The title of this miniature painting is
sadly ironic. The day before Valentine's Day, 2004 a black
swan infected with the H5N1 virus died at a zoo in Shenzhen,
near Hong Kong. At the time, China had reported outbreaks
of bird flu in Shanghai and three other regions. Concern
was high because nearly four out of five fowl in China are
raised on household farms where people live close to their
animals, and the poultry industry was projected to produce
more than 10 million tons that year. Strenuous efforts kept
outbreaks in check.
Exactly two years later in Italy, again on the day before
Valentine's Day, wild swans in the southern regions of Calabria,
Puglia, and Sicily were found dead. They, too, had been
inflected with the virus.
It's not clear why more wild swans than
wild ducks and geese have been found dead--victims of
H5N1--especially when one study has shown that infected ducks shed
more virus for longer periods without showing symptoms of
illness.
