France Reports First Human Case of Shamonda Virus After Patient’s Death

Health authorities say the case appears isolated and poses no risk to the wider public despite the virus spreading among livestock across Europe.

French health authorities have confirmed the world’s first known human case of the Shamonda virus after a patient in France died, prompting increased scientific interest in a virus previously associated only with livestock.

The case was reported on Thursday by French officials, who stressed that there is currently no indication of a wider public health threat.

According to authorities, the patient, a man in his 60s, had been hospitalized in Lyon for an unrelated serious illness and is believed to have contracted the virus through a bite from an infected midge in eastern France.

Health experts suspect the infection occurred in an area where Shamonda virus had been circulating among animals during the spring and summer months.

Authorities Say Risk to Public Remains Low

Despite the unprecedented nature of the case, French officials emphasized that there is no evidence of human-to-human transmission.

French health directorate chief Gregory Emery described the case as highly unusual and linked it to the patient’s severely weakened immune system.

He reassured the public that the incident does not constitute a health crisis or outbreak.

The World Health Organization (WHO) has also been monitoring developments and remains in contact with French authorities.

According to the WHO, current evidence suggests the case is isolated and unlikely to result in broader transmission.

What Is Shamonda Virus?

Shamonda virus is primarily transmitted through biting midges and is most commonly found in cattle.

The virus has also been detected in sheep, goats, horses and alpacas.

It was first identified in Nigeria during the 1960s and has historically been regarded as an animal health issue rather than a human disease.

There have been no previous confirmed cases involving human infection.

Experts note that similar livestock viruses in Europe have not typically resulted in widespread human illness.

Virus Spreading Through Europe

Although the human case is believed to be isolated, Shamonda virus has spread among livestock populations in several European countries.

The virus was first confirmed in Europe in July after genomic testing identified infections in cattle in Germany, Switzerland and eastern France.

Since then, animal health authorities have reported detections in multiple countries, including Austria, Belgium, Ireland, Italy, Luxembourg, the Netherlands, Portugal, Slovenia and Spain.

The disease is not currently classified under the European Union’s Animal Health Law and is therefore not subject to official surveillance or mandatory control measures.

Impact on Livestock Farmers

The virus has caused concern within the agricultural sector due to its impact on livestock health and productivity.

Affected cattle have displayed symptoms including weakness, diarrhoea, reduced appetite and, in some cases, fever.

French animal health authorities reported that milk production on some dairy farms declined significantly following infections.

A recent study involving nine dairy farms found that milk output dropped by as much as 75% in certain cases, underlining the economic impact the virus can have on agricultural operations.

Investigations Continue

Health authorities and researchers are continuing to investigate the circumstances surrounding the first documented human infection.

Scientists hope further analysis will provide a clearer understanding of how the virus crossed into a human host and whether specific health conditions increased susceptibility.

For now, public health officials maintain that there is no evidence of ongoing transmission among people and no indication that the virus poses a broader threat to the general population.

However, the case is expected to attract significant attention from researchers worldwide as they seek to better understand the behaviour and risks associated with the Shamonda virus.
