Wow. So she was spreading it around for WEEKS and only tested because she was in critical condition. So how many have mild flu and cold symptoms who never get tested? I have a feeling this is way way more widespread than recognized. Japanese taxi driver who can recall only driving one person who appeared to be Chinese?
I'm glad that the WHO briefing addressed this question today as it's something I have been wondering about, too.
This is from dixiegirl's post above:
re iceberg analysis, how big is the iceberg? A. In the absence of serology testing in ER's they have been testing thousands of samples and at the moment we are not seeing COVID in samples in Singapore and China. It's speculation, but therefore we think we are knowing of where cases are and it's not so more widespread. If we look outside China, over 400 cases and 4-5 weeks... only 22% evolved from local transmission. All of those cases, only 8 are not linked to our identified chains. Without serology test, we cannot say without absolute certainty how wide in communities.
So this is good news to me that they've been doing these random tests in patients who have presented with respiratory problems but not really suspected of Covid-19.
We obviously don't know if it's going to stay this way, but it's a good sign for the present.
