ASF is reported to have already wiped out a quarter of the world’s pigs, and the risk of it infecting pigs in other countries in Asia and elsewhere remains a serious threat. The disease is known to kill about 80 percent of animals which become infected.
In Mozambique, although some pigs were identified that survived infection with a virulent isolate, this apparent resistance was found NOT to be transmitted to offspring based on results of viral challenge experiments (Penrith et al., 2004).
