Listeners, today’s public health alerts in the United States center on heat, vaccinations, infectious disease outbreaks, environmental hazards, and COVID-19 precautions. With much of the country facing a stretch of hot and humid weather, health officials including Public Health Sudbury & Districts and Grand Erie Public Health are issuing heat warnings. Heat warnings trigger when daytime temperatures remain above 29 degrees Celsius and nighttime temperatures stay above 18 degrees, with a humidex of 36 or higher.

Signs of heat-related illness include dizziness, nausea, rapid heartbeat, and dark yellow urine; emergency symptoms should prompt immediate medical attention.
