As Big Pharaoh reports, avian influenza is airborne. The transmission of H5N1 occurs through respiratory action on behalf of the infected hosts.
Currently, this has resulted in the release of an advisory recommending under-indulgence in consumption of atmospheric air unless absolutely necessary (i.e. if you have a medical condition and need to). People refraining from unnecessary air intake have been found to display proportionately lower infection and fatality rates.
Egyptian authorities have responded positively to this threat vector. The mobilization of air force assets aimed at the reduction of air borne hosts bearing H5N1 constitutes an effective and organized government response to this threat.
Please pass this information on.
