Measles virus is one of the major causes of rash and fever in children in developing countries. Although measles vaccines and measles-containing vaccines were well-developed and widely used in children, measles virus still caused outbreaks worldwide even where the vaccine coverage are high. In 2014, there were big outbreaks occurring in many countries, including Vietnam. Laboratory results of measles cases played an important role in new outbreak cluster confirmation and monitoring. In this study, we compared different laboratory methods for measles infection to provide information for measles diagnostic strategy. Out of 4,672 suspected cases, laboratory-confirmed measles individuals were 63.0% in which 89% were confirmed by IgM ELISA methods. The detection rate of virus isolation and RT-PCR on respiratory tract samples was 7.3% and 71.4%, respectively. On serum samples, the detection rate of ELISA and nested RT-PCR (nRT-PCR) was 62.1% and 19.6%, respectively. Using ELISA on serum samples collected in acute phase of measles infection could miss about 18.0% of measles cases. The application of nRT-PCR on acute serum will improve the measles virus genotype information and supplement results for serological methods.
