However, some infections have also been identified when direct contact was not known to have occurred. Rare human infections with some bird flu viruses have occurred most often after unprotected contact with infected birds or surfaces contaminated with these viruses. This can happen when virus is in the air (in droplets or possibly dust) and a person breathes it in, or when a person touches something that has virus on it and then touches their mouth, eyes or nose. ![]() Human infections with bird flu viruses can happen when enough virus gets into a person’s eyes, nose or mouth, or is inhaled. Infected birds shed bird flu viruses in their saliva, mucous and feces.

The more active bird flea Ceratophyllus garei (Rothschild) from the nest of pheasant (Phasianus colchicus L), was tested for responses to light of varying intensity. ![]() In addition to species contrasts, females were more active than males and fleas were more active at 25oC than at 18oC. No unaided emigration or immigration has been demonstrated in these species (Clark, 1988) and much of their time is spent confined to the darkness of the nest. The apparatus was tested using Ceratophyllus hirundinis (Curtis), Ceratophyllusfarreni (Rothschild) and Ceratophyllus rusticus (Wagner), co‐inhabiting species from the nests of the house martin (Delichon u.urbica L.). Horizontal movements are detected using a system of infra‐red beams and phototransistors which, when broken, are counted as a measure of activity. The jumping response is detected by counting amplified pulses produced as the fleas land on a stretched membrane held over a microphone. The apparatus allows for a range of visual, chemo‐ and mechanoreceptor cues to be presented. An Insect Activity Monitor was created to measure the behavioural responses of fleas (Siphonaptera).
