Genetic sequencing suggests the outbreak of viral hemorrhagic disease in Spain is caused by a novel strain, easing immediate concerns about a lab leak but leaving the source of the infection a mystery. The outbreak, which has already claimed the lives of 29 wild boars, has rattled the nation’s powerful pork industry – the world’s third largest producer of pork and related products.
The initial alarm stemmed from early genomic analysis indicating a similarity between the virus found in Spanish wild boars and strains commonly used in research settings. Tho, new data released this Tuesday offers a different picture.
Wild Boar Samples Differ From Known Lab Strains
According to a press conference, preliminary genetic sequencing conducted by the IRB [Instituto de investigación Biomédica de Barcelona] indicates the virus samples collected from infected wild boars do not match those held in local laboratories. “Pending official confirmation from the Ministry, genetic sequencing…tells us that the wild boar samples do not match the samples from the laboratories that we have,” a senior official stated, while urging “prudence” as investigations continue.
the official emphasized that definitive conclusions will come from reference laboratories overseen by the Spanish Ministry of Agriculture and the European Union. These initial findings provide temporary relief to IRTA-CReSA, a public laboratory located near the forested area outside barcelona where the first cases were detected in late November.
A Highly Lethal disease, but No Human Risk
The disease, a form of viral hemorrhagic disease, poses no threat to human health. Though, it is indeed devastatingly lethal to pigs and wild boars, with a mortality rate approaching 100%. All confirmed cases to date have been limited to wild boars within a six-kilometer radius, and no infections have been reported on commercial pig farms.
The outbreak prompted the Spanish Ministry of Agriculture to consider the possibility of a leak from a research facility earlier in December, following the EU reference laboratory’s initial genomic sequencing. This possibility has now been tempered by the latest findings.
A Unique Genetic Fingerprint
The regional executive’s analysis suggests the virus “presents its own genetic fingerprint, with mutation and a large deletion that place it as a new or undocumented variant until now,” according to a statement from the Department of Agriculture. This revelation complicates the investigation, as it indicates the virus did not originate from a known source.
The origin of this new strain remains unknown,and investigations are ongoing to determine how it entered the wild boar population. The situation underscores the importance of continued surveillance and rapid response capabilities to protect both animal health and the economic stability of the Spanish pork industry.
Here’s a substantive news report answering the “Five Ws and How”:
Why: A novel strain of viral hemorrhagic disease is threatening the Spanish pork industry and has already killed 29 wild boars.
Who: The outbreak is affecting wild boars in a six-kilometer radius outside Barcelona, Spain. The Spanish Ministry of Agriculture,the EU reference laboratory,IRB,IRTA-CReSA,and regional executives are involved in the investigation.
What: A new, undocumented variant of viral hemorrhagic disease has been identified in wild boars. Initial concerns about a leak from a research facility have been eased by genetic sequencing, but the origin of the virus remains unknown.
How: The outbreak was first detected in late November. Genomic sequencing initially suggested a link to research strains, but subsequent analysis by the IRB indicates the virus has a unique genetic fingerprint, differing from known lab samples. Investigations are ongoing, involving reference laboratories overseen by the Spanish Ministry of Agriculture and the EU.
End: As of Tuesday, the outbreak is contained to wild boars within
