Our results indicate that aerosol and fomite transmission of HCoV-19 are plausible, as the virus can remain viable and infectious in aerosols for multiple hours and on surfaces up to days.
The findings and conclusions in this letter are those of the authors and do not necessarily represent the official position of the Centers for Disease Control and Prevention (CDC).
We have a simple message for all countries: test, test, test.
Test every suspected case.
If they test positive, isolate them and find out who they have been in close contact with up to 2 days before they developed symptoms, and test those people too. [NOTE: WHO recommends testing contacts of confirmed cases only if they show symptoms of COVID-19]
People infected with COVID-19 can still infect others after they stop feeling sick, so these measures should continue for at least two weeks after symptoms disappear.
Visitors should not be allowed until the end of this period.
Health-care professionals have been working day and night since Feb 20, and in doing so around 20% (n=350) of them have become infected, and some have died.
In Italy, we have approximately 5200 beds in intensive care units. Of those, as of March 11, 1028 are already devoted to patients with SARS-CoV-2 infection, and in the near future this number will progressively increase to the point that thousands of beds will soon be occupied by patients with COVID-19. Given that the mortality of patients who are critically ill with SARS-CoV-2 pneumonia is high and that the survival time of non-survivors is 1–2 weeks, the number of people infected in Italy will probably impose a major strain on critical care facilities in our hospitals, some of which do not have adequate resources or staff to deal with this emergency. In the Lombardy region, despite extraordinary efforts to restrict the movement of people at the expense of the Italian economy, we are dealing with an even greater fear—that the number of patients who present to the emergency room will become much greater than the system can cope with. The number of intensive care beds necessary to give the maximum number of patients the chance to be treated will reach several thousand, but the exact number is still a matter of discussion among experts. Health-care professionals have been working day and night since Feb 20, and in doing so around 20% (n=350) of them have become infected, and some have died.Lombardy is responding to the lack of beds for patients with COVID-19 by sending patients who need intensive care but are not infected with COVID-19 to hospitals outside of the region to contain the virus.
実はこの一つ前のパラグラフでもICU＝Intensive care unit＝集中治療室における状況について語っているので、どうやら "20% (n=350)" という部分は【集中治療室に関わる医療従事者で感染した者の数】を表しているようです。 （パラグラフが "In Italy" で始まっているため注意を要するが、ロンバルディア州のベルガモ大学の教授の論文であることや前後の文はロンバルディア州に関することがらなので、ロンバルディア州に関するものである可能性が高い。）
ランセット論文では"In Italy, we have approximately 5200 beds in intensive care units. Of those, as of March 11, 1028 are already devoted to patients with SARS-CoV-2 infection,"とあるように、イタリア全土で５２００のＩＣＵベッドがある中、１０２８床が新型コロナウイルスのために稼働状態とのことですが、これに対して３５０人の医療従事者しかいないというのは日本のＩＣＵの運用方針からは到底考えられません。
