Cause and Spread of Infection
Cause and spread of infection
1.1. Identify the differences between bacteria, viruses, fungi and parasites
All 4 are different types of pathogens
Bacteria is a single celled organism that multiply by themselves. They lives within and on most living and nonliving things. The majority of bacteria’s are harmless and beneficial to the human body but some can cause infectious diseases. A bacterium usually affects one part of the body and doesn’t spread across or through the body. Bacterial infections are normally treated with a cause of antibiotics.
Viruses: are made up of genes and proteins that spread throughout the body by invading the body’s own cells so they can reproduce and multiply in the body. They use the body’s cells as a host because they are unable to multiply on their own. They are normally spread directly from human to human. Viruses can be very tough and there are not many effective medicines available for viral diseases.
There are currently 21 families of viruses known to cause disease in humans.
Fungi: like to grow in warm, moist places. Some fungi can be beneficial to us such as penicillin, but certain types of fungi can be harmful to our health. Like bacteria and viruses, some fungi can act as pathogens. Human fungal diseases can occur due to infection or fungal toxins. Symptoms for fungal diseases can be as common as itching, coughing, fever, wheezing, but they can also be as serious as meningitis or even death
Parasites are organisms that use other organism for its survival. They draw nourishment and other needs from its host organism. Parasites that cause infection and disease are known as Pathogenic parasites
1.2. Identify common illnesses and infections caused by bacteria, viruses, fungi and parasites
Bacteria: Ecoli/food poisoning, MRSA, CDIF, Sickness and diarrhea
Viruses: Common cold, Influenza, Chicken pox, Cold sores, HIV
Fungi: Athletes foot, Thrush, yeast infections, Ring Worm
Parasites: Tape worms, Scabies, Malaria
