Key Takeaways
Key Indicator
Shortness of breath, chest pressure, and loss of taste/smell are key markers for COVID-19 and are rarely caused by the flu.
Speed of Onset
Flu symptoms tend to hit all at once like a "wall," whereas COVID-19 symptoms often develop slowly over a few days.
When Feeling Sick
Stay home, isolate from high-risk individuals, and contact your PharmaChoice pharmacist if you need advice on managing symptoms.
How to Reduce Your Risk
Get Vaccinated
An annual flu shot and COVID-19 vaccine significantly lower your risk of severe illness and help protect vulnerable family and community members.
Wash Hands Frequently
Scrub hands with soap and warm water for at least 20 seconds after being in public spaces, or use an alcohol-based hand sanitizer when soap isn't available.
Support Your Immunity
Keep your immune system strong through balanced nutrition, daily movement, adequate sleep, and staying hydrated throughout the day.
