An overview of tuberculosis outbreaks reported in the years 2011-2020.

ABSTRACT:

Background

In many countries tuberculosis (TB) remains a highly prevalent disease and a major contributor to infectious disease mortality. The fight against TB requires surveillance of the population of strains circulating worldwide and the analysis of the prevalence of certain strains in populations. Nowadays, whole genome sequencing (WGS) allows for accurate tracking of TB transmission. Currently, there is a lack of a comprehensive summary of the characteristics of TB outbreaks.

Methods

We systematically analyzed studies reporting TB outbreaks worldwide, monitored through WGS of Mycobacterium tuberculosis. We 1) mapped the reported outbreaks from 2011- 2020, 2) estimated the average size of the outbreaks, 3) indicated genetic lineages causing the outbreaks, and 4) determined drug-resistance patterns of M. tuberculosis strains involved in the outbreaks.

Results

Most data originated from Europe, Asia, and North America. We found that TB outbreaks were reported throughout the globe, on all continents, and in countries with both high and low incidences. The detected outbreaks contained a median of five M. tuberculosis isolates. Most strains causing the outbreaks belonged to lineage four, more rarely to lineage two. Reported outbreak isolates were often drug resistant.

Conclusions

We conclude that more WGS surveillance of M. tuberculosis outbreaks is needed. Globally standardized procedures might improve the control of M. tuberculosis infections.

Project description:Fecal contamination of water sources and open defecation have been linked to cholera outbreaks in India. However, a systematic review on the drivers responsible for these outbreaks has yet to be published. Here, we systematically review the published literature on cholera outbreaks in India between 2011 and 2020. We searched studies in English in three databases (MEDLINE, EMBASE, and Web of Science) and the Integrated Disease Surveillance Program that tracks cholera outbreaks throughout India. Two authors independently extracted data and assessed the quality of the included studies. Quantitative data on the modes of transmission reviewed in this study were assessed for any change over time between 2011-2015 and 2016-2020. Our search retrieved 10823 records initially, out of which 81 full-text studies were assessed for eligibility. Among these 81 studies, 20 were eligible for inclusion in this review. There were 565 reported outbreaks between 2011 and 2020 that led to 45,759 cases and 263 deaths. Outbreaks occurred throughout the year; however, they exploded with monsoons (June through September). In Tamil Nadu, a typical peak of cholera outbreaks was observed from December to January. Seventy-two percent (33,089/45,759) of outbreak-related cases were reported in five states, namely Maharashtra, West Bengal, Punjab, Karnataka, and Madhya Pradesh. Analysis of these outbreaks highlighted the main drivers of cholera including contaminated drinking water and food, inadequate sanitation and hygiene (including open defecation), and direct contact between households. The comparison between 2011-2015 and 2016-2020 showed a decreasing trend in the outbreaks that arose due to damaged water pipelines. Many Indians still struggle with open defecation, sanitation, and clean water access. These issues should be addressed critically. In addition, it is essential to interrupt cholera short-cycle transmission (mediated by households, stored drinking water and foodstuffs) during an outbreak. As cholera is associated with deprivation, socio-economic development is the only long-term solution.

Project description:BackgroundTuberculosis (TB) poses a severe public health challenge in China and worldwide. This study evaluated the effects of age, period, and birth cohort on reported incidence trends of TB based on population and refined the characteristics of high-risk groups.MethodsAggregate data that reported pulmonary tuberculosis (PTB) cases from China Tuberculosis Management Information System (TBIMS) from 2006 to 2020 were used to analyze effect coefficients through the age-period-cohort (APC) model based on intrinsic estimator (IE) method, and converted them into relative risk (RR) to estimate trends.ResultsA total of 14.82 million cases of PTB were reported in China from 2006 to 2020, showing a continuous downward trend. The reporting rate increased with age by age group, with 70-74 years old being 2-3 times higher than that in 20-24 years old. APC analysis model showed that age effects were bimodal in 20-24 years old [RR = 2.29, 95% confidence interval (CI): 1.73-3.03] and 70-74 years old (RR = 1.95, 95% CI: 1.67-2.27), and lower than the overall average in the groups under 15 years old. Stratified results showed that the risk was higher for women under age 40 than men and higher for men over 40. The risk was higher in urban than in rural areas under 30 years old and slightly higher in rural than in urban between 30 and 64 years old. The risk for 15-34 years old was significantly higher in the east than in other regions. The period effects showed a decreasing trend, and the risk was higher in rural in recent years. Except for cohorts born in 1961-1965 and 2001-2005, where the RR increased, the later the cohort was born, the lower the risk. The cohort 1926-1930 in eastern had the highest risk (RR = 3.49, 95% CI: 2.44-4.98).ConclusionsThe reported incidence of PTB continued to decline in China from 2006 to 2020. The young (20-24 years old) and the elderly (70-74 years old) were equally at high risk. There were differences in the age, period and cohort effects on PTB incidence among gender, urban-rural and regions. Our findings better reflected the characteristics of high-risk populations, thus contributing to the development of timely and effective intervention strategies, and providing clues for etiological research.

Project description:BackgroundRifampicin (RIF) is a key first-line drug used to treat tuberculosis, a primarily pulmonary disease caused by Mycobacterium tuberculosis. RIF resistance is caused by mutations in rpoB, at the cost of slower growth and reduced transcription efficiency. Antibiotic resistance to RIF is prevalent despite this fitness cost. Compensatory mutations in rpoABC genes have been shown to alleviate the fitness cost of rpoB:S450L, explaining how RIF resistant strains harbor this mutation can spread so rapidly. Unfortunately, the full set of RIF compensatory mutations is still unknown, particularly those compensating for rarer RIF resistance mutations.ObjectivesWe performed an association study on a globally representative set of 4,309 whole genome sequenced clinical M. tuberculosis isolates to identify novel putative compensatory mutations, determine the prevalence of known and previously reported putative compensatory mutations, and determine which RIF resistance markers associate with these compensatory mutations.Results and conclusionsOf the 1,079 RIF resistant isolates, 638 carried previously reported putative and high-probability compensatory mutations. Our strict criteria identified 46 additional mutations in rpoABC for which no strong prior evidence of their compensatory role exists. Of these, 35 have previously been reported. As such, our independent corroboration adds to the mounting evidence that these 35 also carry a compensatory role. The remaining 11 are novel putative compensatory markers, reported here for the first time. Six of these 11 novel putative compensatory mutations had two or more mutation events. Most compensatory mutations appear to be specifically compensating for the fitness loss due to rpoB:S450L. However, an outbreak of 22 closely related isolates each carried three rpoB mutations, the rare RIFR markers D435G and L452P and the putative compensatory mutation I1106T. This suggests compensation may require specific combinations of rpoABC mutations. Here, we report only mutations that met our very strict criteria. It is highly likely that many additional rpoABC mutations compensate for rare resistance-causing mutations and therefore did not carry the statistical power to be reported here. These findings aid in the identification of RIF resistant M. tuberculosis strains with restored fitness, which pose a greater risk of causing resistant outbreaks.

Project description:BackgroundCommunity-based initiatives (CBIs) on childhood obesity are considered a good practice approach against childhood obesity. The European Commission called for an overview of CBIs implemented from 2005-2011. A survey was executed by the National Institute for Public Health and the Environment of the Netherlands, in collaboration with the World Health Organization Regional Office for Europe. The objective of this paper is to provide an overview of the European CBIs, as identified in the survey, presenting their general characteristics, applied strategies (separately for actions targeting the environment and/or directly the children's behaviour) and the reported effects on weight indicators.MethodsPotentially eligible CBIs were identified by informants in 27 European Union countries, Iceland, Liechtenstein, Norway, and Switzerland, and through desk research. School based approaches could be included if they complied with criteria related to being 'community-based'. In total, 278 potential eligible CBIs were identified and of these, 260 projects were approached. For 88 an electronic questionnaire was completed; of these 71 met all criteria. The included projects were reported by 15 countries.Results66% of the 71 CBIs implemented actions in more than one setting or throughout the neighbourhood. Most frequently reported environmental actions were professional training (78%), actions for parents (70%), and changing the social (62%) and physical (52%) environment. Most frequently reported educational activities were group education (92%), general educational information (90%), and counselling sessions (58%). The vast majority (96%) implemented both environmental and individual strategies and about half of the CBIs reported a public-private partnership. Eight CBIs provided evidence supporting positive effects on weight indicators and/or overweight prevalence in a general population of children (aged 6 to 12 yrs), and one CBI did not support this. Two of those CBIs were also conducted among adolescents (aged 12 to 16,5 yrs), but showed no effect in this age-group.ConclusionsDespite diversity of included CBIs, common characteristics were the application of integrated actions at a local level, aimed at changing the environment and the children's behaviour directly. Evidence supporting effectiveness on weight indicators is available, although the design and conduct of most of these studies were suboptimal (i.e. no control group, a small sample size, not random).
