Systematic Veterinary Virology

CONTROL AND ERADICATION

• Control is mainly aimed at vector control. Certain measures that have potential effectiveness against Culicoides include water management (reduction of Culicoides breeding sites), use of insecticides and larvacides (spraying breeding areas), and insect repellents in which animals are dipped.
• Vaccination should be practiced only in endaemic areas. In such areas serotyping of available BTV should be carried out followed by incorporation of all serotypes into the vaccine. Because of the multiplicity of BTV serotypes and variable cross-protection between serotypes, vaccination has resulted in varying degrees of success. No inactivated or subunit vaccines are currently available.
