In a recent study published in PNAS, researchers explored the evolutionary dynamics of swine influenza A virus (swIAV) populations in Asia's southern and eastern regions. Study: The genomic landscape of swine influenza A viruses in Southeast Asia. Image Credit: LiyaGraphics/Shutterstock.com Background Swine in Southeast Asia is a primary source of pandemic influenza A viruses (IAVs), causing zoonotic and reverse-zoonotic transmission. Global swine production and trade increase the risk of swine IAV transmission. However, the lack of systematic surveillance infrastructure hinders identifying emerging pathogens in pigs and their potential for zoonotic spillover. Effective surveillance is needed to uncover emerging viral strains,...
