如何看待美國武肺檢測數連續五日大幅下降?

https://www.cdc.gov/coronavirus/2019-ncov/testing-in-us.html



CDC統計數據顯示,從3月6日開始到3月10日,CDC實驗室與其他公衛實驗室有關武漢肺炎檢測數大幅下降(3,4兩日曾大幅上漲):

注:3月7-10日數據待統計(Data during this period are pending.)

Pence因此被CNN記者質問,顧左右而言他

補充材料:
1. CDC和NIAID的主任在周四的聽證會上都承認公衛實驗室無法進行快速及大劑量的檢測

The CDC has the capacity to process between 300 and 350 tests a day, Redfield said. He said other systems that can process thousands of specimens are coming online with private labs LabCorp and Quest. Public health labs just aren’t set up to process a high volume of tests quickly, Redfield and Fauci both testified.

2. 截至3月9日下午四點,下文只查證到4384人接受過檢查,當時確診數為570

3. 据科學雜誌與Linoj Samuel的訪談(who heads the clinical microbiology division that oversees lab testing for the Henry Ford Health System in Detroit, spoke with Science about the situation he’s facing. Henry Ford has six hospitals and many medical centers that cover most of southeast Michigan. ),在CDC放寬檢測標準之前,他們只向州立實驗室提交過幾個樣本,放寬之後也差不多:
Q: Do you know how many samples you sent to the state lab prior to them relaxing the criteria?
A: Not many. It was probably in the single digits.
Q: Do you know how many you've sent since they've relaxed it?
A: That just happened in the last 2 days. So we've probably sent maybe four or five samples.

訪談中Linoj Samuel也抱怨CDC的檢測標準太嚴格,阻礙了檢測進度

4. 在周四的聽證會之後,多位參議員對檢測裝備短缺和現有數據是否能反映真實感染人數表達了憂慮

5. 上周一,Pence及FDA委員表示到周末可為一百萬人進行檢測,但很快又承認這個目標只能在下周末達到
https://www.bbc.com/news/world-us-canada-51761435
At a press briefing on Monday, Food and Drug Administration Commissioner Stephan Hahn said close to a million tests would be ready by the end of this week.

But Vice-President Pence - who is coordinating the US response to the outbreak - conceded on Thursday that that target would not be met.

"We don't have enough tests today to meet what we anticipate will be the demand going forward," Mr Pence said during a visit to a factory in Minnesota.

But he said that by the end of next week the US government's diagnostic supplier would distribute kits across the country that would enable 1.2 million Americans to be tested for coronavirus.
出埃及记 文明是有季候的
发表发全啊,图里三月六号到三月十号都有灰色标记和双十字符号,官网下面对双十字符号附了一句“Data during this period are pending”的注释,我想大概是cdc从6号开始就不再对全国的测试数进行详细统计了,让各州自己去统计和公布。你看他10号后连数据都没了
因为检测现在下放到社区了,是用韩国那种drivethru检测,所以不在统计检测数目,只统计确诊数目。实际检测数目在百万级别。

上周彭斯就说了,你们都不听课的吗?

下放到地方了,cdc直接躺尸了,现在地方积极的就多测点像纽约,死不动弹的就像洛杉矶还没测够八十例。
