**6. Flooding**

Flooding causes local or widespread disruption of normal life and makes waste disposal difficult. A SR of waterborne infections and climate change found evidence of outbreaks and increased sporadic disease following flooding [37], and included cholera and other diarrhoeal diseases. Other reviews have found similar results [36] and the health impacts of flooding showed that monitoring, mitigation and communication had the potential to reduce loss of life [81]. Tsunami related flooding can have a disproportionate impact on women, children and the elderly [82]. The impact of flooding is generally greater in developing rural countries with poor infrastructure compared to developed countries where people in flooded properties can be readily moved to non-flooded areas for a temporary period and provided with potable water. This is particularly true of coastal areas [83]. After Hurricane Katrina, there was an outbreak of norovirus deriving from populations being held in a stadium [84] and an increase in *Vibrio* infections resulting from coastal waters [85]. An increase in flood related disease might be expected under climate change with altered weather patterns and more severe weather events. Early warning systems with effective disease surveillance, prevention and response are important in preventing infectious diseases following flooding [86].
