Greg and Dan talk to Dr. Brian Curtis of OSF HealthCare about the current flu virus circulating at very high levels across Illinois, including a new strain that’s contributing to the surge. He explains both old and new prevention methods, when it’s safe to return to work after being sick, and why staying home while symptomatic is critical. Dr. Curtis also discusses rising COVID rates (up 20–30%), the possibility of having both flu and COVID at the same time, and explains what MRSA is and how it spreads.
