upper respiratory infections
Upper respiratory infections (URIs) affect the nose, throat, and sinuses, commonly caused by viruses like the common cold or influenza. They spread through airborne droplets or contact with contaminated surfaces. Symptoms include a runny or stuffy nose, sore throat, cough, sneezing, and sometimes fever or body aches. Most URIs are self-limited, lasting about a week, and are usually managed with rest, fluids, and over-the-counter remedies. While generally mild, they can sometimes lead to complications or secondary infections. Good hygiene practices, like handwashing, can help prevent their spread.
