University of Pennsylvania engineers have developed a rapid, low-cost genetic test for the Zika virus. The $2 testing device, about the size of a soda can, does not require electricity or technical expertise to use. A patient would simply provide a saliva sample. Color-changing dye turns blue when the genetic assay detects the presence of the virus.

The United States is on the verge of a national crisis that could mean the end of clean, cheap water.

Hundreds of cities and towns are at risk of sudden and severe shortages, either because available water is not safe to drink or because there simply isn’t enough of it.

The situation has grown so dire the U.S. Office of the Director of National Intelligence now ranks water scarcity as a major threat to national security alongside terrorism.

The 2016 National Health Security Preparedness Index shows gaps in health readiness among states.

Summer is rapidly approaching, and so is ideal mosquito weather and the opportunity for the spread of Zika — something hospitals need to be ready for.

The 2016 National Health Security Preparedness Index, released by the Robert Wood Johnson Foundation, shows that the United States scores 6.7 out of 10 for preparedness against public health emergencies, a 3.6 percent increase since the survey began three years ago. But, some of the regions most susceptible to the spread of Zika scored below the national level, including the Deep South.

Having many states improve their scores is a positive sign that the nation is improving, but there is concern that the South isn’t as prepared for the approaching mosquito season, says Glen Mays, professor of health policy at the University of Kentucky's College of Public Health, who leads the team overseeing the Index.

Presence of Wolbachia bacterium in the insects seen limiting their ability to transmit the rapidly spreading virus

Introducing a common bacterium into a species of mosquitoes drastically limits the insects’ ability to transmit the dangerous Zika virus that has been spreading rapidly, according to researchers at Brazil’s leading medical-research institute.

In a new study published on Wednesday in the journal Cell Host & Microbe, researchers at the Oswaldo Cruz Foundation (Fiocruz), in Rio de Janeiro, said their experiments have shown that injecting Aedes aegypti mosquito eggs with the Wolbachia bacterium makes the eventual adult mosquitoes highly resistant to the Zika virus, thereby limiting their ability to spread it.
