context1: This <strong>infection</strong> of humans coincided with an epizootic (an epidemic in nonhumans) of H5N1 influenza in Hong Kong’s poultry population. This panzootic (a <strong>disease</strong> affecting animals of many species especially over a wide area) outbreak was stopped by the killing of the entire domestic poultry population within the territory. The name H5N1 refers to the subtypes of surface antigens present on the virus: hemagglutinin type 5 and neuraminidase type 1.
context2: The Catholic Church has been criticized for its pro-life efforts in all phases of society. The Church's denial of the use of condoms has provoked criticism especially in countries where AIDS and HIV <strong>infections</strong> are at epidemic proportions. The Church maintains that countries like Kenya where behavioral changes like abstinence are endorsed instead of condom use, are experiencing greater progress towards controlling the <strong>disease</strong> than those countries just promoting condoms.
