Molecular characterization of mumps viruses from the 2022–2023 outbreak reveals circulation of multiple genotypes in Uganda

Key Points

• Circulation of multiple genotypes of mumps viruses indicates significant viral diversity in Uganda.
• Molecular characterization revealed distinct genetic variations in mumps viruses during the outbreak.
• Observational analysis focused on the 2022–2023 outbreak in Uganda, identifying key differences in viral strains.
• The findings suggest a need for enhanced surveillance and vaccination strategies against mumps outbreaks.
