Daylight-powered microbe-killing masks and suits may someday help protect health workers from deadly germs like Ebola, according to new research.

Scientists have developed membranes that produce a tiny bit of disinfecting hydrogen peroxide when exposed to light. They could find their way into food packaging as well, the researchers say, helping cut down on foodborne diseases.

The research is published in the journal Science Advances.

“If there’s any live bacteria or virus on the surface, it’s still transmissible and could cause infection,” said University of California, Davis, researcher Gang Sun. Pexels

Nearly 500 health workers died during the 2014 Ebola outbreak in West Africa. Front-line caregivers wear full-body protective suits when they come into contact with patients with virulent diseases, but the process of removing the gear is a prime opportunity for infection if the surface is contaminated.

Sun and colleagues developed membranes that could line the outside of that protective gear. When exposed to daylight, molecules on the surface of these membranes react with oxygen in the air to produce small amounts of hydrogen peroxide — less than what you’d use to remove laundry stains, but enough to kill germs, according to Sun.

“The approach is quite novel,” said University of Maryland food scientist Rohan Tikekar, who was not involved with this research. He says others have developed materials that produce disinfecting chemicals, but most only work under high-energy ultraviolet light. Pexels

The new membrane also works in the dark, for at least an hour or two, thanks to chemical properties that recharge its germ-killing powers.

“That is a really significant improvement,” Tikekar added.

In addition to coating protective gear for health workers, Sun says adding a layer of this material to fresh-produce packaging could reduce contamination and prolong storage life.

Some versions of the material use natural compounds. Sun says one of the next steps is to make it edible. VOA

Lowering The Community Resistance To Ebola Is Extremely Important: UNICEF

In its latest assessment, the World Health Organization counted 197 confirmed and probable cases, including 92 deaths.

The U.N. Children’s Fund (UNICEF) says it is increasing Ebola prevention efforts in eastern Democratic Republic of Congo. The agency says community resistance to efforts to contain Ebola is growing and must be fought to stop the spread of the fatal disease.

Since the disease outbreak was declared on August 1 in Congo’s North Kivu and Ituri provinces, UNICEF has been working with communities to inform them about how the virus spreads and what measures to take to protect themselves from being infected.

The U.N. agency is working with community and religious leaders in the city of Beni, where health workers are facing hostility and resistance. UNICEF spokesman Christophe Boulierac said the spread of false rumors and fear about Ebola are endangering efforts to contain the virus.

“We are working with anthropologists, particularly in this Beni neighborhood, who ensure that the response is sensitive to cultural beliefs and practices, particularly around caring for sick and diseased individuals, and addressing population concerns about secure and dignified burials,” he said.

Boulierac said UNICEF is expanding its community outreach program to support thousands of people at risk in the city of Butembo. Two new Ebola cases recently were confirmed in this important commercial center with nearly one million inhabitants.

He said UNICEF is deploying a team of 11 specialists in community communication, education and psycho-social assistance. The agency also will provide water, sanitation and hygiene to help contain the disease and avoid further spread of the epidemic.
