South Asia emerges as one of the most susceptible regions to a plethora of direct and indirect repercussions stemming from climate change. These include, but are not limited to, the rising sea levels, heightened cyclonic activity, and shifts in ambient temperature or precipitation patterns. Despite an abundance of publications delving into the associated impacts, our objective is to synthesize pertinent literature with the aim of discerning commonalities in research findings, assessing the most affected areas in terms of health, and delving into potential avenues for mitigating the associated impacts.
Notwithstanding its relatively minor contribution to greenhouse gas emissions, South Asia finds itself exceptionally vulnerable to the perils of climate change due to a confluence of factors, including its geographical and topographical positioning, burgeoning population density, rapid urbanization, deficient health infrastructure, and an economy predominantly reliant on agriculture. This region stands at the forefront of vulnerability to various direct and indirect consequences of climate change, such as sea level rise, extreme weather events encompassing cyclones and droughts, as well as alterations in ambient temperature and precipitation patterns.
Our comprehensive review is centered on an in-depth, country-wise exploration of the available literature pertaining to four South Asian nations: India, Bangladesh, Nepal, and Sri Lanka. Through this analysis, we seek to evaluate the impacts of climate change from both direct and indirect perspectives. A discernible trend emerges, indicating that extreme weather events exert a palpable impact on health and healthcare systems in areas deemed 'climate-sensitive.' However, noteworthy gaps persist in the existing literature, warranting further investigation to substantiate the link between climate events and their health impacts. This void also presents an opportune moment to contextualize strategies for mitigation and adaptation, crafting more sustainable approaches that contribute to the well-being of both the populace and the planet
For the past 18 years, northern Sri Lanka has been affected by armed ethnic conflict. This has had a heavy impact on displacement of civilians, health delivery services, number of health professionals in the area and infrastructure. The north of Sri Lanka has a severe malaria burden, with less than 5% of the national population suffering 34% of reported cases. Health care providers investigated treatment-seeking behaviour and levels of treatment failure believed to be the result of lack of adherence to treatment.
METHODS
Pre- and post-treatment interviews with patients seeking treatment in the outpatient department (OPD) and focus groups.
RESULTS
A total of 271 persons completed interviews: 54.4% sought treatment within 2 days of the onset of symptoms, and 91.9% self-treated with drugs with prior to seeking treatment, mainly with paracetamol. Self-treatment was associated with delaying treatment (RR 3.55, CI 1.23-10.24, P=0.002). In post-treatment interviews, self-reported default was 26.1%. The main reasons for not taking the entire regimen were side-effects (57.6%) and disappearance of symptoms (16.7%). Focus groups indicated some lack of confidence in chloroquine treatment and prophylaxis, and scant enthusiasm for prevention methods.
CONCLUSIONS
A number of factors contribute to a lack of access and a lower quality of care for malaria: lack of medical staff and facilities because of the fighting; lack of confidence in treatment, and perception of malaria as a routine illness. Prevention efforts need to take into account certain beliefs and practices to be successful.
District Chest Clinic, Kalutara, Sri Lanka.
OBJECTIVES
To determine the coverage of culture and drug susceptibility testing (CDST), delays in CDST, treatment initiation, obtaining CDST results and treatment outcomes of previously treated tuberculosis (TB) patients.
DESIGN
Retrospective cohort study involving review of records and reports. All previously treated TB patients from January 2008 to June 2013 were included in the study.
RESULTS
Of 160 patients, 126 (79%) samples were sent for CDST; 79 (63%) were culture-positive and no multi-drug-resistant (MDR) TB cases were reported. Respectively 9% and 15% of patients experienced a delay in sending samples (median delay 21 days) and receiving CDST reports (median delay 71 days), while 20% experienced delays in initiating the retreatment regimen (median delay 11.5 days). The cohort recorded an 82% treatment success rate.
CONCLUSION
Of all retreatment patients, only 79% were tested for CDST and there were sizeable delays in sample transportation and treatment initiation. Possible ways forward to strengthen the programme are discussed.
The purpose of this study was to describe the injuries sustained by displaced people returning home after a military conflict when landmines were not removed.
METHOD
This study describes the landmine injuries to patients at the Jaffna Teaching Hospital in northern Sri Lanka over a 20-month period, from May 1, 1996, to December 31, 1997.
RESULTS
There were definite and identifiable landmine injury patterns. Patients were most often wounded in the lower extremities, had multiple wounds, and were injured together in groups. Victims were most often male, but there were unusually high numbers of women, children, and elderly injured. Mortality rates and amputation rates were high. Deaths occurred early after injury. Higher incidences of mine injuries could be associated with two important activities: returning home and agriculture.
CONCLUSIONS
Civilians returning home after armed conflicts are at risk of injury when landmines are not removed. No one is spared. This problem is preventable.
