What pathogens causes the common cold?

The common cold is primarily caused by viruses, with rhinoviruses being the most prevalent culprits. Other pathogens that can lead to cold symptoms include coronaviruses, adenoviruses, and respiratory syncytial virus (RSV). These viruses infect the upper respiratory tract, leading to symptoms such as a runny nose, sore throat, and cough. The cold is highly contagious, typically spreading through respiratory droplets or direct contact with contaminated surfaces.
