Summer colds can also be contagious. Colds in the summer are usually viral colds, which are generally contagious. Viral colds often involve viruses such as rhinoviruses, adenoviruses, respiratory syncytial viruses, human metapneumoviruses, and coronaviruses, all of which are contagious. Therefore, it is necessary to take preventive measures against summer colds to prevent the spread to family members, such as maintaining a certain social distance, and covering your mouth and nose with an arm or tissue when coughing to reduce the spread of viral droplets. These practices help prevent the transmission of colds. Additionally, washing hands frequently and paying attention to hand hygiene also aid in preventing the spread of colds.
