African Swine Fever (ASF), a highly contagious viral disease is responsible for millions of pigs death.
According to the Food and Agricultrural Organization of the United Nations(FAO),
"The spread of ASF shows no signs of slowing down. The contagious disease has led to the loss of over 7 million pigs in Asia alone, since sweeping into this region. More than 50 countries in Africa, Asia and Europe are currently affected and the Americas are trying to prevent incursion into their territory."
