#Serological analysis in #humans in Malaysian #Borneo suggests prior exposure to #H5 avian #influenza near migratory #shorebird habitats

Source: Nature Communications, AbstractCases of H5 highly pathogenic avian influenzas (HPAI) are on the rise. Although mammalian spillover events are rare, H5N1 viruses have an estimated mortality rate in humans of 60%. No human cases of H5 infection have been reported in Malaysian Borneo, but HPAI has circulated in poultry and…

... the combination of #H2, #H5, #H7, #N1, and #N2 #COBRA #antigens presents a potential for the formulation of a universal influenza virus vaccine.

#Dynamics of #influenza #transmission in vampire #bats revealed by longitudinal monitoring and a large-scale anthropogenic #perturbation, BioRxIV: https://www.biorxiv.org/content/10.1101/2024.07.26.605290v1

Mechanistic #models fit under a Bayesian framework, which enabled joint inference from #serological and #molecular data, showed that common vampire bats maintain BIV independently of the currently assumed fruit bat #reservoir through immune waning and seasonal #transmission pulses.

Detected subtypes included 23 cases of pandemic 2009 #H1N1, six of human seasonal #H3N2, three of classical swine H1N1, 13 of triple-reassortant swine #H1N2, seven of triple-reassortant swine H3N2, and seven of swine-origin H3N2 variant. Notably, none of the serum samples tested positive for avian IAV subtypes #H3N8, #H5N3, #H7N7, and #H9N2 or canine IAV subtype H3N2.

''Our experimental studies showed that these #H3N8 viruses were transmissible in #ferrets, and #serological data suggest that the #human population lacks effective immunological protection against it. With its wide geographical distribution and continuing evolution in chickens, other spillovers to humans can be expected and might lead to more efficient transmission in humans.''
