How do infectious diseases work?
How are infections spread?
Ministry Of Health
Examples of airborne spread diseases:
Contaminated food or water
Some diseases can also be spread through contaminated food or water. Find out more about common foodborne illnesses on the Ministry for Primary Industries website.
What is the history of water and how does it contaminate and give people diseases
the system of how water is filtered through?
Still contains micro dirt. So wehn it arrives at the treatment plant a chemical called COHGULA Makes dirt stick together to make bigger and easier to spot it then sinks to the bottom of the tanka dn sticks there.
Then it moves to sand particles wich removes all the other bigger pice of debri
4 main stages
Untreated water past streams and dams etc The streams are
to stop debri.
They add chlorine to the water to kill of any bacteria that is in the water
Add lime to stable ph level
Fluride is added for dental purposes
How does water give people diseases?
Water related diseases cause 3.4 million deaths each year.
Contaminated water can cause many types of diarrheal diseases, including Cholera, and other serious illnesses such as Guinea worm disease, Typhoid, and Dysentery.
What is the source of water contamination..
There are groundwater chemicals that although are natural can still be harmful
Groundwater can be contaminated by sewage, fertiliser or fuel leaching through the soil although of the long process fo water treatment the little pieces of debri can stay with the flow of the water and camoflauge itself
What types of diseases do you get from contaminated water
diarrheal diseases, including Cholera
Guinea worm diseas
Germs can enter the body by:
directly from person to person
indirectly from an infected person to the environment (for example toys, door handles, bench tops, bedding and toilets) and then to another person who comes in contact with the contaminated environmental source.
What is the difference between bacteria and virus
What is the meaning of bacteria?
According to the dictonary
a member of a large group of unicellular things which have cell walls but lack organelles (any of a number of organized or specialized structures within a living cell) and an organized nucleus, including some which can cause disease.
breaking it down
What are bacteria?
Bacteria are tiny little organisms that are everywhere around us. We can't see them without a microscope because they are so small, but they are in the air, on our skin, in our bodies, in the ground, and all throughout nature.
Bacteria are single-celled microorganisms. Their cell structure is unique in that they don't have a nucleus (the central and most important part of an object, movement, or group, forming the basis for its activity and growth) and most bacteria have cell walls similar to plant cells.
They come in all sorts of shapes including rods, spirals, and spheres. Some bacteria can
"swim" around using long tails called flagella. Others just hang out or glide along.
Are bacteria dangerous?
Most bacteria aren't dangerous, but some are and can make us sick. These bacteria are called pathogens. Pathogens can cause diseases in animals and plants. Some examples of
pathogens are leprosy, food poisoning, pneumonia, tetanus, and typhoid fever.
Fortunately, we have antibiotics we can take which help to fight off the bad pathogens.
We also have antiseptics to help us keep wounds clean of bacteria and antibiotic soap
we use to wash to help keep off bad pathogens. Remember to wash your hands!
Are bacteria all bad?
Not at all. Actually most bacteria are very helpful to us.
They play an important role in the planet's ecosystem as well as in human survival.
What are the similarities
Both Bacteria and virus are single cell organisms of microscopic size. Both are able to exist by themselves. However there are some significant differences also between them.
They both spread by physical contact e.g: shaking hands They are also spread if you cough or sneeze as they go into the air
What is the meaning of virus.
Viruses are tiny particles that cause disease in people, other animals, and plants.
Different viruses cause the common cold, influenza (flu), chicken pox, measles, AIDS, and many other diseases.
Viruses are so tiny that people can see them only with powerful microscopes. Some viruses have a spherical, or round, shape.
Others are shaped like rods. Viruses are made up mostly of a substance called nucleic acid surrounded by protein.
According to the dictonary?
an infection or disease caused by a virus
What are the diffrences?
Additionally, bacteria contain ribosomes and viruses do not. Bacteria are also typically 1,000 nanometers long, whereas viruses are generally only 20–250 nanometers long.
antibiotics will get rid of bacteria infects but antibiotics will not get rid of viral infections
The major difference between them is that bacteria is able to produce itself .
