The disease, called peste de petit ruminants, or PPR, is highly
lethal, with an 86 percent mortality rate among goats. It is
caused by a virus that is similar to measles in humans. The U.N.
Food and Agriculture Organization said 1 million goats and
600,000 sheep are at risk of contracting the disease. To protect
them, farmers have been moving their herds away from infected
villages, but that has only spread the epidemic to healthy
flocks of animals. FAO said it plans to vaccinate at least
500,000 animals and will try to limit the animals' movements.
