First human infected with livestock disease shamondavirus, French patient deceased
In France, a human infection with the shamondavirus has been confirmed for the first time. Earlier this month, a patient who had contracted the livestock disease died. It is still being investigated whether that was also the cause of death; the patient's health was already weakened by another condition.
The French authorities describe it as an "exceptional case" in a patient who already had a weakened immune system. "Based on current knowledge of this virus, there is so far no health risk for the general population," assure the ministries of Agriculture and Health.
The European health institute ECDC says it is closely monitoring the situation. It is working on additional testing capacity and offers member states assistance in tracking the outbreak among livestock.
European outbreak
Shamonda was first identified in the 1960s in cattle in Nigeria. Since then, it has appeared in Africa, Australia, and Japan, but this summer an outbreak was also detected in Europe for the first time. In July, the first cases were reported in cattle in southern Germany, Switzerland, and eastern France. Later, more countries followed, including the Netherlands and Belgium.
The disease causes diarrhea, fever, spontaneous abortions, and a drop in milk production in cattle. In horses, which can also suffer from it, the symptoms seem to affect the nervous system. Earlier this month, the disease was detected for the first time in a horse in the Netherlands. Sheep, goats, and alpacas can also contract the disease.
The disease is transmitted by bites from midges, small biting flies. The ECDC points out that these are mainly present in spring, summer, and autumn, and spread during the colder months is less likely.
European variant
It is still being investigated how the patient in France became infected. That appears to have happened in eastern France. There is no vaccine available against the disease.
The virus circulating in Europe is a different variant than the type already known to doctors. It is therefore officially called SHAV-EU, for European shamondavirus. According to the World Organisation for Animal Health, it is still too early to say whether this variant will manifest as a seasonal disease like the others.
