Chikungunya case in Spain reported as false positive
Spanish health authorities in the Valencia Province also report that initial results indicating the positive result were not confirmed by the National Reference Laboratory in Madrid. The ECDC states that cases of the disease within the Valencia Province had been from travel to an endemic area, unlike the false positive case.
There are currently 21 cases reported in the province, but there has not been evidence linking these cases to any form of transmission within Valencia.
Chikungunya is a mosquito-borne virus that is largely endemic to the sub-tropical and tropical regions in Africa, Asia, the Pacific, India and in Europe. The virus was found in the Americas and in the Caribbean in 2013. The U.S. Centers for Disease Control and Prevention lists fever and joint pain as the most common set of symptoms of the disease. They report that it is not often fatal, but the symptoms have the potential to be severe to the point of being disabling and joint pain may persist for several months following the infection. Currently no treatment or cure exists for the chikungunya virus.
