Patient Under Investigation
A patient under investigation (or a person under investigation) refers to a person who had been in close contact with a person with confirmed infection or/and may have been to place where there is an outbreak or superspreading event. This person exhibits the symptoms of the disease and is required to be tested, and undergo a quarantine or isolation while waiting for the laboratory results. It is a term used by health care workers in classifying patients during evaluation and testing in contact tracing in times of infectious disease outbreaks In epidemiology, an outbreak is a sudden increase in occurrences of a disease when cases are in excess of normal expectancy for the location or season. It may affect a small and localized group or impact upon thousands of people across an entire ....

Disease Outbreak
In epidemiology, an outbreak is a sudden increase in occurrences of a disease when cases are in excess of normal expectancy for the location or season. It may affect a small and localized group or impact upon thousands of people across an entire continent. The number of cases varies according to the disease-causing agent, and the size and type of previous and existing exposure to the agent. Outbreaks include many epidemics, which term is normally only for infectious diseases, as well as diseases with an environmental origin, such as a water or Foodborne illness, foodborne disease. They may affect a region in a country or a group of countries. Pandemics are near-global disease outbreaks when multiple and various countries around the Earth are soon infected. Definition The terms "outbreak" and "epidemic" have often been used interchangeably. Researchers Manfred S. Green and colleagues propose that the latter term be restricted to larger events, pointing out that ''Chambers Diction ...

Superspreading Event
A superspreading event (SSEV) is an event in which an infectious disease is spread much more than usual, while an unusually contagious organism infected with a disease is known as a superspreader. In the context of a human-borne illness, a superspreader is an individual who is more likely to infect others, compared with a typical infected person. Such superspreaders are of particular concern in epidemiology. Some cases of superspreading conform to the 80/20 rule, where approximately 20% of infected individuals are responsible for 80% of transmissions, although superspreading can still be said to occur when superspreaders account for a higher or lower percentage of transmissions. In epidemics with such superspreader events, the majority of individuals infect relatively few secondary contacts. The degree to which superspreading contributes to an epidemic is often quantified by the ''t20'' metric, which denotes the proportion of infections attributable to the most infectious 20% ...

Quarantine
A quarantine is a restriction on the movement of people, animals, and goods which is intended to prevent the spread of disease or pests. It is often used in connection to disease and illness, preventing the movement of those who may have been exposed to a communicable disease, yet do not have a confirmed medical diagnosis. It is distinct from medical isolation, in which those confirmed to be infected with a communicable disease are isolated from the healthy population. The concept of quarantine has been known since biblical times, and is known to have been practised through history in various places. Notable quarantines in modern history include the village of Eyam in 1665 during the bubonic plague outbreak in England; East Samoa during the 1918 flu pandemic; the Diphtheria outbreak during the 1925 serum run to Nome, the 1972 Yugoslav smallpox outbreak, the SARS pandemic, the Ebola pandemic and extensive quarantines applied throughout the world during the COVID-19 pande ...

Isolation (health Care)
In health care facilities, isolation represents one of several measures that can be taken to implement in infection control: the prevention of communicable diseases from being transmitted from a patient to other patients, health care workers, and visitors, or from outsiders to a particular patient (reverse isolation). Various forms of isolation exist, in some of which contact procedures are modified, and others in which the patient is kept away from all other people. In a system devised, and periodically revised, by the U.S. Centers for Disease Control and Prevention (CDC), various levels of patient isolation comprise application of one or more formally described "precaution". Isolation is most commonly used when a patient is known to have a contagious (Transmission (medicine), transmissible from person-to-person) viral illness, viral or Bacteria, bacterial illness. Special equipment is used in the management of patients in the various forms of isolation. These most commonly in ...

CNN Philippines
CNN Philippines (abbreviated sometimes as CNN PH) was a Philippine free-to-air television network owned and operated by Nine Media Corporation, together with Radio Philippines Network (RPN), under a license from Warner Bros. Discovery Asia-Pacific. CNN Philippines was the fifth local franchise of CNN in Asia after CNN Indonesia, CNN Türk, CNN Arabic, and CNN-IBN (now CNN-News18 in India). It was formed after a brand licensing agreement with CNN Worldwide and Nine Media in 2014. It then launched on March 16, 2015, replacing 9TV, and was available on various platforms, including cable, satellite, live-streaming, and RPN's television stations. CNN Philippines' local programming was produced from the Worldwide Corporate Center in Mandaluyong. It maintained its analog transmitter located at the RPN Compound in Diliman, Quezon City, while digital transmission facilities were located at the Crestview Subdivision in Antipolo, Rizal. Citing financial losses, CNN Philippines ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Contact Tracing
In public health, contact tracing is the process of identifying people who may have been exposed to an infected person ("contacts") and subsequent collection of further data to assess transmission. By tracing the contacts of infected individuals, testing them for infection, and isolating or treating the infected, this public health tool aims to reduce infections in the population. In addition to infection control, contact tracing serves as a means to identify high-risk and medically vulnerable populations who might be exposed to infection and facilitate appropriate medical care. In doing so, public health officials utilize contact tracing to conduct disease surveillance and prevent outbreaks. In cases of diseases of uncertain infectious potential, contact tracing is also sometimes performed to learn about disease characteristics, including infectiousness. Contact tracing is not always the most efficient method of addressing infectious disease. In areas of high disease prevale ...

Communicable Diseases
infection is the invasion of tissues by pathogens, their multiplication, and the reaction of host tissues to the infectious agent and the toxins they produce. An infectious disease, also known as a transmissible disease or communicable disease, is an illness resulting from an infection. Infections can be caused by a wide range of pathogens, most prominently bacteria and viruses. Hosts can fight infections using their immune systems. Mammalian hosts react to infections with an innate response, often involving inflammation, followed by an adaptive response. Treatment for infections depends on the type of pathogen involved. Common medications include: * Antibiotics for bacterial infections. * Antivirals for viral infections. * Antifungals for fungal infections. * Antiprotozoals for protozoan infections. * Antihelminthics for infections caused by parasitic worms. Infectious diseases remain a significant global health concern, causing approximately 9.2 million deaths in 20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
