{{B}} Slater{{/B}} Swine influenza (also called swine
flu, hog flu, and pig flu) refers to influenza caused by those strains of
influenza virus, called swine influenza virus (SIV), that usually infect pigs.
Swine influenza is common in pigs in the Midwestern United States (and
occasionally in other states), Mexico, Canada, South America, Europe (including
the United Kingdom, Sweden, and Italy), Kenya, Mainland China, Taiwan, Japan and
other parts of eastern Asia.{{B}} Mike Smith{{/B}}
Transmission of swine influenza virus from pigs to humans is not common
and properly cooked pork poses no risk of infection. When transmission results
in influenza in a human, it is called zoonotic swine flu. People who work with
pigs, especially people with intense exposures, are at risk of catching swine
flu. Rarely, these strains of swine flu can pass from human to human. In humans,
the symptoms of swine flu are similar to those of influenza and of
influenza-like illness in general, namely chills, fever, sore throat, muscle
pains, severe headache, coughing, weakness and general discomfort.{{B}}
Baker{{/B}} The 2009 flu outbreak in humans, known as "swine
flu", is due to a new strain of influenza A virus subtype H1N1 that contained
genes most closely related to swine influenza. The origin of this new strain is
unknown, however, and the World Organization for Animal Health (OIE) reports
that this strain has not been isolated in pigs. This strain can be transmitted
from human to human, and causes the normal symptoms of influenza.{{B}}
Bob David{{/B}} If a person becomes sick with swine flu,
antiviral drugs can make the illness milder and make the patient feel better
faster. They may also prevent serious flu complications. For treatment,
antiviral drugs work best if started soon after getting sic (within 2 days of
symptoms). Beside antivirals, palliative care, at home or in hospital, focuses
on controlling fevers and maintaining fluid balance. However, the majority of
people infected with the virus make a full recovery without requiring medical
attention or antiviral drugs.{{B}} Tom Brown{{/B}} In the
US, on April 27, 2009, the FDA issued Emergency Use Authorizations to make
available Relenza and Tamiflu antiviral drugs to treat the swine influenza virus
in cases for which they are currently unapproved. The agency issued these EUAs
to allow treatment of patients younger than the current approval allows and to
allow the widespread distribution of the drugs, including by non-licensed
volunteers.{{I}} Now match each of the persons to the appropriate
statement. Note: there are two extra statements.{{/I}}{{B}}

Canada, South Africa, Europe, Kenya, Mainland China, Taiwan, Japan and other

Under Social Darwinism the lazy and the (27) were supposed to be at the bottom of the economic ladder as a result of the "law of (28) of the fittest". Society was (29) as a network of self-sufficient families which provided for their own. (30) persons outside a household (orphans, the (31) elderly,and the crippled) were provided outdoor relief grudgingly and as a temporary expedient. Although it was (32) that "the poor will always be with us", the individual was expected to improve himself (33) acts of his own will. Charity was thought to be the (34) of idleness. By keeping wages low, labourers would be (35) to work harder. At about the turn of the century, the beginning of concern about natural (36) brought uneasiness about the possible spread of beggary. There was a potentially dangerous class in (37) of disease and disorder. The "poor" were (38) as different from "paupers". Paupers were individuals well (39) to being on the low end of the socioeconomic (40) . Without shame or bitterness, they would not seek independence and a " (41) " life.

In (43) ,the worthy poor struggled to (44) their lot against circumstances beyond their control: low wages, sickness, industrial (45) , widowhood and so on.
