Prevalence of California Serogroup Viruses on the Avalon Peninsula
Arthropod-borne diseases negatively affect humans worldwide. Understanding the biology of the arthropod vectors and the pathogenic organisms they harbour has been a moving target as a result of climate change, degradation of ecosystems, and long distance travel. Two viruses within the California ser...
