Every home, school, and place of business should have an effective tornado preparedness plan in advance of a tornado alert, and tornado drills should be considered. Earlier that afternoon, in another case of 1999 deja vu, a separate EF3 tornado tore through parts of Bridge Creek, Oklahoma, damaging dozens of homes. %%EOF In fact, policy statements supporting modification of guidelines involving motor vehicles have been issued (20). However, since mobile homes and their contents were more often totally destroyed, the proportion of mobile home residents available for interview during our community survey probably was smaller than the proportion of house residents. Proportionally more females than males were injured (55% and 45%, respectively). Brown, S., P. Archer, E. Kruger, and S. Mallonee, 2002: Tornado-Related Deaths and Injuries in Oklahoma due to the 3 May 1999 Tornadoes. Almost three-fourths (376/512) of survivors were treated in an emergency department and released, and 134 (26%) persons were admitted to a hospital. Two outpatient cases indirectly related to the tornadoes involved motor vehicle collisions among people fleeing the tornado for shelter. Older people in a tornado's path are also at greater risk (3). The public health consequences of disasters. Three more tornadoes were spawned in the Oklahoma City metro area the evening of May 9, 2003, including an F3 tornado tracking from south of Edmond to near Luther, Oklahoma, a path of 18 miles. One of the tornadoes that tracked through the Oklahoma City metropolitan area reached F5 intensity in heavily populated areas. As it turned out, thunderstorms did form west of the Oklahoma City metro area in mid-afternoon. Including May 3, 1999, there have been 45 tornadoes in the Oklahoma City metro area through 2016, an average of two to three tornadoes each year. Washington, DC: Bureau of the Census, US Department of Commerce. Risk of severe injury was also greater for persons in mobile homes (OR = 11.8, 95% CI: 3.4, 51.7) or outdoors (OR = 34.3, 95% CI: 4.4, 1,526.2). 2). A total of 56 tornadoes were observed in Oklahoma that afternoon. To understand how this event fits into the historical context, the record of tornado deaths in the United States has been examined. Almost 20 000 deaths have been reported associated with more than 3600 tornadoes in the United States since 1680. Warning systems should be integrated and duplicative, and they should include traditional methods and new technology. Direct tornado deaths result from multiple injuries, head injuries, chest injuries, crush injuries, asphyxia, and heart attacks (Bohonos and Hogan 1998; CDC 1997a,b; Glass et al. With the rapid influx of patients, medical personnel were not able to obtain and record detailed notes in the patients' records, especially when the injuries were minor. Numerous studies have reported higher rates of death and serious injury associated with being inside mobile homes (CDC 1997b; Eidson et al. A statistical association was found if the null hypothesis was rejected and the two proportions were found to be statistically different at p value < 0.05, that is, statistically significant. In 1875, a large increase in the number of reports in the record occurred, with 30 killer tornadoes in that year alone. The result is that the probability of such a gap is less than 1 in 3000. Odds ratio for death or injury at the specified haven, as compared with other rooms in a house. This study was supported in part by funding from the Federal Emergency Management Agency and the Centers for Disease Control and Prevention. Probable causes of death included multiple injuries (50%), head injuries (23%), chest trauma (18%), and traumatic asphyxia (10%). The age is unknown for 45 persons, and the sex is unknown for 2 persons Four hundred thirty-six injuries were recorded for persons who died (average 11 injuries per person). To do so, we randomly select 36 ages from the distribution associated with the 1990s, and repeat for a large number of trials. 4). Thirty-six people were killed as a direct result of the storm and five more died of indirect causes in the hours following it; most of the indirect deaths were due to heart attacks or injuries suffered while trying to seek shelter. The smoother consists of finding the median of three consecutive values and then applying a running mean over five medians. The anonymous reviewers provided helpful suggestions for improving the presentation. In all surveys, persons reported receiving one or more warnings. Since weak tornadoes were not always documented prior to 1950, this number is likely well underestimated, according to NWS. Location at the time of injury could not be determined for six victims with severe injuries, 34 victims with minor injuries, and four controls.
