Seek medical care immediately if the person develops any of the following symptoms:
• Fast breathing, trouble breathing or bluish skin color.
• Pain or pressure in the chest or abdomen (adults).
• Confusion or sudden dizziness.
• Not drinking enough fluids, not being able to eat, or severe or persistent vomiting.
• Flu-like symptoms that improve, but then return with fever and worse cough.
• Not waking up, being so irritable that the child does not want to be held or not interacting (children).
• Fever with a rash (children).
• No tears when crying or significantly fewer wet diapers than normal (children).
