Treatment and Prevention
Viable treatment and prevention strategies disrupt the infection cycle. For example, direct transmission can be diminished by adequate hygiene, maintaining a sanitary environment, and health education.
When infection attacks the body, anti-infective drugs can suppress the infection. Four types of anti-infective or drugs exist: antibacterial (antibiotic), antiviral, antitubercular, and antifungal. Depending on the severity and the type of infection, the antibiotic may be given by mouth, injection or may be applied topically. Severe infections of the brain are usually treated with intravenous antibiotics. Sometimes, multiple antibiotics are used to decrease the risk of resistance and increase efficacy. Antibiotics only work for bacteria and do not affect viruses. Antibiotics work by slowing down the multiplication of bacteria or killing the bacteria. The most common classes of antibiotics used in medicine include penicillin, cephalosporins, aminoglycosides, macrolides, quinolones and tetracyclines.
Techniques like hand washing, wearing gowns, and wearing face masks can help prevent infections from being passed from the surgeon to the patient or vice versa. Frequent hand washing remains the most important defense against the spread of unwanted organisms. Nutrition must be improved and one has to make changes in life style- such as avoiding the use of illicit drugs, using a condom, and entering an exercise program. Cooking foods well and avoiding foods that have been left outside for a long time is also important. Do not take antibiotics for longer than needed. Long term use of antibiotics leads to resistance and chances of developing opportunistic infections like clostridium difficile colitis. Vaccination is another means of preventing infections by facilitating the development of immune resistance in vaccinated hosts.

Famous quotes containing the words treatment and, treatment and/or prevention:
“James’s great gift, of course, was his ability to tell a plot in shimmering detail with such delicacy of treatment and such fine aloofness—that is, reluctance to engage in any direct grappling with what, in the play or story, had actually “taken place”Mthat his listeners often did not, in the end, know what had, to put it in another way, “gone on.””
—James Thurber (1894–1961)
“I feel that any form of so called psychotherapy is strongly contraindicated for addicts.... The question “Why did you start using narcotics in the first place?” should never be asked. It is quite as irrelevant to treatment as it would be to ask a malarial patient why he went to a malarial area.”
—William Burroughs (b. 1914)
“... if this world were anything near what it should be there would be no more need of a Book Week than there would be a of a Society for the Prevention of Cruelty to Children.”
—Dorothy Parker (1893–1967)
