Czech Republic reports first H5N5 outbreak, as H5N8 turns up in Cameroon

In more quickly evolving avian influenza developments, the Czech Republic today reported its first highly pathogenic H5N5 outbreak and Cameroon became the latest country in Africa to report its first outbreak from the highly pathogenic H5N8 strain.

Meanwhile, a handful of European countries reported further spread of H5N8 in wild birds and poultry, according to the latest statements from the World Organization for Animal Health (OIE).

H5N5 in the Czech Republic

The Czech Republic's H5N5 outbreak involves a mute swan found dead on Feb 12 in a wintering place at a zoo in Liberec, in the north central part of the county. Officials culled four graylag geese and four mute swans that were also at the zoo's wintering site.

Eight countries in Europe have now reported recent H5N5 outbreaks.

H5N8 in Cameroon

Elsewhere, Cameroon reported its first H5N8 outbreak, which began on Jan 2, striking an exotic peacock farm in the Far North Region, officials said in an OIE report today. The peacock deaths prompted the testing, and tests on Jan 16 were positive for the H5 serotype, with H5N8 confirmed on Jan 19.

The virus killed 103 of 107 adults and juvenile peacocks. Authorities culled the remaining birds, as well 24 ducks and village chickens that were also at the farm.

Three African nations have now reported recent H5N8 outbreaks. The others include Nigeria and Uganda.

European H5N8 developments

Three European countries reported further spread of H5N8, including:

Bosnia and Herzegovina confirmed H5N8 as the subtype in a highly pathogenic H5 outbreak it reported earlier this week in backyard birds. Though several of the country's neighbors have reported H5N8 outbreaks, the event marks Bosnia and Herzegovina's first.

Croatia reported another H5N8 outbreak, this time in backyard poultry in the far eastern part of the country. The event began on Feb 9, killing 52 of 435 birds.

Poland reported five more outbreaks in poultry and eight more detections in wild birds, according to separate reports. Five poultry outbreaks—four on farms and one in backyard birds--had start dates between Feb 8 and Feb 11 and affected birds in three different provinces. All told, the virus killed 100 of 52,916 birds, and authorities destroyed the remaining ones as part of the outbreak response.  The wild bird detections spanned four different provinces and involved 28 wild birds, mostly mute swans, found dead between Feb 6 and Feb 11.
