Modeling The Effect Of Water, Sanitation, And Hygiene And Oral Cholera Vaccine Implementation In Haiti, Isaac Chun-Hai Fung, David L. Fitter, Rebekah H. Borse, Martin I. Meltzer, Jordan W. Tappero
Modeling The Effect Of Water, Sanitation, And Hygiene And Oral Cholera Vaccine Implementation In Haiti, Isaac Chun-Hai Fung, David L. Fitter, Rebekah H. Borse, Martin I. Meltzer, Jordan W. Tappero
Isaac Chun-Hai Fung
In 2010, toxigenic Vibrio cholerae was newly introduced to Haiti. Because resources are limited, decisionmakers need to understand the effect of different preventive interventions. We built a static model to estimate the potential number of cholera cases averted through improvements in coverage in water, sanitation and hygiene (WASH) (i.e., latrines, point-of-use chlorination, and piped water), oral cholera vaccine (OCV), or a combination of both. We allowed indirect effects and non-linear relationships between effect and population coverage. Because there are limited incidence data for endemic cholera in Haiti, we estimated the incidence of cholera over 20 years in Haiti by using …
How To Minimize The Attack Rate During Multiple Influenza Outbreaks In A Heterogeneous Population, Isaac Chun-Hai Fung, Rustom Antia, Andreas Handel
How To Minimize The Attack Rate During Multiple Influenza Outbreaks In A Heterogeneous Population, Isaac Chun-Hai Fung, Rustom Antia, Andreas Handel
Isaac Chun-Hai Fung
Background: If repeated interventions against multiple outbreaks are not feasible, there is an optimal level of control during the first outbreak. Any control measures above that optimal level will lead to an outcome that may be as sub-optimal as that achieved by an intervention that is too weak. We studied this scenario in more detail.
Method: An age-stratified ordinary-differential-equation model was constructed to study infectious disease outbreaks and control in a population made up of two groups, adults and children. The model was parameterized using influenza as an example. This model was used to simulate two consecutive outbreaks of the …
Interventions To Improve Excreta Disposal For Preventing Diarrhoea, Thomas F. Clasen, Kristof Bostoen, Wolf-Peter Schmidt, Sophie Boisson, Isaac Chun-Hai Fung, Marion W. Jenkins, Beth Scott, Steven Sugden, Sandy Cairncross
Interventions To Improve Excreta Disposal For Preventing Diarrhoea, Thomas F. Clasen, Kristof Bostoen, Wolf-Peter Schmidt, Sophie Boisson, Isaac Chun-Hai Fung, Marion W. Jenkins, Beth Scott, Steven Sugden, Sandy Cairncross
Isaac Chun-Hai Fung
Background: Diarrhoeal diseases are a leading cause of mortality and morbidity, especially among young children in low-income countries, and are associated with exposure to human excreta.
Objectives: To assess the effectiveness of interventions to improve the disposal of human excreta for preventing diarrhoeal diseases.
Search Strategy: We searched the Cochrane Infectious Disease Group Specialized Register; the Cochrane Central Register of Controlled Trials (CENTRAL), published in The Cochrane Library; MEDLINE; EMBASE; LILACS; the metaRegister of Controlled Trials (mRCT); and Chinese-language databases available under the Wan Fang portal, and the China National Knowledge Infrastructure (CNKI-CAJ). We also handsearched relevant conference proceedings, and …
Water, Sanitation And Hygiene For The Prevention Of Diarrhoea, Sandy Cairncross, Caroline Hunt, Sophie Boisson, Kristof Bostoen, Val Curtis, Isaac Chun-Hai Fung, Wolf-Peter Schmidt
Water, Sanitation And Hygiene For The Prevention Of Diarrhoea, Sandy Cairncross, Caroline Hunt, Sophie Boisson, Kristof Bostoen, Val Curtis, Isaac Chun-Hai Fung, Wolf-Peter Schmidt
Isaac Chun-Hai Fung
Background: Ever since John Snow's intervention on the Broad St pump, the effect of water quality, hygiene and sanitation in preventing diarrhoea deaths has always been debated. The evidence identified in previous reviews is of variable quality, and mostly relates to morbidity rather than mortality.
Methods: We drew on three systematic reviews, two of them for the Cochrane Collaboration, focussed on the effect of handwashing with soap on diarrhoea, of water quality improvement and of excreta disposal, respectively. The estimated effect on diarrhoea mortality was determined by applying the rules adopted for this supplement, where appropriate.
Results: The striking effect …
Chinese Journals: A Guide For Epidemiologists, Isaac Chun-Hai Fung
Chinese Journals: A Guide For Epidemiologists, Isaac Chun-Hai Fung
Isaac Chun-Hai Fung
Chinese journals in epidemiology, preventive medicine and public health contain much that is of potential international interest. However, few non-Chinese speakers are acquainted with this literature. This article therefore provides an overview of the contemporary scene in Chinese biomedical journal publication, Chinese bibliographic databases and Chinese journals in epidemiology, preventive medicine and public health. The challenge of switching to English as the medium of publication, the development of publishing bibliometric data from Chinese databases, the prospect of an Open Access publication model in China, the issue of language bias in literature reviews and the quality of Chinese journals are discussed. …
Citation Of Non-English Peer Review Publications – Some Chinese Examples, Isaac Chun-Hai Fung
Citation Of Non-English Peer Review Publications – Some Chinese Examples, Isaac Chun-Hai Fung
Isaac Chun-Hai Fung
Articles published in English language journals with citations of non-English peer reviewed materials are not very common today. However, as epidemiologists are becoming more aware of data and information being readily available and accessible in the non-English literature, the question of whether non-English materials can be cited in English language journals and if so, how should they be cited, has become an increasingly important issue. Bringing together personal insights from the author's familiarity with both the English and Chinese language epidemiological literature and results from a survey on the use of citations of non-English peer reviewed materials across a sample …
Seek, And Ye Shall Find: Accessing The Global Epidemiological Literature In Different Languages, Isaac Chun-Hai Fung
Seek, And Ye Shall Find: Accessing The Global Epidemiological Literature In Different Languages, Isaac Chun-Hai Fung
Isaac Chun-Hai Fung
The thematic series 'Beyond English: Accessing the global epidemiological literature' in Emerging Themes in Epidemiology highlights the wealth of epidemiological and public health literature in the major languages of the world, and the bibliographic databases through which they can be searched and accessed. This editorial suggests that all systematic reviews in epidemiology and public health should include literature published in the major languages of the world and that the use of regional and non-English bibliographic databases should become routine.

Does Language Matter? A Case Study Of Epidemiological And Public Health Journals, Databases And Professional Education In French, German And Italian, Iacopo Baussano, Patrick Brzoska, Ugo Fedeli, Claudia Larouche, Oliver Razum, Isaac Chun-Hai Fung
Isaac Chun-Hai Fung
Epidemiology and public health are usually context-specific. Journals published in different languages and countries play a role both as sources of data and as channels through which evidence is incorporated into local public health practice. Databases in these languages facilitate access to relevant journals, and professional education in these languages facilitates the growth of native expertise in epidemiology and public health. However, as English has become the lingua franca of scientific communication in the era of globalisation, many journals published in non-English languages face the difficult dilemma of either switching to English and competing internationally, or sticking to the native …
Open Access For The Non-English-Speaking World: Overcoming The Language Barrier, Isaac Chun-Hai Fung
Open Access For The Non-English-Speaking World: Overcoming The Language Barrier, Isaac Chun-Hai Fung
Isaac Chun-Hai Fung
This editorial highlights the problem of language barrier in scientific communication in spite of the recent success of Open Access Movement. Four options for English-language journals to overcome the language barrier are suggested: 1) abstracts in alternative languages provided by authors, 2) Wiki open translation, 3) international board of translator-editors, and 4) alternative language version of the journal. The Emerging Themes in Epidemiology announces that with immediate effect, it will accept translations of abstracts or full texts by authors as Additional files.

Background: Ahmedabad is an industrial city in Gujarat, India. In 2003, the HIV prevalence among commercial sex workers (CSWs) in Ahmedabad reached 13.0%. In response, the Jyoti Sangh HIV prevention programme for CSWs was initiated, which involves outreach, peer education, condom distribution, and free STD clinics. Two surveys were performed among CSWs in 1999 and 2003. This study estimates the cost-effectiveness of the Jyoti Sangh HIV prevention programme.
Methods: A dynamic mathematical model was used with survey and intervention-specific data from Ahmedabad to estimate the HIV impact of the Jyoti Sangh project for the 51 months between the two CSW …
