How do you treat bacterial infections?
• To treat you can use antibiotics
• Antibiotic means the destruction of life
• This works by only attacking cells with a cell
wall. Cells in the human body do not have a cell
wall, so it only disintegrates the cell walls of
bacteria.

day

not living you cannot destroy it.

T cells so it can no longer reproduce the virus.

antibiotics which covers a wide range.
Prevention for viruses

them often throughout the day

• How vaccines work:
* Inject using a needle or spray into a person. The
liquid contains the live virus (weakened) these will
ask as teachers to the immune system so they can
build up antibodies for it, or the inactivated virus
which makes your body produce more antibodies.
