新たなSARSウイルス類似の呼吸器疾患
 2002年に世界的流行となり何百人もの死者が出たSARSウイルスに似たコロナウイルスに感染した49歳男性がカタールからロンドンに移送された。2番目に確認された患者で、最初の患者はサウジアラビアの患者で死亡している。
 WHOは現時点では旅行制限を推奨していない。

New 'Sars-like' coronavirus identified by UK officials

画像A new respiratory illness similar to the Sars virus that spread globally in 2002 and killed hundreds of people has been identified in a man who is being treated in Britain.

The 49-year-old man, who was transferred to a London hospital by air ambulance from Qatar, is the second person confirmed with the coronavirus.

The first case was a patient in Saudi Arabia who has since died.

Officials are still determining what threat the new virus may pose.

The World Health Organization has not recommended any travel restrictions.

Prof John Watson, head of the respiratory diseases department at the UK's Health Protection Agency, said: "In the light of the severity of the illness that has been identified in the two confirmed cases, immediate steps have been taken to ensure that people who have been in contact with the UK case have not been infected, and there is no evidence to suggest that they have.

"Further information about these cases is being developed for healthcare workers in the UK, as well as advice to help maintain increased vigilance for this virus."

He said there was no specific evidence of the virus spreading from person to person and he had no advice for the public or returning travellers.

Peter Openshaw, director of the Centre for Respiratory Infection at Imperial College London, told Reuters that at this stage the novel virus looked unlikely to prove a concern, and may well only have been identified due to sophisticated testing techniques.

Coronaviruses are a large family of viruses which includes ones that cause the common cold and Sars (severe acute respiratory syndrome).

This new virus is different from any coronaviruses that have previously been identified in humans.

There have been a small number of other cases of serious respiratory illness in the Middle East in the past three months, one of whom was treated in the UK but has since died.

This person's illness is also being investigated, although there is no evidence as yet to suggest that it is caused by the same virus or linked to the current case. No other confirmed cases have been identified to date in the UK.

Sars is a serious respiratory infection that caused a global outbreak in 2002, spreading from Hong Kong to more than 30 different countries around the world and killing around 800 people. Although it has not been eradicated its spread was fully contained in 2003. Like other coronaviruses, it is spread through droplets of body fluids - produced by sneezing and coughing.

Novel Coronavirus infection in the United Kingdom

23 SEPTEMBER 2012 - On 22 September 2012, the United Kingdom (UK) informed WHO of a case of acute respiratory syndrome with renal failure with travel history to the Kingdom of Saudi Arabia (KSA) and Qatar.

The case is a previously healthy, 49 year old male Qatari national that presented with symptoms on 3 September 2012 with travel history to the KSA prior to onset of illness. On 7 September he was admitted to an intensive care unit (ICU) in Doha, Qatar. On 11 September, he was transferred to the UK by air ambulance from Qatar. The Health Protection Agency of the UK (HPA) conducted laboratory testing and has confirmed the presence of a novel coronavirus .

The HPA has compared the sequencing of the virus isolate from the 49 year old Qatari national with that of a virus sequenced previously by the Erasmus University Medical Centre, Netherlands. This latter isolate was obtained from lung tissue of a fatal case earlier this year in a 60 year-old Saudi national. This comparison indicated 99.5% identity, with one nucleotide mismatch over the regions compared.

Coronaviruses are a large family of viruses which includes viruses that cause the common cold and SARS. Given that this is a novel coronavirus, WHO is currently in the process of obtaining further information to determine the public health implications of these two confirmed cases.

With respect to these findings, WHO does not recommend any travel restrictions. Information regarding requirements and recommendations for the Hajj season in 2012 can be found at http://www.who.int/ith/updates/20120730/en/index.html
