In the study of infectious diseases, a critical and complex phenomenon is the transmission of viruses across different host species. Such events can lead to significant outbreaks and pandemics, highlighting the urgent need for a deeper understanding of the mechanisms underlying these transmissions. Recently, attention has shifted towards elucidating patterns of host-virus interaction and the evolutionary adaptations that allow viruses to jump between species. Despite substantial progress, there are crucial gaps concerning specific viral mechanisms and host vulnerabilities.
One emerging concern is the increasing risk of avian influenza transmission to humans, particularly from high pathogenicity avian influenza (HPAI) H5N1. Recent outbreaks in poultry and wild bird populations have raised alarms due to sporadic human infections, often with severe outcomes. A notable example is the detection of H5N1 in dairy cattle in the United States, with subsequent cases of human infection reported among farm workers. These incidents highlight the potential for avian influenza viruses to acquire mutations that enhance human transmissibility, posing a significant public health threat.
This research topic aims to establish a comprehensive understanding of how viruses adapt and transmit across diverse species barriers, focusing on identifying the factors that facilitate or hinder this process. By exploring these dynamics, the research seeks to provide a foundation for predictive models of future zoonotic transmission events and to improve intervention strategies.
To gather further insights into these complexities, we welcome articles addressing, but not limited to, the following themes:
• Evolutionary biology of viruses and host range mutations
• Ecological impacts on viral transmission pathways
• Comparative studies of viral mechanisms in different species
• Role of environmental changes in shaping transmission dynamics
• Advances in molecular techniques for tracing viral origins and pathways
