The cold and flu are both respiratory illnesses, but are they the same? Usually, people confuse a cold with the flu because of the similar symptoms. This article will explain the distinction between a cold and the flu.
Influenza (flu) and the common cold are both contagious respiratory illnesses, but they are caused by different viruses. Flu is caused by influenza viruses only, whereas the common cold can be caused by a number of different viruses, including rhinoviruses, parainfluenza, and seasonal coronaviruses. (Seasonal coronaviruses should not be confused with SARS-CoV-2, the virus that causes COVID-19).
Because flu and the common cold have similar symptoms, it can be difficult to tell the difference between them based on symptoms alone. In general, flu is worse than the common cold, and symptoms are typically more intense and begin more abruptly.
Colds are usually milder than flu. In fact, more than 200 different types of viruses can cause a cold. The most common cold virus is the rhinovirus.
We call colds “common” because as their name implies, they’re widespread. You’ll probably have more colds in your lifetime than any other illness. Adults catch two to three colds a year, while young children come down with a cold four or more times a year.
People with colds are more likely to have a runny or stuffy nose than people who have flu. Colds generally do not result in serious health problems, such as pneumonia, bacterial infections, or hospitalizations.
Flu on the other hand, can have serious associated complications. Because colds and flu share many symptoms, it can be difficult (or even impossible) to tell the difference between them based on symptoms alone. Special tests can tell if a person is sick with flu.
Symptoms of cold easily spread from person to person. For you to become infected, the virus has to get to one of your mucous membranes that’s the moist lining of your nostrils, eyes or mouth. That happens when you touch a surface or breathe moist air that contains the cold virus.
The symptoms of flu can include fever or feeling feverish/chills, cough, sore throat, runny or stuffy nose, muscle or body aches, headaches, and fatigue (tiredness). Cold symptoms are usually milder than the symptoms of flu. People with colds are more likely to have a runny or stuffy nose. Colds generally do not result in serious health problems.
There’s no cure for a cold. You have to let it run its course. Most colds go away on their own within seven to 10 days and don’t turn into anything more serious. Common cold treatment includes over-the-counter (OTC) medications to help reduce your symptoms and keep you comfortable until you recover.
