HEALTH

Health is a

state of physical

Illness is the

opposite of

health.

Symptoms, like

coughs, pain or

fever, tell us that

our bodies are ill.

OTHER MICRO-ORGANISMS

A virus is not a

micro-

organism. It

causes

infectious

illnesses.

It is not a living

thing but it

needs cells to

carry out its life

processes.

VIRUSES

Pathogenic micro-

organisms can

enter our bodies in

different ways:

The respiratory

system.

The digestive

system.

Through cuts and

wounds in the skin.

PREVENTING AND TREATING INFECTIOUS ILLNEESSES.

Disinfect wounds

Wash your hands

before eating or

handling food

Wash uncooked

food

Cover your mouth

when you cough

or sneeze

Do not share

eating utensils

HOW CAN WE PREVENT INFECTIONS?

Vaccines

introduce into

our bodies the

micro-organisms

or virus that is

making us ill.

The body reacts

to the virus and

produces

substances to

destroy it.

VACCINES

Infections caused by

bacteria are treated

with antibiotics.

Infections caused by

fungi are treated

with anti-fungal

medicines.

Infections caused by

viruses are only

treated with

medicines that help

to reduce

symptoms.
