Focus Of Infection
A focus of infection is a place containing whatever epidemiological factors are needed for transmission of an infection. Any focus of infection will have a source of infection, and other common traits of such a place include a human community, a vector population, and environmental characteristics adequate for spreading infection. Examples of focus of infection Water pump in 1854 London In 1854 London physician John Snow discovered that people who drank from a particular water pump contracted cholera, and proposed that drinking this water from this pump was the cause of the illness. At the time people did not readily believe germ theory of disease, instead favoring miasma theory. The discovery of the water pump as a source of infection set a precedent which helped establish epidemiology as a science.

Focal Infection Theory
Focal infection theory is the historical concept that many chronic diseases, including systemic disease, systemic and common ones, are caused by focal infections. A focal infection is a localized infection, often asymptomatic, that causes disease elsewhere in the host, but the present medical consensus is that focal infections are fairly infrequent and mostly limited to fairly uncommon diseases. (Distant injury is focal infection's key principle, whereas in ordinary infectious disease, the infection itself is systemic, as in measles, or the initially infected site is readily identifiable and invasion progresses contiguously, as in gangrene.)J Craig Baumgartner, José F Siqueira Jr, Christine M Sedgley & Anil Kishen, ch 7 "Microbiology of endodontic disease", in John I Ingle, Leif K Bakland & J Craig Baumgartner, eds, ''Ingle's Endodontics'', 6th edn (Hamilton Ontario: BC Decker, 2008)p 221–24 Historical focal infection theory, rather, so explained virtually all diseases, includi ...

Prevention Of HIV/AIDS
HIV prevention refers to practices that aim to prevent the spread of the HIV/AIDS, human immunodeficiency virus (HIV). HIV prevention practices may be undertaken by individuals to protect Self care, their own health and the health of those in their community, or may be instituted by governments and community-based organizations as public health policies. Prevention strategies Interventions for the prevention of HIV include the use of: * Barrier methods, such as the use of condoms or dental dams during sexual activity * Management of HIV/AIDS, Antiretroviral medicines or antiretroviral therapy (ART) * Pre-exposure prophylaxis for HIV prevention, Pre-exposure prophylaxis * Post-exposure prophylaxis * Male Circumcision, Voluntary male circumcision (see also Circumcision and HIV) * Microbicides for sexually transmitted diseases * Low dead space syringes The consistent, correct use of condoms is one proven method for preventing the spread of HIV during sexual intercourse.

Hand Washing
Hand washing (or handwashing), also known as hand hygiene, is the act of cleaning one's hands with soap, soap or handwash and water to remove viruses, bacteria, microorganisms, dirt, grease, and other harmful or unwanted substances stuck to the hands. Drying of the washed hands is part of the process as wet and moist hands are more easily recontaminated. If soap and water are unavailable, hand sanitizer that is at least 60% (v/v) Alcohol (chemistry), alcohol in water can be used as long as hands are not visibly excessively dirty or greasy. Hand hygiene is central to preventing the spread of Infection, infectious diseases in home and everyday life settings. The World Health Organization (WHO) recommends washing hands for at least 20 seconds before and after certain activities. These include the five critical times during the day where washing hands with soap is important to reduce Fecal–oral route, fecal-oral transmission of disease: after using the Toilet (room), toilet (for ...

Influenza-like Illness
Influenza-like illness (ILI), also known as flu-like syndrome or flu-like symptoms, is a medical diagnosis of possible influenza or other illness causing a set of common symptoms. These include fever, shivering, chills, malaise, dry cough, loss of appetite, body aches, nausea, and sneezing typically in connection with a sudden onset of illness. In most cases, the symptoms are caused by cytokines released by immune system activation, and are thus relatively non-specific. Common causes of ILI include the common cold and influenza, which tends to be less common but more severe than the common cold. Less common causes include side effects of many drugs and manifestations of many other diseases. Definition The term ILI can be used casually, but when used in the surveillance of influenza cases, can have a strict definition. The World Health Organization defines an illness as an ILI if the patient has a fever greater than or equal to 38 °C and a cough, which began in the last 10 days ...

Daycare
Child care, also known as day care, is the care and supervision of one or more children, typically ranging from three months to 18 years old. Although most parents spend a significant amount of time caring for their child(ren), childcare typically refers to the care provided by caregivers who are not the child's parents. Childcare is a broad topic that covers a wide spectrum of professionals, institutions, contexts, activities, and social and cultural conventions. Early childcare is an important and often overlooked component of child development. A variety of people and organizations are able to care for children. The child's extended family may also take on this caregiving role. Another form of childcare is that of center-based childcare. In lieu of familial caregiving, these responsibilities may be given to paid caretakers, orphanages or foster homes to provide care, housing, and schooling. Professional caregivers work within the context of center-based care (including c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Childcare Infection
Infection in childcare is the spread of infection during childcare, typically because of contact among children in daycare or school. This happens when groups of children meet in a childcare environment, and there any individual with an infectious disease may spread it to the entire group. Commonly spread diseases include influenza-like illness and enteric illnesses, such as diarrhea among babies using diapers. It is uncertain how these diseases spread, but hand washing reduces some risk of transmission and increasing hygiene in other ways also reduces risk of infection. Due to social pressure, parents of sick children in childcare may be willing to give unnecessary medical care to their children when advised to do so by childcare workers and even if it is against the advice of health care providers. In particular, children in childcare are more likely to be given antibiotics than children outside of childcare. Mechanism of transmission The presumption behind the idea of a "child ...

Safe Sex
Safe sex is sexual activity using methods or contraceptive devices (such as condoms) to reduce the risk of transmitting or acquiring sexually transmitted infections (STIs), especially HIV. "Safe sex" is also sometimes referred to as safer sex or protected sex to indicate that some safe sex practices do not eliminate STI risks. It is also sometimes used colloquially to describe methods aimed at preventing pregnancy that may or may not also lower STI risks. The concept of "safe sex" emerged in the 1980s as a response to the global AIDS epidemic, and possibly more specifically to the AIDS crisis in the United States. Promoting safe sex is now one of the main aims of sex education and STI prevention, especially reducing new HIV infections. Safe sex is regarded as a harm reduction strategy aimed at reducing the risk of STI transmission. Although some safe sex practices (like condoms) can also be used as birth control (''contraception''), most forms of contraception do not ...

Without treatment, it can lead to a spectrum of conditions including acquired immunodeficiency syndrome (AIDS). It is a Preventive healthcare, preventable disease. It can be managed with treatment and become a manageable chronic health condition. While there is no cure or vaccine for HIV, Management of HIV/AIDS, antiretroviral treatment can slow the course of the disease, and if used before significant disease progression, can extend the life expectancy of someone living with HIV to a nearly standard level. An HIV-positive person on treatment can expect to live a normal life, and die with the virus, not of it. Effective #Treatment, treatment for HIV-positive people (people living with HIV) involves a life-long regimen of medicine to suppress the virus, making the viral load undetectable. Treatment is recommended as soon as the diagnosis is made. An HIV-positive person who has an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
