Dengue - Multistate (world) - Monitoring seasonal epidemics
Opening date: 20 April 2006 Latest update: 31 January 2013
Epidemiological summary
Europe:
There have been no reports of confirmed autochthonous dengue infections in Europe in 2013, apart from the on-going dengue outbreak in Madeira.
Asia:
According to an update from WHO Western Pacific Region this week, regional dengue activity is variable across the region. Australia (Cairns, North Queensland), Malaysia, Philippines, Singapore, Cambodia, Lao PDR, Thailand and Viet Nam all reported more cases as compared to the previous year for the same time period.
The recent trend is declining or remains low in Australia, Indonesia (East Java), Philippines, Cambodia, Lao PDR and India. However, Singapore and Malaysia are seeing an increase in activity, and New Caledonia has been seeing high activity since late 2012.
In the Middle East, 13 new cases of dengue fever were recorded in Jeddah (Saudi Arabia) last week.
A recent study in India (Kerala) indicates the possibility of a recent exotic introduction and also a shift from the existing lineage DENV-3 strains to DENV-4. Lineage shifts in DENV-3 strains have been attributed to increase in disease severity in many parts of the world. This is the first notification of the presence of DENV-4 strains in the Indian subcontinent.
Latin America:
Notable dengue activity is reported across Central America, in particular in Mexico and Honduras. For South America, as expected, overall high and increasing dengue activity reported, especially across Colombia, Ecuador, Venezuela, Brazil, Bolivia, Paraguay and northern parts of Argentina. Peru and Uruguay reported a limited number of cases.
The Caribbean:
According to local health authorities, dengue outbreaks are on-going in Puerto Rico, St. Martin (French and Dutch sides), Dominican Republic and Cuba.
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.
