AbstractAcute haemorrhagic conjunctivitis (AHC) outbreaks are reported frequently in China. However, the transmissibility of AHC remains unclear. This study aimed to calculate the transmissibility of the disease with and without interventions. An AHC outbreak dataset from January 2007 to December 2016 in different schools was built in Hunan Province. A Susceptible-Infectious-Recovered (SIR) model was adopted to calculate the effective reproduction number (Reff) of AHC. Reff was divided into two parts (Runc and Rcon) where Runc and Rcon represent the uncontrolled and controlled Reff , respectively. Based on Runc and Rcon, an index of effectiveness of countermeasures (Ieff) was developed to assess the effectiveness of countermeasures in each outbreak. During the study period, 34 AHC outbreaks were reported in 20 counties of 9 cities in Hunan Province, with a mean total attack rate of 7.04% (95% CI: 4.97–9.11%). The mean Runc of AHC outbreaks was 8.28 (95% CI: 6.46–10.11). No significance of Runc was observed between rural and urban areas (t = −1.296, P = 0.205), among college, secondary, and primary schools (F = 0.890, P = 0.459), different levels of school population (F = 0.738, P = 0.538), and different number of index cases (F = 1.749, P = 0.180). The most commonly implemented countermeasures were case isolation, treatment, and health education, followed by environment disinfection, symptom surveillance, and school closure. Social distance, prophylaxis, and stopping eye exercises temporary were implemented occasionally. The mean value of Rcon was 0.16 (range: 0.00–1.50). The mean value of Ieff was 97.16% (range: 71.44–100.00%). The transmissibility of AHC is high in small-scale outbreaks in China. Case isolation, treatment, and health education are the common countermeasures for controlling the disease.

Background: The impact of immunization is not uniform in different social groups till today despite of EPI since long. Current study was held to assess the level of knowledge and actual practice of immunization by mothers of under ve children in a rural and urban belt of Udaipur district. A cross sect Methods: ional study was conducted in blocks Binder, Badgav, Ladiya , Kotra, Girva and Salumber of Udaipur district. Randomly 400 families (200 urban, 200 rural) were selected. Ample health education should be given to parents residing in rural areas to rai Result and conclusion: se their knowledge regarding immunization. In rural areas anganwadi workers, ASHA etc should play a signicant role in bringing awareness about immunization and their benets. The group based approach, frequent camps would be more rewarding compared to area approach due to poor socio-economic development of marginalized group likes rural area for programmes like immunization of children.

Objectives. To compare the differences of epidemiology analysis in population birth defects (BDs) between the rural and urban areas of Hunan Province in China. Methods. The data of population-based BDs in Liuyang county (rural) and Shifeng district (urban) in Hunan Province for 2014–2018 were analyzed. BD prevalence rates, percentage change, and annual percentage change (APC) by sex and age were calculated to evaluate time trends. Risk factors associated with BDs were assessed using simple and multiple logistic regression analyses. Results. The BD prevalence rate per 10,000 perinatal infants (PIs) was 220.54 (95% CI: 211.26-230.13) in Liuyang and 181.14 (95% CI: 161.18-202.87) in Shifeng. Significant decreasing trends in BD prevalence rates were noted in the female PIs ( APC = − 9.31 , P = 0.044 ) and the total BD prevalence rate in Shifeng ( APC = − 14.14 , P = 0.039 ). Risk factors for BDs were as follows: rural area, male PIs, PIs with gestational age < 37 weeks, PIs with birth weight < 2500   g , and migrant pregnancies. Conclusions. We should focus on rural areas, reduce the prevalence of premature and low birth weight infants, and provide maternal healthcare services for migrant pregnancies for BD prevention from the perspective of population-based BD surveillance.

The study was conducted in a peri-urban village named, Panchpy under Gafargaon upazila of Mymensingh district with stinging catfish (Heteropneustes fossilis ) and carps ponds to produce aquaponics vegetable kolmi (water spinach, Ipomoea aquatica ) towards using waste substances of intensive stinging catfish ponds. Aquaponic plant (water spinach, Ipomoea aquatica ) was grown in floating trays in the selected ponds. The water quality parameters including, temperature, pH, dissolved oxygen, nitrite and ammonia were measured during study period.The level of ammonia was higher in catfish pond compared to carps pond water. Inversely, the dissolved oxygen content of catfish pond water was lower than that of carps pond. In the stinging catfish pond, the mean value (± SE) of plant length, weight, number of branches and leaves were recorded at 27.67 ± 1.76, 62.67 ± 2.03, 13.00 ± 1.15 and 55.33 ± 3.18, respectively. The corresponding values 19.33 ± 1.45, 46.67 ± 1.86, 9.33 ± 1.45 and 43.00 ± 2.88, respectively in carps pond, were significantly lower than that of catfish pond. Overall the percent weight gain of kolmi was higher in catfish pond. A positive correlation was found between the length and weight of kolmi produced in both catfish and carp ponds, however R2 value of that relationship was higher for catfish pond due to higher level of available waste nutrients in water. This indicates that the potential of aquaponics research and development in intensively feed catfish aquaculture ponds at the farmer level that can feed the growing population in both rural and urban areas of Bangladesh.Res.

<p>Indonesia, being a tropical area with high humidity, is a source of proliferation of worms. Soil-Transmitted Helminths infection is widespread in all rural and urban areas. Children who are infected usually experience lethargy, pallor or anemia, weight loss and listlessness, as well as decreasing their learning concentration and productivity. Prevention effort to reduce the incidence of Soil-Transmitted Helminths infection is conducted by providing the information on Soil-Transmitted Helminths infection. Health promotion cannot be separated from media because messages delivered through media can be more interesting and easier to understand. The purpose of this study is to determine the effectiveness of a pocket book to increase preventive behavior for Soil-Transmitted Helminthes Infections. This type of research was a quasi-experimental study. The samples of this study were all elementary school infected students in grades 3, 4, and 5 with a package of interventions for the provision of a pocket book. The effectiveness of the pocket book is determined by using the t test. There are differences between the mean of knowledge and attitude, but the mean of behavior of Soil -Transmitted Helminths Infection before and after the pocket book is similar.</p>

A questionnaire-based cross-sectional study was carried out to assess the awareness of diabetes mellitus among rural and urban diabetics. After analyzing the awareness level of both populations, the urban diabetics were found to be more educated about diabetes. A 25-question survey was used to judge the awareness level of diabetes mellitus. A total of 240 diabetics were surveyed, 120 each from rural and urban areas. The mean awareness among the rural population was 13 (SD± 2) correct answers out of a possible 25. Similarly, in the case of the urban diabetics the mean awareness was 18 (SD± 2) correct answers. The survey was conducted on randomly chosen diabetics belonging to Lahore and Faisalabad, (urban areas), as well as Habibabad, Haveli Koranga and Baba Kanwal (rural areas). The results emphasize the interrelation between demography and awareness of diabetes mellitus. The rural diabetics are far less knowledgeable about diabetes mellitus, its management and its complications. Thus, there is an urgent need to improve the awareness level of diabetes mellitus in rural areas. Doing so will give rise to a healthier workforce and a lessened economic burden on Pakistan.

Honey and honey trade is an important economic activity for many tropical rural and urban areas worldwide. In West Africa and other part of the world, honey and honey products holds high socio–cultural, religious, medicinal and traditional values. Therefore, to maximize benefits or to enhance profit, a variety of components are added to the raw, fresh and unprocessed honey, introducing the possibility of heavy metals contaminants. Therefore the honey sold in various places, markets and shops  in some states in Northern Nigeria (Benue, Nassarawa and Taraba) including Abuja FCT, in Nigeria was analyzed to determine the level of heavy metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn).All the honey samples contain heavy metals. The results ranged from 0.028–0.070, 0.023–0.058, 0.042–0.092, 4.231–8.589, 8.115–14.892, 0.078–0.922, 0.044–0.092, 0.041–0.087 and 18.234–28.654 μg/L for Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn respectively. The mean concentration (μg/L) of the heavy metals Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn of the regularly marketed honey is significantly higher than the mean concentration observed in raw, fresh and unprocessed honey. However, continued consumption of honey with high heavy metal content might lead to exposure to chronic heavy metal poisoning.

Abstract Background : Groundwater contaminant such as nitrate (NO 3 - ) is one of the environmental factors that can affect human health . Methemoglobinemia of infants, thyroid disorders, and probably some carcinogenic effects, are health concerns associated with dietary nitrate. Isfahan province has a dry and semi-arid desert climate that the main source of various applications in this province is groundwater resources. This study evaluated spatial analysis of the concentration of NO 3 - in groundwater resources and its possible health risk to residents. Results : It was indicated that nitrate concentrations in the rural and urban areas were in the range of 0.4–137 mg/L NO 3 − with the mean of 33.72 mg/L NO 3 − , and 2.9-209 mg/L NO 3 - with the mean of 38.87 mg/L, respectively. As well, 226 samples (25%), and 104 (24%) ones were detected above the Iran and World Health Organization guidelines 50 mg/L as NO 3 − . While the highest levels of NO 3 − which were located in the west and central groundwater resources of the province were in the agricultural and residential areas. The HQ for Infants, in 32% of samples, urban 136 and rural 297 samples were higher than 1 (HQ>1). Also, in urban area HQ was more than 1 in 8, 5, 1, and 3 samples in children, teens, male and female, respectively. Conclusions : Infants were the most vulnerable compared with the other groups. Therefore, in some areas, there are potential risks of methemoglobinemia, especially for infants. So, it is critical to adopt specific strategies to reduce the nitrate concentration in the studied groundwater.
