I realize that without further details made public we're left picking up scraps of info about the White House cluster, but putting together a list of people and their test results and speculating about their exposures is not "contact tracing".
Contact tracing is supposed to be a methodical effort by investigators to speak with known cases, ensuring they have support and are taking proper precautions, and also ask them about their close contacts so those people can be told they have been exposed and take proper action.
Contact tracers:
-Let people know they may have been exposed and should monitor their health for signs and symptoms of the disease.
-Help people who may have been exposed get tested.
-Ask people to self-isolate if they have the disease or self-quarantine if a close contact.
There are likely many people beyond senior White House officials and high-profile politicians who have been exposed, such as family members, staff, media. Those of us looking in from afar are not in a position to do an actual contact tracing investigation on all these people.
It is another question entirely whether there is or will be a robust contact tracing investigation of the White House cluster. By all accounts, one has yet to be initiated. But, investigation by media report is poor substitute for actual contact tracing.

ICYMI: @KFF released the results of a new poll a few days ago, covering a number of #COVID19 topics.

I'll highlight a few of the findings in a thread.

kff.org/coronavirus-co…
Among all registered voters the economy ranks as the most important voting issue, the coronavirus pandemic next. However, there is a stark difference by party, with 36% of Dems saying coronavirus is most important and just 4% of Republicans saying that. Image
If a Covid-19 vaccine became available before the election, just 4 in 10 said they would choose to get vaccinated (with Republicans slightly more likely to say no than Democrats). Image

Contact tracing apps have evolved to become "exposure notification apps"; Apple and Google are streamlining the process of participation, allowing push notifications for users to opt-in automatically (Apple) or direct users to state-supported notification apps (Google).
The hope is that there will be much greater adoption of these apps because now opt-in will be embedded directly in device operating systems.

Adoption is state-by-state, and about 20 states have, or will soon be, deploying this approach.
Up until now, uptake of state contact tracing apps has been quite low. For example, "less than 5% of the population in North Dakota downloaded the state’s app as of June, while only about 1.8% of Utahns had done so by July."

I’ve been thinking about the only other time a pandemic vaccine was rolled out during a US Presidential election year: the 1976 “swine flu” campaign. What warnings and lessons might that experience hold?
In brief, a new influenza virus was detected in January 1976 in NJ. Public health officials at the time thought the US (and the world) faced an imminent pandemic from this virus, to which no one under 50 had pre-existing immunity.
In March President Ford, following strong recommendations from CDC experts and other health officials, announced the US would develop and distribute enough vaccines to immunize every man, woman, and child in the country to prevent a pandemic.

It is increasingly clear that Chinese government officials- locally in Wuhan and nationally in Beijing- sought to hide information and downplay the seriousness of the coronavirus outbreak in the critical first weeks of the pandemic.
nytimes.com/2020/08/19/wor…
Wuhan officials hid information from national authorities. A recent U.S. intelligence community assessment concluded "Officials in Beijing were kept in the dark for weeks about the potential devastation of the virus by local officials in central China."
At the same time "senior officials in Beijing, even as they were scrambling to pry data from officials in central China, played a role in obscuring the outbreak by withholding information from the World Health Organization."

A few weeks ago @ForeignAffairs asked a group of experts if they agreed or disagreed with the following statement (and level of confidence):

"The daily tally of COVID-19 cases around the world will be higher at the beginning of 2021 than it is today."

foreignaffairs.com/ask-the-expert…
Prediction is a fool's game, especially when it comes to pandemics, but even so a number of us responded. Most agreed with the statement, some with fairly high levels of confidence.
I disagreed with the statement (though with little confidence).

When we were asked to weigh in, the global average number of new cases was surpassing 200,000 daily. So I thought, how might that level compare to the tally we will see in the first weeks of 2021?

There continues to be a divide among health experts about kids, schools, and coronavirus. Here are a few articles published just in the last few days looking at the evidence and coming to different conclusions.

1) "Kids Aren't Viral Vectors. Really."
nytimes.com/2020/08/12/opi…
2) "COVID-19, children, and schools: overlooked and at risk"

"Seroprevalence and contact tracing studies show children are similarly vulnerable [to adults] and transmit the virus to a meaningful degree"
mja.com.au/journal/2020/c…
3) "Latest research points to children carrying, transmitting coronavirus"
"Are they susceptible to catching the virus? Absolutely. Are they able to transmit the virus? Absolutely"
