Knowing the Difference Between Cold and Flu Symptoms

The winter months are often associated with an increase in illnesses, particularly the common cold and seasonal influenza. These conditions can impact any workplace and spread quickly, leaving you and your co-workers with debilitating symptoms.

Though the common cold and seasonal influenza share several symptoms, there are points of differentiation that will help you identify which you may have in order to seek proper treatment. It is essential to distinguish between the two, as the flu can lead to more severe health complications, whereas the cold is generally less serious.

Common Cold Symptoms

Typically, symptoms of the common cold develop gradually, often starting with a sore throat or irritated sinuses. The most common symptoms of a cold are nasal congestion, sneezing, and a runny nose. Symptoms can also include a cough, mild headache, and minor body aches.

People are generally contagious during the first three days they have a cold. Symptoms typically subside within a week.

Seasonal Flu Symptoms

Unlike the common cold, flu symptoms usually come on suddenly and vigorously, often starting with a high-grade fever, headache, body aches, and fatigue. In addition, flu symptoms can include a dry cough, sore throat, and sometimes a runny or stuffy nose.

Symptoms are generally more severe than with a cold. Flu symptoms tend to gradually improve after two to five days, but can last for a week or more. You should stay home for at least 24 hours after your fever is gone to avoid passing your illness to others.

Prevention

Some strategies can help you avoid contracting either of these conditions. These include frequent hand washing, sanitizing commonly touched surfaces, and avoiding touching your eyes, nose, and mouth. If you are sick, cough and sneeze into your elbow to prevent the spread of germs to others.

Treatment

For the common cold, a doctor visit is usually unnecessary. Over-the-counter medications can be effective in treating symptoms. For the flu, a doctor may prescribe antiviral medications that can help decrease the severity and duration of symptoms.

Potentially serious health complications can occur in people suffering from the flu. Call your doctor if you think your symptoms are worsening or if you have a condition such as asthma, diabetes, or are pregnant.

Safety First

Knowing the difference between the common cold and seasonal flu can help you better determine when it’s best to stay home from work and seek medical care. In doing so, you can protect yourself and minimize the spread of illness in the workplace, ultimately keeping everyone healthy and safe.
