CDC has been way behind on their info. They seem more worried about stopping "stigma" than stopping the spread. According to the page you linked to, you are not to call them, even if you have all the symptoms, unless you have been in close contact with someone who has the disease, or you visited an area with "ongoing spread". So, I guess that means that if the clerk at McDonalds, or the cashier at Walmart, develops symptoms, they shouldn't bother calling because they aren't going to get tested. Apparently they need to get to the stage where they require hospitalization before they can be tested. Now, I suppose that if you consider the entire US to be areas of "ongoing spread", then they could be tested if they have symptoms.
I presume the reason the web site says this is because they didn't have the testing capacity to test very many people. Supposedly this week that will change.
Yes, the identifying traits of an established infection are a cough and a fever. Earlier, however, most people experience rhinitis, followed by an asymptiomatic stage where they are contagious that can last 4-9 days. You saw examples of that on the Diamond Princess. Some people said something along the lines of "I thought I had gotten a cold, and gotten over it quickly. When I tested positive, I couldn't believe it."
CDC does mention that it is possible that asymptiomatic spread is happening, but doesn't think it is a significant driver in the spread, and that we should focus on people with symptoms. That doesn't really match up with experiences in other countries, however. In China, they were able to control SARS, which didn't spread until you had symptoms, by quickly identifying and quarantining people with symptoms. That didn't work with COVID19, so they quarantined everyone. Here's an article on the subject in the US:
https://www.cnn.com/2020/03/14/health/coronavirus-asympto... South Korea has been very successful in controlling it because they made the tests fast and free, and available to anyone. If someone has symptoms, they can get tested without having to prove they were in contact with someone who had it. If someone was in contact with someone who had it, they can get tested without symptoms. The result has been a tremendous number of negative tests, but also has been to catch a lot of cases very early, dramatically reducing the spread. [/QUOTE]

Another article showing disagreement with CDC's statement that "Some spread might be possible before people show symptoms; there have been reports of this occurring with this new coronavirus, but this is not thought to be the main way the virus spreads".
[QUOTE=allen] The false flag stories should come to an end at this point, no my uncle bubba went to work with a cold and a fever. If you are sick stay home. This virus is very infectious, the White House officially ended their this is just a flu campaign and they have experts like Dr. Fauci, please don’t give your opinions unless you are an epidemiologist. Stay safe Bobcats
