    China relaxes quarantine on A/H1N1 flu close contacts, mild cases
    -----------------------------------------------------------------
    Chinese people in close contact with A/H1N1 flu patients will no
    longer be quarantined in specially reserved places, and patients with
    mild symptoms may receive treatment at home, the Health Ministry said
    Wednesday [8 Jul 2009]. Close contacts could observe home quarantine,
    and the range of close contacts was narrowed down, according to a
    notice on adjusting A/H1N1 flu prevention and control measures issued
    by the ministry Wednesday [8 Jul 2009].

    "The adjustment does not give up supervising close contacts. It's
    just a different place for quarantine, and they still will be
    restricted from going outside and contacting other people,"
    said
    Liang Wannian, deputy director of the ministry's emergency office.

    Close contacts now include people who diagnosed, treated, nursed or
    visited a patient, people who worked or lived with a patient, and
    people who contacted the spit or body fluid of a patient. And on
    aircraft, close contacts include 8 passengers surrounding a patient,
    the notice said.

    According to the notice, mild flu cases may be quarantined and
    treated at home, and health departments at provincial level have a
    general discretion to decide. Liang said the adjustment is aimed to
    ensure timely and effective treatment of severe cases. The notice
    also urged all regions to strengthen prevention and control work on
    special groups including the old, the sick and the pregnant.

    China had confirmed 1151 A/H1N1 flu patients by Tuesday [7 Jul 2009]
    and 870 of them had been discharged from hospital, according to the
    Ministry of Health. There have been no deaths directly caused by the
    influenza so far.

    [3] Thailand: 2925 confirmed cases, 14 confirmed deaths
    Date: Thu 9 Jul 2009

    The cabinet on Thursday [9 Jul 2009] approved the temporary closure
    of tutoring schools for 15 days starting Monday [13 Jul 2009] to
    limit the spreading of influenza A as the Public Health Ministry
    confirmed 3 more deaths from the virus. The move came after the
    Public Health Ministry reported that many students have caught the
    virus while at tutoring schools. All tutoring schools throughout the
    country will be closed from Monday until 28 Jul 2009, the cabinet decided.

    The temporary closure was necessary because most tutoring classes
    were in air-conditioned rooms, which facilitate the spread of the
    virus because the students are in confined spaces, Deputy Education
    Minister Chaiwuti Bannawat said.

    The cabinet also asked owners of online game shops to cooperate by
    closing their business during the same period, because many young
    players had also caught the infection.

    The Public Health Ministry on Thursday [9 Jul 2009] confirmed 3 more
    deaths from influenza A and 211 new infections.

    The 12th victim was a 52-year-old traffic policeman in Bang Na,
    Bangkok, who suffered from kidney failure
    . The 13th victim was a
    student in the 11th grade at Maha Sarakham University demonstration
    school in the northeastern province of Maha Sarakham.

    The 14th fatality was a 17-year-old girl who had been treated in
    Srinagarind Hospital in Khon Kaen province since 3 Jul 2009. She died
    on Tuesday, and her blood test on Thursday afternoon showed that she
    was positive for the A(H1N1) flu.

    The Maha Sarakham student was believed to have caught the disease
    when he went to take an assessment examination for Chulalongkorn
    University's faculty of medicine. At least 10 of his friends have
    been admitted to hospitals for tests. After his death, the school
    announced that it would close on Thursday and Friday.

    Total influenza A infections had risen to 2925, the health ministry said.

    Tourism and Sports Minister Chumpol Silpa-archa said the flu pandemic
    was expected to continue for months
    and would add to the burden of
    the country's suffering tourism sector. He said the flu outbreak
    would have a psychological effect on foreign tourists, who were
    likely to cancel overseas travel plans.

    [4] Viet Nam: 259 confirmed cases

    Patients suspected of having antiviral resistant H1N1 strain
    ------------------------------------------------------------
    The National Institute of Hygiene and Epidemiology is studying the
    genes of H1N1 virus from 2 patients following suspicion about its
    resistance to the antiviral drug oseltamivir or Tamilflu. The 2
    patients were among the 19 people admitted to the institute so far,
    Director Nguyen Van Kinh said Wednesday [8 Jul 2009]. 3 of these
    cases were locally transmitted, he added.

    The Health Ministry reported Wednesday [8 Jul 2009] 11 new influenza
    A (H1N1) patients -- 7 in the south, one in the central and 3 in the
    northern region -- raising the country's tally to 259. Of these, 186
    patients have been discharged from hospitals after full recovery.

    The ministry also said they are closely monitoring treatment
    resistance. The ministry will allow more hospitals to announce
    official test results instead of having to wait for the results of
    another test by authorized agencies. This would avoid waste of time
    and reduce the government's expenditure on testing, which comes to
    about USD 150 per case, the ministry said.

    The Department of Health in Thua Thien-Hue Province, said Wednesday
    [8 Jul 2009] they had instructed districts to set up facilities to
    quarantine those suspected of carrying the virus and treating
    confirmed H1N1 patients.

    Nguyen Dung, the department director, said the facilities at the
    districts would meet all criteria issued by the Health Ministry, and
    help ease overload in the provincial level hospitals. This will also
    prevent possible spread of the flu while transporting the patients, he added.

    The World Health Organization (WHO) Wednesday [8 Jul 2009] said some
    137 countries and territories have reported more than 98 000 cases
    including more than 440 deaths.

    WHO has been informed by health authorities in Denmark, Japan and the
    Special Administrative Region of Hong Kong, China of the appearance
    of H1N1 viruses which are resistant to Tamiflu based on laboratory testing.

    [5] Viet Nam - patient data
    Date: Wed 8 Jul 2009
    From: Rogier van Doorn <hrogier@gmail.com>


    In the Hospital for Tropical Diseases in Ho Chi Minh City, Viet Nam,
    patients with flu symptoms and a positive RT-PCR result for pandemic
    Influenza A (H1N1) 2009 virus infection with the CDC assay (specific
    A(H1N1)v primers/probe) are hospitalized and treated with oseltamivir
    (75mg bd) until RT-PCR results are negative.

    We collected clinical data, haematology and biochemistry, and daily
    virological data (nose and throat swabs) from the 1st 44 Influenza A
    (H1N1)v RT-PCR positive patients in Viet Nam hospitalized between 29
    May and 26 June 2009. The average age of the patients was 28.6 years
    (3-62), 19 female and 25 male
    . 5 patients contracted flu while in
    Viet Nam but with a clear epidemiological link to someone with
    "imported" H1N1, 39 cases were thought to be directly imported (14
    US, 18 Australia, 2 Canada, 2 Thailand, 1 Japan, 1 China, and 1 Singapore).

    Fever was present in 91 percent (n - 40), cough in 55 percent (n -
    24), runny nose in 20 percent (n - 9), sore throat in 27 percent (n -
    12), and diarrhea in 2 percent (n - 1). Average duration of fever on
    presentation was 2 days. After 24 hours 75 percent (n - 33) of
    patients had a normal temperature. All patients had a mild illness course.

    Viral PCRs were positive on day 0 for all patients with an average Ct
    value of 30.3. The number of PCR positive patients dropped to 25
    after 1 day (average Ct 30.3). On day 2, 21 patients were positive
    (average Ct 35.8) and on day 3 and 4, 8 patients were still PCR
    positive (average Ct 37.0 and 37.2). No patients were positive on day
    5, 6 and 7.

    These data suggest that patients treated with oseltamivir have a
    favourable clinical and virological response and are not shedding
    viral RNA after 5 days of treatment. In comparison, Whitley et al
    [Pediatr Infect Dis J 2001 20:127] found 55 percent (n - 51/93)
    culture positive patients in oseltamivir treated children with
    non-severe influenza on day 4.

    There have been a few anecdotal reports from Viet Nam of patients
    that remained symptomatic and PCR positive for a prolonged period,
    and one patient in our hospital (not included in this report) had a
    positive PCR after 18 doses of oseltamivir
    . Investigations into the
    presence of the NA H274Y mutation in [virus isolated from] these
    patients are ongoing but have so far been negative.

    The strain of influenza A (H1N1) resistant to Tamiflu was 1st
    detected in Denmark, and followed by Japan, United States, Hong Kong
    SAR (see prior PRO/MBDS postings listed below) and Viet Nam.

    According to the latest figures on confirmed cases of influenza A
    (H1N1) infection in neighboring countries of the MBDS region, there
    are 18 cases in Bangladesh, 1055 in Hong Kong SAR, 68 in Macau SAR,
    61 in Taiwan, 52 in Indonesia, 158 in India, 2033 in Japan, 513 in
    Malaysia, 1217 in Singapore, 19 in Sri Lanka, 333 in South Korea, and
    1709 cases and one death in Philippines.

    Update 58 of laboratory-confirmed cases of the new influenza A (H1N1)
    as officially reported to WHO by states parties to the international
    health regulations (2005), dated 6 Jul 2009, is available at
