HPAI Updates, Surveillance, and Outbreaks Abroad

Update 2: January 12, 2017 Highly pathogenic avian influenza (HPAI) viruses continue to be detected around the world.  On January 9, USDA announced the detection of an HPAI H5 in Montana in a mallard duck that was part of routine surveillance activities.   It is hoped that this detection will be isolated, as was the detection in the same duck species in Alaska in late 2016.  Sadly, an H5N8 has impacted a swannery in Dorset, England,  and a Russian zoo recently depopulated its entire bird collection* due to HPAI. In addition to the H5 viruses that are spreading throughout Asia and Europe, other strains are making the news.  A rare case of H7N2 infected a Manhattan animal shelter, and caused illness in one of the attending veterinarians.    Update 1:  December 13, 2016  The United States continues to conduct surveillance for HPAI in wild birds as outbreaks continue in Europe and Asia.  Please see the bulletin from the USGS National Wildlife Health Center,   for important information on current HPAI events, domestic surveillance for HPAI in wild birds, safety guidelines and precautions, and more.  We recommend reading this bulletin in its entirety “The purpose of this Bulletin is to review events that led to the emergence of highly pathogenic avian influenza (HPAI) in North America in late 2014 and to provide an overview of HPAI mortality events and detections that are currently occurring in poultry and wild migratory birds of Europe and Asia”   Original Post:  Since we have moved into the migration season some of you have reached out to inquire about the status of highly pathogenic avian influenza.  Things have been quiet so far in the US, with the last positive sample having been collected from a wild mallard in Alaska this past August.  A table of positive surveillance results, updated weekly, can be found here: https://www.aphis.usda.gov/animal_health/downloads/animal_diseases/ai/uspositivecases17.pdf .  The ZAHP Fusion Center is also following the developments of current HPAI events in Europe and India.   As you may be aware,  in mid-October avian flu sub-type H5N8 (new to India) was discovered at a zoo in Gwailor, India after samples were taken from some of the 15 painted storks that died over the span of a few days.  The rest of the painted storks at the zoo were culled.  This month H5N8 has been discovered in wild birds in Croatia, Hungary, Germany, and Poland, as well as in Austria on Lake Constance near the borders of Switzerland and Liechtenstein.  More information about the events in India and throughout Europe can be found at the following links:   http://www.tribuneindia.com/news/nation/birds-in-gwalior-zoo-died-of-new-avian-flu-subtype-officials/313230.html http://www.telegraphindia.com/1161024/jsp/jharkhand/story_115177.jsp#.WCYSOYWcFYd  http://www.cidrap.umn.edu/news-perspective/2016/11/h5n8-spreads-wild-birds-germany-austria http://www.fao.org/ag/againfo/programmes/en/empres/news_031116b.html  


New World Screwworm

The United States Department of Agriculture announced yesterday that a case of New World Screwworm has been detected outside of a Control Zone that was established in the Florida Keys last year in response to the outbreak in the Key deer population.  The new case was found in Homestead, FL in a domestic dog. Screwworm is a concern as these fly maggots, unlike most maggots, will continue to feed on perfectly healthy tissue, severely debilitating the animal and usually leads to death if not treated.  Extensive efforts have been mounted by USDA to protect the endangered Key deer and other animals. The epidemiological report can be viewed here: https://www.aphis.usda.gov/stakeholders/downloads/2017/nws-epi-report.pdf. This fly will lay its eggs on multiple species (including rarely, man) so per the USDA press release sent out January 9th:   “Residents who have warm-blooded animals (pets, livestock, etc.) should watch their animals carefully. Florida residents should report any potential cases to 1-800-HELP-FLA (1-800-435-7352) or non-Florida residents should call (850) 410-3800.  Visitors to the area should ensure any pets that are with them are also checked, in order to prevent the spread of this infestation.”
