Public health authorities stressed that there did not appear to be any health risk to the public, adding that the infection had been "an exceptional case" involving a person with a severely compromised immune system.

There was "no health risk to the general public identified at this time", the health and agriculture ministries said in a joint statement. It added that the human infection appeared to be "an exceptional case involving a severely immunocompromised patient" hospitalised for a serious medical condition. "Despite circulating in Africa and Asia for several decades, the Shamonda virus has never previously been detected in humans," the ministries said.
The virus, which belongs to the Orthobunyavirus group, was first detected in Europe this summer, they said.

At this stage in the investigation, the patient was believed to have contracted the virus through the bite of a midge in eastern France, where the virus was circulating in animals during the spring and summer, the ministries said.
"The neurological complications observed in the immunocompromised patient prior to his death are very likely linked to infection with the Shamonda virus," they added, citing preliminary findings. But "clinical, biological and epidemiological investigations are still ongoing", they said. The virus was first detected in Nigeria in the mid-1960s and has since been reported in cattle in several parts of Africa and in Japan.
The virus was detected in Europe for the first time at the end of July, including on cattle farms in France. It has now been detected in 14 western European countries, according to an epidemiological bulletin from France's national research institute monitoring animal health. Cattle are considered its main animal hosts, although sporadic infections in smaller livestock and horses have also been identified in France this summer.
In cattle, the main symptoms are acute diarrhoea, fever, lethargy and a drop in milk production. A study of French nine dairy farms found milk output fell by up to 75 percent in affected herds. There are currently no commercially available vaccines against Shamonda virus, WOAH said.
