On Saturday, September 21, 2013, members of Al Shabaab, a Somali based Islamic terrorist organization affiliated with the international Al Qaeda network, executed a complex terrorist attack on an upscale shopping mall in Nairobi, Kenya. The attackers simultaneously entered the mall from two different entrances, shooting shoppers with assault rifles and throwing hand grenades. The terrorists remained in the mall, engaging government security forces for the next four days, resulting in a major fire and partial collapse of the mall. The Kenyan government has officially reported 72 deaths and more than 200 injured as a result of the attack. A significant number of those killed and injured were foreign citizens, including 6 U.S. citizens who were injured in the attack.
From November through December 2013, CDC has received a number of reports of severe respiratory illness among young and middle-aged adults, many of whom were infected with influenza A (H1N1) pdm09 (pH1N1) virus. Multiple pH1N1-associated hospitalizations, including many requiring intensive care unit (ICU) admission, and some fatalities have been reported. The pH1N1 virus that emerged in 2009 caused more illness in children and young adults, compared to older adults, although severe illness was seen in all age groups. While it is not possible to predict which influenza viruses will predominate during the entire 2013- 14 influenza season, pH1N1 has been the predominant circulating virus so far. For the 2013-14 season, if pH1N1 virus continues to circulate widely, illness that disproportionately affects young and middle-aged adults may occur.
Hydrogen sulfide is considered a broad spectrum poison, meaning ‐ that it can poison several different systems in the body, although the nervous system is most affected. The toxicity of H2S is comparable with that of hydrogen cyanide. It forms a complex bond with iron in the mitochondrial cytochrome enzymes, thereby blocking oxygen from binding and stopping cellular respiration.
