NIH scientists accused of smuggling monkeypox into US through Detroit Metro Airport
Two researchers from the National Institutes of Health are facing federal charges after allegedly attempting to smuggle monkeypox into the United States. The individuals are accused of conspiracy and making false statements to federal law enforcement officers.
Details of the Federal Charges
Vincent Munster, 53, a citizen of the Netherlands and chief of the Virus Ecology Section at the Rocky Mountain Laboratory in Hamilton, Montana, is among those charged. He is accused of illegally transporting biological materials alongside Claude Kwe, 38, a research fellow and citizen of Cameroon.
Both men are employed at a Biosafety Level 4 laboratory. This facility focuses on the study of cross-species transmission and emerging viral pathogens.
The Airport Incident
The events unfolded on January 25, 2026, at Detroit Metropolitan Airport’s McNamara Terminal. Munster and Kwe had just arrived from Brazzaville, located in the Republic of Congo, where a monkeypox outbreak was ongoing.

Upon arrival, U.S. Customs and Border Protection officers inspected the pair. The researchers allegedly informed officers that the black plastic case they were carrying contained diagnostic and testing equipment.
Investigation and Findings
A joint investigation by the FBI and Customs and Border Protection discovered that the case did not contain equipment. Instead, it held numerous vials of biological material.
Federal authorities tested 20 of the vials. The results showed that 17 contained deactivated monkeypox virus, one contained chickenpox virus, and two contained human DNA.
Significance and Legal Consequences
Monkeypox, also referred to as mpox, is a viral disease characterized by fever, rash, and swollen lymph nodes. Runyan described the allegations as “dangerous and unlawful smuggling” of viral material.
Marcus L. Sykes, a special agent in charge of the U.S. Department of Health and Human Services Office of Inspector General, stated that the case reflects a failure of those entrusted with federal programs.
The FBI Detroit Field Office is currently leading the investigation. If convicted, both Munster and Kwe could face up to five years in prison.
a criminal complaint is an allegation and not evidence of guilt. The defendants are presumed innocent unless proven guilty in a court of law.
