Survival rate of HIV-infected patients on treatment are poorly understood in Ethiopia. The study aimed to determine the probability of survival and predictors of mortality, among HIV-infected adults on antiretroviral therapy in Jinka Hospital, South Omo, Ethiopia.

The distinct characteristic of Korean MERS outbreak is that it not only shows intra-hospital transmission, but it also shows hospital-to-hospital transmission. It is the largest MERS outbreak outside the Middle East: 186 confirmed cases and 36 fatal cases. All confirmed cases suspected of hospital acquired infection except one case of household transmission and two cases of under examination. The Korean health care system became the major factor for the outbreak. Taking this as an opportunity, Korea should carefully assess the base problems of the vulnerability in the hospital infection and make short- as well as long-term plans for countermeasures. In addition, it is hoped that this journal, Epidemiology and Health becomes a place of discussion where various topics regarding MERS are being discussed and shared.

This study aims to investigate health disparities between lesbian, gay, and bisexual (LGB) adults and the general population in South Korea, where there is low public acceptance of sexual minorities and a dearth of research on the health of sexual minorities.

Concepts: LGBT, Sexual orientation, Homosexuality


Aedes mosquito is responsible for transmitting dengue virus. Mosquito lifecycle is known to be influenced by temperature, rainfall and relative humidity. This retrospective study was planned to investigate if climatic factors can be used to predict occurrence of dengue cases in our area.

Concepts: Scientific method, Mosquito, Precipitation, Humidity, Water vapor, Aedes aegypti, Aedes, Dengue fever


The 2017 guideline for the prevention of travelers' diarrhea (TD) by International Society of Travel Medicine (ISTM) suggested that ‘there is insufficient evidence to recommend the use of commercially available prebiotics or probiotics to prevent or treat TD’. But, a meta-analysis published in 2007 reported significant efficacy of probiotics on TD [summary RR (sRR) =0.85, 95% confidence interval (CI): 0.79-0.91). The aim was to synthesize efficacy of probiotics on TD by updating the meta-analysis of double-blind, placebo-controlled, randomized human trials.


Tobacco is a major causative agent for various deadly diseases such as coronary artery disease and cancers. It is the largest avoidable health risk in the world, causing more problems than alcohol, drugs, high blood pressure, excess weight or high cholesterol. As countries, like Indonesia, prepare to develop national policy guidelines for the tobacco reduction, the scientific community can help by providing a continues ideas and forum for sharing and distributing information, writing up guidelines, reviewing best practices, raising funds and establishing partnerships. We propose several strategies such as advertisement interference, cigarette pricing policy, adolescent smoking prevention policy, support for smoking cessation therapy, special informed consent for smokers, smoking prohibition at public spaces, career incentives, economy incentives as well as advertisement incentives in reducing tobacco consumption. We hope that these strategies would help people give up their smoke habit, or help them from starting to smoke.

Radon is a naturally occurring radioactive material formed when uranium and thorium found in the earth’s crust or construction materials slowly decay. Internal exposure to radon accounts for about half of the natural background radiation dose of which humans are exposed to annually. Radon is a carcinogen and is the second leading cause of lung cancer following smoking. The association between radon and lung cancer has been consistently reported in epidemiological studies on mineworkers and the general population with indoor radon exposure. However, radon’s association with other diseases, such as leukemia and thyroid cancer, has not been clearly established. Radiation dose is assessed by applying different dose conversion coefficients according to the source (e.g., radon or thoron) and form of exposure (e.g., internal or external). However, if the estimated dose is identical, its effects on human health are also identical regardless of the source or form of exposure (assuming that individuals have the same sensitivity to radiation). Recently, radiation exceeding the annual dose limit of the general population (1 mSv/year) was detected in bed mattresses produced by D company due to the use of monazite-based anion powder containing uranium/thorium. This has sparked concerns about health hazards caused by radiation exposure on mattress users. In this regard, this study presents scientific information about the assessment of radon and thoron exposure and its human implications for human health, which is a recent topic of interest and debate in society.


Elderly people often are abused in many ways with serious and pasting consequences. Elder abuse remains one of the most hidden forms of family conflict and it is anticipated that it is rising in many countries which are rapidly experiencing population aging. The purpose of study is to investigate the status of domestic elder abuse in elderly women and their related factors in Tehran.


Although the nationwide inoculation rate of varicella vaccine was about 95% in Korean children, the notified numbers of varicella cases are increasing till now, unexpectedly. To suggest some hypotheses about the gap, an age-period-cohort (APC) analysis as descriptive epidemiology study was conducted for children resident in Jeju-do, Republic of Korea (ROK).


Little is known on the life expectancy of HIV positive patients in Iran. This study aimed to estimate the life expectancy of HIV positive patients in Iran.
