The Dengue Fever is a mosquito borne disease, caused by the dengue virus, which is carried by the Aedes Aegypti Mosquito. The virus is transmitted from an infected mosquito to a human.


Cause of Dengue Fever:

The Dengue Fever is a mosquito borne disease, caused by the dengue virus, which is carried by the Aedes Aegypti Mosquito. The virus is transmitted from an infected mosquito to a human. A mosquito bites a person who is infected with the dengue virus, and the virus is passed on when the mosquito bites someone else. Dengue fever is treatable with proper medical care, but it can be fatal if it left untreated.


Symptoms of Dengue Fever:

Depending on the severity of the disease, symptoms of Dengue fever may vary.

  •     Intense headache
  •     Pain behind the eyes
  •     Vomiting and feeling nauseous


Dengue Hemorrhagic Fever:

Symptoms of Dengue hemorrhagic fever(DHF) include:

  •     Bleeding from the mouth, gums, or nose
  •     Clammy skin
  •     Damage to lymph and blood vessels
  •     Internal bleeding, which can lead to black vomit and feces, or stools
  •     Lower number of platelets in blood
  •     Sensitive stomach
  •     Small blood spots under the skin
  •     Weak pulse

DHF can be fatal if not treated at right time.

  •     Disorientation
  •     Sudden hypotension, or a fast drop in blood pressure
  •     Heavy bleeding
  •     Regular vomiting
  •     Blood vessels leaking fluid
This can result in death if not treated at right time.

Treatment of Dengue Fever:

Dengue is a virus, so there is no specific treatment or cure. Dengue treatment is concerned with relief of the symptoms and signs. For mild fever the treatment includes home remedies such as rest and fluid intake are important. Rehydration salts can also help replace fluids and minerals.

Painkillers, such as Tylenol or paracetamol can help lower fever and ease pain.
Non-steroidal anti-inflammatory drugs (NSAIDs), such as aspirin or ibuprofen, are not advised, as they can increase the risk of internal bleeding.

More severe forms of dengue fever may require intravenous (IV) fluid supplementation, or drip, if the person cannot take fluids by mouth. Sometimes blood transfusion, for patients with severe dehydration may also required. For proper monitoring hospitalization is necessary.

Carica papaya leaf extract (papaya leaf) is an effective treatment for dengue fever. This will increase the platelets count in blood.


Prevention of Dengue fever:

Prevention is always better then cure. The prevention of dengue fever requires control or eradication of the mosquitoes carrying the virus that causes dengue. This require empty stagnant water from old tires, trash cans, and flower pots.

Clothing:

Reduce the amount of skin exposed by wearing long pants, long sleeved shirts, and socks, tucking pant legs into shoes or socks, and wearing a hat.


Mosquito repellents:

For personal protection, use mosquito-repellant sprays.


Mosquito traps and nets:

Nets treated with insecticide are more effective, otherwise the mosquito can bite through the net if the person is standing next to it. The insecticide will kill mosquitoes and other insects, and it will repel insects from entering the room.


Door and window net:

Netting, can keep mosquitos out.

Avoid Perfumes:

Heavily scented soaps and perfumes may attract mosquitos.

Camping gear:

Treat clothes, shoes, and camping gear with permethrin, or purchase clothes that have been pretreated.

Timing:

Try to avoid being outside at dawn, dusk, and early evening. Staying indoors for two hours after sunrise and before sunset will help, as the Aedes aegypti mosquito is a daytime biter with peak periods of biting around sunrise and sunset. 

Stagnant Water:

The Aedes mosquito breeds in stagnant water. Checking for and removing stagnant water can help reduce the risk. To reduce the risk of mosquitoes breeding in stagnant water empty stagnant water from old tires, trash cans, and flower pots.
