The Windsor-Essex County Health Unit has issued a warning about potential exposure to whooping cough (pertussis) at a medical clinic in Leamington. The exposure occurred on June 16, 2026, at the Leamington Medical Walk-In Clinic located at 215 Talbot Street East.
Exposure Details and Symptoms
According to the health unit, individuals who visited the clinic between 9 a.m. and 5 p.m. on that date may have been exposed. Whooping cough is a highly contagious respiratory infection caused by Bordetella pertussis bacteria. Early symptoms resemble a common cold, including runny nose, sneezing, mild cough, and low-grade fever. After one to two weeks, severe coughing fits may develop, often followed by a high-pitched "whoop" sound when inhaling.
The health unit advises anyone who was at the clinic during that time to monitor for symptoms for 21 days after exposure. If symptoms develop, individuals should stay home and contact a healthcare provider by phone rather than visiting in person to avoid spreading the infection.
Vulnerable Populations and Treatment
Whooping cough can be particularly dangerous for infants, pregnant women, and individuals with weakened immune systems. Vaccination is the best protection, but immunity can wane over time. Antibiotics can reduce severity and prevent spread if given early. The health unit recommends that close contacts of confirmed cases receive preventive antibiotics.
Dr. Wajid Ahmed, Medical Officer of Health for Windsor-Essex County, stated: "We are urging anyone who may have been exposed to be vigilant for symptoms and seek medical advice promptly. Pertussis is easily spread through coughing and sneezing, and early treatment is key."
Previous Outbreaks and Public Health Measures
Windsor-Essex has seen sporadic cases of whooping cough in recent years. In 2024, the region reported 15 confirmed cases. Public health officials emphasize the importance of staying up to date with vaccinations, including the Tdap vaccine for adolescents and adults. Pregnant women are advised to get vaccinated during each pregnancy to protect newborns.
The health unit is working with the clinic to identify and notify close contacts. Further updates will be provided as needed. For more information, residents can call the health unit at 519-258-2146 ext. 1420.
