The recent surge in respiratory viruses, including COVID-19, RSV, and influenza, has caused concerns globally. The increased number of respiratory illness cases during the summer of 2022, when rates are typically low, is unusual, and the current winter is expected to have a significant impact on healthcare systems and populations. The surge may be due to a combination of reduced COVID-19 mitigation efforts and immunity debt resulting from prolonged periods without infection. Getting vaccinated and continuing to take precautions such as frequent hand washing, using masks in enclosed spaces, and avoiding contact with others while unwell with respiratory viruses can help protect against these illnesses. Collecting and sharing surveillance data will help improve prevention and control strategies, and early antiviral therapies and prophylaxis are recommended for those at risk of severe illness. By staying alert and adhering to guidelines, we can successfully navigate this atypical winter surge. Diligence and compliance with expert advice will help us triumph over this unexpected increase.
