Avian flu strikes Hong Kong poultry farm

first_imgDec 9, 2008 (CIDRAP News) – Health officials in Hong Kong today said they have detected an H5 avian influenza outbreak at a poultry farm in Yuen Long, marking the country’s first farm-based outbreak since 2003.York Chow, Hong Kong’s secretary for food and health, said in a press release today that the H5 avian flu virus struck 60 chickens, which died yesterday. He did not say if the virus at the farm was the highly pathogenic H5N1 subtype.Malik Peiris, a virologist at the University of Hong Kong, said it is “highly likely” that the virus is the lethal H5N1 strain, because other strains aren’t as deadly as the one involved in the outbreak appears to be, according to a report from Reuters today. “But this has to be confirmed,” he said.Chow said in the press release that he elevated Hong Kong’s avian flu alert to serious after receiving the H5 test results. He said the agriculture department will cull 80,000 chickens within a 3-km radius of the index farm and will destroy another 10,000 chickens from the area that have been transported to a wholesale market.Hong Kong’s government has also banned the export of chickens from all of the special administrative region’s farms and has halted all poultry imports, both effective for the next 21 days.He said Hong Kong’s Center for Health Protection would monitor the status of the farm’s owners and workers, none of whom have developed symptoms. Chow also said in the statement that veterinary officials have closed an aviary park near the farm and are monitoring the health of 1,500 birds that are kept in other parks in Hong Kong.The length of time since Hong Kong’s last farm outbreak is a sign that the prevention measures have worked well, he said in the statement. However, he said he was concerned about the latest outbreak, because the first chickens to die were those that had not been vaccinated.According to a Feb 5 report from the World Organization for Animal Health (OIE), the H5N1 virus is common and present year-round in Hong Kong, occurring in resident and migratory birds. The report said poultry farms are constantly monitored with serologic and virologic testing. All farm chickens routinely receive an inactivated H5N2 vaccine, and each flock contains 60 unvaccinated sentinels that are monitored over the lifespan of the group.In July, Yuen Kwok-yung, who heads the University of Hong Kong’s microbiology department, warned that the poultry vaccine has lost its effectiveness over the past 7 years of use, according to previous reports. He said that the virus in Hong Kong had shifted away from the Fujian strain that the vaccine was developed for and advised officials to ban live poultry from Hong Kong markets before the vaccine becomes completely ineffective.One month earlier, animal health officials had detected the H5N1 virus in poultry feces at several market stalls, but did not determine the source of the virus.Over the past few years, Hong Kong has filed several reports of individual sick or dead wild birds that tested positive for the H5N1 virus. The recent OIE report described two egrets—one found dead and one found sick in a Hong Kong park—that tested positive for the H5N1 virus in November and December 2007.See also:Feb 5 OIE reportJul 10 CIDRAP News story “Expert warns Hong Kong’s avian flu vaccine is waning”last_img read more

Boys hoops Lakers tops Marcellus, stays unbeaten

first_imgAnd it wasn’t a surprise that their first of two regular-season encounters would prove close from start to finish.Marcellus would twice in the first half build healthy margins, using a 9-2 run in the first quarter to go in front 15-9, and then working its way to a 28-21 lead late in the second period.Both times, Skaneateles caught up, and it was junior forward Nate Fouts that pushed his team in front by hitting three 3-pointers, accounting for nearly half of his game-high 20 points. Hunger and intensity burned throughout Friday night’s boys basketball battle between Skaneateles and Marcellus, the two neighbors and rivals each determined to maintain undefeated marks.And it was the Lakers finishing on top, leaning heavily on its defense during a couple of key stretches late in the game to push its way to a 59-53 victory over the Mustangs.Skaneateles entered the night at 3-0, with Marcellus at 2-0. Each of them had already earned key early-season OHSL Liberty division victories in narrow decisions over another big rival, Westhill. Marcellus absorbed this, and didn’t get derailed, either, when it went nearly six minutes without a field goal. Instead, down 46-41, it put together eight straight points and led 49-46 with less than four minutes left.Once more, though, the Lakers clamped down on defense, and put together a timely 9-0 spurt capped by Max Wamp’s 3-pointer. And after Matt Kershaw’s three-point play cut the Marcellus deficit to 55-52 with 1:52 play, the Mustangs were shut out the rest of the way.It was Fouts and Jack Whirtley. who had 14 points, pacing the Lakers’ attack. Kershaw got 15 points to lead Marcellus, with Will Kimber contributing 13 points.Share this:FacebookTwitterLinkedInRedditComment on this Story center_img Tags: boys basketballMarcellusskaneateleslast_img read more
