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. Gay bathhouses, particularly in 1980s A gay bathhouse is a place where men who have sex with men meet for sex. In the 1980s at the advent of HIV/AIDS many men who used bathhouse ...

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. In present medical consensus, a focal infection is a localized infection, often asymptomatic, that causes disease elsewhere in the host, but focal infections are fairly infrequent and 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 Focal infection theory, rather, so explained virtually all diseases, including arthritis, atherosclero ...

Prevention Of HIV/AIDS
HIV prevention refers to practices that aim to prevent the spread of the human immunodeficiency virus (HIV). HIV prevention practices may be undertaken by individuals to protect 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 * Antiretroviral medicines or antiretroviral therapy (ART) * Pre-exposure prophylaxis * Postexposure prophylaxis * 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. In high income countries, Prevention of Mother to Child Transmission Programs (PMTC) including HIV testing of pregna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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, or other harmful and 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 ur ...

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, and nausea, 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 ...

Daycare
Child care, otherwise known as day care, is the care and supervision of a child or multiple children at a time, whose ages range from two weeks of age to 18 years. Although most parents spend a significant amount of time caring for their child(ren), child care typically refers to the care provided by caregivers that are not the child's parents. Child care is a broad topic that covers a wide spectrum of professionals, institutions, contexts, activities, and social and cultural conventions. Early child care is an equally important and often overlooked component of child's developments. Care can be provided to children by a variety of individuals and groups. Care facilitated by similar-aged children covers a variety of developmental and psychological effects in both caregivers and charge. This is due to their mental development being in a particular case of not being able to progress as it should be at their age. This care giving role may also be taken on by the child's extended f ...

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 "chil ...

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 prot ...

HIV/AIDS
Human immunodeficiency virus infection and acquired immunodeficiency syndrome (HIV/AIDS) is a spectrum of conditions caused by infection with the human immunodeficiency virus (HIV), a retrovirus. Following initial infection an individual may not notice any symptoms, or may experience a brief period of influenza-like illness. Typically, this is followed by a prolonged incubation period with no symptoms. If the infection progresses, it interferes more with the immune system, increasing the risk of developing common infections such as tuberculosis, as well as other opportunistic infections, and tumors which are rare in people who have normal immune function. These late symptoms of infection are referred to as acquired immunodeficiency syndrome (AIDS). This stage is often also associated with unintended weight loss. HIV is spread primarily by unprotected sex (including anal and vaginal sex), contaminated blood transfusions, hypodermic needles, and from mother to ch ...
