Zika virus: Florida cases ‘likely’ to be first US-based infections

Four people suffering from the Zika virus in Florida are probably the first cases contracted within the US, health officials say.

So far, cases outside of Latin America and the Caribbean, where the virus is prevalent, have been spread by travel to that region or sexual transmission.

The four Florida cases mean US mosquitoes may be carrying the virus.

Zika causes only a mild illness in most people but the virus has been linked to severe brain defects in newborns.

The Florida department of health said “a high likelihood exists that four cases are the result of local transmission”, centered on one small area just north of downtown Miami.

More than 1,650 cases of Zika have so far been detected in the United States, but the Florida cases would be the first in the US not involving sexual contact or foreign travel.

“This is not just a Florida issue,” Gov Rick Scott said. “It’s a national issue – we just happen to be at the forefront.”

In the latest reaction:

Two of those suffering from the virus are in Miami-Dade county and the other two in neighboring Broward county. They are the most densely populated counties in Florida.

Gov Scott said the cases involved three men and a woman, and that none had been hospitalized.

To confirm whether Zika is being carried by mosquitoes locally, scientists are surveying houses and people within a 150-yard (metre) radius of the cases, the flying distance of the insect.

In February, the World Health Organization declared the Zika virus a global public health emergency because of the risk to newborn children.

In severe cases, children can die and babies who survive can face intellectual disability and developmental delays.

Gov Scott asked all residents of affected areas to get rid of standing water, where mosquitoes thrive, and for residents to wear insect repellent.
