211. Mosquitoes.—Mosquitoes carry malaria and yellow fever from sick persons to the well. If there were no mosquitoes, there would be no malaria or yellow fever.
Mosquitoes are hatched in water, and the young are called wigglers. We may often see them in rain barrels. We may get rid of mosquitoes by emptying all rain barrels and pails and cans of dirty water, at least once a week, and by drying up swamps and marshes.
WHAT WE HAVE LEARNED
1. We catch a fever by taking disease germs into the body.
2. Disease germs cannot be seen without a strong microscope.
3. The germs may be found in dust and dirt.
4. Slops from our houses are often full of the germs.
5. You may take germs into your body by putting pencils and other things into your mouth, and by drinking from a public drinking cup.
6. Spitting on the floor or pavement may scatter disease germs.
