In addition to identifying potential access to safe drinking water during climate change and potential health hurdles brought on by water-related diseases, it is important to learn how to reduce the spread of water-borne diseases. Methods: A mixed method design was adopted to evaluate this research, and probability sampling, more specifically simple random sampling, was used to select to sample from the target population. The study was conducted in Taltali upazila of the Barguna district, and data was collected from 384 respondents;among them, 5 respondents were selected for the key informant interview. The research project began in June 2022 and was completed in December 2022. Results: 41.4% of respondents said they suffer from dysentery, 22.4% said the expense of treating water-borne diseases has increased as a result of climate change, and 37.8% said they must travel great distances to obtain clean drinking water. Currently, 41.7% of individuals utilize tube-well water, compared to 19.3% five to ten years ago, and 27.4% have been taught that water filtration helps reduce the spread of water-borne diseases. Conclusions: People’s vulnerability to climate change in the study area is a result of factors such as rapid population increase, unequal access to resources, food insecurity, a long distance to collect water, inadequate medical facilities, a lack of poverty, and a weak health system.展开更多

Fatal outbreaks of cholera struck several provinces of the country, including Baghdad. The United Nations Environment Programme (UNEP) also says air pollution, resulting from burning oil and aggravated by war, is cause for concern. The study area Baghdad has been divided into two parts: Central Baghdad and Outskirts of Baghdad (included in Baghdad but near the boundaries of Baghdad). The outskirts of Baghdad comprises of 4 cities: Al-Hussaniya located in northern part of Baghdad, Abu-Gurabe located in the western side of Baghdad, Jissr Diyala located in the eastern side of Baghdad and finally Al-Mahmodiya located in the southern side of Baghdad. These cities are in very poor situation in terms of water supply. The quality of water supplied is bad as no attention is given to WTP's in these places, which is also because of the fact that given the insecure war conditions, these areas are inaccessible. The sewage is thrown directly into the river because these areas do not have sewage treatment plants. In case of central Baghdad the water supply and sewerage network are broken in some places. Due to this there is mixing of water between the two networks. For this study we taking water supply samples and collect all the samples from WTPs and water supply network (houses, shops and different places). We made the analysis to parts first bacteriologies, second chlorine and after analysis these samples in lab we will give in our study numbers of fail samples, type of diseases and how many case during year 2007 in Baghdad City. Also in this study we will give Estimated Deaths from Water-Related Diseases 2010 to 2035.展开更多

Inhabitants of this locality consume water from these sources without any prior treatment which can lead to health problems if the water sources are contaminated. Six water sources were sampled in November 2017, January, April and July 2018 and examined for organoleptic, physico-chemical and bacteriological parameters using standard methods. Results of organoleptic and physical parameters showed that most of the sources were within the WHO acceptable limits with pH varying from moderately acidic to weakly basic. Chemical properties revealed that all the analysed ions were found within the WHO guidelines and the water sources ranged from soft (hardness +, K+, Ca2+, Mg2+, NO3-? and NH4+??(p Escherichia coli, Enterobacter, Streptococcus, Salmonella and Shigella spp, were identified in all the sampled waters, suggesting recent contamination of the sources by human or animal faeces. The sources were unfit for domestic uses and thus, exposed the local population to water borne diseases such as typhoid, diarrhoea and dysentery. Hence, home treatment methods such as chlorination, filtration, boiling and solar disinfection should be implemented prior to consumption.展开更多

The project aimed at screening sachet water for mi-croorganisms related to water-borne diseases. One hundred sachet water samples were randomly collected. The pH was determined using a digital pH meter. Values ranged between 6.3 - 8.7, with 28% of the samples being above the WHO approved range of 6.4 - 7.6. No residual chlorine was detected. Gram negative isolates were 80%, while 20% were Gram positive. Faecal coliforms above the recommended WHO zero coliforms per 100 mL were 30%. Escherichia coli had the highest incidence (17%), followed by Acinetobacter sp. (12%), Enterobacter aerogenes (11%), Flavobacterium sp. (11%), Proteus mirabilis (11%), Staphyloccocus aureus (10%), Bacillus subtilis (8%), Micrococcus sp. (5%), Streptococcus faecalis (2%), Klebsiella sp. (2%) and Vibrio cholerae (1%). There is urgent need for public awareness campaigns against water-borne diseases.展开更多

This study was set up to investigate the geographical distribution of Bovine that was affected by Leptospira hardijo, in River Nile state, on October 2012. Locations of targeted cattle were delimited using GPS. Fifty three (53) of blood samples were collected, and screened in the laboratory for Leptospira hardijo specific antibodies using indirect ELISA. 15.09% had evidence of infection as determined by the presence of anti-leptospira antibodies. It was inferred that no incidences were recorded in 45 locations out of the 53 selected locations in the state. Leptospirosis risk area for transmission was mapped using 5 km buffer distance. Animals’ movements routes were mapped with their contacts area and positive samples locations, hafair locations where animals contacts were mapped. This study demonstrated the value of GIS and GPS in disease mapping for animals’ health, and this might help veterinary authorities to implement strategic interventions for animal disease control.展开更多
