Winter Woes: Unmasking the Spread of Seasonal Illnesses

The video explores why winter illnesses are prevalent, focusing on viruses and their transmission. It includes a visit to the Pasteur Institute, explaining how viruses differ from bacteria and why they thrive in cold weather. Experiments demonstrate airborne and manual transmission, emphasizing the importance of hygiene to prevent infections.
