Alot of helpful information has come out over the last few days.
Let's start with the 'Governor's Reports'. I suspect these are not one time documents, I would expect they are produced on some cadence. But the one for July 14th was put in a public space. If you want to see what they are you can go to the link here.

This is the report that has 18 states in the red zone (which basically agrees with non-governmental sources as well). it has charts, it also has recommendations of what you should do depending upon what zone your state and locality is in. GA is one of the 18 states in the red zone according to the Federal Government. It lists 30 metro areas (CBSA's) and 94 counties in GA in a red zone and an additional 9 CBSA's and 44 counties in a yellow zone. You are welcome to look at the document itself if you want to see the recommendations for governments and the public to take when they are in a red or yellow zone.
The information in that report mirrors what is in this website which I found out about because a doctor said it was one of the sites they were going to. Right now it is missing the hospitalization data it used to have, hopefully they will be able to get that back up and running soon. But some great data in here. It currently has 19 states as of today being in an 'uncontrolled spread' state and 18 states as 'trending poorly'.

This is still my favorite model, has been the most accurate one to this point.
We use artificial intelligence to accurately forecast infections, deaths, and recovery timelines of the COVID-19 / coronavirus pandemic in the US and globally

Interesting notes in this model Right now it estimates roughly 90K more people are being infected each day in the US now than in late March- a 38% increase from the previous high. It also estimates that the total number of US citizens infected with the virus right now is about 1.2M more than in Late March a 34% increase from that high. it currently projects that infections will continue to rise through the end of July and the deaths will continue to rise through late August.
This study from MIT on world infection and deaths is worth looking at. It use data from 84 countries to determine infections and deaths worldwide. It suggests that infections worldwide are 11.48X higher than the official counts and deaths are 48% higher than official counts. It provides estimated infection mortality rates and seroprevalence rates for the countries (for the US that is 0.99% and 5.3%). It also says unequivically that herd immunity will not work.

Effective responses to the COVID-19 pandemic require integrating behavioral factors such as risk-driven contact reduction, improved treatment, and adherence fat

If you are interested in an easy explanation of why herd immunity will not work I recommend going to MS Gov Tate Reeves Twitter page as he lays out exactly why it will not work and why we all need to work together.
There are been multiple studies released in the last week, one from Switzerland, one from South Korea that suggest kids under 10 do not transmit the virus to a large degree, but that kids 10-19 transmit the virus at basically the same rates as adults. This has obvious implications for school openings and how to proceed with them.
I think Dr. Redfield made a good statement last week, He said the majority of counties should be able to re-open schools. I think that is 100% correct. But whether he chose to leave this out purposely or not, what he did not say is that the majority of kids probably won't be able to go back to school yet. As the majority of students are concentrated in a minority of counties. For alot of kids we will likely have to wait to have them in schools until we get transmission rates down and then we can start bringing kids back, likely starting with elementary schools and then going up from there. I think the model Chicago has come up with has some promise. But we likely have to bring the transmission rate down significantly in this country before we are able to get the majority of students back in school buildings, the American Academy of Pediatrics released a letter on this topic
The head of Israel's Coronavirus Response team resigned recently, saying the government after doing a great job early on did a poor job in re-opening and that has caused a huge surge in Israel forcing them to create new restrictions. In her 8 page letter she mentions that the largest vectors in spread in Israel were caused by schools and weddings.
Siegal Sadetzki said Tuesday that Israeli leaders ignored her warnings and the country reopened too fast. "The compass handling the pandemic lost its direction," she said in her resignation letter.

There was a excellent article this weekend talking to epidimeologists as they continue to study and learn about this virus. One thing they are finding is that spreading is not consistent and routine like some viruses, it is very idiosyncratic. They are coming to the conclusion that the spreading is occurring primarily through a subset of 'super-emitters' that infect large numbers of people in a short period of time. The belief is that these people have much higher viral loads and are contagious for longer periods of time than others. The good news is this could be an achilles heel for the virus, the bad news is that at this point they don't have a way to identify them before the spread occurs. but as they go through contact tracing they are finding that the 'super emitters' are very similar to Typhoid Mary. In general they are finding a significant number of the 'super emitters' to be young, social and asymptomatic (or presymptomatic). That makes testing and finding asymptomatic individuals very important as they may need to be quarantined even more than those who have symptoms (who therefore tend to be more self-isolating and others can tell they are sick and avoid them). Most of the superspreader events that have been traced have been traced to events in social venues with large number of people - concerts, sports games, weddings, funerals, churches, rallies, restaurants and bars.
If we could find a way to isolate the super-emitters (or if everyone wears masks), you can largely stop the virus before it spreads.
In other COVID news. The Bahammas are going to start banning Americans on Wednesday as they start to see a rise in cases in their islands. Both Canada and Mexico are keeping the borders to the US closed to non-essential traffic through August. The countries that are allowing Americans to visit, currently about 20 worldwide, most of them require any American visitor to present a negative test result from within 48-72 hours before arrival into the country.
We are also seeing are testing processes breakdown again with long waits for results that make them useless from a diagnostic control purpose and shortages of testing supplies. This makes it more difficult to get any sort of control of the virus in the US. It looks like cases in AZ may have peaked, but that potentially also could be a function of a broken testing system where tests are not being taken and the ones that are have a long delay in reporting, we just don't know.
Morehouse, Spelman and Clark Atlanta all announced today that they are switching from their previous plans and going to a fully online fall semster.
I'll end with this, an article talking about Dr. Redfield's comments that if we all wore masks we could get this under control in 4-8 weeks.
The article mentions a couple of studies. One looks at masking policies in 194 countries. Countries that recommended wearing masks saw an 8% increase in weekly per capita mortality rates, those that did not recommend wearing masks had a 54% increase. The article also mentions the linked JAMA study on mask wearing at the largest health care system in MA and how wearing masks greatly reversed an exponential increase in infections.
"If we could get everybody to wear a mask right now, I really think in the next four, six, eight weeks, we could bring this epidemic under control," the CDC director said.

This study describes SARS-CoV-2 PCR test positivity among health care workers before, during, and after implementation of a policy requiring universal masking of all health care workers and patients in a large health care system in Massachusetts.
