Symptom Overlap: COVID-19, Flu, or RSV? How to Choose the Right Next Step

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?

• COVID-19: Fever, cough, loss of taste/smell, sore throat, headaches, tiredness
• Flu: Sudden fever, chills, body aches, sore throat, cough, fatigue
• RSV: Runny nose, dry cough, difficulty breathing, especially in children and older adults

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?

• Rest and recover at home
• Drink fluids and monitor your temperature
• Avoid contact with high-risk individuals if you have symptoms
• Check the latest NHS COVID-19 advice
• Contact your GP if symptoms worsen or if you’re at risk of complications
