The video discusses pathogens, microorganisms that cause diseases, and their transmission methods: through air, contaminated food or water, and direct contact. It highlights examples like influenza, cholera, and athlete's foot. The video emphasizes prevention methods such as hygiene, killing vectors, vaccination, and quarantine. It concludes with a recap and a preview of future videos focusing on these topics.

What are pathogens?

• Microorganisms that cause disease

• Large organisms that are harmless

• Non-living entities that spread through air

• Chemical substances used in vaccines

• By consuming contaminated food

What is a common method to prevent the spread of pathogens?

• Ignoring hygiene practices

• Using insecticides
