A cold is a self-limiting viral infection most commonly caused by Rhinovirus

The common cold is a self-limiting upper respiratory tract infection, meaning it typically resolves without specific medical treatment. It is most commonly caused by rhinoviruses, which are highly contagious and spread through respiratory droplets and contact with contaminated surfaces. Symptoms such as nasal congestion, sore throat, cough, and mild fever usually resolve within 7 to 10 days as the immune system clears the virus. Management is primarily supportive, including rest, hydration, and symptom relief, rather than antiviral therapy.
