Health_Dengue and Chikungunya Differentiation

When I reviewed all I had posted about Health articles I had come to conclude Dengue and Chikungunya have some cases of being diagnosed of having both the illness is because the common factor that is transmitted to people/humans by the bite of an Aedes mosquito but THEY HAVE common and different symptoms. Fatalities related to chikungunya virus are rare. Some of the The preventions are the same to maintain cleanliness where a species of mosquito that breeds in household containers( clean water and stagnant with no cover) and surrounding like in gutter, flower pot, drainage, in the playground where there is unused rubber tire.This mosquito is an aggressive biter during the day, and is attracted to humans for bloodmeals, mosquito repellent and wearing long pants and long sleeves.

The Dengue is transmitted to people by the bite of an Aedes mosquito that is infected with a dengue virus. The mosquito becomes infected with dengue virus when it bites a person who has dengue virus in their blood. The person can either have symptoms of dengue fever or DHF, or they may have no symptoms. After about one week, the mosquito can then transmit the virus while biting a healthy person. Dengue hemorrhagic fever is characterized by a fever that lasts from 2 to 7 days, with general signs and symptoms consistent with dengue fever. When the fever declines, symptoms including persistent vomiting, severe abdominal pain, and difficulty breathing, may develop. This marks the beginning of a 24- to 48-hour period when the smallest blood vessels (capillaries) become excessively permeable (“leaky”), allowing the fluid component to escape from the blood vessels into the peritoneum (causing ascites) and pleural cavity (leading to pleural effusions). This may lead to failure of the circulatory system and shock, followed by death, if circulatory failure is not corrected. In addition, the patient with DHF has a low platelet count and hemorrhagic manifestations, tendency to bruise easily or other types of skin hemorrhages, bleeding nose or gums, and possibly internal bleeding. Dengue cannot be spread directly from person to person.

 The principal symptoms of dengue fever are high fever, severe headache, severe pain behind the eyes, joint pain, muscle and bone pain, rash, and mild bleeding (e.g., nose or gums bleed, easy bruising). Generally, younger children and those with their first dengue infection have a milder illness than older children and adults.

And while 

The Chikungunya fever is a viral disease transmitted to humans by the bite of infected mosquitoes. Chikungunya virus is a member of the genus Alphavirus, in the family Togaviridae. Chikungunya fever is diagnosed based on symptoms, physical findings (e.g., joint swelling), laboratory testing, and the possibility of exposure to infected mosquitoes. There is no specific treatment for chikungunya fever; care is based on symptoms. Chikungunya fever is not usually fatal. Aedes aegypti 
(the yellow fever mosquito), a species of mosquito that breeds in household containers, is an aggressive biter during the day, and is attracted to humans for bloodmeals.
 Aedes albopictus (the Asian tiger mosquito) has also played a role in humantransmission in Asia, Africa, and Europe. Various forest-dwelling mosquito species in Africa have been found to be infected with the virus.

The Aedes aegypti mosquito is the principle vector responsible for transmitting the chikungunya virus to humans.

Chikungunya virus infection can cause a debilitating illness, most often characterized by fever, headache, fatigue, nausea, vomiting, muscle pain, rash, and joint pain. The term ‘chikungunya’ means ‘that which bends up’ in the Kimakonde language of Mozambique.
Acute chikungunya fever typically lasts a few days to a few weeks, but as with dengue, West Nile fever and other arboviral fevers, some patients have prolonged fatigue lasting several weeks. Additionally, some patients have reported incapacitating joint pain, or arthritis which may last for weeks or months. The prolonged joint pain associated with chikungunya virus is not typical of dengue. No hemorrhagic cases related to chikungunya virus infection have been conclusively documented in the scientific literature. Co-circulation of dengue fever in many areas may mean that chikungunya fever cases are sometimes clinically misdiagnosed as dengue infections, therefore the incidence of chikungunya fever could be much higher than what has been previously reported.
The incubation period (time from infection to illness) can be 2-12 days, but is usually 3-7 days. “Silent” chikungunya virus infections (infections without illness) do occur, but how commonly this happens is not yet known. Chikungunya virus infection (whether clinically apparent or silent) is thought to confer life-long immunity. Fatalities related to chikungunya virus are rare.

note: I hope this can help to make everyone to understand both viral infection.
