Causes Of Flu And The Common Cold

The flu is caused by influenza viruses that infect the nose, throat, and lungs. These viruses spread when people with the flu cough, sneeze, or talk, sending droplets with the virus into the air and potentially into the mouths or noses of people who are nearby. You can also get the flu by touching a surface or object that has the flu virus on it and then touching your mouth, eyes, or nose.

Allergy to changes in weather or an infection by a virus is considered an important causative factor of the common cold. As a result, the mucous membranes of the upper respiratory tract get inflamed. This leads to symptoms like sneezing, running nose, headache, sore throat, body pain, etc. Different viruses can cause a cold; among them, Rhinoviruses are the most cause of the common cold.
