whitby, Ontario – Residents of Durham Region are being advised to take precautions against mosquito bites after health officials confirmed the detection of West Nile virus (WNv) in mosquito samples collected in Whitby. This recent finding marks the 19th positive mosquito batch identified in the region this season, raising awareness about potential health risks.
Mosquito surveillance and Positive Findings
Durham Region Health Department routinely monitors mosquito populations throughout the region. between June and September, mosquito traps are strategically placed and samples are regularly tested. To date, a total of 19 mosquito batches have tested positive for WNv, with cases identified in Clarington (4), Oshawa (7), Ajax (3), Pickering (4), and now Whitby (1). The latest positive sample originated from a Health Department trap located in Whitby.
Understanding West Nile Virus
West Nile Virus is a disease transmitted to humans through the bite of infected mosquitoes. These mosquitoes contract the virus by feeding on infected birds. Importantly, WNv cannot spread directly between people or from birds to humans. According to the Centers for Disease Control and prevention (CDC), approximately 80% of people infected with WNv experience no symptoms. Learn more about West Nile Virus from the CDC.
symptoms and Severity
For those who do develop symptoms, the illness typically manifests as mild health issues. These can include fever, headache, body aches, nausea, vomiting, and skin rash. however,in some instances,more severe symptoms may occur,such as muscle weakness,a stiff neck,confusion,tremors,numbness,and sensitivity to light.symptoms generally appear between two and fifteen days after an infected mosquito bite.
Preventative Measures
While the overall risk of contracting WNv remains low, the Durham Region Health Department strongly encourages residents to implement preventative measures to minimize exposure to mosquitoes. These include:
- Wearing protective clothing, such as long sleeves and pants, along with shoes and socks, especially during dusk and dawn when mosquitoes are most active.
- Applying insect repellent containing DEET or Picaridin, following the product’s safety instructions provided by Health Canada.
- Eliminating standing water around properties, as this provides breeding grounds for mosquitoes.
- Ensuring window and door screens are in good repair to prevent mosquitoes from entering homes.
Additionally, Durham Region actively addresses mosquito populations by treating catch basins and stagnant water areas with larvicide.
Did You Know? Mosquitoes are attracted to dark clothing, so opting for lighter colors can definitely help reduce your risk of being bitten.

Resources and Facts
Residents seeking more information about West Nile virus can contact the Durham Health Connection Line at 905-668-2020 or 1-800-841-2729. Detailed information is also available on the Durham Region website: durham.ca/WestNile.
Pro Tip: Regularly emptying bird baths and pet water dishes can significantly reduce mosquito breeding sites around your home.
Understanding Mosquito-Borne Illnesses
Mosquito-borne illnesses represent a meaningful public health concern globally. Beyond West Nile virus, diseases like Zika virus, dengue fever, and malaria are transmitted by mosquitoes, impacting millions of people each year. Public health organizations continuously monitor mosquito populations and invest in prevention strategies to mitigate the spread of these diseases. Maintaining awareness and practicing preventative measures remains crucial for protecting communities.

Whitby Mosquitoes Test Positive for West Nile Virus: Public Health Alert Issued
Understanding the West Nile Virus Threat in Whitby
Recent testing has confirmed the presence of West Nile Virus (WNV) in mosquito populations within Whitby, Ontario. This public health alert, issued August 23, 2025, underscores the importance of taking preventative measures to protect yourself and your family from mosquito bites. The Durham Region Health Department is actively monitoring the situation and implementing control measures. This isn’t the first instance of WNV in the region,but vigilance is crucial.
What is West Nile Virus?
West Nile Virus is a mosquito-borne illness. It’s transmitted to humans through the bite of an infected mosquito. While many people infected with WNV experience no symptoms at all, approximately 20% will develop West nile fever. A smaller percentage (less than 1%) may develop more severe neurological illnesses like encephalitis or meningitis.
Common Symptoms of West Nile Fever
Fever
Headache
Body aches
Skin rash
Fatigue
swollen lymph glands
Symptoms typically appear between 2 and 15 days after being bitten by an infected mosquito. If you experience these symptoms, especially after recent mosquito exposure, consult your doctor.
Mosquito Control Efforts in Whitby & Durham Region
The Durham Region Health Department is taking several steps to control the mosquito population and mitigate the risk of WNV transmission:
- Mosquito Surveillance: Ongoing monitoring of mosquito populations to identify areas with high WNV activity.
- Larviciding: Applying larvicides to standing water sources to kill mosquito larvae before they can mature.
- Public Education: Raising awareness about WNV and providing facts on personal protection measures (detailed below).
- Adult Mosquito control: In specific situations,targeted spraying of adult mosquito populations might potentially be considered.
Personal Protection: How to Avoid Mosquito Bites
Protecting yourself from mosquito bites is the most effective way to prevent WNV infection. Hear’s a complete guide:
Use Insect Repellent: Apply insect repellent containing DEET, icaridin, or oil of lemon eucalyptus to exposed skin and clothing.Follow the manufacturer’s instructions carefully.
Wear protective Clothing: When outdoors,wear long-sleeved shirts,long pants,and socks,especially during dawn and dusk when mosquitoes are most active. Light-colored clothing is also recommended.
Eliminate Standing Water: Mosquitoes breed in standing water.Regularly empty and clean items that collect water, such as:
Flower pots
Bird baths
Gutters
Old tires
Children’s toys
Screen Your Home: Ensure windows and doors have tight-fitting screens to keep mosquitoes out. Repair any holes or tears in screens.
mosquito Nets: Use mosquito nets when sleeping outdoors or in unscreened areas.
West Nile Virus and Vulnerable Populations
Certain groups are at higher risk of developing severe illness from WNV:
Seniors: Individuals over 60 years of age.
Individuals with Compromised immune Systems: People with conditions like HIV/AIDS, cancer, or those taking immunosuppressant medications.
Individuals with Chronic Medical Conditions: Those with diabetes, heart disease, or kidney disease.
These individuals shoudl be particularly diligent about taking preventative measures.
Reporting Mosquito Breeding Sites
Residents of Whitby and durham Region can help control the mosquito population by reporting potential breeding sites to the Durham Region Health Department. This includes stagnant water in neglected properties or public spaces. Contact information can be found on the Durham Region Health department website (https://www.durham.ca/en/health-and-wellness/west-nile-virus.asp).
Understanding Mosquito Habitats: A Geographic Viewpoint
While the provided search result touches on directional terms like “west of,” it’s important to understand that mosquito habitats aren’t limited by geography. They thrive wherever standing water exists, regardless of direction. Though, areas with more wetlands, wooded areas, and agricultural land frequently enough support larger mosquito populations. The Durham Region, with its mix of urban and rural environments, presents varied mosquito habitats.
