Respiratory illnesses can sometimes look very similar at the beginning.
Influenza, COVID-19 and RSV may share symptoms such as cough, fever, sore throat, runny or stuffy nose, headache and fatigue. Because these symptoms can overlap, it may not be possible to identify the cause based on symptoms alone.
A healthcare professional can advise whether assessment or testing is appropriate based on the person’s symptoms, health risks and clinical situation. Appropriate testing may help distinguish between respiratory infections and support the next steps in care.
Seek prompt medical attention when symptoms are severe or worsening, especially when there is difficulty breathing, chest pain or pressure, confusion, difficulty drinking enough fluids, or other concerning changes.
Similar symptoms may have different causes. Responsible assessment matters.
