EHD is thought to have been first found and tracked back to around 1890, and has been responsible for die-offs of many different species across North America. Diseases such as blackleg, blacktongue, bluetongue, mycotic stomatitis, or hemorrhagic septicemia were thought to have been the cause of many of these die-offs.
BVD is considered one of the most significant infectious diseases in the livestock industry worldwide due to its high prevalence, persistence and clinical consequences. [16] In Europe the prevalence of antibody positive animals in countries without systematic BVD control is between 60 and 80%. [17]
The ultimate factor that causes death is pulmonary edema. In May 2010, a vaccine to protect cattle against East Coast fever reportedly had been approved and registered by the governments of Kenya, Malawi and Tanzania. [12] This consists of cryopreserved sporozoites from crushed ticks, but it is expensive and can cause disease. [citation needed]
[62] [63] All livestock in the vicinity were culled on 4 August. A nationwide ban on the movement of cattle and pigs was imposed, with a 3-km (1.9-mi) protection zone placed around the outbreak sites and the nearby virus research and vaccine production establishments, together with a 10-km (6.2-mi) increased surveillance zone.

In cases where livestock have shown clinical symptoms, they are usually limited to symptoms such as fever, loss of appetite, lameness, and ulcers and crusty sores on the nose, mouth, and teats. [10] Ibaraki virus, which is a strain of EHDV serotype 2, causes Ibaraki disease in cattle in Japan. [11]
An estimated 400,000 cattle infected with BSE entered the human food chain in the 1980s. [citation needed] Although the BSE epizootic was eventually brought under control by culling all suspect cattle populations, people are still being diagnosed with vCJD each year (though the number of new cases currently has dropped to fewer than five per ...
Bovine respiratory disease (BRD) is the most common and economically devastating infectious disease affecting beef cattle in the world. [1] It is a complex, bacterial or viral infection that causes pneumonia in calves which can be fatal.
The number of BSE cases reported following slaughterhouse testing has been minimal over the past 5 years, in line with the natural prevalence of the disease: 2 cases in 2006, i.e. 0.0008 cases per thousand cattle slaughtered; 3 cases in 2007 (0.0013 %0); 1 case in 2008 (0.0004 %0) and 2 cases in 2009 (0.0013 %0), with testing alone costing the ...
