What to tell us about your symptoms

Cough, sore throat, fever, fatigue and body aches can overlap across respiratory illnesses. The timing, severity and your health history help guide the conversation.

What the video visit can help with

Explain when you first felt ill, what has changed and what you have already tried. Bring up any breathing concerns and conditions that may raise your risk of complications. Our physicians and nurse practitioners can discuss symptom care and whether testing or an examination is the better next step.

When an examination or testing may be needed

A flu or COVID-19 test may help clarify the cause. Symptoms alone do not always tell these illnesses apart. A clinician can explain whether testing would change your care.

Discussing treatment

Flu treatment may include antiviral medicine for an eligible patient, particularly when assessed early. Antibiotics do not treat the flu. Treatment recommendations and any prescription depend on the clinical evaluation.

When to get care in person

Get emergency help for severe trouble breathing, persistent chest pain or pressure, new confusion or inability to stay awake. Do not put off urgent care to finish an online booking.

Before your visit

Write down the first day of symptoms, recent test results and the names of medicines you have taken. This gives the clinician a clearer timeline without making you retell everything from memory.

Questions about this care

Can a video visit help me decide whether this is the flu?

It can help you discuss the pattern of symptoms and the need for a test. It does not make a flu diagnosis certain from symptoms alone.
