Thinking about Getting a Master’s in Biodefense?
GMU’s Schar School of Policy and Government has an upcoming recruitment event:

Pick Your Poison: The Enduring Threat of Biological Toxins
On February 26, the Bipartisan Commission on Biodefense at the Atlantic Council hosted its latest meeting titled “Pick Your Poison: The Enduring Threat of Biological Toxins,” mapping the evolving threat landscape of biological toxins and their implications for future biological attacks. Dr. Gregory Koblentz, Director of the Biodefense Graduate Program at George Mason University, participated as a featured speaker alongside policymakers and experts to examine the growing risks posed by biological toxins such as ricin, a highly potent toxin derived from castor beans. Discussions explored the full spectrum of toxin threats – from foodborne exposure and terrorism to state-sponsored assassination – as well as challenges in detection, attribution, and response.
Ahead of the event, the Atlantic Council published an accompanying dispatch highlighting why toxin threats are gaining renewed attention from the biodefense community, underscoring how advances in biotechnology and synthetic bio-production could increase the accessibility of toxin agents. They reinforced the importance of strengthening biodefense preparedness and response capabilities. Read the full op-ed here.

Allegations of Iranian Chemical Weapons Use Draw International Scrutiny
In a new op-ed, Andrea Stricker, and Schar School Biodefense Director, Gregory Koblentz, explore the question of, “Did Iran Use Chemical Weapons on Protesters?” From the National Interest: “More than 30 human rights and civil society groups are urging the United Nations to investigate allegations that Iran used chemical weapons against protesters in January 2026. This call mirrors concerns raised in a January 22nd, European Parliament resolution condemning the regime’s brutal suppression of national protests.”
Assad Loyalists Regroup as Syria’s Chemical Weapons Risks Persist
More than a year after the overthrowing of Syria’s President Bashar al-Assad, the status of their chemical weapons stockpiles remains uncertain. In The Bulletin of the Atomic Scientists, GMU Biodefense Director Gregory Koblentz argues that the international community must move beyond solely channeling resources to the Organisation for the Prohibition of Chemical Weapons (OPCW), the international body responsible for implementing the Chemical Weapons Convention (CWC), and provide direct capacity-building support to Syria’s new government to locate, secure, and destroy leftover chemical weapons stockpiles.

Homeland Security Today, a nonprofit news outlet, is pleased to announce the appointment of Dr. Mahmut Cengiz, a current Associate Professor at the Schar School of Policy and Government at George Mason University, as Managing Editor for Counterterrorism! Dr. Cengiz will help to strengthen the publication’s editorial leadership and analytical depth on global terrorism and security issues.
Foul Times for Pennsylvania Poultry Farms
By Margeaux Malone, Pandora Report Associate Editor
Pennsylvania has become the epicenter of the ongoing H5N1 avian influenza outbreak with more than 7 million birds in commercial and backyard flocks affected since the start of 2026. This represents more than half of all recently reported avian flu cases in the United States, with almost 9.5 million birds affected in the last 30 days across the country. Lancaster county has been hit especially hard with outbreaks at two commercial egg-laying facilities affecting 2.6 million and 1.4 million birds respectively, along with nearly 30,000 commercial turkeys and 179,000 broiler birds at other county sites. In total, Pennsylvania has lost more than 14.3 million birds since the current bird flu outbreak began in February 2022.
Governor Josh Shapiro, who met recently with farmers and agriculture officials in Lancaster County, declared that the state is “in crisis mode”. More than 100 state and federal personnel have been deployed across Pennsylvania to support response including a 25-person team from the USDA. The governor said he is in close contact with Agriculture Secretary Brooke Rollins regarding additional resources, including the possibility of a bird flu vaccine for poultry. However, Shapiro cautioned that any vaccine rollout would be months away and would likely begin as a pilot program, as international trade considerations continue to complicate the conversation at the federal level.
The economic ripple effects of the state’s outbreak are already being felt. Chris Herr, Executive Vice President of PennAg, noted that the impact extends well beyond individual farms to include feed companies, service businesses, and supply chains, with economists expected to tally losses in the tens of millions of dollars.
Federal Testing Mandates Improved Response in Dairy Herds
A report published in Emerging Infectious Diseases in early February offers an optimistic picture of how federal intervention has shaped the dairy cattle avian influenza outbreak. Led by researchers from The Ohio State University College of Veterinary Medicine, the team found that H5N1 viral RNA was present in 36% of retail milk samples collected across 13 states in spring 2024, including in five states with no officially reported outbreaks at the time. Only 29 infected herds had been reported as of April 12, 2024, suggesting the virus was far more widespread than surveillance data indicated.
Federal mandates launched in April and December 2024 required increased herd surveillance, including testing lactating dairy cattle prior to interstate movement and implementation of the National Milk Testing Strategy. While increased reporting requirements led to a rapid surge in documented cases to over 1,000 herds, viral RNA detection in milk samples subsequently dropped to just 6.9% in samples collected in late 2024 through January 2025. The findings suggest that expanded surveillance both improved detection accuracy and helped control the spread of H5N1 in dairy herds, highlighting the importance of instituting timely disease surveillance during outbreaks.
Human Case of H5N1 Confirmed in Cambodia
Cambodia reported its first human H5N1 infection of 2026 in mid-February, a 30-year-old man from Kampot province who has since fully recovered. The patient experienced fever, abdominal pain, and cough, and investigators linked his exposure to a dead chicken found in his home that had been cooked roughly three days before he fell ill.
While this individual case ended without fatality, Cambodia has recorded 36 human H5 infections since 2023, with a case-fatality rate exceeding 40%. Most recent Cambodian cases involve a reassortant strain (2.3.2.1e) blending an older locally circulating H5N1 clade with the newer globally circulating clade 2.3.4.4b, a combination that researchers continue to monitor closely.
