Colds & Flu
Colds & Flu
Colds and the flu are illnesses that are caused by viruses. Colds can be caused by many different viruses which is part of the reason why they are so common. Flu is also caused by a virus. The flu virus mutates quickly which is why it’s recommended to get a flu shot every year. Each year, scientist evaluate last years flu virus and try to predict how it will mutate so that they can develop next years shot.
Colds and the flu can have very similar symptoms. Both can cause a sore throat, runny nose and cough, however, the flu is much more severe.
Cold symptoms usually last about a week. For the first 3 days or so you are contagious and can spread the cold virus to others, so washing your hands frequently and using tissues while sneezing or coughing can help reduce the chance of you passing the virus on. A cold usually starts with a sore throat which usually goes away after the second day. Nasal symptoms and congestion usually follow, along with a cough. Fever is not common in adults with colds, however, children are more likely to run a fever with a cold. It is easy to confuse a cold with allergies or a sinus infection. If your symptoms begin quickly and are improving after a week, chances are that you have a cold, but if your symptoms continue, schedule an appointment with your doctor to see if you may have developed an allergy.
