The causes of infection. Diseases can be classified as genetic‚ metabolic‚ or infectious. Infectious diseases are caused by bacteria‚ viruses‚ fungi and parasites that use our body as a host for reproduction and cause illness. Bacteria‚ viruses‚ fungi and parasites. These are all microorganisms which cause infection‚ yet they are all different in structure‚ required environment and conditions needed to thrive and multiply. Bacteria is a single celled organism. It’s shape and size can vary

The most common infection in the health care setting is Clostridium difficile (C. difficile) and it is associated with sky rocketing hospital costs‚ deaths and complications. (Zacharioudakis‚ et al.‚ 2015) According to studies released in the United States by the Centers for Disease Control and Prevention (CDC) in 2015‚ the current economic burden of infectious C. difficile has become the most common microbial cause of recurrent antibiotic-associated diarrhea and other gastrointestinal illnesses

droplets dispersed by sneezing or coughing. Skin infections are common‚ but the bacteria can spread through the bloodstream and infect distant organs. Skin infections may cause blisters‚ abscesses‚ and redness and swelling in the infected area. The diagnosis is based on the appearance of the skin or identification of the bacteria in a sample of the infected material. Thoroughly washing the hands can help prevent spread of infection. Antibiotics are chosen based on whether they

Many of the bacteria that cause common bacterial infection are mutating and therefore gaining resistance. This means that the original antibiotics that were once used to treat these common illnesses are becoming increasing ineffective. This resistance delays treatment as the original antibiotics are ineffective. This can lead to the disease worsening and even death. This means that common illnesses that were once easily treated by antibiotics are no longer so easy to treat. This results in increased

Cross Infection Definition Cross infection is the physical movement or transfer of harmful bacteria from one person‚ object‚ or place to another‚ or from one part of the body to another (such as touching a staph-infected hand to the eye). When this cross infection occurs in a hospital or long-term care facility it is called a nosocomial infection. Community acquired infections are those contracted anywhere except a hospital or long-term care facility. Description Cross infection accounts for

IC02 Causes and spread of infection The difference between bacteria‚ viruses‚ fungi and parasites are: Viruses are coated genetic material that invade cells and use the cell’s apparatus for reproduction. Bacteria are single celled organisms. Some classify them as a separate (fourth) kingdom on the tree of life. Fungi are multi-celled organisms that form a third Kingdom of life‚ along with the plant kingdom and the animal kingdom. Parasites are plants or animals that derive benefit
