1. What Causes Flu & Common Cold?
The flu (influenza) and common cold are caused by viruses. Winter provides the perfect environment for viruses to spread quickly because:
-
People stay indoors
-
Air is dry
-
Immune system becomes weaker
These infections spread through cough droplets, sneezing, touching contaminated surfaces, or close contact with an infected person.
Though both conditions are viral, flu symptoms are typically more severe than cold symptoms.
