El ECDC ha publicado el 27 de juio de 2016 el breve documento Preparing for Zika in the EU en el que apunta entre otras cosas al mayor riesgo de tener casos autóctonos de infecciones por ZIKV en Madeira, dado que allí existe Ae Aegypti.
Habla de un brote por chikungunya en 2014 en Montpellier y lo refiere como ejemplo de lo que hay que hacer tras la aparición de un caso. En el artículo CHIKUNGUNYA OUTBREAK IN MONTPELLIER, FRANCE, SEPTEMBER TO OCTOBER 2014, publicado en Eurosurveillance, Volume 20, Issue 17, 30 April 2015 se describe las actuaciones llevadas a cabo en relación con los casos y los sistemas de vigilancia y tratamiento de los insectos en la zona.
In mainland France, since 2006, a chikungunya and dengue preparedness and contingency plan is implemented every year in vector-colonised districts. This plan aims to prevent the transmission and dissemination of these viruses [3,6]. It describes five risk levels defined according to entomological and epidemiological surveillance results. All clinically-suspected imported cases must be reported to the regional health authority in addition to mandatory notification of confirmed cases. Epidemiological investigations are then implemented as well as appropriate vector control measures in each location visited by patients during their period of viraemia. In addition, a network of laboratories practicing chikungunya and dengue diagnosis provides daily reports of their results to the French Institute of Public Health Surveillance regional boards. This enables identifying imported and autochthonous cases not already notified. A national database collects all suspected and confirmed cases identified during the season
Razonan los períodos de vigilancia:
The time after 28 July was considered as the maximal period for viral transmission from symptoms onset of the primary case to symptoms onset of the second case, considering a mosquito lifespan of maximum one month, human incubation of maximum 12 days and human viraemia of seven days.
Active case finding of suspected autochthonous cases was implemented in Montpellier and conurbation: (i) a door-to-door investigation was conducted in the neighbourhood of the autochthonous cases’ residences (200m radius). Nearly 1,000 households were targeted, representing ca 2,250 inhabitants; (ii) information on the event and a request to immediately notify all suspected autochthonous cases to the regional health authority was sent to all GPs and laboratories established in the Montpellier conurbation as well as all six emergency medical services (including the Montpellier UH). In addition, health professionals established within a 2km radius of the cases' residences were contacted by telephone (30 GPs and 11 laboratories).
Ya en una entrada anterior OMS Europa evalua el riesgo de infecciones por ZIKV, pero no hay sitio donde se recoja los casos que se van produciendo, de momento importados referíamos el comentario de la ECDC de que en Madeira y en el Mar Negro es donde hay más riesgo de casos autóctonos, transmitidos por el mosquito, dado que hay en estas zonas Aedes Aegypti.
Además de la transmisión por vector hay que considerar las transmisiones por vía sexual que los datos de Rio de Janeiro y de Colombia destacan como muy importante,

Veo que habla de la presencia de Ae Aegypti solo en Madeira, no en el continente. No nombra el Mar Negro como hacía en anteriores documentos.
