Objective:

To describe the sociodemographic and clinical factors associated with hMPV detection in community settings and characterize its genomic epidemiology, particularly focusing on differences observed before and during the COVID-19 pandemic.

Key Findings:
  • hMPV positivity was significantly higher in clinical specimens (3.9%) compared to community specimens (0.6%).
  • Children aged 0-4 years exhibited the highest positivity rates in both settings.
  • Lower household income and recent international travel were statistically associated with higher hMPV positivity.
  • Subtypes A2b, A2c, B1, and B2 were co-circulating, with a notable increase in subtype B1 post-pandemic.
Interpretation:

The study highlights significant sociodemographic factors influencing hMPV positivity and suggests ongoing circulation of multiple subtypes, which may inform future vaccine development and public health strategies aimed at vulnerable populations.

Limitations:
  • The study may not fully represent all community demographics due to convenience sampling, potentially skewing results.
  • Asymptomatic individuals were excluded, which may lead to an underestimation of hMPV prevalence in the community.
Conclusion:

Understanding the epidemiology of hMPV in community settings is crucial for informing vaccine policies and public health responses, especially in the context of the COVID-19 pandemic and its impact on respiratory illness transmission.
