As scientists struggle to understand the threat posed by Zika virus, there's another viral infection that's a known danger in pregnancy and that harms 100,000 babies a year, even though it has been preventable with a vaccine since 1969.

The disease is rubella, or German measles. Like Zika, the rubella virus often causes either a mild rash or no symptoms at all.

The U.S. Senate has passed a bill encouraging companies to develop a Zika vaccine.

Companies that develop a Zika vaccine would get fast-track FDA approval of their next venture in the future. That would be done through a voucher program.

A field trial releasing genetically modified mosquitoes in the Florida Keys would not harm humans or the environment, according to documents released Friday by the U.S. Food and Drug Administration.

Things To Know About GMO Mosquito Test Proposed In Florida

The spread of the Zika virus in Latin America is giving a boost to a British biotech firm's proposal to deploy a genetically modified mosquito to try to stop transmission of the disease.

  

A genetically engineered mosquito could stop the Zika virus from spreading. 

Florida has its first confirmed case of sexually-transmitted Zika virus.

Florida added two more cases of Zika Wednesday in Polk County. One was caught by a person who was traveling in Puerto Rico, but the other person caught the virus by sexual transmission. Because of patient confidentiality, officials can’t say if the two are related.

Florida is up to 50 cases of Zika virus, including six in Central Florida.

CDC: Zika Infections Confirmed In 9 Pregnant Women In US

Zika infections have been confirmed in nine pregnant women in the United States, including one who gave birth to a baby with a rare birth defect, health officials said Friday.

Three pregnant Florida women have contracted the Zika virus, according to the Florida Department of Health. Researchers are studying possible links between Zika in pregnant women and birth defects in babies.

2 More U.S. Cases Of Zika Virus Likely Shared Via Sex

Feb 23, 2016

Health officials announced Tuesday that they are investigating 14 new U.S. cases of possible sexual transmission of the Zika virus.

The virus was confirmed to be in blood samples from two women, using a method that detects pieces of the virus' genetic material, say doctors from the Centers for Disease Control and Prevention.

Obama Sends Congress $1.9B Request To Combat Zika Virus

President Barack Obama Monday sent lawmakers an official $1.9 billion request to combat the spread of the Zika virus in Latin America and the U.S.

There are 26 travel-related Zika cases in Florida, according to the latest information from the Florida Department of Health.

Central Florida is now up to three Zika cases. The virus has shown up in Brevard, Osceola and Orange counties. 

On Thursday, the U.S. Center for Disease Control and Prevention confirmed Brevard County’s first Zika case. The virus was caught while traveling to Haiti.

Two weeks ago, Jenny Tolosa found out she was pregnant.

The 23-year-old had no idea. "I didn't have any symptoms," she says. "I totally didn't expect this." She giggles, because she was excited by the news.

But she was also worried. She says her first thought was, "I think I had Zika last December!"

That's the mosquito-borne virus that's spreading through Latin America — and has been linked to the birth defect microcephaly, which causes an abnormally small head and possible brain damage.

CDC Briefs Florida Doctors As Zika Cases Rise

Study Finds Zika Virus In Fetal Brain, A Clue In Outbreak

New details about the possible effects of the Zika virus on the fetal brain emerged Wednesday as U.S. health officials say mosquito eradication here and abroad is key to protect pregnant women until they can develop a vaccine.

When Carolyn Coyne's lab at the University of Pittsburgh recently tried to order a sample of Zika virus from a major laboratory supplier, they were told it was out of stock.

"They are actually back-ordered until July for the virus," Coyne says. "At least that's what we were told." She ended up obtaining Zika from another source, and it arrived at her lab Tuesday.

Gov. Rick Scott added a fifth Florida county to a public health emergency declaration over the Zika virus on Thursday, and asked the Centers for Disease Control and Prevention for training and other assistance.

Broward joins Miami-Dade, Hillsborough, Lee and Santa Rosa counties as where cases of the mosquito-borne illness have been found. All of the cases are travel related.

Florida is one of several U.S. states now reporting a few isolated cases of people infected with the Zika virus. In response, Florida's Gov. Rick Scott has declared a public health emergency in five counties in hopes of getting ahead of the virus's spread.

So far, just 12 cases of the mosquito-borne illness have been reported to health authorities in Florida, all of them among travelers who contracted the disease outside the U.S. But Scott figures it's only a matter of time before the virus starts showing up among mosquitoes in some regions of the state, too.

  Gov. Rick Scott has declared a health emergency in five Florida counties with a dozen confirmed cases of the travel-acquired Zika virus: Hillsborough, Miami-Dade, Lee and Santa Rosa.

Long before this most recent outbreak, mosquito control officers across Florida have been on the front lines, trying to keep at bay diseases such as Zika, chikungunya and dengue. 

Mario Stevenson is a respected virus expert. He heads the infectious diseases division at the University of Miami’s Miller School of Medicine. He’s done pioneering research on HIV.

But until last year he’d barely registered Zika.

“Four months ago,” Stevenson told me, “I thought Zika was an Italian football player.”

A patient acquired Zika virus in the U.S. through sex with a person who had traveled to a place where the virus is circulating, Dallas County, Texas, health officials and the Centers for Disease Control and Prevention reported Tuesday.

This is not the first time that the virus has been sexually transmitted, and it most likely isn't the first time it's been sexually transmitted in the U.S.

Six new cases of travel-related Zika were confirmed this week in Florida.

That’s according to the Florida Department of Health, which reported the cases to the U.S. Centers for Disease Control.  That brings the number of Florida cases to nine total, none of them in pregnant women. All are believed to be contracted by someone traveling outside of Florida.

The outbreak of Zika virus in Brazil and other countries has raised concern that the pathogen could start spreading widely in the United States, as well. But federal health officials and other infectious disease specialists say so far that seems unlikely.

The rapid spread of the Zika virus has raised interest in a British company that has developed a genetically modified mosquito. Oxitec has produced a genetically engineered line of the Aedes aegypti mosquito, the mosquito that carries dengue fever and chikungunya. Those tropical diseases have become common in Latin America and are now showing up in Florida.

Aedes aegypti also carries Zika, a disease whose symptoms include fever, like dengue. It has also been linked to a birth defect, microcephaly in children born to women infected with Zika.

"We are alone. We have been abandoned by the state," says Marilia Lima, cradling her 2 1/2-month-old son, Arthur, against her chest.

Arthur is one of some 3,500 babies born with microcephaly, a birth defect that has been linked to Zika virus, since the virus was identified in Brazil in May. Although a definitive cause-and-effect relationship has not been proven, both Brazilian and international doctors believe there is indeed a connection.
