Surge of New Human Metapneumovirus Variants in Spain Raises Concerns for Travelers.

A recent study published in the Journal of Infection explores the genetic diversity, prevalence, and evolutionary dynamics of the human metapneumovirus (HMPV) in Spain from 2014 to 2021. The study found that the COVID-19 pandemic disrupted the circulation of HMPV, but it resurged in the summer and autumn of 2021, causing two epidemic peaks. The prevalence of HMPV was higher during the second peak compared to previous seasons, likely because two generations had not yet experienced primary infection. The study provides crucial information on the real-time evolution of HMPV and its impact on public health.
