More Data Needed To Determine Effectiveness Of Indoor Residual Spraying For Malaria Prevention, Cochrane Review Finds

Although it is widely accepted that indoor residual spraying (IRS) -- the spraying of the walls of homes with insecticides -- works in the prevention of malaria, "the number of high-quality trials are too few to quantify the size of effect in different transmission settings," conclude the authors of this Cochrane review (4/14). "Given the World Health Organization's 2007 decision to move towards world-wide malaria eradication, policy makers now also require good evidence on the combination of both IRS and ITNs [insecticide-treated nets]," according to a Wiley-Blackwell press release. "Currently we have no evidence to show whether or not a combination would be justified both from the cost and the impact side and this needs to be urgently generated," study co-author Christian Lengeler said in the release (4/13).
