A high-profile case involving two scientists from the US National Institutes of Health (NIH) has sent shockwaves through Washington, sparking a congressional review into how viral pathogens are transported across international borders. At its centre is the alleged smuggling of mpox virus samples into the United States by Dr Vincent Munster, 53, a Dutch national and chief of the virus ecology section at NIH's Rocky Mountain Laboratories (RML) in Montana, and Claude Kwe, 38, a research fellow from Cameroon.
Federal law enforcement alleges that the scientists arrived at Detroit Metropolitan Airport on January 25th after a nine-day research trip to the Republic of Congo, where they had been studying the mpox strain linked to the country's ongoing outbreak. Mpox, formerly known as monkeypox, is a viral disease characterised by fever, swollen lymph nodes, and a painful rash. In 2024 alone, Africa has reported 80,276 suspected cases of mpox and 1,340 deaths, highlighting the serious nature of the pathogen.
According to a criminal complaint filed on June 2nd, Customs and Border Protection officials questioned the researchers about a 'large black plastic case' they were carrying. The scientists reportedly claimed the container held 'diagnostic and testing equipment'. However, a subsequent inspection allegedly revealed 113 sealed laboratory vials packed inside styrofoam coolers. When asked for the required documentation for such biological materials, Dr Munster is said to have replied: 'Yes yes, it's all in my laptop, but you won't need them. I do this all the time.'
Authorities have confirmed that laboratory analysis of 20 of these vials found 17 to contain 'inactivated monkeypox virus', one contained chickenpox virus, and two contained human DNA. The contents of the remaining vials have not yet been publicly identified. The importation of biological agents, even those rendered non-infectious, is subject to stringent regulatory requirements in the US, demanding specific authorisation and documentation for transport, particularly on commercial flights, and declaration upon entry.
Both Dr Munster and Mr Kwe were charged on June 2nd with conspiracy to smuggle mpox into the US and making false statements to federal law enforcement. Jerome Gorgon Jr, a US attorney, emphasised the gravity of the allegations, stating that these NIH experts 'apparently broke our laws by smuggling viral pathogens on a packed commercial airplane from an outbreak in the Republic of Congo.' Both men pleaded not guilty at a hearing in Missoula, Montana, on June 3rd and were released on bail after surrendering their passports.
The incident has prompted a formal inquiry from the US House Committee on Energy and Commerce. In a letter dated June 16th to the NIH director, Dr Jay Bhattacharya, the committee requested detailed information regarding Dr Munster and Mr Kwe’s work, the origin and transport of the mpox samples, and any potential breaches in regulatory procedures.
