This video was released by the Disney company in 1943. Still relevant today.
In this propaganda short, the viewers are taught about how the mosquito can spread malaria. A young mosquito flies into a house and consumes the blood of an infected human. She then consumes the blood of a healthy human, transmitting the disease into him. It turns out that this is actually a film within a film and the Seven Dwarves are watching it. They volunteer to get rid of the mosquito by destroying her breeding grounds.
You can find this in Spanish and we have also dubbed it into Burmese.
