Viruses are transmitted directly and/or indirectly from human to human and from animal to human. In host cells, virus replication frequently results in an accumulation of mutations, reassortments, and homologous and heterologous recombinations, contributing to their rapid adaptation to environmental changes, often causing the emergence of new virus variants or species. These viral characteristics, in addition to spillover events, have resulted recently in an increasing number of outbreaks, epidemics, and pandemics.The emergence and re-emergence of novel pathogens challenges public health in regard to the development of new diagnostic methods, therapeutics, and prevention strategies and maintaining efficient epidemiological surveillance.Regarding the attention that should be accorded to these kinds of infectious diseases, and for the anticipation of future epidemics, we encourage researchers to submit articles to this research topic surrounding Emerging and Re-emerging Viral Infections.We welcome original research and reviews related to virus epidemiology, pathogenesis, genetic variability and evolution, diagnosis, treatments, and prevention studies. Relevant findings from human, animal, and invertebrate viruses are encouraged.
