Our Foe–The Fly

Our Foe– The Fly

(Follow the arrow):
Female flies lay many eggs in a cesspool:
eggs become maggots;
maggots become pupa;
pupa turn into cocoons;
cocoons break and flies come out, flying everywhere and finding food

(Columns from left to right):

(Column one):
A child suffer from dysentery. The cloths with his excrement are laid on the ground. Flies gather on the cloths and pick up the bacterias of dysentery on their feet.
These bacteria get on a baby’s bottle. When he drinks milk, he swallows the bacterias
and is infected with dysentery.

(Column two):
A person suffers from cholera and experiences diarrhea in the restroom. Flies gather and their feet pick up the bacteria of cholera again.
These bacteria get on a person’s bowl. When he eats food, he swallows the bacteria
and is infected with cholera.

(Column three):
A person suffers typhoid fever, lying on an indoor bed. Flies gather and their feet are covered with the bacteria of typhoid.
The bacteria get on a muskmelon. When someone eats it, he swallows the bacterias
and be infected with typhoid.

(Column four):
A person suffers from rickets. Flies eat the phlegm he spits on the ground, picking up  the infecting bacteria of rickets on their feet.
These bacterias get on a piece of cookie. When a child eats it, he swallows the bacterias
and is infected with rickets.

(Bottom text in red):
Most diseases spread through the flies in summer: make a fly swatter, prepare fly traps, and place fly paper, then the flies will be diminished. Flies cannot enter items with iron coverage. Kill and prevent flies, then disease will not intrude.
