The occasional spill-over of the virus into humans results in more than 60 000 clinical cases of Japanese encephalitis annually, with high case fatality rates. The main vectors preferably feed on livestock and breed in rice fields, and the majority of cases subsequently occur in rural areas.

In 2006-2008, outbreaks were reported mostly during the winter season, but in 2009-2012 they occurred year round. H5N1 AIV succeeded in infecting not only domesticated birds but also many other avian species and mammals. Infections of humans were accompanied by mutations in the hemagglut...

These diurnal birds search their food in light abundant environment and raise their broods in dark cavities. However their visual performance in dim light conditions is largely unknown. Here, we compared light intensity threshold of activity in two groups of passerines, i.e. secondary cavity and non-cavity n...
