Three cities at higher dengue risk - study
Three Brazilian host cities - Fortaleza, Natal and Recife - are at higher risk than the other nine of a dengue fever outbreak during the World Cup, scientists said yesterday.
In absolute terms, the risk is low in all Cup venues, but comparatively greater in the three north-eastern cities and authorities should beef up steps to prevent an outbreak, they said.
Writing in the journal The Lancet Infectious Diseases, a team of European and Brazilian experts wrote: "Efforts to reduce dengue incidence and severity should be concentrated in these three cities."
Potential measures include attacking mosquito breeding sites in stagnant pools of water and rubbish.
"The risk is more likely to be low in all 12 host venues," lead author Rachel Lowe, from the Catalan Institute of Climate Sciences in Barcelona, Spain, said via e-mail. - AFP.
