The name “Chikungunya” derives from a word in the Kimakonde language, meaning “to become contorted”, and describes the stooped appearance of sufferers with joint pain (arthralgia) as a result of the disease. Through implementing evidence-based control programmes across the world, MENTOR provides those most in need with prevention, surveillance and control of vector borne disease.Ĭhikungunya virus (CHIKV) is an enzootic virus and has been identified in over 60 countries in Asia, Africa, Europe and the Americas. With our expertise and experience in vector borne disease, MENTOR works to educate others of the epidemiology of different types of diseases and how to prioritize key control measures. Alongside malnutrition in the poorest communities, multiple infections decrease the ability of the immune system, meaning that the body cannot fight preventable diseases. People displaced and caught up in conflict or natural crises are even more vulnerable to VBD since little or no shelter and poor sanitation increases exposure to vector contact. Many different factors such as climate change, growing urbanization and changes in agricultural methods cause levels of disease transmission to fluctuate. These devastating diseases have an overwhelming impact in developing countries in the tropics. Vector (carries the disease and disperses reproductive structure)Īccording to WHO, there are more than 1 billion cases and over 1 million deaths from vector borne diseases a year globally.Pathogenic agent (causes the disease e.g. ![]() Transmission of vector-borne disease requires at least three different organisms: ![]()
