Impact of drought on vector-borne diseases - how does one manage the risk?
Autor(es): Brown L, Medlock J, Murray V
Resumo: This article aimed to review all literature on drought - vector-borne disease to enable an assessment of the possible impact of drought on the changing risk of vector-borne diseases in the UK. A systematic literature review was performed. Using a search strategy developed from a combination of terms for drought - selected outcomes, the authors systematically reviewed all available literature from 1990 to 2012 on the impact of drought on vector-borne diseases. The following databases were searched: PubMed, Web of Science, - EMBASE. After reviewing the abstracts, 38 articles were found to fit the inclusion - exclusion criteria. Evidence found drought followed by re-wetting can have a substantial effect on water table levels, vegetation, - aquatic predators; all factors which influence mosquito populations. Several studies found an association between a drought during the previous year - West Nile virus incidence. Urban mosquito vectors of dengue virus - chikungunya virus are adaptable by nature - are able to exploit a multitude of additional aquatic habitats created as a response to drought (i.e. water storage containers). Tick populations are likely to be negatively affected by drought as they are dependent upon high levels of humidity - soil moisture. Further research is needed to identify public health interventions - environmental control measures for an invasive mosquito problem or arthropod-borne disease outbreak in the UK.
