Another Miami Neighborhood Now Zika-Free

Posted 1 day 22 hours ago by Drugs.com

FRIDAY, Dec. 2, 2016 – The Little River section of Miami is no longer an area where local Zika infection is active, Florida health officials reported Friday. While Florida Gov. Rick Scott said the development was great news for the state, he also asked residents to continue doing what they can to stop the spread of the mosquito-borne virus, which has been linked to devastating birth defects in babies. "It is crucial that everyone remains vigilant and continues to do their part to wear bug spray and dump standing water so we can keep these areas clear, especially for pregnant women and their developing babies," Scott said in a statement. The Florida health department "now believes active transmission of Zika is only occurring in the southern part of Miami Beach, and I hope that local officials will consider every available resource to ensure aggressive mosquito control measures are ...

First Case of Zika-Linked Glaucoma Diagnosed in Infant

Posted 4 days ago by Drugs.com

WEDNESDAY, Nov. 30, 2016 – The first case of an infant who developed glaucoma after being exposed to the Zika virus while in the womb has been reported by an international team of researchers. No previous cases have seen a link between Zika infection and glaucoma, a condition that can permanently damage the optic nerve and result in blindness, the researchers said. But other vision problems and devastating brain defects have surfaced in babies born to mothers who were infected with Zika while pregnant. "We identified the first case where Zika virus appears to have affected the development of the anterior chamber, or front portion, of the eye during gestation and caused glaucoma after birth," study co-author Dr. Albert Icksang Ko said in a statement. He is a professor at the Yale School of Public Health, in New Haven, Conn. Ko has been working with doctors in Brazil since the Zika ... Read more

Texas Reports 1st Likely Case of Local Zika Infection

Posted 6 days ago by Drugs.com

MONDAY, Nov. 28, 2016 – Texas reported its first possible case of locally transmitted Zika infection on Monday. If confirmed, Texas would join Florida as the only states with local transmissions of the mosquito-borne illness linked to birth defects. The case involves a woman who lives in Brownsville, near Mexico, and she had no travel-related risk factors for Zika infection, the U.S. Centers for Disease Control and Prevention said. The virus is typically spread through the bite of the Aedes aegypti mosquito, although it can also be transmitted through sexual contact. "Even though it is late in the mosquito season, mosquitoes can spread Zika in some areas of the country," CDC Director Dr. Tom Frieden said in an agency news release. "Texas is doing the right thing by increasing local surveillance and trapping and testing mosquitoes in the Brownsville area." As of Nov. 23, an estimated ... Read more

Zika Babies May Look Normal at Birth, Display Brain Defects Later: CDC

Posted 12 days ago by Drugs.com

TUESDAY, Nov. 22, 2016 – Babies exposed to the Zika virus in the womb can look normal at birth but later show signs of the devastating birth defect microcephaly and other brain abnormalities, researchers reported Tuesday. Scientists found that 13 infants in Brazil who were exposed to the mosquito-borne virus during gestation had normal head size as newborns, but subsequently experienced slower head growth. Eleven of these babies were diagnosed with microcephaly – an abnormally small head and brain – and other neurologic complications associated with Zika syndrome, the researchers reported. "Among infants of mothers exposed to Zika virus during pregnancy, the absence of microcephaly at birth does not rule out congenital Zika virus infection or the presence of Zika-related brain abnormalities," according to a news release from the U.S. Centers for Disease Control and Prevention. The ... Read more

Imaging Studies Shed Light on Zika's Effects

Posted 12 days ago by Drugs.com

TUESDAY, Nov. 22, 2016 – More details on how the Zika virus affects infants and adults will be presented to international researchers meeting in Chicago next week. Three studies scheduled for presentation at the annual meeting of the Radiological Society of North America attempt to shed light on the mosquito-borne virus that's linked to severe birth defects in babies. Most cases to date have occurred in Latin American countries. In one study, researchers used CT imaging to examine the central nervous system of 16 newborns whose mothers were infected with Zika during pregnancy. The babies were found to have a number of brain abnormalities. "Our study proves that Zika virus infection can cause congenital brain damage in babies with and without microcephaly," study author Dr. Natacha Calheiros de Lima Petribu said in a society news release. She's with the department of radiology at Barao ... Read more

Zika No Longer 'Global Health Emergency,' WHO Says

Posted 14 days ago by Drugs.com

FRIDAY, Nov. 18, 2016 – Zika, the mosquito-borne virus that can cause severe birth defects in the infants of infected mothers, is no longer a "global health emergency," the United Nation's World Health Organization (WHO) declared Friday. A WHO advisory panel said that while the spread of Zika remains of great importance, it should now be classed with other mosquito-borne maladies such as malaria or yellow fever, The New York Times reported. "We are not downgrading the importance of Zika," Dr. Peter Salama, executive director of the WHO's emergencies program, told the newspaper. "We are sending the message that Zika is here to stay and the WHO response is here to stay." Not everyone agreed with the agency's decision, however. Dr. Anthony Fauci is a renowned virologist and director of the U.S. National Institute of Allergy and Infectious Diseases (NIAID). He believes it's too early to ... Read more

FDA Scientists Develop Mouse Model for Zika Research

Posted 16 days ago by Drugs.com

FRIDAY, Nov. 18, 2016 – A mouse strain developed by U.S. government scientists could help speed up research into vaccines and treatments for the Zika virus, researchers report. Newborn mice of the new strain created by U.S. Food and Drug Administration researchers are susceptible to Zika and develop neurological symptoms within 12 days after infection. But the mice eventually recover from the infection, so they provide an opportunity to study Zika's long-term effects as well as another way to assess experimental vaccines and treatments, the scientists said. "There are many unanswered and essential questions about how the Zika virus works, including the long-term impact," Daniela Verthelyi, chief of the FDA's Laboratory of Immunology, said in an agency news release. "This mouse model gives researchers a new tool to study and understand how the Zika virus replicates and spreads in the ... Read more

Women at Greater Risk Than Men for Zika Infection: Study

Posted 18 days ago by Drugs.com

WEDNESDAY, Nov. 16, 2016 – Women are at greater risk for Zika infection than men, new research in mice suggests. Scientists found the virus appears to trigger a delay in the vagina's immune response. This delay allows the virus to go undetected, putting a fetus at greater risk for infection as well, the Gladstone Institute scientists explained. "Our research supports epidemiological studies showing that women are at a greater risk for Zika infection," senior study author Shomyseh Sanjabi, an assistant investigator at Gladstone, said in a news release from the San Francisco-based research organization. "What's more, the dampened vaginal immune response is especially concerning, because it gives the virus more time to spread to the fetus if a woman is pregnant or becomes pregnant during the course of infection," Sanjabi added. Zika virus is typically spread by the bite of an infected ... Read more

Zika Can Survive on Hard Surfaces for Hours

Posted 19 days ago by Drugs.com

TUESDAY, Nov. 15, 2016 – It's well known that the Zika virus can be transmitted through mosquito bites or, more rarely, sexual contact. Now, new research raises the prospect that the virus might be able to survive for several hours on hard, nonporous surfaces such as countertops, floors and doorknobs. There's good news, too, however: Common disinfectants are highly effective at killing any Zika that lands on these surfaces, the researchers said. The findings were presented Tuesday at the annual meeting of the American Association of Pharmaceutical Scientists (AAPS), in San Diego. "Zika can survive on hard, nonporous surfaces for as long as eight hours, possibly longer when the environment contains blood, which is more likely to occur in the real world," said lead researcher S. Steve Zhou in an AAPS news release. He is director of virology and molecular biology at Microbac Laboratories, ... Read more

Mosquitoes Can Deliver Zika/Chikungunya Double Whammy

Posted 20 days ago by Drugs.com

MONDAY, Nov. 14, 2016 – Mosquitoes can infect people with Zika and chikungunya viruses at the same time, new research suggests. And another study found that in addition to Zika virus, two other mosquito-borne viruses – chikungunya and dengue – can also cause severe neurological problems. In the first study, Colorado State University researchers discovered that Aedes aegypti mosquitoes can carry Zika and chikungunya viruses at the same time, and can secrete high enough levels of both viruses in their saliva to potentially infect people with both in a single bite. It's the first time this has been confirmed, the researchers said. In the second study, researchers in northeastern Brazil identified severe neurological problems in patients treated during a rare and unprecedented simultaneous outbreak of Zika, chikungunya and dengue in 2015. It was already known that Zika can cause ... Read more

DNA-Based Vaccine Protects Against Zika in Animal Study

Posted 10 Nov 2016 by Drugs.com

THURSDAY, Nov. 10, 2016 – An experimental Zika vaccine shows promise, researchers report. In animals infected with Zika virus, the synthetic DNA-based vaccine was 100 percent effective in protecting against infection, brain damage and death, the study found. "Our results support the critical importance of immune responses for both preventing infection as well as ameliorating disease caused by the Zika virus," said lead researcher David Weiner. He is executive vice president and director of the Vaccine Center at The Wistar Institute in Philadelphia. "As the threat of Zika continues, these results provide insight into a new aspect of the possibly protective ability of such a vaccine as a preventative approach for Zika infection," Weiner added in an institute news release. Therapies that look promising in animals often don't work in humans. However, the vaccine is being tested in two ... Read more

Antibody Treatment Shields Fetus From Zika -- in Mice

Posted 8 Nov 2016 by Drugs.com

MONDAY, Nov. 7, 2016 – An antibody derived from the blood of Zika-infected people may have the potential to protect developing fetuses from the ravages of the virus, a new study with mice suggests. The antibody, called ZIKV-117, protected fetal mice from a Zika infection in their pregnant mothers, said co-senior researcher Dr. James Crowe, director of the Vanderbilt Vaccine Center in Nashville. "The antibody treatment will clear the virus in the mother, but also protect the fetus, which is very important," Crowe said. The antibody is only a short-term antiviral treatment, but the researchers said it demonstrates the potential of a Zika vaccine to provide people long-lasting immunity against the virus. "No study so far has shown in any model that you could actually treat pregnant animals that are infected with Zika and protect the fetus," said co-senior researcher Dr. Michael Diamond, a ...

Could Zika Harm Men's Fertility?

Posted 31 Oct 2016 by Drugs.com

MONDAY, Oct. 31, 2016 – The mosquito-borne Zika virus harms the fertility of male mice and human studies are needed to determine if the same is true in men, researchers report. Three weeks after male mice were infected with Zika, their testicles had shrunk, they had lower levels of testosterone, lower sperm counts, and were less likely to be able to impregnate female mice, the scientists found. "While our study was in mice – and with the caveat that we don't yet know whether Zika has the same effect in men – it does suggest that men might face low testosterone levels and low sperm counts after Zika infection, affecting their fertility," said study co-senior author Dr. Michael Diamond. He's a professor of medicine at Washington University in St. Louis. Most of the previous research on Zika has focused on how it affects pregnant women and its link to severe birth defects. That's ...

Mouse Study Hints at Damage Zika May Cause to Adult Brain

Posted 25 Oct 2016 by Drugs.com

TUESDAY, Oct. 25, 2016 – Certain brain cells in adults may be vulnerable to damage from Zika infection, research with mice suggests. These stem cells replace lost or damaged neurons throughout adulthood. And they are believed to be critical to learning and memory, according to the scientists at The Rockefeller University in New York City and the La Jolla Institute for Allergy and Immunology in California. "This is the first study looking at the effect of Zika infection on the adult brain," said Joseph Gleeson, head of the Laboratory of Pediatric Brain Disease at Rockefeller. "Based on our findings, getting infected with Zika as an adult may not be as innocuous as people think," he said in a La Jolla Institute news release. Another one of the researchers agreed. "Zika can clearly enter the brains of adults and can wreak havoc," said Sujan Shresta, an associate professor of inflammation ... Read more
