Upper Respiratory Infection
An upper respiratory infection affects the nose, throat, and upper airways. Most cases are viral and improve with time and supportive care.
Symptoms
Symptoms often include congestion, runny nose, sore throat, cough, sneezing, fatigue, and low-grade fever.
Causes and risk
Viruses spread through close contact, droplets, and contaminated hands.
How it is evaluated
We review the pattern of symptoms, check for breathing issues, and look for signs of strep throat, sinusitis, pneumonia, or influenza when needed.
Treatment
Treatment usually includes rest, fluids, symptom relief, and clear return precautions. Antibiotics do not help viral infections.
