On May 29, 2015 (April 12, 2015 in the lunar calendar), the first case of imported Middle East Respiratory Syndrome (MERS) was diagnosed. Middle East Respiratory Syndrome (MERS) According to a report from the National Health and Family Planning Commission on May 29, 2015, the first confirmed case of imported Middle East Respiratory Syndrome occurred in Huizhou City, Guangdong Province. The patient was a close contact of the confirmed case in South Korea. Faced with the confirmation of the first imported case of Middle East Respiratory Syndrome in China, I hope that everyone can learn more about the epidemiology, demography, clinical characteristics, and laboratory test results of this disease, and strive to know ourselves and our enemy, actively prevent it, and face it calmly. As of May 25, 2015, according to data released by the World Health Organization (WHO), there were a total of 1139 laboratory-confirmed cases of MERS-CoV infection (referred to as MERS) worldwide, of which 431 cases died (case fatality rate 37.8%). These cases come from 24 countries and regions, with the largest number of cases being Saudi Arabia. Most of the cases are concentrated in the Middle East such as Saudi Arabia and United Arab Emirates. Most confirmed cases in countries outside this region have a history of work or tourism in the Middle East before the onset. Descriptive Medical Research Paper on Clinical Characteristics of Middle East Respiratory Syndrome The largest case study comes from a report by Professor Abdullah Assiri and others in the 2013 Lancet magazine. The author summarized and analyzed the epidemiological, demographic and clinical characteristics of 47 laboratory-confirmed cases of MERS in detail. From September 1, 2012 to June 15, 2013, 47 cases of MERS confirmed by laboratory RT-PCR from Saudi Arabia had an average incubation time of 5.2 days, and 95% of patients developed symptoms within approximately 12 days. Relationship between demographic characteristics and case fatality rate: Of the 47 laboratory-confirmed cases of MERS, 46 were adults and 1 was a child. 36 cases were male (77%), with a male to female ratio of 3.3:1. There was no significant difference in the case fatality rate between men and women (61% versus 55%). 28 patients died, with a case fatality rate of 60%. The case fatality rate increased with age. The case fatality rate among people less than 50 years old was 39%(13/27), while that among people over 60 years old reached 75%(15/20).
