Ottawa Public Health has issued a formal declaration that the city, and the broader region, has entered the annual influenza season. The announcement was made on December 5, 2025, marking a predictable yet critical period for the healthcare system.
Virus Activity on the Rise Across the Province
Alongside the official start of flu season, new data indicates a concurrent increase in cases of Respiratory Syncytial Virus, commonly known as RSV. This virus, which can cause severe respiratory illness in young children and older adults, is showing heightened activity levels throughout Ontario. The dual rise of influenza and RSV signals a challenging period for public health officials and hospitals, which often see increased admissions during this time.
The declaration by Ottawa Public Health serves as a key reminder for residents to take preventive measures seriously. Health authorities consistently emphasize that vaccination remains the most effective tool against severe influenza outcomes.
Protecting Yourself and Your Community
With the season now underway, public health officials are urging several key actions. Getting an annual flu shot is highly recommended for everyone aged six months and older. Frequent hand washing, covering coughs and sneezes, and staying home when feeling unwell are fundamental practices to slow the spread of both influenza and RSV.
Monitoring for symptoms is also crucial. Typical flu signs include the sudden onset of fever, cough, muscle aches, and fatigue. RSV often presents as a runny nose, decrease in appetite, coughing, sneezing, and wheezing. Parents of infants and individuals with underlying health conditions are advised to be particularly vigilant.
A Coordinated Public Health Response
The proactive announcement from Ottawa's health unit is part of a broader strategy to manage seasonal virus surges. By clearly communicating the season's start, they aim to prompt higher vaccine uptake and public awareness before infection rates peak. This coordinated approach is essential for reducing the strain on healthcare resources and protecting vulnerable populations across the community.
As the winter months progress, Ottawa Public Health will continue to monitor laboratory confirmations, hospitalizations, and outbreaks in institutions like long-term care homes to track the severity and progression of the season.
