Figure 7

Regional DENV serotype data for the period 2005–2010 show similar patterns in each region. Broadly, there was a reduction in the proportion of DENV-1 and an increase in the proportion of DENV-2 in all regions. The proportion of DENV-3 was variable by time and between regions, whereas DENV-4 only remained in circulation throughout this 5-year period in the Central region. DENV, dengue virus. *Data for 2000–2004 not available from source material.
