Region of Waterloo Public Health has confirmed the community’s first human case of West Nile this year. The update was published online on Friday. West Nile virus is spread through the bite of an infected mosquito and symptoms can start approximately two to 15 days after transmission. Common complaints include a mild fever, headache, muscle aches, stiff neck, swollen glands and a skin rash. While many people don’t have any symptoms, others can be hit hard. “Less than one per cent of human cases develop more severe symptoms,” said public health. Anyone who believes they have been infected with West Nile should seek out medical attention. “Residents should continue to protect themselves from mosquito bites until we experience the first frost,” said Dr. Rabia Bana, the region’s associate medical officer of health, in the media release. “Despite recent cooler fall weather, we have not yet reached the temperature to halt mosquito activity. Take precautions while spending time outdoors and remove any standing water on your property to help reduce mosquito breeding.” Public health also shared the following advice to prevent mosquito bites: People should also never touch a sick or dead bird, as it may also carry the virus. In 2025, only three human cases of West Nile were confirmed in Waterloo Region.
