Dengue - Multistate (world) - Monitoring seasonal epidemics
Opening date: 20 April 2006 Latest update: 14 March 2013
Epidemiological summary
Europe: There have been no reports of confirmed autochthonous dengue infections in Europe in 2013, besides the on-going dengue outbreak in Madeira.
Asia: Cambodia, Lao PDR and Singapore have all reported more cases so far in 2013 than in 2012 for the same time period. Recent trends show declining dengue activity in Australia, Cambodia and the Philippines. In Thailand, there are currently 1 000?1 500 new cases reported each week throughout the country, four times higher than during the same period last year.
The Caribbean: In Guadeloupe 500 people were recorded to have dengue fever since January 2013, including eight hospitalisations. Of these, four cases were diagnosed as severe dengue infection. Three serotypes, DENV-1, DENV-2 and DENV-4 are co- circulating since the beginning of 2013 the predominant strain being DENV-1.
Central and South-America: High dengue activity is reported across Central America. In South America, continued high number of cases are seen in Argentina, Ecuador, Paraguay, Brazil and Venezuela. Increasing number of cases are reported in French Guyana with three serotypes co-circulating: DENV-1, DENV-2 and DENV-4.
Pacific: New Caledonia continues to see sustained dengue activity. A dengue outbreak with over 300 clinical dengue cases including two fatalities is still on-going in the Solomon Islands where the Solomon Islands Cabinet has approved the establishment of a National Task Force to address the outbreak. Vanuatu?s Department of Health has reported six suspected cases of dengue fever. Samples have been sent to New Caledonia for confirmation. In addition, there are two imported confirmed cases in law students from the Solomon Islands.

ECDC assessment
ECDC monitors individual outbreaks, seasonal transmission patterns and inter-annual epidemic cycles of dengue through epidemic intelligence activities in order to identify significant changes in disease epidemiology.
Of particular concern is the potential for the establishment of dengue transmission in Europe. Before the current outbreak in the Autonomous Region of Madeira, local transmission of dengue was reported for the first time in France and Croatia in 2010. Imported cases are detected in European countries, highlighting the risk of locally acquired cases occurring in countries where the competent vectors are present.
Actions
ECDC has published a technical report on the climatic suitability for dengue transmission in continental Europe and guidance for invasive mosquitoes? surveillance.
