A bacteria is a living things that are neither plants nor animals‚ but belong to a group all by themselves. They are very small--individually not more than one single cell--however there are normally millions of them together‚ for they can multiply really fast.

Chain of Infection As described above‚ the traditional epidemiologic triad model holds that infectious diseases result from the interaction of agent‚ host‚ and environment. More specifically‚ transmission occurs when the agent leaves its reservoir or host through a portal of exit‚ is conveyed by some mode of transmission‚ and enters through an appropriate portal of entry to infect a susceptible host. This sequence is sometimes called the chain of infection. Figure 1.19 Chain of Infection Image

A virus is a simple structure. It is not a cell nor is it living. A virus is simply a coat of protein wrapped around genetic material.

certain diseases. The environment plays an important role as well. Children in day care centers and in school pass infections around and then take them home and pass them to siblings and parents. This is a cycle that is difficult to break. Children also don’t always practice good hygiene and that makes them both susceptible to as well as good transmitters of disease. Many human infections are caused by either bacteria or viruses. Immunisation is available to prevent many important bacterial diseases

Hand washing is widely acknowledged to be the single most important activity for reducing the spread of infection‚ yet evidence suggests that many healthcare professionals do not use the correct technique. This means that areas of the hands can be missed. The author feels that this is crucial in preventing and controlling infection and this is why the particular
