Dengue & Chikungunya
D E N G U E
Dengue Hemorrhagic fever is a severe, potentially deadly infection caused by some mosquitos.
CAUSE: Four different dengue viruses are known to cause Dengue Hemorrhagic fever. Dengue hemorrhagic fever occurs when a person is bitten by a mosquito that is infected with the virus. The mosquito Aedes Aegyptis is the main species that spreads this disease.
Symptoms : Early symptoms of the disease include
- Decreased appetite
- Joint/ Muscle pains
- General ill feeling
Diagnosis : The Dengue fever can be detected by doing a simple blood test.
- Arterial blood
- Blood tests ( to find the signs of virus in the blood)
- Coagulation studies
- Platelet count
Treatment: Since the fever is caused by a virus for which there is no cure or vaccine, the only treatment is to treat the symptoms. These treatments may include
- A transfusion of fresh blood or platelets to correct bleeding
- Intravenous(IV) fluids and electrolytes to correct electrolyte imbalances
- Oxygen therapy to treat abnormally low blood oxygen
- Rehydration with intravenous (IV) fluids to treat dehydration
- Supportive care in an intensive care unit or similar setting
C H I K U N G U N I A
- Chikungunya is a viral disease transmitted to humans by infected mosquitoes. It causes fever and severe joint pain. Other symptoms include muscle pain, headache, nausea, fatigue and rash.
- Joint pain is often debilitating and can vary in duration.
- The disease shares some clinical signs with dengue and zika, and can be misdiagnosed in areas where they are common.
- There is no cure for the disease. Treatment is focused on relieving the symptoms.
- The proximity of mosquito breeding sites to human habitation is a significant risk factor for chikungunya.
- The disease mostly occurs in Africa, Asia and the Indian subcontinent. However a major outbreak in 2015 affected several countries of the Region of the Americas.
