Researchers from Institut Pasteur in Shanghai and Paris, who have examined the genomes of rhinoviruses found in Shanghai children, found that individuals were often infected by combinations of different viruses. For the first time, the researchers found numerous recombinations in the genome of the newest virus type, rhinovirus-C. Because the rhinoviruses are combining in novel ways, the study warns a more virulent strain may ultimately emerge, one that is capable of “propagation of viruses that are better fit to their host and environment.” More details...
