El resfriado común

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