The common cold

The video explains the common cold, a frequent illness caused by viruses. It details how these viruses spread through coughing, sneezing, or touching infected surfaces. The body's immune system responds by producing mucus and deploying white blood cells to fight the virus, causing symptoms like fever and tiredness. While medicines can alleviate symptoms, there is no cure for the cold. Eventually, the immune system overcomes the virus, restoring health until the next infection.

Why is there no cure for the common cold despite scientific efforts?
