Experts study behavior of H5N1 virus in Vietnam, China

first_imgJun 24, 2005 (CIDRAP News) – As poultry were being culled in China and Vietnam to prevent further spread of avian influenza outbreaks this week, international experts were visiting both countries to better understand how the H5N1 virus is behaving.Ducks in central Vietnam were being culled after authorities discovered that one-fifth of the waterfowl in Quang Tri province carry the H5N1 virus, China’s Xinhau news service reported today, basing the story on a Vietnamese newspaper, Saigon Liberation. More than 23,000 birds have already been culled in 38 infected flocks, with another 144 flocks untested, Xinhua reported.As many as 120,000 to 150,000 birds may be culled, according to a report today by the Vietnamese news service Thanh Nien News, which also cited the Saigon Liberation as its source.In response to the outbreaks, the Agriculture and Rural Development Ministry extended an existing ban on egg incubation for breeding poultry and building new waterfowl or quail flocks through February 2006, according to the Vietnam News Service (VNS). In addition, the country’s state bank has asked that commercial banks refuse loans to farmers and businesses that produce breeding poultry and waterfowl, VNS reported today.This is the second outbreak in Vietnamese poultry in about a week. Prior to that, the country had been free of bird outbreaks since April, Xinhua reported. However, human cases of H5N1 infection have continued without a major break since mid-December 2004.Possible and confirmed human H5N1 infections in Vietnam are the focus of intense study by a visiting team of experts from Britain, Hong Kong, Japan, and the United States, according to a Canadian Press (CP) report today. The team of about half a dozen virologists and epidemiologists is investigating whether the H5N1 virus has changed in ways that make a flu pandemic more likely.The team is working in Vietnam at the government’s request, Maria Cheng, a World Health Organization (WHO) spokeswoman, told the CP.Their tasks include studying clusters of cases to determine the extent of human-to-human transmission and analyzing tests on hundreds of stored human blood samples that may indicate scores of undetected human H5N1 infections, the CP reported.Those findings are questionable because they relied on the Western blot test, which is not the gold standard for flu testing, the CP story said.Authorities are negotiating to transfer the blood samples to a site where appropriate tests can be performed—a lab with the biosafety rating to conduct neutralization assays considered the gold standard for flu testing, the CP reported.In China, international experts sent by the WHO and the Food and Agriculture Organization (FAO) were studying the H5N1 outbreak in Qinghai province this week and recently received approval to do the same in neighboring Xinjiang province, the International Herald Tribune reported yesterday.China has had three avian outbreaks of H5N1 in recent weeks, including one this week that involved the deaths of 180 ducks and geese, according to its reports to the World Organization for Animal Health (OIE). In all, at least 1,490 birds were culled, according to a Jun 21 story by Agence France-Presse (AFP).Authorities are also pressuring China for details of farmers’ reported use of the human antiviral drug amantadine to control and prevent poultry outbreaks of H5N1. Scrutiny has extended to questions over whether China has used oseltamivir, one of a newer class of human antiviral drugs, on poultry, the CP reported on Jun 23.The WHO asked China to investigate whether farmers have used oseltamivir in poultry, and the FAO has urged China to prevent such use, the CP story said. Several countries are stockpiling oseltamivir for use in the event of a flu pandemic. Current strains of H5N1 are resistant to amantadine, but it could also be useful in a pandemic, depending on the nature of the pandemic virus, experts say.A spokesman for the company that makes oseltamivir, Roche, said the company doesn’t sell the product to agro-chemical businesses, the CP story said.The report quoted WHO spokesman Dick Thompson as saying, “It’s clear to us that the [Chinese] Ministry of Health shares our concerns about this and they understand the importance of . . . the possible use of this antiviral in agriculture, that it might force or speed [development of] a resistant strain.”last_img read more

Chelsea doctor row Q&A

first_img What else might this be about? Mourinho has rarely been short of a scapegoat when one is required. Whether it be ‘media campaigns’, dodgy floodlights, other teams gifting his rivals results (see Sporting Gijon v Barcelona, 2012) or the always reliable complaints about referees, Mourinho is a master at deflecting attention from a poor performance from his side. This might be taking things a bit far, but one thing that has barely been discussed since Saturday is Chelsea dropping points at home. What happens next? Carneiro and Fearn will be absent from the bench this Sunday. All eyes will be on what happens the next time a Chelsea player goes down apparently injured and how the medical staff on the bench respond, and each time Mourinho faces the media he can expect questions on when Carneiro and Fearn are going to return. The Portuguese was unhappy that the pair went onto the pitch to treat Chelsea playmaker Eden Hazard late in last Saturday’s 2-2 draw with Swansea, and although he did not back down he did say that their exclusion from the bench was not necessarily permanent. Here Press Association Sport looks at what is really going on in the row which has dominated the sporting week. So, uhm, what’s up, doc? Chelsea, down to 10 men after the dismissal of goalkeeper Thibaut Courtois, were left hanging on for a 2-2 draw at home to Swansea last Saturday. Hazard went down injured late on, prompting Carneiro and Fearn to enter the pitch and treat him. But that left Mourinho fuming on the touchline as he gestured frantically and shouted angrily. After the match, Mourinho accused the doctors of being naive regarding the game situation as their treatment of Hazard meant the player had to come off the pitch, leaving Chelsea temporarily with nine players. That seems a bit harsh. Did the doctors do anything wrong? According to the Premier League Doctors’ Group, Carneiro and Fearn had no option but to enter the pitch and treat Hazard – and would have been in breach of their duty of care if they had failed to do so. Under existing guidelines, a player can request treatment, or the referee can decide to call for it if he believes the player needs it. Referee Michael Oliver signalled for the doctors to come on as Hazard remained down, which would seem to make it an open-and-shut case – the doctors did everything right. Does Jose even have a point, then? Mourinho has received some limited support from former managers and players, who said they at least understood his frustration as events occurred in real time. But his decision to make an issue of it in his post-match comments, and the apparent reduction of Carneiro’s role in the wake of the incident, has created a huge storm in which Chelsea are not looking too good. Shouldn’t Mourinho have been more concerned about Hazard? It’s not clear to what extent he was injured. We’re not going to say he was definitely trying to waste time by staying down, but, let’s be honest, it wouldn’t be the first time a player has done that. If Mourinho was worried about needlessly being reduced to nine, we might ask why he has not criticised his star player for staying down and requesting treatment if he did not really require it. And if Hazard did need treatment, the player might be left wondering why his manager didn’t seem to care. Jose Mourinho has spoken publicly for the first time since his criticism of Chelsea team doctor Eva Carneiro, confirming she and colleague Jon Fearn will not be on the bench for Sunday’s trip to Manchester City.
