Whoops, I checked the wrong preprint server. A simple google search found the paper at medRxiv and a few other preprint servers. Of course, it may undergo further editing before publication. I don’t have time to read it right now.

Sorry I didn’t do this earlier.

Here’s a link:

As I’ve said in both of my previous comments, the paper hasn’t yet been published. The web page for the journal issue that will include the paper provides a citation, but nothing more.

Or maybe you’ve looked at preprint servers and didn’t find it? Is that what you mean? I checked bioRxiv, but it wan’t there.

Anyway, I’d expect the paper to be available soon. It looks as if about half of the papers from the June issue have been published. For the time being, I’m forced to rely on the MedicalXpress report describing the paper. My first comment linked to that report — the one you accurately called a press release.

I understand your preference for the original paper, but it’s just not available yet. When it becomes available, we now know where it will appear, if you care to read it at a later date.

Article not found.

Found at the web site for the journal “Emerging Infectious Diseases.”

The paper itself has not yet been published.

I searched for the text of that research you mention but I could not find it. Unless I can read the actual report rather than a press release about it, I have no way to understand how they came to their conclusion about asymptomatic transmission. But from that press release, I find it hard to see how the researchers could know that it was an asymptomatic exposure rather than passing by someone sneezing in the street, for example. Here, that latter scenario would be highly unlikely, because so few people are infected at this point. But in China, it was a lot more prevalent.

This one is a study abstract, and you have to speak med-talk to understand it.

That’s a link to a report describing a paper soon to be published in the journal “Emerging Infectious Diseases.”

Among other things, the paper addresses the the issue of pre-symptomatic patients spreading the Wuhan coronovirus infection.

The authors found that more than one in ten transmissions were by patients without symptoms. I don’t know whether I should feel encouraged or discouraged by that number. This is just one paper; but, for what it’s worth, here’s a paragraph describing its contents:

“Meyers and her team examined more than 450 infection case reports from 93 cities in China and found the strongest evidence yet that people without symptoms must be transmitting the virus, known as pre-symptomatic transmission. According to the paper, more than 1 in 10 infections were from people who had the virus but did not yet feel sick.

Previously, researchers had some uncertainty about asymptomatic transmission with the coronavirus. This new evidence could provide guidance to public health officials on how to contain the spread of the disease.”

It contains the same time series data as mine so I’ve decided to make this the first and last day that I update my site.

Each day I’ll visit JHU’s GitHub repository and download the time series data for USA Confirmed Cases, Deaths, and Recoveries. I’ll import it into Excel and build Pivot Tables and Charts, then take a screenshot and upload it to my site.

Ideally I would import just the time series data to my website and then let you visualize it with charting software. One step at a time.
