We evaluated different approaches for diagnosing measles virus (MV) infection in unvaccinated children and in healthy contact persons (n=194) during a measles epidemic in The Netherlands. MV RNA was detected by reverse-transcriptase polymerase chain reaction in throat-swab specimens from 93% of the patients with clinical symptoms. MV RNA was detected from 5 days before until 12 days after the onset of symptoms. Most patients (88%) also secreted MV RNA in their urine until 5 weeks after the onset of symptoms. Oral fluid proved to be the most practical specimen for the simultaneous detection of MV-specific IgM antibody and viral RNA, which, together, confirmed 93% of measles cases. Viral RNA was also detected in oropharyngeal specimens from 3 healthy contact persons with serological proof of MV infection. The results of this study emphasize the feasibility of combined detection of viral RNA and MV-specific IgM antibodies in oropharyngeal specimens for the diagnosis of clinical and subclinical MV infection.
