is infected with one type of virus and develops infection from a second type of virus, he is said to be suffering from dengue hemorrhagic fever with severe shock. Thus, there are 3 types that a patient can develop.
When a person develops sudden high fever of about 103 to 105°F along with severe headache, pain behind eyes, skin rash, nausea and vomiting, dengue is suspected. The fever tends to last for 5 to 7 days and comes back after 3 to 4 days. The characteristics of dengue fever make it easier to distinguish it from other fevers. These characteristics include the symptoms mentioned earlier as well as muscle and joint pains. The muscle and joint pains give rise to the term breakbone fever, for this tropical disease. Let us have a look at each of the types and know more about the symptoms associated with it. ☛ Classical Dengue Fever Also called simple dengue fever, it does not lead to any complications. The symptoms are exhibited after 5 to 6 days of infection. The rash tends to get healed completely, but there may be a recurring episode of the rash in some cases. The symptoms of this type are as follows – 1. Sudden onset of high fever (up to 105°F) with severe chills 2. Severe headache (espe...
There is no specific treatment for dengue fever. The treatment involves management of the symptoms exhibited. This includes administration of intravenous fluids or oral rehydration therapy. The patient is given pain killers and asked to take plenty of rest. In case of severe complications, the patient is admitted to the hospital. After about a few weeks, most patients recover completely without suffering from any complications. Medical attention is very important to prevent the disease from turning into a life-threatening complication. Simple dengue fever does not lead to any complications and is not considered to be a life-threatening infection. But, if it develops into a hemorrhagic fever or the patient goes into a shock, it could turn fatal. If one develops sudden high fever, with headache, chills, joint pain and other symptoms mentioned above, seek medical attention immediately.
The virus that causes dengue is transmitted by mosquitoes. Dengue fever usually starts with a fever, joint pain, rash and nausea. Without treatment, the virus can cause damage to blood and lymph vessels and lead to dengue hemorrhagic fever, which is marked by difficulty breathing, bruising and bleeding from the nose, gums or under the skin.
Jul 30, 2017 · Dengue virus infection can cause: 1. Dengue fever 2. Dengue hemorraghic fever (DHF) and 3. Dengue shock syndrome(DSS) Before we read about different kinds of fever and symptoms, we suggest you get a general understanding of dengue fever. What is Dengue Fever . Dengue fever is a viral infection caused by the dengue virus that is transmitted ...
Severe dengue most commonly occurs among infants and patients with secondary dengue virus (DENV) infections (i.e., infection with a DENV type different from what they were previously infected with earlier in life). The most widely -cited hypothesis for this occurrence is antibody -dependent enhancement (ADE) of
