Primary drug resistance of mycobacterium tuberculosis in Shandong, China, 2004-2018.

Background: Primary drug-resistant tuberculosis (DR-TB) has contributed to a significant health and economic burden on a global scale, especially in China. we sought to estimate epidemiological characteristics of primary DR-TB in China from 2004 to 2018.

Methods: Eleven thousand four hundred sixty-seven newly diagnosed and 1981 retreated TB cases with drug susceptibility data were included.

Ambient air pollution exposures and risk of drug-resistant tuberculosis.

Background: Few epidemiological studies have explored the effects of air pollution on the risk of drug-resistant tuberculosis (DR-TB).

Objective: To investigate the short and long term residential concentrations of ambient air pollutants (particulate matter <10 μm in diameter (PM) and particulate matter≤2.5 μm in diameter (PM), nitrogen dioxide (NO), sulfur dioxide (SO), ozone (O), and carbon monoxide (CO)) in relation to the risk of DR-TB in a typical air pollution city, Jinan city, China.

Occupational Carbon Monoxide Poisoning Associated with Diesel Motor Operation in an Air-raid Shelter in June 2015, Jinan City, China-An Epidemiological Investigation.

Occupational carbon monoxide (CO) poisoning related to diesel motor fumes in an air-raid shelter (ARS) was first identified in Jinan City, China, in June 2015. A total of 17 cases were identified, including 14 possible cases of firemen and 3 confirmed cases of water channel clean-up workers. The overall attack rate (AR) of firemen was 42% (14/33).

Ambient air pollution, smog episodes and mortality in Jinan, China.

We aimed to assess the acute effects of ambient air pollution and weather conditions on mortality in the context of Chinese smog episodes. A total of 209,321 deaths were recorded in Jinan, a large city in eastern China, during 2011-15. The mean concentrations of daily particulate matter ≤10 μm (PM), fine particulate matter (PM), sulfur dioxide (SO) and nitrogen dioxide (NO) were 169 μg/m, 100 μg/m, 77 μg/m, and 54 μg/m, respectively.

[A cross-sectional survey on the prevalence of Brucellosis among workers in Jiangsu province, 2012].

Objective: To study the status of infection and risk factors on Brucellosis among workers in Jiangsu province so as to provide related preventive and control measures.

Methods: A cross-sectional survey was conducted on 238 workers at three butcheries, one trading market and one stockyard. Related risk factors on the different exposures to the disease were also analyzed.

Investigation of an outbreak of cutaneous anthrax in Banlu village, Lianyungang, China, 2012.

Objective: After notification of a suspected case of anthrax following the slaughtering of a sick cow in Banlu village, an area that has not had any anthrax cases for decades, we aimed to confirm the outbreak, determine the transmission mechanism and implement control measures.

Methods: The outbreak response team interviewed all people that had contact with the sick cow. Three types of cases' specimens were collected and tested by blood smear, real-time polymerase chain reaction (PCR) and the gold colloid method.

[A viral meningitis outbreak associated with Echo30 in drinking water].

Objective: To study the source of infection, the scope of epidemic and control measures in an outbreak involving students having symptoms as fever, dizziness, headache, vomiting and nausea.

Methods: The suspected-case was defined as fever (armpit temperature ≥ 37°C) and with one or more of the following symptoms: dizziness, headache, vomiting and nausea, among students and teachers at school from Mar 1, 2012. Confirmed-case was among suspected case accompanied by both throat and rectal swabs enterovirus positive by RT-PCR.
