“…Salazar-Lindo et al (17) reported a marked increase in the number of cases of diarrhea and dehydration in infants and young children in Lima, Peru, during an El Niño event, and Checkley et al (18) described the effects of El Niño and ambient temperature on children admitted to the hospital with diarrheal diseases. A 2-fold increase in hospital admissions was evident during the winter of 1997-1998, suggesting that El Niño had an effect on hospital admissions for diarrhea which was far greater than that explained by seasonal temperature changes.…”

“…Diarrhoea morbidity is influenced by weather and climate variability (Victora et al 1985, Salazar-Lindo et al 1997, Checkley et al 2000. Temperature affects pathogen survival (Kovats & Tirado 2006), and watersupply contamination due to heavy rainfall has led to diarrhoea outbreaks (Curriero et al 2001, Auld et al 2004.…”

Diarrhoea rates are influenced by weather and climate; transmission can be affected by temperature and rainfall extremes, although few studies have quantified this effect. We undertook a global cross-sectional study of diarrhoea incidence in children under 5, drawing on studies published in the last 50 yr, and assessed the association with climate variables. Log-linear regression was used to quantify any association, controlling for the effects of age, socio-economic conditions and access to improved water and sanitation. We found a negative association between rainfall and diarrhoea rates, with a 4% increase in diarrhoea incidence (95% confidence interval, CI: 1-7%, p = 0.02) for each 10 mm mo -1 decrease in rainfall. Little evidence for association with temperature or climate type was found. Our result for rainfall is consistent with a similar study covering a smaller geographic region. Though biases cannot be excluded, the most likely mechanism is that low rainfall leads to water scarcity, which in turn leads to the use of unprotected water sources and reduces hygiene practices. In the future, greater numbers are expected to experience water scarcity, which may lead to more diarrhoea cases in some locations. This study lends support to programmes for hygiene and water and sanitation coverage, as well as lending support to actions to adapt to and mitigate climate change.

“…Climate may affect the dynamics of cholera by shifting pathogen or host reservoir species abundance, population dynamics, and community interactions (Bouma and Pascual, 2001;Pascual et al, 2002;Koelle et al, 2005a). For example, cholera outbreaks in Peru and Bangladesh have been linked to periodic climatic cycles such as the El Niño Southern Oscillation (ENSO) (Salazar-Lindo et al, 1997;Pascual et al, 2000;Rodo et al, 2002). In particular, variations in rainfall in the Indian Ocean during the monsoon may induce predictable variations in phyto-and zooplankton abundance in the marine environment, which appears to be correlated with the appearance of cholera cases in coastal human communities (Colwell, 1996;Faruque et al, 2005).…”

Cholera Threat to Humans in Ghana Is Influenced by Both Global and Regional Climatic Variability

Cholera, an acute diarrheal illness, is caused by infection of the intestine with the bacterium Vibrio cholerae after ingestion of contaminated water or food. The disease had disappeared from most of the developed countries in the last 50 years, but cholera epidemics remain a major public health problem in many developing countries, most often localized in tropical areas. Cholera is an infectious disease for which a relationship between disease temporal patterns and climate has been demonstrated, but only in an endemic context and for local areas of Asia and South America. Until now, similar studies have not been done in an epidemic context, on the African continent, although the largest number of cholera cases has been reported for those countries by the World Health Organization. The wavelet method was used in order to explore periodicity in (i) a long-time monthly cholera incidence in Ghana, West Africa, (ii) proxy environmental variables, and (iii) climatic indices time series, from 1975 to 1995. Cross-analysis were done to explore links between these time series, i.e., between cholera and climate. Results showed strong statistical association (coherency) from the end of the 1980s, between cholera outbreak resurgences in Ghana and the climatic/environmental parameters under scrutiny. Further examination of the existence of common spatial and temporal patterns in infectious diseases on the continent of Africa will permit development of more effective treatment of disease.
