鳥インフルエンザH5N1の人への感染がミャンマーで確認

これまで、鳥インフルエンザH5N1亜型の感染例がなかったミャンマーで、感染が確認されたことが、WHOから12月14日付けでアナウンスされています。患者は回復したようです。これでアジアを中心に13ヶ国で発生が確認されたことになります。

また、同じくWHOから15日付でパキスタンでH5N1の感染が疑われる事例が報告されています。こちらはまだ確定されていませんが、確定されればパキスタンもヒトへの感染は初めてになります。

ミャンマーもパキスタンもトリからヒトへの感染が疑われています。
少し心配な情報です。

Avian influenza - situation in Myanmar
The Ministry of Health in Myanmar has confirmed the country's first case of human infection with the H5N1 avian influenza virus. The case is a 7-year-old female from Kyaing Tone Township, Shan State (East).
The case was detected through routine surveillance following an outbreak of H5N1 in poultry in the area in mid-November. She developed symptoms of fever and headache on 21 November 2007 and was hospitalized on 27 November. She has now recovered. Samples taken from the case tested positive for H5N1 at the National Health Laboratory in Yangon, and the National Institute of Health in Thailand. The diagnosis was further confirmed at the WHO Collaborating Centre for Reference and Research on Influenza, National Institute of Infectious Diseases in Tokyo, Japan.
A team from the Ministry of Health, the Ministry of Livestock and Fisheries and the WHO Country Office are conducting investigations to confirm the source of her infection. Initial findings indicate poultry die off in the vicinity of the case's home in the week prior to the onset of illness. To date, all identified contacts of the case remain healthy and ongoing surveillance activities in the area have not detected any further cases.

Avian influenza - situation in Pakistan
The Ministry of Health in Pakistan has informed WHO of 8 suspected human cases of H5N1 avian influenza infection in the Peshawar area of the country. These cases were detected following a series of culling operations in response to outbreaks of H5N1 in poultry. One of the cases has now recovered and a further two suspected cases have since died.
Samples taken from the suspected cases have tested positive for H5N1 in the national laboratory and are being forwarded to a WHO H5 Reference Laboratory for confirmation and further analysis. The MoH is taking steps to investigate and contain this event, including case isolation and contact tracing and monitoring, detailed epidemiological investigations, providing oseltamivir for case management and prophylaxis, reviewing hospital infection control measures and enhancing health care-based and community-based surveillance for acute respiratory infections.
WHO is providing technical support to the MoH in epidemiological investigations, reviewing the surveillance, prevention and control measures that have been implemented and carrying out viral sequencing of avian and human isolates.
Multiple poultry outbreaks of H5N1 influenza have been occurring in Pakistan since 2006. In 2007, there have also been outbreaks in wild birds. A majority of the outbreaks discovered have been in the ‘poultry belt’ of North-West Frontier Province, particularly in the Abbottabad and Mansehra area and cases of infection in wild birds have been identified in the Islamabad Capital Territory.
