RSV vs. flu: How to tell the difference

As colder months approach, medical experts are clarifying distinctions between Respiratory Syncytial Virus and influenza, as both contagious illnesses circulate heavily during fall and winter seasons.
While both viruses share respiratory symptoms, they are caused by different pathogens requiring distinct treatment approaches. Influenza typically strikes suddenly with high fever and severe body aches, whereas RSV symptoms appear more gradually.
High-Risk groups include children under 5, particularly infants under 2, and adults over 65. Those with chronic health conditions face increased danger from both RSV and influenza infections.
Testing via nasal or throat swabs can confirm the specific virus, enabling targeted care. While supportive care like hydration manages both infections, antiviral medications are available for influenza if started early.
Preventive measures remain the most effective strategy, including frequent hand washing and avoiding crowded spaces. Annual flu vaccination is recommended for eligible individuals to provide the best protection against current strains.
