The influenza epidemic in Belgium has officially ended, according to figures released by the Sciensano health institute. The epidemic, which lasted approximately three months, prompted the implementation of a code orange alert in January and February to curb the spread of the virus. While concerns about a particularly severe “super flu” circulated earlier in the season, the outbreak ultimately followed a more typical pattern, though it did place significant strain on the healthcare system.
The peak of the epidemic saw a more than doubling of consultations for flu-like symptoms with general practitioners compared to the beginning of January, reaching 676 per 100,000 inhabitants during the week of January 19th to 25th. Wastewater testing likewise indicated a strong circulation of respiratory infections. Sciensano data revealed that influenza and Respiratory Syncytial Virus (RSV) were the predominant viruses circulating, while COVID-19 remained at a low level. Hospital admissions for severe acute respiratory infections also increased, reaching 23.9 per 100,000 inhabitants, exceeding the threshold for a red alert on the Respi-Radar, Sciensano’s warning tool.
Code Orange Measures and Healthcare Strain
Two weeks ago, the Risk Management Group (RMG) of the Federal Public Service Health elevated the general warning level for respiratory infections to code orange, a designation that remains in effect. This code signifies considerable pressure on the healthcare system. Under code orange guidelines, individuals experiencing illness are urged to stay home and those with mild symptoms are recommended to wear a face mask in crowded places, when in contact with vulnerable individuals, and during all interactions with healthcare personnel for at least five days after the onset of symptoms.
The Respi-Radar, a crucial tool for monitoring respiratory illness trends, had already surpassed the threshold for the highest warning level, code red, for specific indicators. This indicated a particularly high level of risk, prompting the heightened alert status. The implementation of code orange measures aimed to mitigate the burden on hospitals and ensure continued access to care for those most in need.
Flu Season Trends and Comparisons
While the recent epidemic has concluded, understanding seasonal influenza trends is vital for public health preparedness. Sciensano provides detailed figures and statistics on influenza, including its intensity, severity, and impact on the population. These data are essential for tracking the evolution of the virus and informing future vaccination campaigns and public health interventions.
Reports from late January 2026 indicated that the flu continued to circulate actively, with hospitalizations for severe respiratory infections on the rise. The increase in consultations with general practitioners for flu-like symptoms underscored the widespread nature of the outbreak. The situation prompted a renewed emphasis on preventative measures, such as vaccination and adherence to hygiene protocols.
Looking Ahead and Continued Vigilance
The end of the official epidemic does not signify a complete absence of influenza. The virus is expected to continue circulating at lower levels, and sporadic cases may still occur. Public health officials emphasize the importance of maintaining vigilance and continuing to practice good hygiene, such as frequent handwashing and covering coughs and sneezes.
The experience of this flu season highlights the ongoing need for robust surveillance systems and proactive public health measures to protect the population from respiratory infections. Sciensano will continue to monitor the situation closely and provide regular updates on influenza activity. Individuals are encouraged to stay informed about the latest recommendations and to consult with their healthcare provider if they experience flu-like symptoms.
As we move forward, continued monitoring of respiratory viruses and adherence to preventative measures remain crucial. The next official update from Sciensano regarding respiratory illness trends is expected in early April.
