The common cold, in most cases, causes a runny nose, nasal congestion, and sneezing, although a sore throat, headache, cough, and watery eyes are also possible.
Of the various respiratory viruses, rhinoviruses are the most common source. The cold virus enters your body through your mouth, eyes, or nose. It can spread through airborne droplets when someone who is sick coughs, sneezes, or talks. It is also spread by hand contact with someone who has had a cold or by sharing contaminated items, such as utensils, towels, toys, or telephones.
If you touch your eyes, nose, or mouth after you have had contact with the virus or have been exposed, you may catch a cold. Colds can occur at any time of the year but are more common during the winter or rainy season. Common cold symptoms may last longer in people who smoke.
They usually begin two to three days after exposure to the virus that causes the cold, although they may take up to a week afterward. The most common signs and symptoms (which may vary from person to person) are nasal congestion, rhinorrhea (runny nose), coughing, sneezing, coughing, decreased appetite, mild headache, mild muscle aches, postnasal drip, sore throat.
Adults and older children with colds usually have a low fever or no fever. Young children often have a fever of about 37.7°C to 38.8°C. People are most contagious during the first 2 to 3 days of a cold.
Difference between cold and flu
A diagnosed cold caused by a specific virus cannot "mutate" into the flu. Cold symptoms are mild. Cold symptoms tend to appear gradually. The flu is caused by different types of viruses than those that cause the common cold. Flu symptoms tend to be stronger. Symptoms tend to come on suddenly. When you have the flu you will usually have a fever, chills, and aching muscles and joints.
You can catch one when a person with a cold sneeze, coughs, or blows his or her nose near you, touches your nose, eyes, or mouth after contact with the virus, such as a toy or a door jamb. Although most colds go away in a few days, there are some steps you can take to take care of yourself.
