ABSTRACT
Objective@#To analyse epidemiological, clinical characteristics and laboratory examination results of 245 occupational brucellosis form 2008 to 2018, which providing theoretical basis for prevention and control of occupational brucellosis.@*Methods@#Based on the China Center for Disease Control and Prevention Information System, a database of occupational brucellosis cases in HunlunBuir from January 2008 to July 2018 was established. The Epidemiological characteristics, Clinical manifestation, laboratory examination of 245 occupational brucellosis and 359 without occupational brucellosis were comparatively analyzed about the same period.@*Results@#Among the 245 patients, 219 were males, 254 in 359, malese were significantly higher than control group (χ2=21.331, P<0.05) . Fever, fatigue, hyperhidrosis and splenomegaly are common in patients with occupational brucellosis and non occupational brucellosis. Arthralgia (54.3%/44.8%) and CRP (81.2%/71.3%) were significantly also higher than control group (χ2=5.193, P<0.05; χ2=7.704, P<0.05) Fever, hyperhidrosis, fatigue and splenomegaly were common clinical manifestation and signs in the two groups. Brucellosis can cause a variety of complications, including osteoarticular hematological system and hepatic involvement, some patients with multiple system damage.@*Conclusion@#The incidence of occupational brucellosis in HulunBuir is concentrated in agriculture and animal husbandry. Veterinarians are the main occupational groups, Occupational health interventions should be strengthened for key occupational hazards, regular occupational health examination, avoid chronic brucellosis and protect the health of key occupational groups.
ABSTRACT
Objective@#To provide scientific evidence for Prevention and control measures of Occupational Forest Encephalitis (OFE) by analyzing the Epidemiological and occupational characteristics, clinical manifestation of OFE cases reported in HunlunBuir city during 2008~2017.@*Methods@#Based on the China Center for Disease Control and Prevention Information System, a database of OFE cases in HunlunBuir from 2008~2017 was established. The Epidemiological characteristics of OFE were analyzed including three distributions, the available information includes 291 cases of population, geographical, periods, occupational distribution, clinical manifestations and laboratory examinations.@*Results@#There were 291 OFE cases in HunlunBuir from 2008 to 2017, including 287 cases of mild OFE, Moderate, Serve in1, 3 cases, 282 male. In the temporal distribution, the most cases were 48 cases in 2011, 119 casesin June. 33.7% of the cases (98) were reported in Yakeshi, following 29.2% and 21.3% inroqen Autonomous Banner (85) , Genhe (62) . Of 291 cases, male were in 282.The high incidence of OFE mainly existed in Forest management 112 (38.5%) . The most clinical manifestation were headache in 195 (67%) , fever in 168 (57.7%) .@*Conclusion@#The distribution of Occupational Forest Encephalitis cases in diverse regions and months in HunlunBuir are quite different. The occupational safety precautions of the forest workers and tick-borne encephalitis vaccines should be strengthened to reduce the occurrence of Occupational Forest Encephalitis.
ABSTRACT
Objective@#To provide scientific evidence for the prevention and control measures of acute and chronic occupational poisoning by analyzing the epidemiological and occupational characteristics of occupational chemical poisoning cases reported in Tianjin city during 2006-2015.@*Methods@#In September 2016, based on the China Disease Control and Prevention Information System, a database of occupational poisoning cases in Tianjin from 2006 to 2015 was established. The epidemiological characteristics of occupational poisoning were analyzed including three distributions firstly, and then the occupational characteristics were analyzed such as length of service, industry distribution and source of poison.@*Results@#There were 174 occupational poisoning patients in Tianjin from 2006 to 2015, including 16 cases of acute poisoning (9.20%) and 158 cases of chronic poisoning (90.8%) , and the proportion of occupational poisoning cases reported in Binhai New Area is the highest. The number of reported cases of chronic occupational poisoning shows a downward trend. Occupational poisoning cases are concentrated mainly in the age of 40-60 years and length of service of 10-20 years. The high incidence of occupational poisoning mainly exists in the chemical raw materials and chemical manufacturing industry and general, professional equipment manufacturing industry. Acute poisoning was mainly by asphyxial gas (50.00%) , and chronic poisoning was mainly by organic solvent (43.67%) .@*Conclusion@#The distribution of occupational poisoning cases in diverse toxic types and regions in Tianjin are quite different. The occupational safety precautions of the chemical raw materials and chemical products manufacturing and occupational poisoning control work in Binhai new area should be strengthened to reduce the occurrence of occupational poisoning.
