A Viral Cocktail
More than 200 virus types can cause the common cold, with rhinoviruses being the most prevalent culprits, responsible for 30-50% of cases. Other viruses like coronaviruses and adenoviruses also play a role. New technologies continue to identify even more cold-causing viruses, reflecting the complexity of this condition.
Symptoms and Their Cause
The symptoms of a cold, such as a runny nose, sore throat, and cough, are largely due to the body's immune response rather than the virus itself. These symptoms vary by individual factors like age and existing health conditions. Usually, adults don't experience fever with a cold, but children might.
The Spread of the Cold
Cold viruses spread through hand contact, airborne droplets, and contaminated surfaces. The viruses can survive on skin for hours, making hand-to-hand transmission significant. Simple hygiene practices can help reduce the spread, although factors like recirculated air in airplanes are less impactful than once believed.
