When the mosquitos bite, the Biomedical Research Lab bites back

It’s summer, and with those longer days come backyard cookouts, outdoor activities and—ouch!—bug bites. Mosquitoes love Northern Virginia’s infamous hot and humid summers. And as the world’s deadliest animal, according to the Centers for Disease Control and Prevention, they’re more than just a nuisance at the family barbeque: They’re a health hazard.

But in partnership with Prince William County, �鶹��Ƶ’s Biomedical Research Laboratory (BRL) is working to prevent outbreaks of mosquito-borne diseases.

Since 2016, in response to the Zika virus outbreak, the county and the university partner each year to collect mosquito samples and test them for diseases like West Nile virus.

“West Nile is endemic in the United States, and infections can be lethal,” explained Farhang Alem, MS Biology ’15, PhD Biosciences ’19 , associate director of the BRL. Alem has led the mosquito testing program since 2019.

“Eighty percent of people will have no symptoms,” he said, “but about one in every 150 cases of West Nile is severe.” It’s a neuroinvasive disease, meaning severe cases can damage the nervous system, resulting in high mortality rates and a high likelihood of disability if survived. Even those with non-neuroinvasive West Nile virus, though most likely to make a full recovery, could experience symptoms for weeks or months.

“We want to prevent the spread as much as possible,” Alem said.

Testing season starts in late spring and runs through the fall. Each week, samples are collected at more than 60 sites across Prince William County, and the mosquitoes are sorted by species. Vector species—meaning those that carry disease—are sent to the BRL for testing. Researchers extract RNA from the mosquitos and check for the markers of West Nile virus. They then send their report to county officials. If mosquitoes are positive for West Nile virus, the county will follow their larvicide and adulticide spraying protocols to eliminate the threat at the site where the mosquitoes were trapped.

“It allows us to more precisely target areas before they become a concern for the local community,” said Eli Hosen, environmental project manager for the mosquito and forest pest management branch of Prince William County Department of Public Works. “The lab provides us with a quick turnaround so we can respond as soon as possible.”

The program has been effective, Alem said, in reducing the number of West Nile carriers in the region. "Spraying is definitely working to control the spread."

Alem is in conversation with other counties in Northern Virginia to see if there’s interest in expanding the surveillance program. The BRL is also hoping to learn best practices on mosquito trapping from Prince William County to implement in other areas of research.

George �鶹��Ƶ epidemiologist Amira Roess is looking into the possibility of a similar surveillance program in India for dengue fever, for example. And if deployed, researchers hope what they learn in India can be useful to their research here as well.

With almost 10 years’ worth of data from the ongoing testing, Alem is hoping the lab can one day look at trends in disease occurrence and correlating environmental factors.

“It's leading to new avenues of research for us,” said Alem.

Remembering Former President Jimmy Carter: Statesman, Humanitarian, and Peacemaker

�鶹��Ƶ’s Jimmy and Rosalynn Carter School for Peace and Conflict Resolution Remembers Former President Jimmy Carter: Statesman, Humanitarian, and Peacemaker

The Jimmy and Rosalynn Carter School for Peace and Conflict Resolution at �鶹��Ƶ remembers James “Jimmy” Earl Carter, Jr. 39th President of the United States, as an agent of peace. We send our deepest condolences to his family.

“President Carter’s unwavering dedication to peace has been, and will continue to be, our beacon and guide. Our school’s name is a tribute to President Carter’s commitment to the worldwide peaceful resolution of conflict, which is imperative in today's world, as we face many entrenched and emerging human security threats,” said Carter School Dean Alpaslan Özerdem. “We will further his legacy in conflict resolution through our research and practice. His insight, passion, and love for peace will remain our inspiration in educating future peacemakers.”

“President Carter showed us that the American presidency can be even more than the pinnacle of political power. It can also be a prelude to far greater humanitarian works,” said George �鶹��Ƶ President Gregory Washington. “Tirelessly, humbly, and often unheralded, he led the eradication of Guinea worm in Africa, assured free and fair elections, and devoted thousands of hours of manual labor to help build homes for those in need. In his life, he saved countless lives, brought dignity to countless more, and spread peace throughout our world.”

President, father, husband, author, teacher, Nobel Peace Prize recipient, humanitarian, and peacebuilder, Jimmy Carter led by example. Prior to his election to the presidency in 1976, he served as both Georgia Governor and Georgia State Senator. During his term as president, the Department of Education and the Department of Energy were created.

Carter expanded the national park system and environmental protection legislation. He negotiated the Torrijos-Carter Treaties (1978) and signed the SALT II Treaty with the Soviet Union (1979). He was, perhaps, best known for his mediation efforts in realizing the Camp David Accords between Egypt and Israel in 1978. Titled the “Framework for Peace in the Middle East,” these dialogues paved the way for peace between these countries, even when such an outcome seemed remote.

Post-presidency, Jimmy Carter conducted peace negotiations and worked to eradicate disease in developing nations. He founded the Carter Center in 1982, and through the center, helped mediate conflicts in Ethiopia and Eritrea, North Korea, Liberia, Haiti, Bosnia, Sudan, Venezuela, and many more war-torn countries. For decades, Jimmy and his wife, Rosalynn, were prominent and active figures in Habitat for Humanity across the globe.

In 2002, Jimmy Carter was awarded the Nobel Peace Prize for his “decades of untiring effort to find peaceful solutions to international conflicts, to advance democracy and human rights, and to promote economic and social development.” He is one of only four U.S. Presidents to receive this honor.

On October 1st, to celebrate his 100th birthday, �鶹��Ƶ awarded President Carter an honorary doctor of humane letters to honor his legacy of selfless dedication to peace and a more just and peaceful world.

Jimmy Carter’s dedication to peace and justice was an example to peacebuilders and mediators and his efforts inspired the renaming of George �鶹��Ƶ’s School for Conflict Analysis and Resolution in his honor in 2020. He will be remembered by the staff, faculty, and students at the Carter School and the entire peacebuilding community for his tireless and selfless contributions to peace.
