My brother, 18, has the flu. When should we visit the ER?

Question

Hello doctor,

My younger brother, who is 18, currently has flu-like symptoms, including fever, cough, and body aches, but we are unsure how serious it is. I have been wondering what symptoms in someone his age should prompt an immediate visit to the emergency room for flu, as we do not want to overreact, but also do not want to delay care if it could be serious.

He seems quite tired and has occasional shortness of breath, which is a bit concerning for us. Are there clear warning signs we should watch for before deciding to go to the hospital?

Please suggest.

Thank you.

Hello,

Welcome to icliniq.com.

I have read your query and understand your concern.

It makes sense to be cautious here, especially when you are seeing symptoms that feel a bit beyond a routine illness. With influenza (a respiratory disease caused by the influenza virus), most young people recover at home, but there are clear warning signs that should prompt an immediate visit to the emergency room.

Shortness of breath is one of the most important red flags, especially if it is noticeable at rest, worsening, or making it hard for him to speak in full sentences. That alone is enough to take seriously rather than wait and see.

Other urgent signs include chest pain or pressure, bluish lips or face, confusion or unusual drowsiness, difficulty staying awake, a very high fever or one that returns after improving, severe dehydration (such as very little urination or dizziness when standing), or coughing up blood. Extreme weakness that makes it hard to stand or walk normally can also be concerning.

If his breathing seems even mildly compromised, or if you feel unsure, it is safer to get him checked promptly rather than risk deterioration at home. If symptoms are milder, supportive care such as fluids, rest, and fever control is usually enough.

However, given that you mentioned shortness of breath, it would be reasonable to err on the side of caution and have him evaluated sooner rather than later.

Hope I have addressed all of your queries and concerns.

Do follow up whenever needed.

Thank you.
