Cyclospora cayetanensis is emerging as an important cause of food-borne diarrheal outbreaks, especially in developed regions like the United States and Europe. We describe an outbreak of cyclosporiasis in Peruvian naval recruits that we believe to be the first among a local population in a developing region.
Protozoal diseases are increasingly recognized as the cause of diarrhoeal outbreaks in both developed and developing countries. Cyclospora cayetanensis has been responsible for several epidemics in the last decade. In March 2005, an outbreak of diarrhoea was identified in recruits at the Ancon Naval Base in Lima, Peru. A case-control study was carried out. The overall diarrhoea attack rate was 53% (45/85). Complete data from 52 recruits were available for the analysis; 37 met the criteria for case and 15 for control. The epidemic curve indicated a point source transmission, with cases occurring over 9 days with a peak on the fifth day. Cyclospora cayetanensis was found in 7/37(18.9%) cases and 1/15 (6.7%) controls via standard microscopic techniques. PCR for C. cayetanensis detected 20/35 (57.1%) cases and 3/15 (20%) controls, demonstrating the improved diagnostic yield of this technique. This is the second report to characterize an outbreak of diarrhoea due to C. cayetanensis in Peru among a local population. The epidemiology and clinical course were similar to other reported outbreaks in developed regions. PCR greatly increased the number of C. cayetanensis cases detected during this outbreak, allowing the correct identification of its aetiology.
Sustainable Development Goal 6 (SDG-6) addresses poor water quality, inadequate sanitation, and improper hygiene, all of which negatively impact health and disproportionately impact Indigenous Peoples’ health. Understanding and responding to local contexts is critical to effectively improve water, sanitation, and hygiene (WASH); however, in-depth understanding of local knowledge, practices, and perceptions are often overlooked. As such, this study described the knowledge, practices, and perceptions of WASH held by residents of two Indigenous Shawi communities in the Peruvian Amazon. Quantitative data were collected via a cross-sectional survey and analyzed using descriptive statistics. Qualitative data were collected via interviews, PhotoVoice, focus group discussions, and participatory transect walks, and analyzed using a constant comparative approach to thematic analysis. Emergent themes included characterizing water sources, collection methods, and consumption patterns; knowledge, perceptions, and practices related to WASH; and knowledge and perceptions of health issues related to WASH. This study provides insight into the ongoing challenges related to WASH in Indigenous communities in the Peruvian Amazon and highlights the need to prioritize interventions that will advance WASH-related SDGs.
Climate change impacts on water systems have consequences for Indigenous communities. We documented climatic changes on water systems observed by Indigenous Shawi and resultant impacts on health and livelihoods, and explored adaptation options and challenges in partnership with two Indigenous Shawi communities in the Peruvian Amazon. Qualitative data were collected via PhotoVoice, interviews, focus group discussions, and transect walks, and analyzed using a constant comparative method and thematic analysis. Quantitative data were collected via a household survey and analyzed descriptively. Households observed seasonal weather changes over time (n = 50; 78%), which had already impacted their family and community (n = 43; 86%), such as more intense rainfall resulting in flooding (n = 29; 58%). Interviewees also described deforestation impacts on the nearby river, which were exacerbated by climate-related changes, including increased water temperatures (warmer weather, exacerbated by fewer trees for shading) and increased erosion and turbidity (increased rainfall, exacerbated by riverbank instability due to deforestation). No households reported community-level response plans for extreme weather events, and most did not expect government assistance when such events occurred. This study documents how Indigenous peoples are experiencing climatic impacts on water systems, and highlights how non-climatic drivers, such as deforestation, exacerbate climate change impacts on water systems and community livelihoods in the Peruvian Amazon.
