Florida Probes Four Suspected Non-travel Cases of Zika

Health officials are investigating non-travel-related Zika virus cases in Miami-Dade and Broward counties. Residents have been asked to cooperate in the investigation.

Two new cases of Zika virus in Florida that may not involve people infected while traveling outside the United States are being investigated by health officials. The total number of such cases has increased to four.

If any of the cases are confirmed, it would mark the first time that mosquitoes carrying the virus are known to be present in the continental United States.

Paraguay Reports First Two Cases of Microcephaly Linked to Zika Virus
Paraguay reported its first two cases of babies born with microcephaly linked to the Zika virus, which is blamed for a surge in birth defect across Latin America.

‘A total of 381 Zika virus cases have been reported in Florida. All such cases involved traveling to Zika-affected countries.’

Zika is spread via mosquitoes and by sexual contact. If pregnant women are infected, they face a higher risk of bearing an infant with microcephaly, a birth defect that causes an abnormally small head.

"The department is expanding its ongoing investigations with two additional possible non-travel-related Zika virus cases in Miami-Dade and Broward counties," the Florida Department of Health said in a statement.

"The investigations into the new cases will begin today, and door-to-door outreach and sample collection are ongoing in all cases," it added.

Olympic Travelers Face Tiny Zika Risk, Just 3 to 37 People Might Get Infected
Those traveling to Brazil for the Olympics face a tiny risk of getting infected with the mosquito-borne Zika virus, which can cause birth defects in pregnant women.

The department urged residents and visitors to participate if asked for urine samples in the areas being investigated. The results would help determine the number of people affected.

Last week, Florida reported its first two cases of Zika virus in people who did not immediately appear to have any travel-related exposure -- one in Miami-Dade County and one just to the north, in Broward County.

Swift Action Needed To Minimize Economic Impact Of Zika Outbreak: World Bank
The impact of the mosquito-borne Zika virus will be modest, if $3.5 billion, or 0.06 percentage points is taken off of gross domestic output (GDP) for the affected region this year.

Those investigations are still ongoing.

The state has already seen 381 cases of Zika, all involving people who were infected while traveling to parts of the world where the virus is circulating.

Rio Carnival Opens Under the Cloud of Growing Zika Fears
This year's Carnival in Rio starts under the cloud of the mosquito-transmitted Zika virus, which normally provokes few ill effects and serious birth defects.

For Zika to become a homegrown virus in the mainland United States, a mosquito would have to bite a Zika-infected person and then bite another person, passing on the virus.

Health officials have warned of possible localized Zika outbreaks in the United States, particularly since the virus has spread quickly throughout Central and South America and the Caribbean in the past two years.

However, mosquito control measures such as air conditioning, use of window and door screens and bug repellant are likely to prevent Zika from becoming established in the United States.
