Experts from across Africa say trans-border diseases kill between 10 and 20 percent of the continent's animals every year. The experts gathered in Cameroon last month to discuss the problem. They suggested large vaccination and pest eradication programs to stop the spread of the diseases.

Dr. Taiga is Cameroon's livestock minister. He does not use a first name. He says pests like nose bot flies and wool maggots are harming animals in some communities in his country.

Dr. Taiga says all animals in an area must be killed if one animal is affected because the diseases are contagious. They spread quickly from animal to animal. He says that is why the Food and Agriculture Organization (FAO) and the World Organization for Animal Health are working together to destroy the diseases. He says that when central African countries succeed in killing the pests, their human populations will enjoy better quality protein.

"The strategy is the large vaccination at the country level. Undertake surveillance to detect any case of the disease and strengthen collaboration between member nations and even between international institutions. Imagine somebody who has 10 animals and loses eight. The disease can have impact in food security."
