DIFFERENTIATE BETWEEN DENGUE AND CHIKUNGUNYA
The onset of monsoons not just relieves people from the scorching July sun but also gives rise to a host of diseases. Spiralling cases of both Dengue and Chikungunya have sent concerning alarming bells over the past years.
1. The Genesis
Historically, Chikungunya was referred to as Dengue. It was only after an outbreak of Chikungunya in Makonde Plateau, somewhere near Tanzania, that it was identified as a separate disease.
Dengue fever is a mosquito-borne disease. It is spread by numerous species of the Aedes mosquito. Dengue has become a global cause of concern ever since the commencement of Second World War.
Similarly, Chikungunya is an infection caused by the chikungunya virus. This virus is transferred by two species of the same Aedes type mosquitoes. Chikungunya virus was first isolated by RW Ross in 1953. In India, Chikungunya was never a bigger cause of concern than Dengue, especially in the northern India. However, in the year 2016, there has been an increase in the cases of chikungunya.
2. The Differences

Dengue and Chikungunya, though carried by the same mosquito type, but are caused by different viruses. While Chikungunya is caused by a Togaviridae alphavirus, Dengue is caused by a Flavirideae flavivirus.
The incubation period of Chikungunya is of 1-12 days and the duration varies from one to two weeks. However, signs such as joint pain be for a long time. The incubation period for dengue is of 3-7 weeks while it stays from about four to seven weeks.
