The common cold is an infection caused by a group of viruses known as rhinoviruses. These viruses infect the upper respiratory tract, including the nose, throat, and sinuses.

The symptoms of a cold may include coughing, sneezing, a runny or stuffy nose, sore throat, and general feelings of malaise. While colds are often mild and self-limited, they can be more severe in some individuals, and they can lead to complications, particularly in people with weakened immune systems.

How is the common cold spread?

The common cold is transmitted from person to person through droplets of mucus or saliva. These droplets are released when infected people cough, sneeze, or talk, and they can land on surfaces or be directly inhaled by others.

The virus can also be picked up when people touch the surfaces on which these droplets have landed and then touch their nose, mouth, or eyes.

Although the virus can be spread almost anywhere, it is more commonly transmitted in places where people are in close quarters, such as schools, daycare centers, and offices.
