A Russian health worker gives a hen an immunization shot today as part of a mass vaccination campaign against bird flu (epa) April 6, 2006 -- Britain has confirmed a wild swan found dead in Scotland had the lethal H5N1 strain of bird flu -- the country's first case of the disease.

Authorities are now trying to calm the general public.

Bird flu has killed around 100 people the past three years. But the transmission from birds to humans remains rare and usually only when a person has had close contact with an infected bird.

Meanwhile, Egypt says a third person -- a teenage girl -- has died from the bird flu.

In Nigeria, authorities say the bird flu virus is now present in its most-populous city, Lagos.

So far no human cases of the disease have been detected in Nigeria. But the presence of the virus in Lagos -- home to an estimated 15 million people -- has health officials worried.
