Diagnosis of measles by clinical case definition in dengue-endemic areas: implications for measles surveillance and control

ABSTRACT

In many countries measles surveillance relies heavily on the use of a standard clinical case definition; however, the clinical signs ans symptoms of measles are similiar to those of dengue. For example, during 1985, in Puerto Rico, 22 (23 percent) of 94 cases of illness with rashes that met measles clinical case definition were serologically confirmed as measles, but 32 (34 percent) others were serologically confirmed as dengue (AU)
