Five more bird species that can spread Lyme disease identified in USA

By Miroslav Djuric, DVM, CAB International, Wallingford, UK.

Lyme disease or Lyme borreliosis is the most prevalent arthropod-borne disease of animals and humans in the temperate regions of the northern hemisphere1. Risk of infection in humans is primarily associated with occupation (e.g. forestry work) or outdoor recreational activities.

Recent surveys show that the overall prevalence of Lyme disease may be stabilizing, but its geographical distribution is increasing. There are foci of Lyme borreliosis in forested areas of Asia, north-western, central and eastern Europe, and the USA. According to the CDC, Lyme disease is the most commonly reported vector borne disease in the United States. It is most commonly diagnosed in the northeast and upper Midwest, especially Wisconsin and Minnesota. However, Lyme disease is spreading geographically, especially into Virginia and the southeastern United States. The CDC estimates that about 300,000 Americans are diagnosed with Lyme disease each year, afflicting sufferers with flu-like symptoms. If not treated with antibiotics, the infection can cause inflammation of the joints and it can affect the heart and nervous system.

African Swine Fever on the Move – China, the EU and FAO Assessing Preparedness in East and Southeast Asia, the Region with >50% of the World Pig Population

By M Djuric, DVM

African Swine Fever (ASF) continues to spread in traditionally endemic sub-Saharan Africa, but it is also expanding into previously ASF-free countries with a new front opening up along the Caucasus and Eastern Europe.

ASF

 

The risk of ASF entering China is of particular concern since the country keeps almost half of the worldwide pig population. China is also the biggest importer of pork and has very strong links with ASF-infected countries in Africa. China also shares a border with the ASF-endemic Russian Federation.

China and Asia in general have never encountered ASF, and therefore there is a concern that the region may be unprepared for a potential outbreak of ASF, which could have catastrophic consequences on global pork supply.

To build ASF preparedness and to address the policy gaps, the European Union (EU) -funded LinkTADs research consortium brought together 40 experts from the EU and Asia for the “African Swine Fever Policy Event” in Beijing on 24 November 2014.
