1/27有2名武漢肺炎患者在英國被診斷。2名患者都是在社區中被發現，直接由他們所在的旅館送至當地Hull大學教學醫院的感染科，安置在隔離病房等待檢驗結果，確診之後，即被轉送至Newcastle的High-Consequence Infectious Diseases (HCID) Unit。決定是否檢測SARS-CoV-2有一定的流程，然若這兩名個案嚴格遵照此流程，將不被受檢。通常檢查需有明確的個案定義；但面對新興傳染病，個案定義須隨著資訊盡速應變。此外，在此類病例確診前，這些病例是在沒有中央經費或專門單位的當地醫院作處置，有可能增加院內傳染的風險。地方上之HCID unit應提高層級已降低院內感染風險。

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the cause of an ongoing international outbreak of respiratory illness, known as coronavirus disease 2019 (COVID-19).1, 2, 3 In the week commencing Jan 27, 2020, the first two cases were diagnosed in England. Both patients were identified as being at risk while still in the community, and transported directly from their hotel to the regional Infectious Disease Unit at Hull University Teaching Hospitals.
The patients were met on arrival by medical and nursing staff using enhanced personal protective equipment, in accordance with national guidance. They were placed in separate negative pressure rooms with antechambers, and managed there until the results of tests were available. Once both patients were confirmed to have SARS-CoV-2, they were transferred to the designated High-Consequence Infectious Diseases (HCID) Unit in Newcastle, UK.
These first UK cases of COVID-19 raise important points about the management of cases of HCID in England. The decision to test for SARS-CoV-2 is based on a clinical and epidemiological case definition, and testing is only approved if this is met. When tested, neither of these people clearly met the current case definition, and had criteria been strictly applied, testing might not have been done. A decision to test was made because of high clinical suspicion and in response to latest available information about the distribution of infection. It is important that testing is appropriately targeted, and this is best done by applying clear case definitions. However, with any newly emerging infection, case definitions must evolve rapidly as information accrues. There should also be room for flexibility on the basis of discussion with clinical and public health experts.
These patients were identified in the community and were transferred directly to a specialist isolation facility for assessment. Once the diagnosis was confirmed, the patients were moved to one of the HCID Units commissioned by National Health Service (NHS) England. These units are funded centrally and have to comply with a national specification for the management of confirmed HCID. However, the management and assessment of possible cases of HCID (when the risk of nosocomial transmission may be higher, as has been shown elsewhere in the current outbreak, and in other cases of HCID in England4) remains locally commissioned, with no central funding or specification. There is little incentive for acute NHS Trusts or Clinical Commissioning Groups to commission isolation facilities, or to maintain a pool of trained staff, as funding mechanisms are unlikely to cover the significant investment required. Although many areas (as in this case) do have effective local arrangements based on locally commissioned isolation facilities, there are other parts of the country where there are no such facilities and expertise in managing highly transmissible infections is limited. The HCID Units should be supported by a second tier of appropriately commissioned regional facilities so that high-risk suspected cases can be assessed safely and risk of nosocomial transmission minimised.
