Abstract: Travel medicine has emerged as a new field of medicine that involves pre-travel evaluation, contingency planning during travel, and post-travel care. Its implementation showed major discrepancies among different countries. This study aims to assess the health information given to travelers and detect their sources of information. This is a cross sectional analytical observational study of 397 travelers implemented on different travel destinations all over Egypt. It adopts self-administered structured questionnaires according to the International Travel Health Questionnaire (ITHQ) and in-depth interviews with managers in the Ministry of Tourism. The results showed that 17.5% of the international travelers and none of the national travelers heard about the ITHQ; whereas, 58.9% of the international travelers and 26.8% of the national travelers took information about safety measures from different sources. However, there was a lack of travelers’ knowledge about safety measures with no obvious role of travel agencies.[...] Read More.

Abstract: Malaria is under regular and ongoing surveillance, to detect changes in its trends or distribution in order to initiate investigative or control measures in the country. Owing to limited availability of resources and rational use under the program, prevention and control activities against malaria varies in areas with different intensity of malaria transmission. Transmission dynamics, surveillance, mapping of disease burden for malaria in arid ecological setting of Jodhpur, Rajasthan has described in this study. Monthly epidemiological reports of Jodhpur City, district Jodhpur and all its community health centres were obtained from the office, Chief Medical and Health Officer district Jodhpur for the period 2002 to 2006. Secular trend of malaria incidence, transmission dynamics, mapping of disease burden areas and surveillance of malaria was described.

Abstract: Although HIV transmission among Namibian in-school adolescents is mainly heterosexual, previous data on sexual activity are not disaggregated, making it difficult to target interventions. This study conducted a disaggregated analysis of coital activity and explored various factors associated with coital activity among Namibian High School students. A cross-sectional survey was carried out in 18 schools located in six education regions. Data were collected from 829 students through a structured questionnaire. Pearson χ2 analysis was used to determine the distribution of coital activity for students from different regions, rural-urban areas, ethnic groups, and gender. Factors associated with coital activity were established by the use of odds ratios and multivariate logistic regression analysis. Overall, 50.2% of the students never had sex before and 29.2% were sexually active. Pearson χ2 analysis showed that coital activity was significantly high among students in the Caprivi region, urban areas, Lozi, Herero and Damara-Nama ethnic groups, and male gender. Multivariate logistic regression showed that the only significant factors positively associated with coital activity were Herero ethnicity, male gender, testing for HIV, thinking one could not get HIV if they were faithful to a single sexual partner, having a boyfriend of girlfriend, and drinking beer. These disaggregated results will help design targeted HIV/AIDS preventive programmes for High School students in Namibia. This can be done by targeting messages that reduce students’ coital activity by way of altering personal, peer, and social behaviours.[...] Read More.

Abstract: Northwest Nigeria is frequently beset with inadequate water supply. The safety of drinking water to the people in this part of the country has been of major concern as a result of frequently reported incidences of waterborne infections. To ascertain incidences of waterborne infections in this study, patient medical records in several primary health care centres in Sokoto, Shuni and Tambuwal towns in Northwest Nigeria were examined to collect data on incidences of waterborne infections and bio-data of the patients. Simple statistical analysis (Percentage) of collated data was carried out. The records showed that there are high incidences of waterborne infections namely typhoid, cholera, dysentery, diarrhoea and gastroenteritis in the three towns, and that these are more frequent in children below the age of 5 years. Gender distribution of diarrhoea and dysentery cases in 2004 and 2005 showed on average that more female than male residents contracted the infections. The number of cases of waterborne infections in the three towns increased from 10.03% in 2004 to 14.14% in 2005. Diarrhoea, constituting 6.23% in 2004 and 10.04% in 2005 was the most commonly reported cases of waterborne infection in the three towns. Shuni recorded the highest (8.95%) incidences of diarrhoea infection in 2004, followed by Tambuwal (6.23%) and Sokoto had the least (4.81%) while in 2005 Sokoto had the highest (11.99%) followed by Tambuwal (10.23%) and Shuni had the least (7.55%). Pre-study investigations have shown that people in this part of the country lack wholesome drinking water, government should therefore endeavour to make potable water abundant and accessible to its people.[...] Read More.

Abstract: This study was carried out to determine the prevalence of multiple antibiotic-resistant faecal indicator bacteria in streams and wells which serve as major sources of water for inhabitants of Ile-Ife city in Southwestern Nigeria. Water samples from 2 streams and 10 wells situated at different parts of the city were collected over a 6-month period. The total heterotrophic bacteria, faecal coliform and enterococci counts were performed using standard procedures, and the sensitivity of the isolates to antibiotics was tested. The study indicated high faecal indicator concentrations exceeding quality standards for drinking and recreational waters according to World Health Organization (WHO) and United States Environmental Protection Agency (USEPA). All the faecal coliforms and enterococci isolates presented multiple antibiotic resistances. The water sources pose a threat to human health due to the danger of waterborne diseases and potential for the transfer of antibiotic resistance genes to pathogens. Effective public health education aimed at creating awareness of the implications of consumption of contaminated and untreated water is imperative. Antibiotics should only be administered based on physicians’ prescription.[...] Read More.

Abstract: Under-nutrition prevents growth and development in children and is the leading factor to illness and death among children less than five years of age in developing countries. The objective of the study was to determine associations of demographic, cultural and environmental factors with frequency and severity of malnutrition among children less than five years of age in Zambia. We used data from the Zambia multiple indicator cluster survey (MICS) from years of 1999 to 2000. Altogether 6,142 children participated in the survey. The prevalence rates for being "underweight", "stunted" and "wasted" were 17.6, 37.5 and 4.1%, respectively. Compared to children from Western province, those from Luapula, Northern, and North-West provinces were more likely to be underweight. Children from Lusaka, Southern, Copperbelt, Eastern, and Central provinces were less likely to be underweight compared to those from Western province. Other factors associated with children malnutrition included sex, low educational level of householder and mother, poverty, vaccination status and type of toilet. The data acquired in this study may be used in developing interventions to prevent and mitigate children malnutrition. Special attention may have to be given to the provinces where children are more likely to suffer from malnutrition.[...] Read More.

Abstract: Partially eutrophicated site (A) and free-flowing site (B) of Otamiri River in Owerri, Nigeria, separated by a barricade were evaluated to determine their relative pollution status. Microbiological analysis using membrance-filtration techniques detected high presence of Salmonella spp., Vibro spp., Staphylococus aureus and faecal Streptococci. Aerobic bacterial counts of 5.0 x 105 cfu/100ml were obtained from site B and 4.5x 103 cfu/100ml from site A. The physico-chemical analysis revealed high conductivity of 178 umhoo/cm with total dissolved solids (TDS) of 89.0 mg/L at site B and 52 umhoo/cm with TDS of 26mg/L at site A. Recovery of PO43-, SO42-, N03-, was obtained, though more at site A than Site B, indicating pollution. Statistical analysis revealed significant differences (P[...] Read More.

Abstract: Iodine deficiency disorders (IDD) are major public health problems in India, including Gujarat. Narmada district is a tribal area. The present study was conducted to estimate the prevalence of goitre in primary school children; to determine median urinary iodine concentration; to assess level of iodine in salt samples at household and retail shop level; and to study profile of salt sold at retail shops in Narmada district, Gujarat. 30 cluster survey method was used for the study in primary schools of Narmada District. Children studying in 1st to 7th standard were used in this study. A total of 70 students including five boys and five girls from 1st to 7th standard present in class on the day of visit were selected randomly for Goitre examination, so, total 2100 students were examined in schools. Urine sample was collected from one boy & one girl from each standard in each cluster. From community, at least 28 students including two boys and two girls from each standard in same age group were examined and also salt samples were tested from their households. So, total 2100 students were examined in schools and 858 students were examined out of schools in the selected villages. From each village, one retail shop was visited and salts were purchased and tested for iodine on the spot with spot kit. Goitre prevalence was found 18.1% among primary school children including grade 1 - 12.4% and grade 2 - 5.7%. As the age increases the Goitre prevalence also increases except in the age group of 9 years. Median urinary iodine excretion level was found 110 µg/L. Iodine level >15 ppm was found in 93.7% salt samples tested at household level. Present study showed mild Goitre prevalence in primary school children in Narmada District of Gujarat and iodine content of salt found adequate at household level.[...] Read More.

Abstract: Alcohol use is an important preventable risk factor for several non-communicable diseases (NCDs) and injuries that is related to lifestyle choices. The objective of the study was to determine the prevalence of alcohol consumption and its correlates. A cross sectional study utilizing a WHO stepwise approach to surveillance of NCDs was conducted in Lusaka district, Zambia. Current alcohol consumption was defined as having consumed alcohol in the previous 30 days to the survey. Complex samples logistic regression was used to determine independent predictors. A total of 1928 individuals participated in the survey. A third of the participants were males and 53.2% were in the age group 25 to 34 years. Overall, 35.8% of the respondents had attained secondary level of education. The prevalence for current consumption of alcohol was 20.7% (37.9% of males and 12.2% of females). Sex was associated with alcohol consumption, with females being 68% (AOR = 0.32, 95%CI [0.20, 0.51]) less likely to consume alcohol compared to male respondents. Age, education, body mass index and sedentary were not independently associated with alcohol consumption. The high prevalence of alcohol use among Zambian adults indicates an urgent need for specific measures such as public awareness campaigns, policies, and regulations.[...] Read More.
