Objective:
To evaluate the risk for transmission of SARS-CoV-2 to close contacts in different settings.
Design:
Prospective cohort study.
Setting:
Close contacts of persons infected with SARS-CoV-2 in Guangzhou, China.
Participants:
3410 close contacts of 391 index cases were traced between 13 January and 6 March 2020. Data on the setting of the exposure, reverse transcriptase polymerase chain reaction testing, and clinical characteristics of index and secondary cases were collected.
Measurement: Coronavirus disease 2019 (COVID-19) cases were confirmed by guidelines issued by China. Secondary attack rates in different settings were calculated.
Results:
Among 3410 close contacts, 127 (3.7% [95% CI, 3.1% to 4.4%]) were secondarily infected. Of these 127 persons, 8 (6.3% [CI, 2.1% to 10.5%]) were asymptomatic. Of the 119 symptomatic cases, 20 (16.8%) were defined as mild, 87 (73.1%) as moderate, and 12 (10.1%) as severe or critical. Compared with the household setting (10.3%), the secondary attack rate was lower for exposures in healthcare settings (1.0%; odds ratio [OR], 0.09 [CI, 0.04 to 0.20]) and on public transportation (0.1%; OR, 0.01 [CI, 0.00 to 0.08]). The secondary attack rate increased with the severity of index cases, from 0.3% (CI, 0.0 to 1.0%) for asymptomatic to 3.3% (CI, 1.8% to 4.8%) for mild, 5.6% (CI, 4.4% to 6.8%) for moderate, and 6.2% (CI, 3.2% to 9.1%) for severe or critical cases. Index cases with expectoration were associated with higher risk for secondary infection (13.6% vs. 3.0% for index cases without expectoration; OR, 4.81 [CI, 3.35 to 6.93]).
Limitation:
There was potential recall bias regarding symptom onset among patients with COVID-19, and the symptoms and severity of index cases were not assessed at the time of exposure to contacts.
Conclusion:
Household contact was the main setting for transmission of SARS-CoV-2, and the risk for transmission of SARS-CoV-2 among close contacts increased with the severity of index cases.
The Annals of Internal Medicine just published a comprehensive new study on how contagious the COVID-19 virus is. And I’m sorry to report that the case for a number of popular new practices that seem to have filled some spiritual need a lot of Americans have for self-abasement just completely collapsed.
The list of practices no longer having any conceivable rationale includes:
Closing down schools.
Closing down gyms, barber shops, or any other businesses.
Limiting the number of patrons allowed in restaurants or other businesses at one time.
Mass testing for the COVID-19 virus.
Putting healthy people in quarantine.
Keeping a distance of 3, 6, or some other arbitrary number of feet away from healthy individuals.
Healthy individuals with no criminal intent wearing masks when it’s not Halloween.
Likewise for any other humiliating rituals state and local officials plan on forcibly enacting to keep you safe from the scourge of COVID-19 that their own sense of self-worth precludes participating in.
When someone says (like Ari Fleischer) they're a bunch of wackadoodles, I'm going to reply with this question: Like Congress?

All the opposition sees is the negative content. They use it against people like us. They paint us with a broad brush in the worst ways.
The 1st Amendment is a great thing, but it's a double-edged sword.

At today's speech, Trump talked about the mail in voting fiasco and how chaotic it's going to be. He even mentioned something I brought up here as a possibility...Nancy Pelosi could become acting president in January due to the inability to make a final determination as to the clear winner of the election.
So, yes, we need to vote like our lives depend on it. But, the Dems are pulling trying desperately to pull out the Big Cheat.

So much info and so many meanings from one picture!
Re Nancy Pelosi being C_A, this would absolutely make sense if all prior presidents back to GHW Bush were C_A. Wouldn't deep state also make sure the VPs and Speakers were CIA so they always had the next in line available and the ability to remove the incumbent POTUS - ultimate control.
The 1970s came to be known as the “time of troubles” for the CIA. Six different DCIs served within a ten-year timeframe. The Agency was shrouded in controversy from the leak of the “Family Jewels,” an internal report detailing controversial activities undertaken by the Agency dating back to President Dwight Eisenhower’s administration.
Congressional committees led by Representative Otis Pike and Senator Frank Church were formed in early 1975 to determine “the extent, if any, to which illegal, improper, or unethical activities were engaged in by any agency of the Federal Government.” The leak of the Family Jewels coupled with the investigations tainted the public image of the CIA and plummeted the morale of Agency officers.
.....Employees at the Silicon Valley company are laying out contingency plans and walking through postelection scenarios that include attempts by Mr. Trump or his campaign to use the platform to delegitimize the results, people with knowledge of Facebook’s plans said.
Facebook is preparing steps to take should Mr. Trump wrongly claim on the site that he won another four-year term, said the people, who spoke on the condition of anonymity. Facebook is also working through how it might act if Mr. Trump tries to invalidate the results by declaring that the Postal Service lost mail-in ballots or that other groups meddled with the vote, the people said......
Mark Zuckerberg, Facebook’s chief executive, and some of his lieutenants have started holding daily meetings about minimizing how the platform can be used to dispute the election, the people said. They have discussed a “kill switch” to shut off political advertising after Election Day since the ads, which Facebook does not police for truthfulness, could be used to spread misinformation, the people said........
