1918 flu pandemic

The 1918 flu pandemic (January 1918 – December 1920) was an unusually deadly influenza pandemic, the first of the two pandemics involving H1N1 influenza virus. It infected 500 million people across the world, including remote Pacific islands and the Arctic, and resulted in the deaths of 50 to 100 million (three to five percent of the world's population), making it one of the deadliest natural disasters in human history.

Most influenza outbreaks disproportionately kill juvenile, elderly, or already weakened patients; in contrast, the 1918 pandemic predominantly killed previously healthy young adults. Modern research, using virus taken from the bodies of frozen victims, has concluded that the virus kills through a cytokine storm (overreaction of the body's immune system). The strong immune reactions of young adults ravaged the body, whereas the weaker immune systems of children and middle-aged adults resulted in fewer deaths among those groups.

Historical and epidemiological data are inadequate to identify the pandemic's geographic origin. It was implicated in the outbreak of encephalitis lethargica in the 1920s.

2009 flu pandemic

The 2009 flu pandemic or swine flu was an influenza pandemic, and the second of the two pandemics involving H1N1 influenza virus (the first of them being the 1918 flu pandemic), albeit in a new version. First described in April 2009, the virus appeared to be a new strain of H1N1 which resulted when a previous triple reassortment of bird, swine and human flu viruses further combined with a Eurasian pig flu virus, leading to the term "swine flu". Unlike most strains of influenza, H1N1 does not disproportionately infect adults older than 60 years; this was an unusual and characteristic feature of the H1N1 pandemic. Even in the case of previously very healthy people, a small percentage will develop pneumonia or acute respiratory distress syndrome (ARDS). This manifests itself as increased breathing difficulty and typically occurs 3–6 days after initial onset of flu symptoms. The pneumonia caused by flu can be either direct viral pneumonia or a secondary bacterial pneumonia. In fact, a November 2009 New England Journal of Medicine article recommends that flu patients whose chest X-ray indicates pneumonia receive both antivirals and antibiotics. In particular, it is a warning sign if a child (and presumably an adult) seems to be getting better and then relapses with high fever, as this relapse may be bacterial pneumonia.

She Wolf

She Wolf (Spanish: Loba) is the eighth studio album by Colombian singer-songwriter Shakira. It was released on 9 October 2009, by Epic Records and Sony Music Latin. As executive producers, Shakira and Amanda Ghost enlisted collaborators including The Neptunes, John Hill, Wyclef Jean, Lukas Burton, Future Cut, Jerry Duplessis and Timbaland. Musically, the record shifts from her traditional Latin pop and pop rock musical styles, instead exploring electropop, with influences of folk and world music. The lyrical themes of the album mostly focus on love and relationships and were based on the conversations Shakira had with her friends.

She Wolf reached number one on the charts of Argentina, Ireland, Italy, Mexico and Switzerland. It also charted inside the top five in Spain, Germany and the United Kingdom. It debuted at number fifteen on the Billboard 200. She Wolf was certified double-platinum in Colombia and Mexico, platinum in Italy and Spain, and gold in numerous countries including France and the United Kingdom.

Philosophical movement

A philosophical movement is either the appearance or increased popularity of a specific school of philosophy, or a fairly broad but identifiable sea-change in philosophical thought on a particular subject. Major philosophical movements are often characterized with reference to the nation, language, or historical era in which they arose.

Talk of a philosophical movement can often function as a shorthand for talk of the views of a great number of different philosophers (and others associated with philosophy, such as historians, artists, scientists and political figures). On the other hand, most philosophical movements in history consisted in a great number of individual thinkers who disagreed in various ways; it is often inaccurate and something of a caricature to treat any movement as consisting in followers of uniform opinion. More often the defining ideas of any philosophical movement are templates on which individual thinkers develop their own particular ideas.
