Do I Have COVID-19, the Flu, or RSV? Understanding Your Symptoms

Feeling feverish or exhausted? With multiple respiratory viruses on the rise in the UK, it’s harder than ever to tell them apart. COVID-19, flu, and RSV can look and feel very similar—so making the right decision for your health means knowing the differences and similarities.

What Are the Common Symptoms?

Symptoms often overlap. If you’re in the UK and not sure what’s causing your illness, you’re not alone. Treatment and risks differ—so does the advice about isolation and contact with others. Find NHS advice here.

The Science: Why Combination PCR Testing?

Our At-Home Respiratory PCR Panel Test checks for all three viruses at once, using a painless self-swab. PCR technology identifies viral genetic material, providing accurate answers to help inform your next steps—whether that’s staying home, seeking treatment, or returning to normal activity.

What If You Don’t Need a Test?

Empower Yourself with Clarity

Don’t let uncertainty keep you from getting the right care. Order your at-home respiratory PCR panel or book an in-person consultation at Mayfield Clinic for rapid reassurance.
