Flu, COVID-19, or RSV: When to Take Care and Seek Help
Current, practical guidance for navigating respiratory-virus symptoms without trying to diagnose yourself at home.
Cold, flu, COVID-19, and RSV symptoms can overlap. A runny nose, cough, fatigue, fever, or sore throat can happen with more than one illness, so a symptom list alone cannot reliably identify the cause.
This refreshed article replaces older, time-sensitive advice with a simpler approach: notice symptoms, use testing and local guidance when appropriate, protect people around you, and get medical help promptly when warning signs appear.
What you can do at home
Rest, fluids, and symptom relief that is appropriate for you are often the first steps for a mild respiratory illness. Stay home and away from others when you are feverish or feel too unwell for normal activities. Good hand hygiene and fresh air can also reduce spread at home.
If COVID-19 testing is available to you, it can be useful because treatment may matter for people at higher risk. A clinician or pharmacist can help with questions about testing, medications, and interactions.
When to seek urgent care
Seek emergency help for trouble breathing, persistent chest pain or pressure, new confusion, inability to stay awake, blue or gray lips or face, or other severe symptoms. Infants, older adults, pregnant people, and people with chronic lung, heart, or immune conditions may need earlier clinical advice.
Do not wait for a perfect diagnosis if symptoms are concerning. A qualified clinician can help determine the right next step.
Protecting other people
Avoid close contact when ill, cover coughs and sneezes, wash hands, and consider a well-fitting mask around others when respiratory symptoms are present. Keep vaccinations current according to your clinician and local public-health guidance, especially if you are at increased risk of severe illness.

Frequently asked questions
Can symptoms tell me which virus I have?
Not reliably. Flu, COVID-19, RSV, and common colds can look similar. Testing and clinical guidance are more dependable than guessing from symptoms.
When should I call a clinician?
Call promptly for worsening symptoms, a high-risk medical condition, pregnancy, concern about an infant or older adult, or questions about treatment options.
