Bluetongue Disease Outbreak Reported in France for the Sixth Time in Eight Days

Multiple Serotypes Confirmed

The French Ministry of Agriculture confirmed three outbreaks of serotype 3, a previously unknown variant in France, in sheep farms on Thursday, August 8th. Two additional outbreaks of a new variant of bluetongue virus were detected on August 9th, leading to increased concern among ruminant farmers.

Outbreaks Concentrated in Eastern France

• The latest outbreak occurred in the eastern region of Marne.
• This marks the sixth outbreak of bluetongue disease reported in France in just eight days.

Virus Transmitted by Midges

Bluetongue disease, primarily transmitted by midges, affects cloven-hoofed animals such as sheep, cattle, and goats.

Symptoms may include swelling of the tongue, lips, and face, as well as respiratory distress and lameness.

While the disease is not considered fatal in most cases, it can cause significant economic losses due to reduced animal production and trade restrictions.

Spread of Serotype 8

The new variant of bluetongue virus detected in France belongs to serotype 8, which has been circulating in northern Europe.

Serotype 8 has been reported in several countries, including the Netherlands, Germany, and Belgium.

The spread of this new variant has raised concerns among farmers, as it can lead to more severe disease outbreaks.

Control and Prevention Measures

French authorities have implemented strict control measures to prevent the further spread of the disease:

• Movement restrictions have been imposed on animals in affected areas.
• Vaccination campaigns are underway to protect livestock.
• Vector control measures, such as insecticide spraying, are being carried out to reduce midge populations.

Health Implications for Humans

Bluetongue disease is not known to cause illness in humans.
