1976 Philadelphia Legionnaires' Disease Outbreak
The 1976 Legionnaires disease outbreak, occurring in the late summer in Philadelphia, Pennsylvania, United States was the first occasion in which a cluster of a particular type of pneumonia cases were determined to be caused by the ''Legionella pneumophila'' bacteria. Previous outbreaks were retroactively diagnosed as being most probably caused by Legionella bacteria. Background On July 21, 1976, the American Legion opened its annual three-day convention at the Bellevue-Stratford Hotel in Philadelphia, Pennsylvania. More than 2,000 Legionnaires, mostly men, attended the convention. The date and city were chosen to coincide with America's celebration of the 200th anniversary of the signing of the US Declaration of Independence at Philadelphia in 1776. On July 27, three days after the convention ended, Legionnaire Ray Brennan, a 61-year-old retired US Air Force captain and an American Legion bookkeeper, died at his home of an apparent heart attack. Brennan had returned home from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Legionella
''Legionella'' is a genus of pathogenic gram-negative bacteria that includes the species '' L. pneumophila'', causing legionellosis (all illnesses caused by ''Legionella'') including a pneumonia-type illness called Legionnaires' disease and a mild flu-like illness called Pontiac fever. ''Legionella'' may be visualized with a silver stain or cultured in cysteine-containing media such as buffered charcoal yeast extract agar. It is common in many environments, including soil and aquatic systems, with at least 50 species and 70 serogroups identified. These bacteria, however, are not transmissible from person to person; furthermore, most people exposed to the bacteria do not become ill. Most outbreaks are traced to poorly maintained cooling towers. The side chains of the cell wall carry the bases responsible for the somatic antigen specificity of these organisms. The chemical composition of these side chains both with respect to components and arrangement of the different sugars de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1999 Bovenkarspel Legionellosis Outbreak
The Bovenkarspel legionellosis outbreak ( nl, Legionellaramp; Legionella disaster) began on 25 February 1999 in Bovenkarspel, the Netherlands, and was one of the largest outbreaks of legionellosis in history. With at least 32 dead and 206 severe infections, it was the deadliest legionellosis outbreak since the original 1976 outbreak in Philadelphia, United States. Between 19 and 28 February 1999, the Westfriese Flora took place in Bovenkarspel, one of the largest indoor flower exhibitions in the world (later the Holland Flowers Festival). A vendor had several recreational hot tubs on display, with one of them filled from a long-inactive firehose and heated to 37 degrees Celsius (98.6 degrees Fahrenheit). In the water that had previously stagnated inside the hose, a very aggressive type of '' legionella pneumophila'' bacterium had developed. The vendor did not add chlorine to the tubs, since customers were not permitted in them. From 7 March, 13 patients were admitted to the Wes ...

Independent Order Of Odd Fellows
The Independent Order of Odd Fellows (IOOF) is a non-political and non-sectarian international fraternal order of Odd Fellowship. It was founded in 1819 by Thomas Wildey in Baltimore, Maryland, United States. Evolving from the Order of Odd Fellows founded in England during the 18th century, the IOOF was originally chartered by the Independent Order of Oddfellows Manchester Unity in England but has operated as an independent organization since 1842, although it maintains an inter-fraternal relationship with the English Order. The order is also known as the ''Triple Link Fraternity'', referring to the order's "Triple Links" symbol, alluding to its motto "Friendship, Love and Truth". While several unofficial Odd Fellows Lodges had existed in New York City circa 1806–1818, because of its charter relationship, the American ...

Pontiac Fever
Pontiac fever is an acute, nonfatal respiratory disease caused by various species of Gram-negative bacteria in the genus ''Legionella''. It causes a mild upper respiratory infection that resembles acute influenza. Pontiac fever resolves spontaneously and often goes undiagnosed. Both Pontiac fever and the more severe Legionnaire's disease may be caused by the same bacteria, but Pontiac fever does not include pneumonia. Cause Species of ''Legionella'' known to cause Pontiac fever include ''Legionella pneumophila'', '' Legionella longbeachae'', ''Legionella feeleii'', ''Legionella micdadei'', and '' Legionella anisa''. Sources of the causative agents are aquatic systems and potting soil. The first outbreak caused by inhalation of aerosolized potting soil was discovered in New Zealand in January 2007. A total of 10 workers at a nursery came down with Pontiac fever. It was the first identification of ''L. longbeachae''. Pontiac fever does not spread from person to person. It is acquired ...

Swine Flu
Swine influenza is an infection caused by any of several types of swine influenza viruses. Swine influenza virus (SIV) or swine-origin influenza virus (S-OIV) refers to any strain of the influenza family of viruses that is endemic in pigs. As of 2009, identified SIV strains include influenza C and the subtypes of influenza A known as H1N1, H1N2, H2N1, H3N1, H3N2, and H2N3. Swine influenza virus is common throughout pig populations worldwide. Transmission of the virus from pigs to humans is rare, and does not always lead to human flu, often resulting only in the production of antibodies in the blood. If transmission causes human flu, it is called zoonotic swine flu. People with regular exposure to pigs are at increased risk of swine flu infections. Around the mid-20th century, identification of influenza subtypes was made possible, allowing accurate diagnosis of transmission to humans. Since then, only 50 such transmissions have been confirmed. These strains of swine flu rarel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HVAC
Heating, ventilation, and air conditioning (HVAC) is the use of various technologies to control the temperature, humidity, and purity of the air in an enclosed space. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. "Refrigeration" is sometimes added to the field's abbreviation as HVAC&R or HVACR, or "ventilation" is dropped, as in HACR (as in the designation of HACR-rated circuit breakers). HVAC is an important part of residential structures such as single family homes, apartment buildings, hotels, and senior living facilities; medium to large industrial and office buildings such as skyscrapers and hospitals; vehicles such as cars, trains, airplanes, ships and submarines; and in marine environments, where safe and Sick building syndrome, healthy building conditions are regulated with respect to temperature and ...
