ABSTRACT
Background: The Khongor soum has 253.3 thousand hectare square meter land which is 77 percent of Darkhan aimag from that 31.2 thousand hectare square meter land is used for plantation purpose. 12% of population is kazak. In April 2007, environment and drinking water resource of Khongor soum was polluted by dilution sewage water. Since after this incidence population were complaining about health status. Purpose of this survey was to determine cancer and general mortality of soum population. There 2 objectives: 1. To verify cancer mortality and morbidity in Khongor soum, Darkhan2. To assess excess mortality of cancer in the Khongor soumMethods: Health secondary data of 2006-2009 of Health department of Darkhan-Uul aimag was used for the assessment. The information about cause of death, number of death, population and so on were collected to caluculate crude mortality and cancer-specific mortality.Results: in 2007, the lowest or 4950 population was registered in Khongor soum and the highest number or 5628 of population was registered in 2002. The number of population gradually increased in 2009 by 5603. During 2006-2009 66 people were died in Khongor soum and this means 125.3 populations per 10000. According to the year trend mortality (66) rate was not fluctuated year by year. The leading ten causes of mortality of Khongor soum, at the first CVD (51.1 per 10000) and at the second cancer (37.8 per 10000) and it is similar with Mongolian mortality consistence. According to standardized mortality rate, mortality of Darkhan-Uul aimag was 8 per 10000 and the level of Khongor soum was 0.3 which means less than state average level. During 2006-2009 years, 24 people were died due to cancer and most of them were male (17, 70.8%). Every year of surveyed time, male mortality rate was high. The registered cancer (62.5 per 10000) of soum was similar with state average level and 1.5 times less then Darkhan- Uul aimag (92.5 per 1000) level.Conclusions: The last 5 years mortality rate of Khongor soum (124.9 per 10000) less 2.4 times from Mongolian state average level and 1.9 times less than Darkhan-uul aimag level. There are approved that cancer level of Khongor soum was not increased in last year. However, it is recommended to monitor Khongor soum’s morbidity and mortality to evaluate long-term effect of environmental pollution.
ABSTRACT
BACKGROUND: In Ulaanbaatar, the first case of the pandemic influenza infection has been reported on 12 October 2010.By November 9, a total of 929 cases laboratory-confirmed had been reported to National Center for CommunicableDiseases (NCCD). Of these cases reported, 9 people died.METHODS: The objectives of the study were to describe patients who admitted and hospitalized at NCCD and to determineoverall attack rates among health workers, secondary attack rates among students of colleges and universities. Datawas analyzed using Epi-Info2000.RESULTS: Among 929 of laboratory-confirmed cases, 50.3% (95% CI 43.0-57.5) were males aged 23 (±14.9) in averagewith youngest – 7 months, oldest – 76 years old. Data analysis by districts among the hospitalized patients, showed32.8% (139) of total cases in Bayanzurkh district including the first case of the pandemic influenza infection. The majorityof patients who admitted and hospitalized to NCCD mostly experienced fever (288, 68.1%), dry cough (251, 59.3%),headache (203, 48.0%), sore throat (175, 41.6%). With 1020 physicians and health workers in total, 41.4% (422) ofthem work at NCCD, 35.4% (361) – at MCHRC. 11.1% of health workers out of total become ill with pandemic H1N12009 (overall attack rate 11.1%) with the most common symptom, 380C and higher fever (100.0%, 113), sore throat(83.2%, 94), cough (76.1%, 86) and runny nose (59.3%, 67). The higher attack rates of health workers by occupationwere doctor (18.0%) and auxiliary (13%). The secondary attack rates among university students for influenza-likeillness(ILI) were 12.9%. These secondary attack rates were higher among students of art’s college as compared withother universities (52.4%). For students, the main clinical symptoms were fever + sore throat (75.0%, 18), fever+ cough(70.8%, 17).DISCUSSION: In China, as of 27 September, 2009, from reported total 19981 cases infected with pandemic influenza,61.0% were males, mean age was 17, mainly affected with 83% school students that consistent with our study result.The similar results on clinical symptoms were obtained in Russia. Out of 130 patients, 28.6% had 380Ñ and higherfever, for 54.3% the body temperature reached 38.1-390Ñ where as 17.1% - higher 390Ñ and 96% had cough, 89%had muscle ache, 65% had headache, 14% had diarrhea.
