Rapid Displacement of Dengue Virus Type 1 by Type 4, Pacific Region, 2007–2009
Abstract
Since 2000–2001, dengue virus type 1 has circulated in the Pacific region. However, in 2007, type 4 reemerged and has almost completely displaced the strains of type 1. If only 1 serotype circulates at any time and is replaced approximately every 5 years, DENV-3 may reappear in 2012.
