Sound the Mosquito Alarm, Across the USA

Posted 3 days ago by Drugs.com

THURSDAY, Sept. 21, 2017 – Two species of disease-transmitting mosquitoes could likely flourish in most of the United States, government researchers report. Specifically, Aedes aegypti and Aedes albopictus could survive and reproduce for at least part of the year in three-quarters of the counties in the lower 48 states if introduced there, according to researchers from the U.S. Centers for Disease Control and Prevention. These two species can transmit viruses that cause Zika, dengue, chikungunya and yellow fever. The range where Aedes aegypti could survive includes much of the eastern United States south of the Great Lakes, as well as parts of several southwestern states. The range where Aedes albopictus could survive extends farther into the northeast but is more limited in the southwest. The study and accompanying maps were published online Sept. 21 in the Journal of Medical ... Read more

Beat Back Mosquitos After Hurricane Irma

Posted 6 days ago by Drugs.com

MONDAY, Sept. 18, 2017 – As if those who weathered Hurricanes Irma and Harvey don't have enough to worry about, one bug expert warns that the standing water left behind is the perfect breeding ground for mosquitoes. Residents need to drain birdbaths, pots and anything else in their yards that can provide egg-laying sites for the disease-carrying insects. "No container is too small to empty," Phil Kaufman, an entomology professor at the University of Florida, said in a university news release. Mosquito species that lay eggs in standing water in containers include those that transmit Zika, dengue and chikungunya viruses. Kaufman also recommended using mosquito briquettes to kill immature mosquitoes. The briquettes are available at many stores. When you go outside to empty containers or do yard cleanup, you should apply insect repellent (preferably with DEET) and wear light-colored ... Read more

Vision Problems Common in Babies Infected With Zika

Posted 10 days ago by Drugs.com

THURSDAY, Sept. 14, 2017 – When Zika infections strike in the womb, babies' eyes likely suffer, researchers say. Two studies of Brazilian infants with confirmed and suspected Zika virus infection in the womb found that all of them had vision problems. These problems included scarring, misalignment of the eyes, repetitive movement of the eye, and low vision. Of the 102 infants studied, about 40 percent had eye abnormalities and all had visual impairments, the study authors said. The findings were published online in the Journal of the American Association for Pediatric Ophthalmology and Strabismus. Because all infants had with visual impairment, these findings suggest "that the visual impairment is most likely related to the extensive damage to the central nervous system," said Dr. Liana Ventura, of HOPE Eye Hospital in Recife, Brazil. She was the lead investigator of one of the ... Read more

Could the Zika Virus Help Battle a Deadly Brain Cancer?

Posted 19 days ago by Drugs.com

TUESDAY, Sept. 5, 2017 – The Zika virus is well known for causing devastating brain defects in fetuses. But what if scientists could use that ability to do something good? Researchers report that they think they might be able to harness the virus' attraction to developing brain cells – instead of adult brain cells – as a potential treatment for a deadly type of brain cancer. In lab and animal experiments, scientists from Washington University School of Medicine in St. Louis and the University of California, San Diego, showed – that the virus was able to target and destroy stem cells that drive the growth of a deadly and common type of brain tumor, known as a glioblastoma. "Our study is a first step towards the development of safe and effective strains of Zika virus that could become important tools in neuro-oncology and the treatment of glioblastoma," said study co-leader Michael ...

Harvey's Floodwaters Harbor Many Health Hazards

Posted 30 Aug 2017 by Drugs.com

WEDNESDAY, Aug. 30, 2017 – Texans trapped in the unprecedented flooding wrought by Hurricane Harvey now face untold health hazards, officials say. The filthy water that has inundated the city of Houston poses the most immediate danger, said Cleveland Clinic infectious disease expert Dr. Frank Esper. "Those floodwaters are being contaminated with sewage, because the sewers themselves are completely flooded and are backing up through the drains into the standing bodies of water that are around and in people's homes," Esper said. "Every time a person is wading across the street to get from one place to another, or down the road to get to higher ground, they are encountering much, much higher loads of bacteria." But beyond that short-term threat, other hazards and medical problems will crop up due to the lack of modern amenities in Harvey's aftermath, experts said. Dr. Bruce Farber is ... Read more

Zika Hijacks Pregnant Woman's Immune System

Posted 21 Aug 2017 by Drugs.com

MONDAY, Aug. 21, 2017 – The Zika virus thrives in pregnant women by suppressing their already dampened immune systems and running roughshod over their body's natural defenses, which allows the virus to directly attack the fetus, a new study reports. A woman's immune system naturally suppresses itself during pregnancy to keep the body from recognizing the fetus as a foreign body and attacking it, explained senior researcher Jae Jung, chair of the department of molecular microbiology and immunology at the University of Southern California's Keck School of Medicine. Zika hijacks this process, turning off most of a pregnant woman's immune defense so the virus can spread unhindered, Jung said. "The virus really tricks the host's immune system," Jung said. "It commandeers the pregnant woman's immune strategy to protect the fetus and utilizes that strategy for its own benefit." This helps ... Read more

Zika May Not Last in Semen as Long as Thought

Posted 18 Aug 2017 by Drugs.com

FRIDAY, Aug. 18, 2017 – Zika virus might not remain in the semen of some infected men as long as previously thought, a small study suggests. The researchers said Zika may only be present in semen for about a month. Previous research had suggested that Zika virus can be found in semen for as long as 188 days after the onset of symptoms. The new study included 12 men in French Guiana who had Zika virus. Four of the men never had any detectable Zika in their semen. One excreted Zika virus in his semen for at least three days. And seven had Zika-laced semen for at least a month, the researchers reported. The maximum duration of detectable Zika in semen in the study was 45 days. "These data suggest that not all men who are symptomatically infected with Zika virus will have Zika virus RNA detectable in semen," Dr. Franck de Laval, of the Military Center for Epidemiology and Public Health in ...

'Herd Immunity' May Be Curbing U.S. Zika Numbers

Posted 17 Aug 2017 by Drugs.com

WEDNESDAY, Aug. 16, 2017 – The number of Zika infections has dropped dramatically in Florida this summer, and scientists say herd immunity may be the reason why. In practical terms, herd immunity means that people traveling to the United States from South America and the Caribbean may have been infected with Zika in the past, but they can no longer pass the virus on to mosquitoes that might pass it on to local residents. "People that were infected before can't be infected again. That's our understanding," Dr. Henry Walke, incident manager for Zika response at the U.S. Centers for Disease Control and Prevention, told the Miami Herald. The latest statistics in Florida seem to bear that theory out: The number of Zika cases reported in the state this year has reached 140, a drastic decrease from nearly 1,500 in 2016, Florida health officials report. At the time of the Florida outbreak, the ... Read more

Zika Virus Tied to Neurological Woes in Adults

Posted 14 Aug 2017 by Drugs.com

MONDAY, Aug. 14, 2017 – Adults infected with the Zika virus can develop a number of serious neurological conditions, a new study finds. Until now, the most troubling Zika-related illness in adults has been Guillain-Barre syndrome, which causes muscle weakness and paralysis. A review of 35 Zika-infected patients in Brazil with neurological symptoms found that most had Guillain-Barre. But other neurological conditions were also discovered, most often inflammation and swelling of the brain and spinal cord. "Overall, the risk of Guillain-Barre for a person who contracts Zika is probably still very low, but it's important to know there's neurological conditions associated with Zika virus," said study co-author Dr. Jennifer Frontera. She's chief of neurology for NYU Lutheran Medical Center in New York City. Frontera and other infectious disease experts said pregnant women still carry the ... Read more

Zika Probably Not Spread Through Saliva: Study

Posted 1 Aug 2017 by Drugs.com

TUESDAY, Aug. 1, 2017 – Scientists have some interesting news about Zika: You're unlikely to get the virus from kissing or sharing utensils with someone. A new study with monkeys suggests that Zika doesn't appear to be transmitted through saliva. "If passing the virus by casual contact were easy, I think we would see a lot more of what we would call secondary transmission in a place like the United States," said lead researcher Tom Friedrich, from the School of Veterinary Medicine at the University of Wisconsin-Madison. "But we're not seeing clinically apparent spread of Zika throughout the continental U.S. without the presence of the mosquitoes that carry the virus, and our study helps to put into context some of the transmission risk," he added in a university news release. Mosquitoes are the main cause of Zika infection in people. After infection, the virus remains in blood and ... Read more

Impaired Eyesight May Be First Sign of Zika Damage in Babies

Posted 17 Jul 2017 by Drugs.com

MONDAY, July 17, 2017 – Infants exposed to the Zika virus in the womb should have their eyes examined for possible virus-related abnormalities, according to a new report. "All infants with potential Zika virus exposure should undergo screening eye examinations regardless of [central nervous system] abnormalities, timing of maternal infection during pregnancy, or laboratory confirmation," said Dr. Andrea Zin and colleagues. Zin is with the National Institute of Women's Health in Rio de Janeiro, Brazil. In some cases, evidence of Zika infection may only show up in the eyes, the study found. The results were published July 17 in the journal JAMA Pediatrics. "Eye abnormalities may be the only initial finding in congenital Zika virus infection," Zin said in a journal news release. Zika, a mosquito-borne virus, usually causes only mild symptoms in healthy adults. But fetal exposure during ... Read more

Experimental Vaccines Might Shield Fetus From Zika

Posted 13 Jul 2017 by Drugs.com

THURSDAY, July 13, 2017 – Two experimental vaccines might help protect human fetuses against the Zika virus, a new mouse study suggests. Researchers found female mice that were vaccinated before they got pregnant had babies with no sign of Zika infection. "There are several vaccines in human trials right now, but to date, none of them has been shown to protect during pregnancy. We tested two different vaccines, and they both provided substantial protection," said co-senior study author Dr. Michael Diamond, a professor at Washington University School of Medicine in St. Louis. Though Zika doesn't make most people seriously ill, it can be devastating for fetuses, causing problems with brain development, including an abnormally small head. Zika can also restrict babies' growth in the womb or trigger a miscarriage, researchers said. The team tested the ability of two experimental vaccines ... Read more

Malaria Drug Protected Mouse Fetus From Zika: Study

Posted 11 Jul 2017 by Drugs.com

TUESDAY, July 11, 2017 – A malaria drug protected mice fetuses from the Zika virus, researchers report. In humans, Zika infection during pregnancy can cause severe brain damage in infants. In this study with pregnant mice, investigators found that the malaria drug hydroxychloroquine prevented Zika from crossing the placenta. "We found that the malaria drug hydroxychloroquine effectively blocks viral transmission to the fetus," said senior author Indira Mysorekar. She's an associate professor of obstetrics and gynecology, and of pathology and immunology at the Washington University School of Medicine in St. Louis. "This drug already is used in pregnant women to treat malaria, and we suggest that it warrants evaluation in primates and women to diminish the risks of Zika infection and disease in developing fetuses," Mysorekar said in a school news release. Even though hydroxychloroquine ... Read more

Tissue Testing Can Spot Zika at Birth: CDC

Posted 22 Jun 2017 by Drugs.com

THURSDAY, June 22, 2017 – Exposure to the Zika virus in pregnancy can wreak havoc on babies, but diagnosing the infection before birth remains a challenge. Now, there's some good news: U.S. health officials say testing placental and fetal tissue after a child is born can confirm or rule out infection. Such testing found that only 1 in 10 who were in danger of being infected actually were, and infection didn't automatically mean birth defects, researchers from the U.S. Centers for Disease Control and Prevention reported Thursday. "Testing of placental tissues from live births can continue to be considered when results of maternal Zika virus testing are not definitive or testing is not performed within the optimal time," said the researchers led by Dr. Sarah Reagan-Steiner, of the CDC's National Center for Emerging and Zoonotic Infectious Diseases. Zika infection is most often spread by ... Read more
