Malnourished
The conditions when the body does not get a balanced diet.
Antibiotic

Bacteria
Single-celled microorganisms that can reproduce very rapidly. Many bacteria are useful, for example, gut bacteria and decomposing bacteria, but some cause disease.
Culture medium
A substance contains the nutrients needed for microorganisms to grow.
Epidemic
When more cases of infectious disease are recorded than would normally be expected.
Immune system
The body system which recognises and destroys foreign cells or pretend such as invading pathogens.
Immunisation
Giving a vaccine that allows immunity to develop without exposure to the disease itself.
Infectious disease
