Transmission-based precautions are infection-control precautions in health care, in addition to the so-called "standard precautions". They are the latest routine infection prevention and control practices applied for patients who are known or suspected to be infected or colonized with infectious agents, including certain epidemiologically important pathogens, which require additional control ...
Post-exposure prophylaxis, also known as post-exposure prevention (PEP), is any preventive medical treatment started after exposure to a pathogen in order to prevent the infection from occurring. It should be contrasted with pre-exposure prophylaxis , which is used before the patient has been exposed to the infective agent.
If a true outbreak is discovered, infection control practitioners try to determine what permitted the outbreak to occur, and to rearrange the conditions to prevent ongoing propagation of the infection. Often, breaches in good practice are responsible, although sometimes other factors (such as construction) may be the source of the problem.
The topspin shot (also called a topspinner) is primarily used by racket sport players as either a "safe shot" or rally ball, or it can also be used to construct a point. . For example, a player may hit three topspin shots crosscourt, and then on the fourth shot hit a flat ball or a slice down the line to set him/herself up to win the po
In sports, topspin is a property of a shot where the ball rotates as if rolling in the same direction as it is moving. Topspin or Top Spin may also refer to: Top Spin, a 2014 documentary on Olympic athletes; Top Spin, a 2003 tennis video game
Follow, sometimes called top spin or simply "top," is spin in the direction of travel of the cue ball, so that it is spinning faster than it would from its natural roll. If the cue ball has top spin on it, it will resume rolling forward after making contact dead-on with the object ball and "follow" the object ball rather than stopping abruptly.
[2] In golf, a well-struck shot will result in a large amount of backspin that will carry the ball higher into the air and further. [ 3 ] Backspin will also help with distance control and, if there is enough backspin, the ball will "check" if it lands on the putting surface, and sometimes even creep backwards (in the opposite direction that the ...
After infection, immunity to the same strain of the virus – the genotype – protects against reinfection for six months to two years. [54] This immunity does not fully protect against infection with the other diverse genotypes of the virus. [54] In Canada, norovirus is a notifiable disease. [55] In both the US and the UK it is not notifiable ...
