Experts Study Hong Kong Flu Threat Webster helped detect the first human infection of the avian influenza virus H5N1 in Hong Kong last May. In a teleconference held Monday, he said that if the virus continues to infect humans, "it is only a matter of time" before human-to-human transmission occurs, the critical step in the initiation of a flu pandemic. We've already had six or seven cases of transmission, presumably from avian reservoir to humans, but we have no evidence yet of human-to-human transmission," said Dr. Robert G. Webster, chairman of the department of virology and molecular biology at St. Jude Children's Research Hospital in Memphis, Tennessee. None of the patients with confirmed H5N1 infection had contact with each other, nor did they share any medical characteristics that might make them more susceptible to a viral infection, such as impaired immunity. www.personalmd.com /news/a1997121510.shtml   (508 words)

AADMC: WYPR 1998: Avian Flu - Concerns about a possible pandemic Because live chickens frequently are kept in close proximity to human habitation and restaurants in Hong Kong, these fowl were considered to be a primary source of infection. There was no evidence of human-human transmission and no reassortment of the RNA. Indeed, studies are underway using archival specimens of tissue obtained from fatal cases in the 1918 pandemic to determine whether such a reassortment of influenza viral RNA had taken place. www.aaaai.org /AADMC/inthenews/wypr/1998archive/avianflu.html   (227 words)

CDC - Lack of Evidence for Human-to-Human Transmission of Avian Influenza A (H9N2) Viruses in Hong Kong, China 1999 During the 1997 FLUAV (H5N1) outbreak in Hong Kong, a case-control study found that visiting a poultry stall or market with live poultry during the week preceding illness was the main risk factor for H5N1 infection ( 12). During that outbreak, the Hong Kong Department of Health enhanced its active surveillance for influenza-like illness and influenza viruses in hospitals, general outpatient clinics, and physicians' offices.

Quang Ninh Physician Death Linked to H5N1 The physician fatality, linked to three patients not treated by the physician, is a classic example of efficient transmission of a virus in a health care setting (nosocomial infection). The death of a health care work linked to a hospital where there was no reported contact with H5N1 patients is a clear example of efficient human-to-human transmission of H5N1 avian influenza. The linkage of the 34 year-old physician to a facility with two confirmed and one suspect bird flu case is clearly cause for concern. www.recombinomics.com /News/04060503/Quang_Ninh_H2H.html   (413 words)

WHO Avian influenza A(H5N1) - update 15: Additional confirmed human case in Thailand; China announces suspected spread of infection in poultry; investigation of possible human-to-human transmission WHO stresses the need to continue to investigate each human case of H5N1 in order to identify the source of infection. WHO has investigated a cluster of respiratory illness in members of a family from Thai Binh province, Viet Nam. However, the investigation failed to reveal any direct contact with poultry for the man’s other sister and his wife. www.who.int /csr/don/2004_02_02/en   (689 words)

This is getting Serious.... Both lived in the northern province of Thai Binh, where a cluster of cases is causing great concern about the possibility of human-to-human transmission of the H5N1 virus, which experts fear could mutate into a form which could cause a pandemic. The 41-year-old nurse, also from Thai Binh province, was hospitalized on Thursday in Hanoi with a high fever, coughing and a lung infection - typical bird flu symptoms - a doctor said on condition of anonymity. Northern Thai Binh province, which has been a hotbed for the virus with two deaths and four other infections reported since December, is typical of most rural areas. www.ranchers.net /forum/post-6720.html   (3638 words)

Human to Human H5N1 Transmission "Probable" The girl, who lived in the northern province of Kamphaeng Phet, resided with her 32-year-old aunt, whose infection has been confirmed. The 11-year-old girl lived with her aunt, also confirmed Monday as having bird flu but recovering, in a village in northern Kamphaeng Phet province where a large number of chickens had died from bird flu. She looked after her until she died and remained in the province until after her cremation. discuss.agonist.org /yabbse/index.php?board%3D6%3Baction%3Ddisplay%3Bthreadid%3D20477   (5812 words)

The Observer International Family's hell at bird flu deathbed Thi Ngoan said she could not be sure of the source of her brother's infection but five days before he was ill he too slaughtered a duck and prepared duck's blood pudding - a delicacy enjoyed all over Vietnam on the eve of Tet, the start of the lunar new year. Ducks might be playing a 'silent role' in the transmission of the virus. Instead, virus experts could not rule out the possibility that he caught the disease from his brother, fuelling fears that H5N1 is on the brink of mutating into a new strain capable of causing a worldwide contagion. www.guardian.co.uk /Observer/international/story/0,6903,1426313,00.html   (5812 words)
