Food securityRinderpest: how the world’s deadliest cattle plague was eradicated

Published 14 September 2012

Rinderpest, the deadliest of cattle diseases, was declared vanquished in May 2011; after smallpox, it is only the second disease (and first livestock disease) ever to be eradicated from the earth; the insights gained from the eradication campaign may be applied to similar diseases that today ravage the livestock populations on which the livelihoods of one billion of the world’s poor depend; the lessons could also be applied to “zoonotic” diseases which are responsible for 2.4 billion cases of human illness and 2.2 million deaths per year

 

A new analysis published today in Science traces the recent global eradication of the deadliest of cattle diseases, crediting not only the development of a new, heat-resistant vaccine, but also the insight of local African herders, who guided scientists in deciding which animals to immunize and when. The study provides new insights into how the successful battle against rinderpest in Africa, the last stronghold of the disease, might be applied to similar diseases that today ravage the livestock populations on which the livelihoods of one billion of the world’s poor depend.

An International Livestock Research Institute release reports that rinderpest, capable of wiping out a family’s cattle in just a few days, was declared vanquished in May 2011. After smallpox, it is only the second disease (and first livestock disease) ever to be eradicated from the earth.

The elimination of rinderpest is an enormous triumph against a disease that has plagued animals and humankind for centuries,” said Jimmy Smith, director general of the International Livestock Research Institute (ILRI). “Science succeeded despite limited resources, and we now know how. We are committed to applying the lessons in this study to making progress against other similarly destructive livestock diseases.”

According to the analysis, which was conducted by international scientists coordinated by ILRI, and published this week in Science, the eradication of rinderpest happened thanks to the development of an effective temperature-stable vaccine, collaborations between veterinary health officials and cattle farmers to deliver those vaccines, and reliance on the knowledge and expertise of the local herders to determine the location and movement of outbreaks.

The cattle plague and its path of destruction
Rinderpest, known as “cattle plague” in English, is thought to have had its origin in the dense cattle herds of Central Eurasia more than two millennia ago and subsequently spread through warfare and trade to cattle in Europe, Asia and eventually Africa. Caused by a virus related to the one that causes measles and canine distemper, rinderpest could infect cows, water buffalos and other cloven-hoofed animals, leading to a high fever, severe diarrhea, then dehydration and emaciation. The pathogen could kill 90 percent of a herd, wiping out an entire farm’s livestock in just a matter of days. There was no treatment.

While rinderpest is not dangerous to human health, its impact on humanity has been significant. Its path of destruction has been linked to many history-changing events such as the fall of the Roman
