How big, really, is the Zika outbreak in Florida?
WBUR - 08/23/2016
But many scientists are concerned that the outbreak in Florida may be larger and more widespread than the number of cases suggests.
“Zika is one of those diseases that is always like an iceberg — you just see the tip,” says Alessandro Vespignani, a computer scientist at Northeastern University in Boston, who has been tasked with modeling the spread of the virus.
Most people who get Zika don’t even know they have it, Vespignani explains. About 4 in 5 people don’t have any symptoms, he says. And those who do get sick often have only mild symptoms that could be confused with the flu. So only about 5 percent of cases get detected, Vespignani has found.
