A tropical mosquito-borne disease, Dengue fever caused by the dengue virus. Symptoms usually start three to fourteen days after infection. These include high fever, headache, vomiting, and muscle cramps. And joint pain, and skin blemishes. Restoration usually takes two to seven days. In a small proportion of cases, the disease progresses to more severe dengue hemorrhagic fever, resulting in haemorrhage, low blood platelets and blood plasma excretion, or dengue shock syndrome, where dangerous Low blood pressure.

Dengue Aedes genus is spread by many species of mosquitoes, especially Aedes aegypti. There are five serotypes of the virus; One type of infection usually gives this type a lifetime immunity, but others only short-term immunity. Later, different types of infections increase the risk of serious complications. Numerous tests are available to confirm the diagnosis, including the detection of antibodies to the virus or it’s RNA.

The methods of diagnostics

Several methods can use to diagnose DENV infection. Two methods, virological tests (which directly detect elements of the virus) and serological tests,  disclose human-derived immune components that are catalyzed in response to the virus). Depending on the timing of the patient’s presentation, the application of different diagnostic methods may be more or less felicitous. Patient samples collected during the first week of the disease should be examined by both serological and virological methods (RT-PCR).

Symptoms of Dengue

When infected with this type of viral infection, a person experiences various symptoms. What kind of symptoms a person experience depends on the stage of the disease at the moment. The following are some of the common Dengue symptoms that a person may experience after contracting this type of viral disease:

  • Nausea
  • Vomit
  • Eye pain (usually behind the eyes)
  • Muscle aches
  • Arthritis
  • Stomach pain
  • Gentleness
  • Bleeding from the nose or gums
  • Blood in the stool
  • Restlessness
  • Irritability
  • Swollen glands

Causes of Dengue

Let’s have look at the Dengue causes:

  • The primary and most important cause of this type of viral infection is a virus of the Flaviviridae family.
  • When the virus infects mosquitoes, especially Aedes mosquitoes, and the infected mosquito bites a healthy person, it causes dengue fever in a healthy person.
  • Other risk factors include a person living or travelling in the tropics.
  • Having a history of dengue fever in the past

Types of dengue

In this case of viral disease, the type of dengue fever especially means the kind of causative agent that is infecting the person. The virus that causes this type of viral disease belongs to the family Flaviviridae. There are 4 serotypes in this Flaviviridae family of viruses. The type of serotype that affects a person is primarily an indication of the type of dengue that is present in the infected person. Below are four types of dengue that cause a viral infection.

•             DENV – 1

•             DENV – 2

•             DENV – 3

•             DENV – 4

Treatment of Dengue

There are various treatments available for this type of viral infection. Here are some Dengue treatments:

•             Blood pressure monitoring

•             Hospital assistant care

•             Intravenous (IV) fluid and electrolyte conversion

•             Transplantation to replace anaemia  Another way to control Dengue is to destroy its habitat. This is done by getting rid of open water sources, or if this is not possible, by adding pesticides or biological control agents to the area. Spraying with organophosphate or pyrethroid pesticides usually, while sometimes done, is not considered effective. Reducing open water storage through climate change is a preferred method of control, given the adverse health effects of pesticides and the fear of greater logistical difficulties with control agents.
