West Nile Virus May Pose Zika-Like Threat to Fetus

Posted 31 Jan 2018 by

WEDNESDAY, Jan. 31, 2018 – Zika may not be the only virus that can harm a fetus, a new study in mice suggests. "We found that West Nile virus and Powassan viruses shared with Zika the ability to infect the placenta and cause fetal death," said senior researcher Dr. Jonathan Miner, who's with Washington University School of Medicine in St. Louis. Both of those viruses are spread by the bites of ...

Bio-Engineered Mosquitoes to be Released In U.S.

Posted 9 Nov 2017 by

Bio-engineered mosquitoes will be released in many parts of the United States next year in an attempt to reduce wild populations of mosquitoes that can transmit diseases such as Zika, yellow fever and Dengue fever. The lab-grown male Asian Tiger mosquitoes are infected with bacteria that prevents reproduction, but does not pose a risk to other insects or animals, according to Kentucky-based ...

West Nile's Long-Term Bite: Impact on Brain May Last Years

Posted 7 Nov 2017 by

TUESDAY, Nov. 7, 2017 – Some people with a history of West Nile virus may show symptoms such as muscle weakness or foggy memory years later, a preliminary study suggests. West Nile is a mosquito-transmitted infection that turned up in North America in 1999. Since then, outbreaks have occurred across the United States each summer – with more than 47,000 reported cases overall, according to the ...

Treeless Tropics, More Disease-Carrying Mosquitoes?

Posted 2 Nov 2017 by

THURSDAY, Nov. 2, 2017 – Deforestation doesn't just strip the landscape. In tropical regions, it may also lead to more disease-carrying mosquitoes, University of Florida researchers say. "Converting pristine tropical forests into areas for agriculture or other uses creates a habitat for the mosquitoes that transmit human diseases," lead study author Nathan Burkett-Cadena said in a university ...

Some U.S. Olympians Got West Nile in Brazil, But Not Zika

Posted 10 Oct 2017 by

MONDAY, Oct. 9, 2017 – The Zika virus was less of a threat than feared for Olympic athletes at the 2016 Summer Games in Brazil. But other mosquito-borne infections struck a number of Americans, a new study reveals. Of more than 450 Olympians and staffers who provided blood samples, 7 percent tested positive for West Nile virus, dengue fever or chikungunya, researchers found. These other tropical ...

Health Tip: Keep Mosquitos Out of Your Yard

Not All Mosquitoes Need Standing Water to Breed: Study

Posted 12 Apr 2017 by

WEDNESDAY, April 12, 2017 – The standard wisdom on curbing mosquitoes is to eliminate pools of standing water where they might breed. But new research on a major family of mosquito species finds that may not always be enough. The study, by a team at the University of Florida, found that most species within the Culex family lay their eggs in more varied locations than just "floating egg rafts," ...

New Technology Makes Gene Mapping Cheaper, Faster: Study

Posted 23 Mar 2017 by

THURSDAY, March 23, 2017 – Scientists say they've developed a much cheaper and faster technology for mapping the genetic makeup of a living organism. They demonstrated the technology by decoding the DNA of the mosquito species that transmits the Zika virus. The original Human Genome Project took 10 years and cost $4 billion, but this new 3-D assembly method did the same in a few weeks for less ...

Drought May Beckon Bigger West Nile Outbreaks

Posted 8 Feb 2017 by

WEDNESDAY, Feb. 8, 2017 – A parched climate might be the perfect environment for spreading West Nile virus, a new study suggests. Researchers examined 15 years of data on West Nile virus infections in people across the United States and found that epidemics were larger during years of drought. There were also bigger outbreaks in areas that had not experienced large epidemics of the ...

New Clues to Huge Jump in U.S. Mosquito Population

Posted 6 Dec 2016 by

TUESDAY, Dec. 6, 2016 – New research hints at why the number of mosquitoes has jumped 10-fold in the past 50 years in certain U.S. states: Increased urbanization and shrinking levels of the pesticide DDT in the environment could be major factors. "At first glance, recent increases in mosquito populations appear to be linked to rising temperatures from climate change, but careful analyses of data ...

U.S. Death Toll From Infectious Diseases Unchanged: Study

Posted 22 Nov 2016 by

TUESDAY, Nov. 22, 2016 – The war against infectious diseases – medicine versus microbes – has been holding steady, with the U.S. death rate from these diseases about the same now as it was in 1980, new research says. But some of the specific disease threats have changed over the years, the study authors noted. Researchers found that the national death rate from infections stood at almost 46 ...

West Nile's Long-Term Death Toll May Be Higher Than Thought

Posted 14 Nov 2016 by

MONDAY, Nov. 14, 2016 – A new study suggests that the death toll from the mosquito-borne West Nile virus might be much greater than thought because its effects may often kill people months or years after infection. "We are hoping our research findings will help encourage a push to develop a vaccine that can help prevent disease and premature death," said study co-author Dr. Kristy Murray, an ...

When It Comes to West Nile, Robins Do It, Cardinals Don't

Posted 9 Aug 2016 by

MONDAY, Aug. 8, 2016 – Cardinals, common backyard birds in parts of the United States, may help protect people against West Nile virus, a new study indicates. Researchers wanted to learn why the infection rate for the mosquito-borne virus in Georgia has remained low even though about one-third of birds in the Atlanta area have been exposed to the virus. A similar pattern is evident throughout ...

Zika Vaccine Efforts Get Boost From Prior Research

Posted 28 Jan 2016 by

THURSDAY, Jan. 28, 2016 – Efforts to create a Zika vaccine are getting a leg up from lessons learned during earlier battles against other mosquito-borne viruses, U.S. health officials reported Thursday. Researchers are working on two potential vaccines, each based on earlier vaccines created in response to prior outbreaks of West Nile virus and dengue, Dr. Anthony Fauci, director of the U.S. ...
