Flu Cases Drop but Respiratory Viruses Still Circulating in Luxembourg

Luxembourg’s health authorities reported a noticeable decline in influenza infections during the week of 19–25 January 2026, with lab-confirmed flu cases dropping from 872 to 740 – a decrease of about 15 % compared with the previous week. This marks the second consecutive week of decline, suggesting that the peak of the flu season may have passed. 

Despite the drop, officials emphasised that flu activity remains high in the community, and the virus continues to circulate widely across the country. Health authorities are urging people, especially those at higher risk, to remain vigilant.

In addition to influenza, the respiratory syncytial virus (RSV) also showed a modest decrease in the same period, with confirmed cases falling by around 14 % from the previous week. Most RSV infections were reported among young children, indicating that the virus continues to pose risks to younger age groups. 

By contrast, COVID-19 cases increased, rising from 65 to 88 confirmed infections during the week. Although overall numbers remain relatively low, the increase highlights ongoing transmission of the coronavirus alongside other respiratory pathogens. 

Health officials continue to recommend vaccination for influenza, particularly for people aged 65 and over, and encourage simple preventive measures like hand hygiene and staying home when sick to reduce the spread of respiratory viruses.
