Lab-bred mosquitoes are flying in South Miami. It’s the latest effort to stop the type of mosquito that spreads the Zika virus.

Thousands of bacteria-infected mosquitoes will be flying near Miami to test a new way to suppress insect populations that carry Zika and other viruses.

Mosquitoes are, by far, the deadliest animals on Earth. More than 725,000 people die from mosquito-borne illnesses like malaria each year, and millions are affected by mosquito-borne illnesses, according to the World Health Organization.

Two years ago, when the Zika virus was first identified as the cause of microcephaly in babies, women were scared. Expectant mothers who got infected had no idea what the chances were of having a healthy baby.

Researchers have since learned that while Zika infection is dangerous, about 94 percent of babies born to women infected with Zika appear to be normal at birth.

State Zika Cases Reach 200 In 2017

Oct 29, 2017

Florida has had 200 cases of the Zika virus in 2017, with most stemming from people who contracted the disease elsewhere and brought it into the state, according to information posted on the Florida Department of Health website.

Florida health officials are reporting the state's first case this year of the Zika virus transmitted by a mosquito.


The company that wants to hold the first U.S. trial of genetically modified mosquitoes in the Florida Keys and Keys residents who oppose the trial don't agree on much.

But representatives from both sides said Thursday they are happy with the recent announcement that federal oversight of the proposed trial will be moved from the Food and Drug Administration to the Environmental Protection Agency.

"We think it's a good thing," said Derric Nimmo, principal scientist at Oxitec, the company that has developed a genetically modified Aedes aegypti mosquito.

A team of researchers has prevented Zika virus infection in monkeys —and they hope the new approach can be developed for use in pregnant women.

The small experimental trial found that monkeys given a cocktail of known Zika antibodies—special proteins the immune system makes to stop a virus—did not develop Zika after they were exposed to the virus.

State Reports 14 More Zika Cases

Aug 22, 2017

The number of Zika cases reported in 2017 in Florida jumped about 10 percent during the past week, with the total reaching 151, according to information posted Monday on the state Department of Health website.

When Monroe County held a nonbinding referendum last year on whether  to allow the experimental release of genetically modified mosquitoes, most voters said yes.

This was as the mosquito-borne Zika crisis was exploding. The Food and Drug Administration had already started to clear the way for the field trial.

But residents of Key Haven--the proposed site of the mosquito control experiment--voted against it. And the company that breeds the mosquitoes started looking for another site.

Travel-Related Zika Cases Top 100 For 2017

Aug 15, 2017

While officials say mosquitoes are not believed to be transmitting the Zika virus in Florida, the state's number of “travel related” cases this year has topped 100, according to information posted Monday on the Florida Department of Health website.

While mainland South Florida ramps up its battle against the mosquito that can carry Zika, the Florida Keys has already begun the region's most intensive mosquito control operation.

The Centers for Disease Control and Prevention are updating their guidance for pregnant women regarding the Zika virus. The new information means asymptomatic pregnant women don't have to get the commonly used IgM test. The announcement comes as public health officials are increasingly worried about the risk of false positives.
