Phylogeographic Dynamics and Spatial Connectivity of Influenza A(H3N2) in Brazil

Wanderley Dias das Chagas, Jessylene de Almeida Ferreira, Luana Soares Barbagelata, Edivaldo Costa Sousa et autres

Influenza A(H3N2) viruses show continuous antigenic and genetic evolution, requiring sustained molecular surveillance to understand their circulation and geographic spread. This study investigated the epidemiological, evolutionary, and phylogeographic dynamics of A(H3N2) viruses circulating in Brazil between 2011 and 2019. Epidemiological surveillance data …

Results From the Third and Fourth WHO External Quality Assessments for the Molecular Detection of Respiratory Syncytial Virus

Fernando Couto Motta, Obadiah Kenji, Ian Barr, Shabana Bi et autres

BACKGROUND: In 2016, the World Health Organization (WHO) initiated the global RSV surveillance programme, which aimed to strengthen laboratory diagnostic capacity and evaluate molecular detection test performance.
