A rapid response is needed to minimize the impact of the Zika virus outbreak on the economies of Latin America and the Caribbean, said the World Bank.
With "a swift, well-coordinated international response," the impact of the mosquito-borne disease will be modest, perhaps taking $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.
Those with the largest risk due to a fall in tourism include Jamaica, Cuba, the Bahamas, Antigua, Belize and Barbados, according to the Bank.
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."
"Our analysis underscores the importance of urgent action to halt the spread of the Zika virus and to protect the health and well-being of people in the affected countries," said World Bank President Jim Yong Kim.
