Introduction

P2- Describe how named examples of a viral, a bacterial and a fungal infection may be spread Bacteria are single celled micro-organisms that are found almost everywhere. Tetanus is an example of a bacterial infection, caused by the bacterium Clostridium tetani. This bacterium is found in soil, animal waste and manure, but they can also live in street dust and inside small cracks in buildings. Their main mode of transmission is via the spores that they let off, eventually producing pathogenic microbes that grow when the conditions are right. The disease can arise from a minor injury, such as a small cut from a rusty nail, but as time goes on it turn out to be quite serious, as the pathogens get into the cut and start to multiply. The toxin produced by the bacteria is highly poisonous and affects the nervous system, causing muscle spasm. ...read more.

I am now going to be talking about Hepatitis B, which is a very serious viral disease. <-- Here is an example of what the Hepatitis B virus looks like. (www.philadelphia-reflections.com) Hepatitis B virus (HBV) is a very serious disease which can result in liver failure and death. Its main mode of transmission is through the blood and bodily fluids of an infected person. Common symptoms of this disease include; flu-like symptoms, such as tiredness, headaches, fever and general aches and pains, loss of appetite, nausea or vomiting, diarrhoea and abdominal pains. Jaundice is another sign which occurs and causes your skin (and sometimes the whites of eyes) to become yellow. (P.Ayling, 2007). <-- Here is a diagram which shows the area of the body that Hepatitis B affects. (www.bangkokhospital.com) The best thing to do if worried about catching HBV is contact a doctor or GP and they may encourage the person to take a number of injections of hepatitis B vaccine for a period of4-6 months. ...read more.

Conclusion

These fungi are parasitic, which means they feed off other organisms to stay alive. Your feet provide a warm, dark and humid environment, which are the ideal conditions needed for dermatophytes to grow, causing the skin to be red, flaky and itchy. (www.nhs.uk) The infection is normally mild and is easy to treat. If properly treated, an athlete's foot infection will normally only last for a few weeks, however, if left untreated, this skin condition can last for several months or even years. Although not all cases of athlete's foot can be prevented, there are some things which you can to do to help prevent it and this includes; practicing good foot hygiene, avoid using tight-footing shoes and changing socks, stockings and tights on a regular basis. The best way to treat the disease is by using a whole range of antifungal treatment which will help to kill the fungi that is causing the infection, these come in the form of creams, sprays, liquids and powders.
