When you get sick from a germ or bug, it is called an infection.
Viruses can cause colds and the flu and make you feel terrible.
How many of you have had a cold before?
How did it make you feel?
Do you know what kind of bugs causes colds and the flu?
Sum up - Viruses cause colds and flu and make you feel miserable.Have you ever heard of antibiotics?
How many of you have had to take antibiotics before?
Sum up - Antibiotics are drugs that work against bacteria. Antibiotics don't work against viruses like colds and flu.Do you know what happens when someone takes antibiotics when they have a cold or the flu?
Do you think it helps them?
Sum up - People hope that antibiotics will help them get better faster, but antibiotics don't work at all against viruses like colds and the flu.Do you know what else happens when people take antibiotics for colds and the flu?
The big problem is that bacteria get used to the antibiotics and can become resistant to antibiotics when you take them for colds and the flu. The antibiotics don't help the cold, but they cause resistance.
I'll bet you don't know what resistance means.
Sum up - Antibiotic resistance means that antibiotics don't work any more. The bacteria become stronger and harder to kill.
Some people call these superbugs. This is very serious because you won't have antibiotics to treat you when you get an infection caused by bacteria like an ear infection.
So, today we learned:
Wash your hands. Washing your hands is the best way to prevent the spread of infections.
Viruses and bacteria are very different from each other.
Not all bugs need drugs. Viruses like colds and the flu don't get any better with antibiotics.
Using antibiotics for colds and the flu can cause antibiotic resistance.
