What is a Cold?
The common cold is a viral infection that primarily affects the nose and throat. It is usually harmless, although it may not feel that way when you are experiencing it. The common culprits for causing a cold are rhinoviruses, but it can also be caused by over 200 different viruses.
Colds are more frequent in the fall and winter months, although they can occur at any time of the year. The symptoms usually begin two to three days after exposure to the virus and can include a runny nose, sore throat, cough, congestion, slight body aches, mild headache, sneezing, and low-grade fever. While there is no cure for the common cold, symptoms typically subside within a week to ten days.
What is the Flu?
The flu, or influenza, is a contagious respiratory illness caused by the influenza viruses that infect the nose, throat, and sometimes the lungs. Unlike the common cold, the flu can lead to serious complications such as pneumonia, especially in young children, older adults, and individuals with underlying health conditions.
Influenza is more severe than a cold and comes on suddenly. The symptoms include high fever, chills, muscle aches, severe fatigue, weakness, chest discomfort, and a dry cough. In some cases, nausea, vomiting, and diarrhea may occur, especially in children. Flu season typically peaks during the winter months, and the best preventive measure is an annual flu vaccine.
