African swine fever : a re-emerging global threat
African swine fever (ASF) is a severe hemorrhagic fever of swine that is highly contagious. 4 ASF affects all breeds and ages of domestic swine, as well as a variety of wild swine. 4 In nature the disease is transmitted by argasid ticks (Ornithodoros species) that can also serve as a reservoir.7 In domestic swine, it can be transmitted by direct contact, indirect contact, and by consumption of infected meats or blood.4 Postmortem lesions include a marked splenomegaly and enlarged necrotic and hemorrhagic lymph nodes. 4 ASF is endemic to most of sub-Saharan Africa, and is found in feral pigs in Sardinia, Italy.6 Recently, ASF has spread outside the African continent reaching the Republics of Georgia, Armenia, Azerbaijan, and several territories in Russia.6 Its contagiousness and lack of prophylactic vaccines or effective control measures make this disease a very serious global threat.
