Сократить текст Common Cold (Acute upper respiratory infection) The common cold is our most ubiquitous illness. On average, adults have two to four colds a year, and some children have 8 to 12. People, who work in schools or health care settings, or who have small children, are more likely to catch multiple colds each year. Symptoms may vary, but the typical cold starts with a sore throat, sneezing, nasal congestion, and a runny nose, frequently followed by a cough that can linger for a week to 10 days. More than 200 different viruses can cause cold symptoms, but the most common are in the rhinovirus family and are highly contagious. They are often transmitted through the air when someone who has a cold expels them by sneezing or coughing and someone else inhales them. They can also travel from one person to another by direct contact with fingers, tissues, or other objects that can harbor a virus. Even though so many different viruses are involved, they all produce similar symptoms, which is why all are classified as a single illness. Colds can occur at any time of the year, but are most common in the late fall, winter, and early spring.
