Chikungunya virus

betterknowamicrobe:

Let’s discuss another alphavirus, shall we? Chikungunya, or CHIKV, is a mosquito-borne pathogen on the move.

The virus is carried by Aedes mosquitoes, just like many other arboviruses. Arboviruses are arthropod-borne and include things like yellow fever, dengue fever, West Nile…

A new disease has arrived in the US following its gradual spread across the western hemisphere. Although not new to science, the Chikungunya Virus (CHIKV), discovered in Tanzania in 1955 was previously confined to sub-saharan Africa, Asia and in small footholds in southern Europe. The Chikungunya virus is a relatively small (60-70nm) arthropod-borne group IV ((+)ssRNA) virus, belonging to the family Togaviridae and the genus Alphavirus.
CHIKV attacks primarily the joints and causes debilitating nausea, swelling, joint and muscle pain, rashes and headaches and it is these symptoms that have earned the virus its unusual name, which translates literally as ‘to bend up’— a reference to the pained posture of people whom are infected. The stiffness, inflammation and pain associated with Chikungunya infection may persist for several months after the other symptoms have relented, although a single infection generally confers lifelong immunity. 
Two viral glycoprotein heterodimers known as E1 (shown red) and E2 (yellow) enable the virus to invade susceptible host cells and are the main antigenic determinants, arranged as a beautiful piece of functional architecture in the icosahedral shell of 80 ‘spikes’, encapsulating the virion. The CHIKV E1 glycoprotein is responsible for membrane fusion whereas E2 binds to surface receptors on target cells, following the successful binding of these glycoproteins the virus enters the hosts cell wherein it undergoes an acid triggered conformational change.

It was previously thought that Chikungunya had only one vector, the mosquito Aedes aegypti which is also the vector for Dengue and Yellow Fever among other diseases and prefers a warm tropical climate. However, it has recently been discovered that the Tiger mosquito (Aedes albopictus) which tolerates cooler climes is also capable of spreading the disease, expanding the distributional range to now include central america and Europe and making it possible for local infection to occur in new countries where Chikungunya had previously never been seen.
There is no vaccine or cure for Chikungunya and treatment is limited to analgesics such as naproxen or paracetamol for the symptoms. Of course, prevention is better than treatment so avoiding mosquitos by wearing insect repellant (including during the day as the Tiger mosquito feeds during the daylight hours) and reducing habitat wherein mosquitos can breed by draining standing water and treating other such bodies appropriately.
