matters needing attention

Many people think that a cold is transmitted by inhaling the gas from a patient. In fact, contact transmission is also the main route of transmission of cold. When a cold patient touches his nose, his hands will be infected with cold virus. These viruses will be brought to the places where the patient contacts, such as doorknobs, telephones, desks and chairs, and car armrests. Once the hands of healthy people touch these contaminated objects, they will be infected with virus. If they don't wash their hands often, they will easily catch a cold.
