    Abstract

    This study was designed to investigate whether saliva could be a feasible alternative to serum for the diagnosis of recent measles infection in a clinic setting. Forty-two paired blood and saliva samples collected 1 to 16 days after onset of illness from 29 patients with clinical measles were tested for specific immunoglobulin (Ig) M by antibody-capture radioimmunoassay. Measles IgM was detected in all serum samples and in 39 (92.9%) saliva specimens. Between 1 and 3 weeks after illness onset, virus-specific IgM was detected in 100% of saliva samples. Measles IgM was also detected in 17 saliva specimens, not paired with blood samples, collected from study patients 5 days to 3 weeks after onset. Our results indicate that salivary IgM detection is a suitable non-invasive method for investigation of notified cases under conditions of routine clinic use.
