The Deadly Dengue Fever: A Tropical Virus Transmitted By Mosquitoes



Mosquitoes have been a major problem in many areas throughout the world and this is due to their ability to transmit deadly illnesses. One type of illness that is transmitted by the Aedes mosquito is dengue fever. These black and white striped mosquitoes can spread dengue which can be deadly for those with weak immune systems and for children under the age of ten.

There are four serotypes of the dengue virus, but dengue is caused by one you can easily get dengue a number of times. Though getting dengue fever can then provide immunity to that type of serotype, you must not ignore the urgency to prevent these mosquitoes from breeding and spreading dengue. Though dengue is mostly rampant in tropical areas, it is still better to be aware of its symptoms and treatments.

Do You Know What Dengue Is?

Dengue fever is an illness that occurs suddenly after experiencing several symptoms. Unfortunately, there are no vaccines available to prevent dengue; prevention is the only option you have to avoid being bitten and to eradicate mosquitoes. You can watch out for these signs to determine if you have been infected –

  • Fever
  • Muscle pain
  • Bleeding
  • Headache
  • Skin rash
  • Vomiting
  • Blood plasma leakage
  • Low levels of blood platelets

The Transmission Of Dengue

While humans are the primary host of this virus, even animals have been known to be infected. The female Aedes mosquito can transmit the virus with a single bite as it is carried by the salivary glands of the mosquito and released through the saliva. The virus enters the white blood cells and reproduces as they are circulated throughout the body.

Thus, cytokines and interferons are produced which are responsible for the number of symptoms experienced. The severe the infection, the more severe the virus production there is affecting the body organs which can prevent sufficient blood supply and reduce the number of platelets that increase the risk of bleeding.

This type of mosquito bites during the day and in the early evenings. Aside from mosquitoes, dengue can be transmitted through infected blood products and organ donations, as well as during pregnancy from mother to child. Those who spend their holidays in the tropics are also at risk of getting infected.

Available Treatments

Unfortunately, there are no antiviral drugs for dengue. Only maintenance of proper fluid balance is essential, while further treatment is dependent on the symptoms. Oral rehydration can be done at home with observation, but the administration of intravenous fluids, as well as blood transfusions at the hospital, maybe necessary especially if you are suffering from other health conditions.

Once you are recovering, intravenous fluids are stopped to prevent fluid overload. Paracetamol may be used for discomfort and fever, but aspirin and ibuprofen medication have to be avoided as these can increase the risk of bleeding. In cases where blood platelets decrease or drop below level or if you show unstable vital signs, blood transfusions are necessary.

It is important you seek medical attention upon recognizing the signs of dengue because prolonging the symptoms for just a few days can be risky. Many have died thinking that they are simply experiencing the flu and have sought medical attention during the later stages of dengue.

The only way to prevent dengue and other illnesses transmitted by mosquitoes is to control or eradicate mosquitoes including those that carry these deadly viruses. Eliminating stagnant water from the home and around the home is necessary. You can also protect yourself by wearing long-sleeved shirts and long pants, applying insect repellants, and proofing your home with mosquito nets or screens.

Seeking professional pest control treatments is also a great way of getting rid of mosquitoes to avoid dengue fever.
