The common cold, also known as a viral upper respiratory tract infection, is a prevalent illness characterized by symptoms such as a runny or stuffy nose, sore throat, coughing, sneezing, and mild fatigue. It is primarily caused by rhinoviruses, though other viruses such as coronaviruses, adenoviruses, and respiratory syncytial virus (RSV) can also contribute to colds. The common cold spreads through respiratory droplets when an infected person coughs or sneezes, or through direct contact with contaminated surfaces. While typically not serious, the common cold can be bothersome and disruptive to daily life. Treatment focuses on managing symptoms and supporting the body’s immune response. This may include getting plenty of rest, staying hydrated, using over-the-counter medications such as decongestants or pain relievers to alleviate symptoms, and practicing good hygiene to prevent the spread of the virus to others. In most cases, symptoms of the common cold resolve within a week or two without complications. However, certain individuals, such as young children, older adults, and those with weakened immune systems, may be at risk of developing more severe complications, such as sinusitis or pneumonia, and should seek medical attention if symptoms worsen or persist.
