There were 12 wild birds either found dead or dying with H5N1 during January to March 2007 in Kowloon (Top). Consequently, the government conducted a special cleansing operation on 2/3/2007 in Sham Shui Po and Mongkok. After the cleansing operation, only one dead bird was found in Hung Hom over the following two months (Bottom). While the cleansing operation might have appeared effective, other factors like migration of birds could have contributed to the phenomenon.

Is human susceptible? 人會感染禽流感嗎?
