Common Cold or Influenza?
Common Cold or Influenza?
It is important to know that more than 200 different viruses can cause the common cold. Influenza, on the other hand, is primarily caused by two major types of influenza viruses that infect humans.
At first glance, the common cold and influenza may appear very similar. Both are respiratory illnesses and can produce many of the same symptoms. However, they are caused by different viruses, and the severity and pattern of symptoms can help distinguish one from the other.
Both illnesses commonly cause a runny nose, sneezing, body aches, and fatigue.
What Is the Difference Between a Common Cold and Influenza?
Influenza differs significantly from the common cold. In general, influenza symptoms are more severe, and people with influenza usually remain ill and confined to bed for a longer period.
The common cold is typically milder, whereas influenza often begins suddenly with a high fever and severe fatigue, making the illness much more debilitating.
People with a common cold usually experience fatigue along with sneezing, coughing, and a runny nose. Fever is often absent or only mild. In contrast, influenza commonly causes extreme weakness and fatigue, high fever, dry cough, runny nose, chills, muscle aches, severe headache, eye pain, and sore throat.
Another important difference is that influenza is more likely to lead to complications such as sinus infections, ear infections, and lower respiratory tract infections.
If a physician diagnoses a common cold, treatment generally focuses on rest, drinking plenty of fluids, and relieving symptoms while the body recovers naturally. If influenza is diagnosed, antiviral medications may be prescribed, particularly when treatment begins early. Adequate rest and hydration are also essential to help reduce symptoms and support recovery.
Factors That Increase the Risk of Illness
Age: Young children and older adults are more likely to develop colds and influenza because their immune systems are either not fully developed or have become less effective with age.
Lack of Sleep and Stress: Insufficient sleep and chronic stress weaken the immune system, making the body more vulnerable to viral infections.
Tobacco Use: Smoking cigarettes or using hookah increases the risk of respiratory infections for both smokers and those exposed to secondhand smoke by weakening the body’s natural immune defenses.
Allergies: Allergies and the common cold share several symptoms, such as a sore throat and a runny nose. Because allergies can irritate the lining of the nose and throat, they may increase susceptibility to respiratory infections, including the common cold and influenza.
