This study represents a measles outbreak caused by the genotype D9 measles virus (MeV), which was imported by Burmese individuals. Urine and throat swab specimens were collected from suspected measles cases. Viruses were isolated, and a 634-bp target fragment of the N gene was amplified by reverse transcription-PCR and sequenced. Phylogenetic results indicated that the 6 isolates belonged to genotype D9 MeV. Through appropriate prevention and control measures, the transmission of genotype D9 MeV was interrupted. Genotype D9 MeV was isolated for the first time in Shandong and was imported by Burmese individuals.
