With "a swift, well-coordinated international response," the impact of the mosquito-borne disease will be modest, perhaps taking USD 3.5 billion, or 0.06 percentage points, off of gross domestic output (GDP) for the region this year.
But the island countries of the tourism-dependent Caribbean, where the disease has spread rapidly, could be hit by losses of more than one percent of GDP, the Bank said.
Caribbean and other tourism-dependent countries "may require additional support from the international community to stem the economic impact of the virus," it said.
The study of the economic impact assumes that the biggest risk from the disease is for women of child-bearing age, due to the association of Zika with a rise in the rate of children born with microcephaly, or abnormally small heads.
However, it said that if Zika is also tied to the paralysis-causing Guillain-Barre syndrome, if transmission by sexual contact is confirmed or if the public becomes even more worried about the disease, the economic impact could be "significantly larger."
