“…The incidence rates of RIDs was negatively associated with per capita disposable income. These results were consistent with the findings reported in the literature (Lee et al, 2017; Yang, Zhou & Pan, 2017). In controlling infectious diseases, not only microbiological and environmental factors but also the impacts of population composition, economic and personal hygiene habits on diseases should be considered.…”

“…Undernutrition can weaken the function of the immune system and activate latent TB infection, and the occurrence of TB may lead to increased metabolism and decreased appetite, which can aggravate malnutrition. Additionally, Yuexi is located in a high-altitude area and experienced more natural disasters, which were risk factors for TB incidence (Yang, Zhou & Pan, 2017).…”

Background Natural disasters can indirectly induce epidemics of infectious diseases through air and water pollution, accelerated pathogen reproduction, and population migration. This study aimed to explore the epidemiological characteristics of the main infectious diseases in Sichuan, a province with a high frequency of natural disasters. Methods Data were collected from the local Centers for Disease Control infectious disease reports from Lu, Shifang and Yuexi counties from 2011 to 2015 and from the baseline survey of the Disaster Mitigation Demonstration Area in Western China in 2016. Principal component regression was used to explore the main influencing factors of respiratory infectious diseases (RIDs). Results The incidence rates of RIDs and intestinal infectious diseases (IIDs) in 2015 were 78.99/100,000, 125.53/100,000, 190.32/100,000 and 51.70/100,000, 206.00/100,000, 69.16/100,000 in Lu, Shifang and Yuexi respectively. The incidence rates of pulmonary tuberculosis (TB) was the highest among RIDs in the three counties. The main IIDs in Lu and Shifang were hand-foot-mouth disease (HFMD) and other infectious diarrhea; however, the main IIDs in Yuexi was bacillary dysentery. The proportions of illiterate and ethnic minorities and per capita disposable income were the top three influencing factors of RIDs. Conclusions TB was the key point of RIDs prevention among the three counties. The key preventable IIDs in Lu and Shifang were HFMD and other infectious diarrhea, and bacillary dysentery was the major IIDs in Yuexi. The incidence rates of RIDs was associated with the population composition, the economy and personal hygiene habits.

“…In addition, the hot spot areas are inhabited by minorities, especially the Zhuang ethnic group, while the cold spot areas are inhabited mainly by the Han population (China’s main ethnic group). Some parts of China have reported a higher prevalence of TB in ethnic minority areas compared to areas where a majoring of the population are Han [6]. With this background, we have considered ethnicities as a potential risk factor in this study.…”

The aims of the study were: (1) compare sociodemographic characteristics among active tuberculosis (TB) cases and their household contacts in cold and hot spot transmission areas, and (2) quantify the influence of locality, genotype and potential determinants on the rates of latent tuberculosis infection (LTBI) among household contacts of index TB cases. Parallel case-contact studies were conducted in two geographic areas classified as “cold” and “hot” spots based on TB notification and spatial clustering between January and June 2018 in Guangxi, China, using data from field contact investigations, whole genome sequencing, tuberculin skin tests (TSTs), and chest radiographs. Beijing family strains accounted for 64.6% of Mycobacterium tuberculosis (Mtb) strains transmitted in hot spots, and 50.7% in cold spots (p-value = 0.02). The positive TST rate in hot spot areas was significantly higher than that observed in cold spot areas (p-value < 0.01). Living in hot spots (adjusted odds ratio (aOR) = 1.75, 95%, confidence interval (CI): 1.22, 2.50), Beijing family genotype (aOR = 1.83, 95% CI: 1.19, 2.81), living in the same room with an index case (aOR = 2.29, 95% CI: 1.5, 3.49), travelling time from home to a medical facility (aOR = 4.78, 95% CI: 2.96, 7.72), history of Bacillus Calmette-Guérin vaccination (aOR = 2.02, 95% CI: 1.13 3.62), and delay in diagnosis (aOR = 2.56, 95% CI: 1.13, 5.80) were significantly associated with positive TST results among household contacts of TB cases. The findings of this study confirmed the strong transmissibility of the Beijing genotype family strains and this genotype’s important role in household transmission. We found that an extended traveling time from home to the medical facility was an important socioeconomic factor for Mtb transmission in the family. It is still necessary to improve the medical facility infrastructure and management, especially in areas with a high TB prevalence.

“…Thus, although TCPS didn't mitigate TB but still it kept the epidemiologic situation stable. An epidemiological study of Yang et al showed the tuberculosis incidence and related burden was decreased in wenchuan earthquake-stricken area from 2004-2012 [24]. Lin et al in a study on TB mortal cases showed that patients with inappropriate organ function were in the risk of septicemia and fatality [25].…”

Introduction: Tuberculosis (TB) is known as an infectious disease with high burden from a long time. Various strategies are implemented to control its spread in the world and this study is to evaluate Tuberculosis Control Program in Sistan. Methods: For this purpose we collected data with the methods of questionnaires, checklists, interviews, documentation review and observation. Using these methods together with data collection will boost the advantages of each single method. Data analyzed by using SPSS-18 software. We considered differences as significant at the level of P < 0.05. Results: Effectiveness and Cost-Benefit considered as the priorities of TCPS evaluation. Current study showed TCPS reduced delayed time between case detection and treatment initiation to less than one week. TB incidence was 96 and 107 per 100,000 of population respectively in 2011 and 2012 i.e. one year before and after TCPS implementation. It increased case detection but SPSS Kruskal Wallis test showed there was not a significant change according to TCPS implementation (P > 0.05). It didn't have a significant change in patient destiny after implementation. From the each dollar we spend in TCPS implementation (COST), about 0.86 dollar was saved. Conclusions: The reason why TCPS is not fully successful is because either the TB infected contacts were not screened or due to TCPS deviation from world health organization procedures. Current study showed from the each dollar we spend in TCPS implementation, about 0.86 dollar was saved.
