****A free service of the APEC Emerging Infections Network*****
The EINet listserv was created to foster discussion, networking, and collaboration in the area of emerging infectious diseases (EID's) among academicians, scientists, and policy makers in the AsiaPacific region. We strongly encourage you to share their perspectives and experiences, as your participation directly contributes to the richness of the "electronic discussions" that occur. To respond to the listserev, use the reply function. In this edition:
1. OVERVIEW OF INFECTIOUSDISEASE INFORMATION Below is a semimonthly summary of AsiaPacific emerging infectious diseases. ASIA China (Hong Kong) — Avian influenza On Dec. 10, 2002, Penfold Park in the centre of Sha Tin racecourse was closed for a month after 31 ducks and geese died of the H5 virus in 2 weeks. A week later 20 chickens were found dead at a market stall in Mui Wo. The cull at the Ta Kwu Ling farm was also ordered because more than 1000 chickens died there and tests on 12 chickens from the farm proved positive for the H5 virus. Two outbreaks of pathogenic avian influenza were reported in broiler farms
in the New Territories. The date of initial detection of the incident was Dec.
26, 2002. Total number of bird deaths cases was 5,500 and then 22,500 birds were
destroyed. H5N1 avian influenza virus is a causal agent and it is genetically
different from HK/1997 (H5N1). In terms of source of agent/origin of infection,
infected wild bird involvement is suspected.
In November, the drug firm, Shanghai Desano Biopharmaceutical Co., said it had been given government approval to sell the first Chinesemade HIV drug combination. A competitor, Northeast China Pharmaceuticals Group Company, has also begun producing drugs. The mass production would reduce annual treatment expense by 90% and the annual expense for each patient is set to be around 3,000 and 5,000 yuan ($360$600). AIDS patients at the hospital currently spend between 30,000 and 40,000 yuan ($3,600$4,800) annually for the treatment using drugs from overseas. Dr. Zhao Hongxin, in charge of the AIDS center of Beijing Ditan Hospital, told Reuters Health on Monday that the hospital so far had received no official notification about the availability of Chinamade AIDS drugs from the Ministry of Health. The State Council approved one of ministry's projects that plans to spend 22 million yuan ($2.64 million) annually from 2002 to 2004 tackling the epidemic in the most seriously effected provinces, such as Henan, Hubei and others in central China, according to Xinhua. Although China's official record showing the number of AIDS and HIV cases in
2002 was one million, climbing up from 600,000 in 2001, the UN suggests the number
is closer to 1.5 million and could hit 10 million by the end of 2010. Japan (Wakayama) — 6th Case of Mad Cow Disease The first case of the disease was discovered in Chiba Prefecture in September 2001. Two more cases were discovered in Hokkaido and Gunma prefectures in November 2001, a fourth case again in Hokkaido in May, 2002 and a fifth case in Kanagawa Prefecture in August 2002. The ministry has carried out BSE tests on all cattle for human consumption
since October 2001.
EUROPE
Europe — Influenza B virus Out of 3,604 sentinel respiratory specimens for influenza virus since Sept. 30, 2002, 109 (3 %) have tested positive for influenza A (23%) or B (77 %). EISS has received no reports this season of the influenza A(H1N2) virus strain that circulated in Europe last season. Most of the cases of influenza B virus (86 %) reported so far this season, have been reported by Spain, France and Portugal. In France, Influenza B infections are cocirculating with influenza A viruses. All of the influenza viruses detected/isolated so far this season by EISS have been closely related to the 2002㪛 influenza vaccine strains. EISS aims to contribute to a reduction in morbidity and mortality
associated with influenza in Europe. Their Weekly Electronic Bulletin describes
the epidemiological and virological spread of influenza in the 19 countries (22
surveillance networks). During the current influenza season, EISS includes 28
national reference laboratories, at least 10,600 sentinel physicians and covers
a total population of 441 million inhabitants. 2. UPDATES
USA — CDC Update: West Nile Virus Case Count 3. JOURNAL ARTICLE PARIS — New Perspectives for Prion Therapeutics Meeting Since 1995, vCJD has killed more than 120 people in Europe and no one knows how many harbor latent vCJD infections from having eaten tainted beef during the height of the “mad cow disease” epidemic in the late 1980s and early 1990s. Masashi Nakajima, a neurologist reported dramatic improvements in patients with CreutzfeldtJakob disease (CJD) who had been treated with the drug quinacrine. However, the gains were shortlived and both patients returned to their previous states within weeks of starting treatment. JeanPhilippe Brandel, a neurologist in Paris, also reported disappointing results. In a nonblinded study of the same drug, researchers detected neither "clinical improvement in the CJD patients nor an increase in their length of survival. Quinacrine is one of many compounds capable of stopping the spread of prions
in cultured neuroblast cells or in infected lab animals. No one knows why quinacrine
shows modest, early success in some patients but fails to halt the disease. 4. NOTICES PulseNet Pacific Rim Planning Meeting Organizers: Centers for Disease Control and Prevention (CDC),
Atlanta, GA Overview and Purpose A meeting was held in Honolulu, HI on Dec. 12㪥, 2002 to explore the possibility
of setting up PulseNet Pacific Rim. The purpose of the Honolulu meeting was to
discuss issues involved in the standardization of methods, data generation, and
terms for data sharing and collaboration. Through interactive brainstorming sessions,
the benefits and challenges of forming PulseNet Pacific Rim were discussed, an
action plan for the establishment of PulseNet Pacific Rim was developed, and a
steering committee for this network was formed at this meeting.
The moderators for this meeting included speakers from CDC, APECEINet (University
of Washington), WHO, EnterNet, and the Washington State Department of Public Health.
Invited participants in this planning meeting included representatives from 12
Pacific Rim countries/areas. Each country/area presented their current level of
foodborne surveillance testing, as well as an outline of their capabilities for
future participation in molecularbased laboratory surveillance. The participants
agreed that a network for foodborne surveillance in the region should be formed,
and that this network would benefit by functioning as a part of the global PulseNet
network. Also, the participants decided that the PulseNet Asia Pacific would be
a more appropriate name for the network, particularly with the inclusion of the
Centre for Health and Population Research, Dacca, Bangladesh as one of the participating
institutions in the network.
Therefore, the Steering Committee for PulseNet Asia Pacific was formed as follows: Additional invited participants from the Asia Pacific region were:
