1.– HEALTH AND ILLNESS. We can speak about two types of health: .– Physical health: when all organs in our body work in a right way, and we do not feel any pain. .– Mental health: when we feel good with ourselves and with the rest of people. When we don’t have any psychological disorder.
Remember something about health.
Health is a state of complete physical and mental well-being, not only the absence of disease or pain. 2
So we can speak about physical diseases and mental diseases. If we have a physical disease, our body does not work properly and we feel bad. We have fever, we have a cough, we sneeze, or we have a pain… These disorders are called symptoms and they help the doctor to know what type of disease we have.

When we have a mental disorder, we do not feel good with ourselves like in depression, stress, anorexia... Illness or disease is a state of being unhealthy in our body or mind. 2.– TYPES OF DISEASES. First, we are going to divide diseases in two great groups, depending on their origin: 2.1.– Infectious diseases: If an infectious agent gets into your body, you will be ill. These agents are microscopic, and the most common ones are pathogenic bacteria, and viruses. We can get the disease when we breath infected air (air with bacteria or viruses), or when we touch infected objects, when a mosquito or another animal bites us, by an open wound in our skin...

Viruses in the air.(Contagious disease)
Infectious diseases are transmitted by infectious agents (germs). Example: the flu. Non-infectious diseases are caused by other reasons. Example: a heartatack.
A.- Contagious diseases: when the disease is transmitted by contact from an infected person, or object.The transmission could be through the air (caughs, sneezes…), by touching the other person, by a mosquito (malaria)… B.– Non-contagious diseases: When the disease can’t be transmitted from an infected person to another one. USEFUL WORDS: .– healt .– illness / disease / sickness .– symptoms .– infectious / non-infectious
