Sentinel surveillance

Posted by hmohammed on 03 Nov 2010 at 13:57 GMT

In many dengue outbreaks, it is often impractical to perform laboratory confirmation on all suspected cases, especially in settings where laboratory testing is performed outside the country. Sentinel surveillance may be a more feasible approach. One potential means of doing this would be to select geographically dispersed sentinel sites (the hospital and a few private physicians with high patient loads) and conduct enhanced surveillance in those settings. Yet another useful source of sentinel data could be generated by a routine review of diagnosed dengue in travelers from non-endemic areas to the country of interest.
