The B.C. Centre for Disease Control (BCCDC) is ramping up efforts to monitor mosquito populations for viruses, particularly the California serogroup virus (CSGv), which has been linked to serious illnesses in children. Following a 2025 study that identified mosquitoes carrying CSGv after four children were hospitalized in 2024, the BCCDC is deploying high-tech traps in various regions for the second consecutive year. Vector specialist Stefan Iwasawa emphasized the importance of understanding changes in mosquito populations due to climate change, which is expanding their habitats. The traps, designed to attract female mosquitoes using dry ice, will be set up by the end of the month, with analysis scheduled for early fall. Health professionals are on alert for CSGv cases, which are now classified as a reportable condition. While the risk of severe illness remains low, symptoms can include confusion and fever, necessitating immediate medical attention. Residents are advised to take precautions against mosquito bites and to eliminate potential breeding grounds around their homes.
