Since 2012, an outbreak of Middle East respiratory syndrome coronavirus has affected several countries, primarily in its namesake, the Middle East. The virus, which causes Middle East respiratory syndrome (MERS), is a newly emerged betacoronavirus that was first identified in a patient from Saudi Arabia in April 2012. Sporadic cases, small clusters, and large outbreaks have been reported in 24 countries, with over 1000 cases of the virus and over 400 deaths. ==Coronavirus== Most infections with human coronaviruses are mild and associated with common colds. The six coronaviruses known to infect humans are in the alpha and beta genera. Both MERS-CoV and SARS-CoV (severe acute respiratory syndrome) are betacoronaviruses.〔 Global surveillance of potential epidemics and preparation has improved since and because of the SARS epidemic, and MERS is being closely monitored.〔As noted in the article published in ''The Economist'' on 20 April 2013, ProMED is an online reporting programme at the International Society for Infectious Diseases, part of improved surveillance systems that "use a range of sources to provide quick information on emerging threats" that were not available at the time of the SARS outbreak (in 2003), H5N1 bird flu (in 2005) and H1N1 swine flu (in 2009).〕 The Fourth Meeting of the International Health Regulations Emergency Committee concerning MERS-CoV was held on 4 December 2013. The committee decided that the conditions for a Public Health Emergency of International Concern (PHEIC) had not at present been met. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「2012 Middle East respiratory syndrome coronavirus outbreak」の詳細全文を読む スポンサード リンク
