The Causes of Infection An understanding of commonly encountered mi cro-organisms is essential for good infection control practice. Micro-organism s that cause disease are referred to as pathogenic organisms. They ma y be classified as follows: Bacteria are minute organisms about one-thousandth to five-thous andth of a millimetre in diameter. They are susceptible to a greater or lesser ext ent to

Contact precautions are used when a disease is known to be transmittable via direct or indirect contact. During this type of precaution‚ gowns and gloves must be worn while caring for the patient. Also if an image receptor is being used‚ it must be covered before coming in contact with the patient. Droplet precautions are used when a disease is known to be transmittable via close respiratory secretions. During this type of precaution‚ masks

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 Description Source: Centers for Disease Control and Prevention. Principles

perfected for an exponential amount of time. Even though vaccinations have been around for a while‚ many people are still unsure about them. With this in mind‚ there are many questions about how vaccines work‚ what they are‚ and how they help eradicate diseases. Vaccines work by introducing a weakened version of the virus or bacteria into the body. In fact‚ Vaccines are introduced into the body via injection. When a child is injected with the virus‚ it is a live‚ weakened version of the virus. If the

Most of them are completely harmless and some of them are very useful. But some bacteria can cause diseases‚ either because they end up in the wrong place in the body or simply because they are ’designed’ to invade us. Viruses - Viruses are too small to be seen by the naked eye. They can’t multiply on their own‚ so they have to invade a ’host’ cell
