Chikungunya is an infection caused by the Alphavirus chikungunya (CHIKV). [7] [8] [5] The disease was first identified in 1952 in Tanzania and named based on the Kimakonde words for "to become contorted". [5] Symptoms include fever and joint pain. [4] These typically occur two to twelve days after exposure. [5]
Outbreaks of chikungunya, on average, have low mortality rates. [2] As it is generally a nonfatal disease, prevalence rates during most outbreaks are higher than incidence rates. [6] Recently, it was discovered that approximately 39% of the worldwide population resides in environments where the chikungunya virus is endemic. [7]
For example, the human body louse transmits the bacterium Rickettsia prowazekii which causes epidemic typhus. Although invertebrate-transmitted diseases pose a particular threat on the continents of Africa, Asia and South America, there is one way of controlling invertebrate-borne diseases, which is by controlling the invertebrate vector.
Examples are the Zika virus, chikungunya virus, yellow fever and dengue fever. The re-emergence of the viruses has been at a faster rate, and over a wider geographic area, than in the past.
The 2013–2014 chikungunya outbreak represented the first recorded outbreak of the disease outside of tropical Africa and Asia. In December 2013, the first locally transmitted case of chikungunya in the Americas was detected in Saint Martin. Shortly after the first case the disease began to spread rapidly throughout the Caribbean region.

Pathology is the medical discipline that describes conditions typically observed during a disease state, whereas physiology is the biological discipline that describes processes or mechanisms operating within an organism. Pathology describes the abnormal or undesired condition (symptoms of a disease), whereas pathophysiology seeks to explain ...
An example would be the JC polyomavirus, in which its tropism is limited to glial cells since its enhancer is only active in glial cells, [2] and JC viral gene expression requires host transcription factors expressed exclusively in glial cells. [9] The accessibility of host tissues and organs to the virus also regulates tropism.
