cord-275355-4izc5jxs	Hayden, Frederick	Transmission of Avian Influenza Viruses to and between Humans	2005-10-15		.txt	text/plain	2246	104	37	in this issue of the Journal of Infectious Diseases [1] , and the recent instances of cross-species transmission that caused human disease [2] raise fundamental questions regarding the routes of transmission of avian viruses to and between humans, possible differences in transmission patterns between human and avian influenza viruses, and implications for prevention in those occupationally exposed to infected animals and also in health care, household, and community settings. The findings that seropositivity occurs in small numbers of poultry workers exposed during outbreaks of illness in poultry caused by some avian strains (H7N7, H7N3, and H5N1) but not others (H7N1 and H5N2) argue for actual infection and support the notion that some avian influenza viruses are more likely than others to infect humans [1] . Most cases of human infection due to avian influenza viruses have involved close contact with infected poultry, particularly ill or dying chickens.	./cache/cord-275355-4izc5jxs.txt	./txt/cord-275355-4izc5jxs.txt
