More than two billion people could be at risk from Zika virus outbreaks in parts of Africa and Asia, according to scientists writing in The Lancet Infectious Diseases.
The research team, from the London School of Hygiene and Tropical Medicine, Oxford University and the University of Toronto, Canada, said “vast numbers” of people were living in environments where it would be hard to prevent, detect and respond to the virus.
Populations in India, Indonesia and Nigeria are some of the most vulnerable to transmission, the researchers said.
They used data on air traveller numbers to help model their predictions.
