Have you got a cold recently? Common cold is no stranger to perhaps all of us. It can be a result of viral infection, most commonly rhinoviruses, and it is contagious through hand-to-hand contact and sharing objects with an affected person.
Details about common cold: viral infection
The common cold is a viral infection of your nose and throat (upper respiratory tract). It's usually harmless, although it might not feel that way. Many types of viruses can cause a common cold.
Children younger than six are at greatest risk of colds, but healthy adults can also expect to have two or three colds annually.
Most people recover from a cold in a week or 10 days. Symptoms might last longer in people who smoke. If symptoms don't improve, see your doctor.
Causes of common cold: rhinoviruses
Although many types of viruses can cause the disease, rhinoviruses are the most common culprit.
A cold virus enters your body through your mouth, eyes or nose. The virus can spread through droplets in the air when someone who is sick coughs, sneezes or talks. It also spreads by hand-to-hand contact with someone who has a cold or by sharing contaminated objects, such as utensils, towels, toys or telephones. If you touch your eyes, nose or mouth after such contact or exposure, you're likely to catch a cold.
