[Association between socioeconomic, health, and primary care conditions and hospital morbidity due to waterborne diseases in Brazil]. / Associação entre condições socioeconômicas, sanitárias e de atenção básica e a morbidade hospitalar por doenças de veiculação hídrica no Brasil.

The current study aimed to assess the association between socioeconomic conditions, basic sanitation, and coverage by family health teams and hospitalizations for waterborne diseases. The analysis of socioeconomic conditions and sanitation was based on an ecological study with data from the Brazilian National Household Sample Survey (PNAD) and the Brazilian Health Informatics Departament (DATASUS) database (observations for the States and Federal District) for the year 2013. Associations between family health teams and hospitalization were assessed by simple regressions, with data from DATASUS and the Department of Primary Care of Ministry of Health from 1998 to 2014. Connection to the public sewage system, low schooling, and family health team coverage were significantly associated (p < 0.05) with hospitalizations for waterborne diseases. Based on attributable risk analysis, for Brazil as a whole in 2013, 57,574 (16.3%) of hospital admissions for waterborne diseases could have been avoided by adequate sewage disposal, which would also have avoided BRL 20,372,559.90 in treatment costs and 172,722 days lost to hospitalization. The results emphasize the importance of integrated sanitation policies, education, and health care that consider regional inequalities, thereby contributing to improvement of the population's health conditions.

O presente estudo teve como objetivo avaliar a associação entre condições socioeconômicas, de saneamento básico e de cobertura por equipes de saúde da família (EqSF) sobre as internações por doenças de veiculação hídrica no Brasil. A análise das condições socioeconômicas e de saneamento se deu por meio de um estudo ecológico com dados da Pesquisa Nacional por Amostra de Domicílios (PNAD) e do Departamento de Informática do SUS (DATASUS) - observações dos Estados e Distrito Federal - para o ano de 2013. A relação das EqSF com as internações foi avaliada por meio da estimação de regressão simples, com dados coletados no DATASUS e Departamento de Atenção Básica do Ministério da Saúde, para o período de 1998 a 2014. A existência de coleta de esgoto por rede geral, a baixa escolaridade e a cobertura por EqSF influenciaram, com significância estatística (p < 0,05), as internações avaliadas. Pela análise do risco atribuível, estimou-se que no Brasil, tomando-se como base os dados de 2013, 57.574 (16,3%) das internações por doenças selecionadas poderiam ter sido evitadas, caso as condições de esgotamento sanitário fossem adequadas. Seriam ainda evitados os gastos com o tratamento delas, calculado em R$ 20.372.559,90 e os dias perdidos com as internações, 172.722. Sugere-se que a adoção integrada de políticas de saneamento, educação e assistência à saúde que considerem as desigualdades regionais contribuirá para a melhoria das condições de saúde da população.

Se evitarían incluso los gastos con su tratamiento, calculado en BRL 20.372.559,90, y los días perdidos con los internamientos en 172.722.

Estimate of incidence and cost of recreational waterborne illness on United States surface waters.

BACKGROUND: Activities such as swimming, paddling, motor-boating, and fishing are relatively common on US surface waters. Water recreators have a higher rate of acute gastrointestinal illness, along with other illnesses including respiratory, ear, eye, and skin symptoms, compared to non-water recreators. The quantity and costs of such illnesses are unknown on a national scale. METHODS: Recreational waterborne illness incidence and severity were estimated using data from prospective cohort studies of water recreation, reports of recreational waterborne disease outbreaks, and national water recreation statistics. Costs associated with medication use, healthcare provider visits, emergency department (ED) visits, hospitalizations, lost productivity, long-term sequelae, and mortality were aggregated. RESULTS: An estimated 4 billion surface water recreation events occur annually, resulting in an estimated 90 million illnesses nationwide and costs of $2.2- $3.7 billion annually (central 90% of values). Illnesses of moderate severity (visit to a health care provider or ED) were responsible for over 65% of the economic burden (central 90% of values: $1.4- $2.4 billion); severe illnesses (result in hospitalization or death) were responsible for approximately 8% of the total economic burden (central 90% of values: $108- $614 million). CONCLUSION: Recreational waterborne illnesses are associated with a substantial economic burden. These findings may be useful in cost-benefit analysis for water quality improvement and other risk reduction initiatives.

Estimates of the burden of illness for eight enteric pathogens associated with animal contact in Canada.

Enteric pathogens are commonly known to be transmitted through food or water; however, contact with animals is another important transmission route. This study estimated the annual burden of illness attributable to animal contact for eight enteric pathogens in Canada. Using data from a Canadian expert elicitation on transmission routes, the proportion of enteric illnesses attributable to animal contact was estimated for each pathogen to estimate the annual number of illnesses, hospitalizations and deaths in Canada. For each estimate, a mean and probability intervals were generated. Of all illnesses caused by these eight pathogens, 16% were estimated attributable to animal contact. This estimate translates to 86 000 (31 000-166 000) illnesses, 488 (186-890) hospitalizations and 12 (2-28) deaths annually for the eight pathogens combined. Campylobacter spp. is the leading cause of illnesses annually, with an estimated 38 000 (14 000-71 000) illnesses occurring each year, followed by non-typhoidal Salmonella spp. (17 000, 6000-32 000). The majority of hospitalizations were attributable to non-typhoidal Salmonella spp. (36%) and Campylobacter spp. (31%). Non-typhoidal Salmonella spp. (28%) and Listeria monocytogenes (31%) were responsible for the majority of the estimated deaths. These results identify farm animal and pet/pet food exposure as key pathways of transmission for several pathogens. The estimated burden of illness associated with animal contact is substantial.

Prevalence and direct costs of emergency department visits and hospitalizations for selected diseases that can be transmitted by water, United States.

National emergency department (ED) visit prevalence and costs for selected diseases that can be transmitted by water were estimated using large healthcare databases (acute otitis externa, campylobacteriosis, cryptosporidiosis, Escherichia coli infection, free-living ameba infection, giardiasis, hepatitis A virus (HAV) infection, Legionnaires' disease, nontuberculous mycobacterial (NTM) infection, Pseudomonas-related pneumonia or septicemia, salmonellosis, shigellosis, and vibriosis or cholera). An estimated 477,000 annual ED visits (95% CI: 459,000-494,000) were documented, with 21% (n = 101,000, 95% CI: 97,000-105,000) resulting in immediate hospital admission. The remaining 376,000 annual treat-and-release ED visits (95% CI: 361,000-390,000) resulted in $194 million in annual direct costs. Most treat-and-release ED visits (97%) and costs ($178 million/year) were associated with acute otitis externa. HAV ($5.5 million), NTM ($2.3 million), and salmonellosis ($2.2 million) were associated with next highest total costs. Cryptosporidiosis ($2,035), campylobacteriosis ($1,783), and NTM ($1,709) had the highest mean costs per treat-and-release ED visit. Overall, the annual hospitalization and treat-and-release ED visit costs associated with the selected diseases totaled $3.8 billion. As most of these diseases are not solely transmitted by water, an attribution process is needed as a next step to determine the proportion of these visits and costs attributable to waterborne transmission.
