Regional dengue activity is variable. Malaysia and Singapore experienced more than a two-fold greater number of reported cases in 2014 compared to 2013, for the same time period. The recent trend continued to decrease in Australia, Cambodia, Lao PDR, Philippines and Viet Nam, and remains low in New Caledonia.
Lao PDR experienced a large dengue year in 2013, peaking in August 2013. However, in early 2014, dengue activity remains low, and substantially lower than during the same time period in 2013.
Malaysia has been experiencing increased level of dengue activity. In early 2014, dengue activity is over 2 times higher than 2013 for the same time period.
Singapore has also been experiencing an increased level of dengue activity. In early 2014, dengue activity is over 2 times higher than 2013 for the same time period.
In addition, dengue and other arboviruses continue to impact several Pacific Islands. New Caledonia experienced a large dengue year, characterized by rapid increase in the number of reported cases since late 2012, followed by a decline in May and low levels since Aug 2013. French Polynesia has been experiencing increasing levels of dengue since mid-2013, with high levels sustained to date (more than 1000 cases reported in 2013). Kiribati, and more recently Fiji, have been seeing higher dengue activity since December 2013. In addition to dengue, Zika virus outbreak (first reported in the Pacific in 2007 from Federated States of Micronesia) is occurring concurrently in French Polynesia and Chikungunya virus outbreak (first reported in the Pacific in 2011 from New Caledonia) in Federated States of Micronesia.
