Common colds can be caused by a variety of viruses, but rhinoviruses are the most common. Cold viruses enter a person’s body through their mouth, eyes, or nose. When sick people cough, sneeze or talk, the virus can spread through droplets in the air. Hand-to-hand contact with a person with a cold or sharing contaminated objects, such as eating utensils, towels, toys, or telephones, can also spread the virus. You are likely to catch a cold, according to healthcare professionals, if you touch your eyes, nose, or mouth after such contact. Colds and flu are often confused by people. While they are different, some of the symptoms may be the same. It is common for people to get cold several times a year. Flu generally occurs only once every few years, on the other hand. Influenza viruses cause the flu. A person usually gets the flu by breathing in tiny airborne droplets from someone else's cough or sneeze. It is also possible to catch the flu by touching something with the virus on it and then touching your mouth, nose, or eyes.
