Kinds of diseases:
-communicable (contagious - ie, you can "catch it")
-non-communicable (not contagious - ie, you can`t "catch it")
-Social
-Microbial
-Viral
-Environmental
-Genetic
-Life style
-Mental
-Degenerative (due to degeneration: the gradual deterioration of specific tissues, cells, or organs with corresponding impairment or loss of function, caused by injury, disease, or aging)Due to a deficiency or nutritional disorder.

Examples of these diseases:
SARS- Contagious
Down Syndrome- Genetic
Binge Eating- Mental
Cancer and heart disease- Life Style
Alzheimer's- Degenerative
Obesity- non-communicable
STD's- social
Small Pox- Viral

Conjunctivitis-Microbial

Minamata Disease:
A disorder caused by methyl mercury poisoning that was first described in the inhabitants of Minamata Bay, Japan and resulted from their eating fish contaminated with mercury industrial waste. The disease is characterized by peripheral sensory loss, tremors, dysarthria,ataxia, and both hearing and visual loss. Even an unborn child can be affected by this disease, when methyl mercury readily crosses the placenta from mother to fetus and is damaging, particularly to the developing brain. Children born with Minamata disease can have growth deficiency, microcephaly (an abnormally small head), severe mental retardation and be deaf and blind.

What kind of disease is Minamata?:
Minamata disease is a result of eating fish contaminated with mercury industrial waste, therefore it has infected the whole environment of Minamata bay, Japan so I think its an environmental disease.

VIRUS-
Can only be seen with an electron microscope because, it is so small. They hitch a ride on something: other organisms wind or water to spread from one living thing to another. They are not considered to be living because; they don’t self-reproduce, grow, feed or produce waste. Viruses are made of DNA coated in protein. Once the virus has invaded the body it can get to a point where the cell breaks open and releases the virus particles which then invade other cells. Viruses are hard to get medication for and cannot be stopped by antibiotics. E.g. warts.
BACTERIA-
All bacteria is made up of one cell, but they can join together to form pairs, chains or clusters.Bacteria can multiply very quickly under the right conditions.Bacteria can remain inactive for days or even years without the victim knowing.Many types of bacteria can be killed using penicillin or other types of antibiotics. An example is Tetanus which can be treated with sedatives and muscle relaxants if you have symptoms.
FUNGI-
Many fungi are parasites that feed on living plants and animals to survive. This often results in a disease. Fungi commonly invade hair, nails and your skin. They are not usually associated with infection, but will infect a person with the intention to weaken their immune system. Example is ringworm, which actual is not associated with any worms.
WORMS-
Worms are a type of parasite and their survival is based on using their hosts for food. An example of a parasitic worm is a tapeworm. There are a few types; two are the pork tapeworm and the cow tapeworm. They can measure up to 10 metres in length.
PROTOZOA-
Protozoa (protisis) can cause disease especially in tropical/subtropical areas.
Although most are harmless to humans, some parasitic times can cause serious illness.
By forming a cyst around themselves they are very hardy and can contaminate water supplies,
Malaria is caused by a parasitic protozoan that lives in red blood cells and liver cells
Amoebic dysentery is another example of these single celled beings.
African sleeping sickness.
