user
The common cold is caused by viruses, most commonly rhinoviruses. Other viruses that can cause colds include coronaviruses, respiratory syncytial virus (RSV), and adenoviruses. These viruses spread through the air via droplets when an infected person coughs, sneezes, or talks, or through direct contact with contaminated surfaces or objects.
