Dead crow found in Guelph tests positive for West Nile virus
Wellington-Dufferin-Guelph Public Health said Wednesday there are currently no human cases, but the presence of the virus in the crow shows it's circulating and transmission is possible.
The virus is transmitted through the bite of an infected mosquito.
"While the risk of severe illness is low, we encourage everyone to take simple precautions to prevent mosquito bites," associate medical officer Dr. Matthew Tenenbaum said in a release.
Public health says the most effective way to avoid the virus is to reduce the risk of getting mosquito bites. People can do that by:
Wearing light-coloured clothing (including long sleeves and pants).
Using an approved mosquito repellant.
Repairing holes in screen doors and windows.
Reducing breeding places for mosquitos by removing standing water from properties including draining potential reservoirs like flowerpots and kids' pools and by frequently replacing water in bird baths and other water features.
Public Health Ontario says on its website that most people infected with West Nile virus do not show symptoms.
Others may experience a fever, head and body aches, fatigue, rash or in more serious cases, meningitis (swelling of brain and/or spinal cord) or encephalitis (brain swelling).

Create Account Data released by Public Health Ontario shows no additional illnesses in the area covered by Southwestern Public Health, which in April accounted for 45% of the province's cases and the highest count in Canada. The benchmark comes after the region reported just one new case for each of the previous three weeks, although there are nine new cases in the neighbouring health unit of Middlesex-London. Public Health Ontario says they are among 22 new cases over the past week, including four reported by the Grand Erie health unit, eight in the summer destination of Huron Perth and one in Chatham-Kent. Southwestern Public Health said earlier this week it was ending local weekly measles reports but stressed that the outbreak was not over.

Read More The province's weekly case additions have hovered around the 20s and 30s lately, with 32 additions logged last week, 21 the week before that, and 11 on July 3. The latest data brings the province's total number of infections to 2,298 since an outbreak began in October. Meanwhile, the Alberta Medical Association is hoping to draw more attention to its outbreak, which logged 1,511 cases as of Thursday. An expert AMA panel called the province's measles situation an epidemic on Wednesday. 'We're probably just seeing the tip of the iceberg,' Dr. Lynora Saxinger, an infectious diseases specialist with the University of Alberta, said on the panel. This advertisement has not loaded yet, but your article continues below. Dr. James Talbot, former chief medical officer of health in Alberta, said describing the spread as an epidemic would appropriately raise the level of urgency for parents to get their kids vaccinated before school resumes. Talbot urged the government to make measles vaccines available to infants as young as six months old in Edmonton and Calgary. The province offers early shots to infants in the hardest hit south, central and north zones. The Alberta government said more than 82,000 measles vaccines were administered across Alberta between March 16 and July 12, representing an increase of more than 55% compared to the same time last year. Nova Scotia reported 30 cases of measles in the northern zone Thursday, up from the single case reported July 7. Health officials say they believe the cases stemmed from travel within Canada to regions where measles is circulating. Manitoba said there were 12 new cases in its weekly report Wednesday, bringing its total number of confirmed infections to 158. Sports Canada Editorials World Toronto & GTA

N.S. public health reporting 30 cases of measles in northern part of province
A dose of the measles, mumps, and rubella (MMR) vaccination awaits the next patient during a vaccine clinic in St. Thomas, Ont., on Tuesday, March 4, 2025. THE CANADIAN PRESS/Geoff Robins HALIFAX — Nova Scotia Health says there are now 30 cases of measles in the northern part of the province. The health agency had reported a single case on July 7 in the northern zone, and says it is believed that all 30 infections stem from travel within Canada to regions where measles is known to be circulating. 'Currently, new cases are mainly found in large households and specific, small communities with close contact,' said a Thursday statement from Nova Scotia Health. Health officials said the rise in cases was expected because it's common for secondary infections to appear within seven to 21 days after initial measles cases are identified. Eight of 30 cases in the northern zone have been lab-confirmed and the remaining are considered confirmed based on patients' household exposure and symptoms. Despite the rise in infections, the risk to the general public is still considered low. The provincial health agency is reminding Nova Scotians that the best protection against measles is vaccination, and every person born after 1970 should have two doses of the measles-mumps-rubella vaccine after their first birthday. Nova Scotia's Department of Health says 93.4 per cent of children who turned two years old in 2024 had received one dose of the measles vaccine, and 78.6 per cent were fully vaccinated with two doses. A spokesperson with the department says actual measles vaccination rates in Nova Scotia may be higher 'because of under-reporting.' Scientists, meanwhile, say that a population needs a vaccination rate of 95 per cent — with two doses — to stop measles from spreading. In May, a single case of measles was reported in the Halifax Regional Municipality, but there were no secondary infections identified with the original case, now considered 'resolved.' This report by The Canadian Press was first published July 24, 2025. By Lyndsay Armstrong
