When Flu, Norovirus, COVID-19 and the Common Cold Collide: Introducing "Flunorococo" Season This Winter

During the winter illness surge, Lysol Disinfectant Spray helps reduce the spread of illness-causing germs circulating in schools, workplaces and communities
NUTLEY, N.J., FEBRUARY 17, 2026 – Each winter, communities nationwide face a surge of four main viruses that cause infections and disrupt consumers' daily lives: Influenza, Norovirus, COVID-19 and the Common Cold. Lysol calls this peak period of overlapping winter illnesses "Flunorococoseason" – and during this time, everyday cleaning routines are not enough to protect against the spread of illness-causing germs brought into the home.
What is Flunorococo Season?
"Flunorococo" describes the simultaneous circulation of four major illnesses: • FLU (Influenza) • NORO (Norovirus) • CO (COVID-19) • CO (Common Cold)
Lysol Disinfectant Spray
With the ongoing severity of winter illnesses, consumers can take measures to help protect themselves and their families by using Lysol Disinfectant Spray, which provides proven surface germ protection against these viruses and, when used as directed, is 3x more effective at stopping the spread of germs on surfaces (vs. cleaning alone)*.
"Following the COVID-19 pandemic, consumers have largely returned to their everyday cleaning routines, only disinfecting reactively when illness or exposure occurs," said Callum Couser, R&D Senior Manager, Aerosols Innovation at Reckitt.
"However, when used as directed, proactive disinfection with Lysol Disinfectant Spray is crucial to kill 99.9% of viruses and bacteria on surfaces and to help support protection from the spread of illness-causing germs this winter, including the flu, norovirus, COVID-19 and the common cold, in the home."

In May 2025, Lysol conducted a germ transmission study with the University of Arizona and found that targeted use of Lysol Disinfectant Spray on high-touch surfaces can dramatically reduce the spread of germs in the home. Dr. Kelly Reynolds, Principal Investigator within the University of Arizona study, also noted that "for an average family of four, disinfecting frequently touched surfaces can help prevent up to three colds per year.**"
Families can make proactive disinfection a part of their everyday routine with Lysol Disinfectant Spray and, when used as directed, help prevent the spread of illness-causing germs. VisitLysol.comand follow @Lysolon Instagram and @LysolUSon TikTok to learn more.
