Shenzhen source of infection for avian influenza in poultry deadAt 05:50 on January 2, 2012
Although the disease control department said the gene mutation in the virus, but can not spread from person to personSouthern News correspondent correspondent Yong Xin Nan Wu nanhu Shenzhen bird flu first appeared on the history of deaths in the New Year has aroused great concern for the virus to mutate, whether human to human transmission is also speculation that circulated on the Internet. Shenzhen Center for Disease Control yesterday released the news that has confirmed the source of infection is poultry, and through genetic analysis of the characteristics of the virus, the virus although there were a genetic mutation, but still can not spread from person to person.
Virus highly pathogenic for humansIn the past 72 hours, the Shenzhen CDC and Hong Kong Centre for Health Protection expert on December 31, 2011 confirmed infected with H5N1 highly pathogenic avian influenza virus genome sequence determination and bioinformatic analysis, we found that the patients infected with the virus, 2.3.2.1 sublines highly pathogenic avian influenza virus to humans is highly pathogenic. Through phylogenetic analysis found that the strain with the domestic ducks in bird flu virus isolated from a high homology (90%), are the source of H5N1 bird shows the strain infected directly by birds infected people. Prior to the popular southern mainland China 2005-2006 highly pathogenic avian influenza virus mainly 2.3.4 lineage.
Experts from the genetic characteristics of the virus found in patients infected by the virus compared to the previous occurrence of highly pathogenic avian influenza virus has some genetic mutations, but still its receptor receptor for the birds, people still can not spread between the general public no cause for alarm.
Adamantane class of drugs for more sensitiveIn order to reasonably guide clinical practice, the Shenzhen CDC experts resistance to the virus were analyzed, the results show that virus is adamantane class of drugs are more sensitive (including rimantadine, amantadine song, King Kong bromide, memantine, etc. ), but resistance to Tamiflu, the role of drugs still under study.
Parts of the Government to suspend imports of poultry products in ShenzhenSouthern News trainee reporter Wang Mu-wide view of Shenzhen, a bus driver and the highly pathogenic bird flu death, department of Hong Kong Centre for Food Safety announced the bird flu 14 days before the onset of permanent residence for the default range of 13 km control zone imports from beginning January 1, suspended imports of live poultry and poultry products for 21 days, including chilled and frozen poultry and eggs, there is evidence of patients had contact with poultry, import control area will be expanded.
In 2008, the Government and the Guangdong province of highly pathogenic avian influenza in all cases the import of live poultry and poultry products in the arrangements, a regional regulatory policies, such as Shenzhen, Guangdong Province, including the emergence of highly pathogenic avian influenza confirmed cases of human infection , the Government will suspend imports from the control zone (may be infected with 13-kilometer radius around the site) imports of poultry and poultry products for 21 days. Hong Kong CFS, said yesterday that the death of the driver is located in Shenzhen Baoan manhole centered within 13 km of Hong Kong for processing a daily average export two batches of about 7,000 birds, including the 2000 goose and duck.
CFS said that if the patient is no obvious history of exposure to poultry, then according to the patients before the onset of permanent residence within 14 days of the designated import control area, where evidence showed that patients had 14 days before the onset of exposure to poultry, import control area will involved will be covered, the poultry farms, markets, and patients had contact with other parts of the event to communicate with the mainland, the two sides agreed to take the current measures.
Chief Executive Donald Tsang said earlier that the level of avian influenza in Hong Kong by the general level to a serious level, the Government and the Shenzhen, Guangdong Province and the State Inspection and Quarantine of the notification system is perfect, urged the public not to worry too much. Prior arrangements for sale of live chickens will be extended 21 days, the Government said it is still too early to say. http://tech.qq.com/a/20120102/000015.htm
