Chikungunya and Dengue Fever are two ailments which bear a host of similarities with each other. In fact, the symptoms for both the diseases include:

High fever
A headache
Pain in the area behind the eyes
Joint pain
Rash
Fatigue
Nausea

Both of them are viral infections that are transmitted to humans through the bite of the Aedes mosquito. The Aedes aegypti is associated more with the spread of dengue while the Aedes albopictus is more often the Chikungunya virus carrier. However, both types of mosquitoes can spread both Chikungunya as well as Dengue Fever and a person can have both the diseases at the same time as well. Despite these common factors, there is a wide difference between Chikungunya and Dengue Fever.

Criteria	Chikungunya	Dengue Fever
Virus carrier	Aedes aegypti, as well as Aedes albopictus mosquitoes, can both cause Chikungunya through their bite.	Dengue is caused only by the Aedes aegypti mosquito
Virus	Chikungunya is caused by the Togaviridae alphavirus	Dengue is caused by the Flaviviridae flavivirus.
The incubation period of the virus	It takes 1 -12 days for the symptoms to appear prominently	Dengue fever has a longer virus incubation period of 3-7 weeks
Duration of the condition	Chikungunya affliction stays for almost 1-2 weeks	Dengue fever stays for a longer duration of 4-7 weeks
Diagnosis of the disease	ELISA assay is used to measure the levels of immunoglobin in order to identify the chikungunya virus.	ELISA test is performed for detection of antibodies to Flaviviridae flavivirus.
Initial Symptoms	Fever, joint pain, headache, rashes are the first signs of the disease	Fever, joint pain, muscle pain, headache, eye infection rashes are the initial symptoms
Swelling	Mild swelling is there	More swelling is present than Chikungunya and it persists even after the fever has been cured.
Blood Platelet Count	Difference between Chikungunya and Dengue is characterized by the platelet count which is lower than 150,000 platelets per microliter of blood in case of Chikungunya.	Dengue Fever presents a platelet count that falls below 10,000 platelets per microliter of blood.
Body pain	Body pain is present	Body pain is there and the intensity is more than that of Chikungunya
Rash	A rash appears on the face, trunk, limbs, palms, and feet	Rashes are present on the face, hands, and legs
Joint pain	Extreme joint pain is there around hands and knees which may persist even after the patient is cured and all the other symptoms are gone. Many people suffer from a chronic joint pain after suffering from Chikungunya.	Joint pain occurs in knees and shoulders but it is not as high as in Chikungunya
Muscle Pain	Muscle pain is not present	There is muscle pain on the back side of the arms and legs.
Bleeding	There is no bleeding	In some cases of Dengue fever, the patient may experience bleeding especially in extreme cases of Dengue Haemorrhagic Fever
Breathing problems	There is no breathing problem	Some patients may face breathing issues in Dengue
Neurological problems	Rare cases of Chikungunya develop neurological problems	This problem is not present in Dengue
Lymph nodes	Lymph nodes are normal	The lymph nodes in the neck and groin get enlarged
Fatality	One of the main points of difference between Chikungunya and Dengue Fever is the fatality. Chikungunya is rarely fatal.	Dengue fever can be fatal and the number of fatalities due to Dengue till date is much higher than that of Dengue.
Vaccines	No vaccine is available for Chikungunya	Some dengue vaccines are being tested but they have not been clinically approved as of now.
Home remedies	Ginger and green tea relieve the inflammation	Brew made by steeping the neem leaves increases both blood platelet count and white blood cell count. Papaya tree leaves are a natural cure for Dengue fever. Juice made out of the papaya tree leaves helps in increasing the platelet count

There is no difference between Chikungunya and Dengue as far as the prevention from the disease and cure for both of them go. Over the counter, fever and pain-relieving medications are generally prescribed by doctors along with the advice to intake lots of fluids.
