Cholera outbreaks and pandemics
That year, cholera was transmitted along the California, Mormon and Oregon Trails as 6,000 to 12,000 are believed to have died on their way to the California Gold Rush, Utah and Oregon in the cholera years of 1849–1855. It is believed more than 150,000 Americans died during the two pandemics between 1832 and 1849.
2013 Moore tornado
On the morning of May 21, the medical examiner's office incorrectly stated that 91 bodies of tornado victims had been received. This number was up from the earlier report of 51 bodies that were incorrectly stated as having been received. Upon the office's discovery that some victims were mistakenly counted twice due to communication errors made by Moore rescue response units that the bodies were admitted to area funeral homes (nearly all of the deceased were actually transported to the examiner's office in Oklahoma City), the actual number was revised downward and later confirmed at 24 tornado victims and two indirect victims. The first two deaths occurred in a house east of Briarwood Elementary School; one occurred near Santa Fe Avenue; seven occurred following a wall collapse at Plaza Towers Elementary; nine occurred within the neighborhoods mainly south of Plaza Towers Elementary; one occurred just east of Interstate 35; and one occurred in a home between Eastern Avenue and Bryant Avenue. A 90-year-old woman who suffered a fractured skull during the tornado later suffered a pair of strokes and died on August 5. On May 6, 2018, nearly five years after the tornado, a 14-year-old survivor who suffered posttraumatic stress disorder after losing seven of his friends at Plaza Towers Elementary School committed suicide. The 2013 Moore tornado was the deadliest tornado recorded in the U.S. since the Joplin, Missouri tornado that killed 158 people in May 2011.
