EFSA assesses strategies for eliminating lumpy skin disease
The European Food Safety Authority (EFSA) has assessed the most effective strategies for eliminating lumpy skin disease (LSD) now that the outbreaks in south-eastern Europe have been contained.
A report published in the EFSA Journal gives advice on the ideal duration of vaccination programmes to eliminate the disease, and looks at the probability that the disease will reappear and at possible surveillance methods.
Outbreaks of LSD in the Balkan region fell by 95 percent from 7,483 in 2016 to 385 in 2017. In 2018 no outbreaks were reported in south-eastern Europe, although one outbreak was reported in the European part of Turkey.
The report says that the more effective the vaccination is in protecting animals against the disease – and the more herds are vaccinated – the shorter the vaccination programme can be. For example, if the vaccination is effective for 80% of vaccinated animals, a two-year programme with coverage of 90% of herds is sufficient.
The probability that LSD will reappear after a vaccination programme is mainly linked to the likelihood of infected animals being introduced from neighbouring affected areas. Other factors examined in the report include the possible persistence of the virus in vectors (such as ticks and insects) or in the environment.
The report also gives an overview of surveillance methods. These include measures for early detection of new cases and how to demonstrate absence of disease.
