We all have varying opinions about the impact of this, the numbers, etc. We will all never agree with each other. But we can all keep it civil.
Thanks!

California coronavirus case could be first spread within U.S. community, CDC says

The Centers for Disease Control and Prevention is investigating what could be the first case of novel coronavirus in the United States involving a patient in California who neither recently traveled out of the country nor was in contact with someone who did.
“At this time, the patient’s exposure is unknown. It’s possible this could be an instance of community spread of COVID-19, which would be the first time this has happened in the United States,” the CDC said in a statement. “Community spread means spread of an illness for which the source of infection is unknown. It’s also possible, however, that the patient may have been exposed to a returned traveler who was infected.”
The individual is a resident of Solano County and is receiving medical care in Sacramento County, according to the state Department of Public Health.
The CDC said the “case was detected through the U.S. public health system — picked up by astute clinicians.”
Officials at UC Davis Medical Center expanded on what the federal agency might have meant by that in an email sent Wednesday, as reported by the Davis Enterprise newspaper.
The patient arrived at UC Davis Medical Center from another hospital Feb. 19 and “had already been intubated, was on a ventilator, and given droplet protection orders because of an undiagnosed and suspected viral condition,” according to an email sent by UC Davis officials that was obtained by the Davis Enterprise.
The staff at UC Davis requested COVID-19 testing by the CDC, but because the patient didn’t fit the CDC’s existing criteria for the virus, a test wasn’t immediately administered, according to the email. The CDC then ordered the test Sunday, and results were announced Wednesday. Hospital administrators reportedly said in the email that despite these issues, there has been minimal exposure at the hospital because of safety protocols they have in place.
A UC Davis Health spokesperson declined Wednesday evening to share the email with The Times.
Since Feb. 2, more than 8,400 returning travelers from China have entered California, according to the state health department. They have been advised to self-quarantine for 14 days and limit interactions with others as much as possible, officials said.
“This is a new virus, and while we are still learning about it, there is a lot we already know,” Dr. Sonia Angell, director of the California Department of Public Health, said in a statement. “We have been anticipating the potential for such a case in the U.S., and given our close familial, social and business relationships with China, it is not unexpected that the first case in the U.S. would be in California.”
It is not clear how the person became infected, but public health workers could not identify any contacts with people who had traveled to China or other areas where the virus is widespread. That raises concern that the virus is spreading in the United States, creating a challenge for public health officials, experts say.
“It’s the first signal that we could be having silent transmission in the community,” said Lawrence Gostin, director of the World Health Organization Collaborating Center on National and Global Health Law. “It probably means there are many more cases out there, and it probably means this individual has infected others, and now it’s a race to try to find out who that person has infected.”
On Tuesday, the CDC offered its most serious warning to date that the United States should expect and prepare for the coronavirus to become a more widespread health issue.
“Ultimately, we expect we will see coronavirus spread in this country,” said Nancy Messonnier, director of the CDC’s National Center for Immunization and Respiratory Diseases. “It’s not so much a question of if, but a question of when.”
According to the CDC’s latest count Wednesday morning, 59 U.S. residents have tested positive for the new strain of coronavirus — 42 of whom are repatriated citizens from a Diamond Princess cruise. That number has grown by two since Messonnier’s last count Tuesday, although the CDC was not immediately available to offer details on the additional cases.
More than 82,000 cases of coronavirus have been reported globally, and more than 2,700 people have died, with the majority in mainland China, the epicenter of the outbreak.
But public health leaders have repeatedly reminded residents that the health risk from the novel coronavirus to the general public remains low.
“While COVID-19 has a high transmission rate, it has a low mortality rate,” the state Department of Public Health said in a statement Wednesday. “From the international data we have, of those who have tested positive for COVID-19, approximately 80% do not exhibit symptoms that would require hospitalization. There have been no confirmed deaths related to COVID-19 in the United States to date.”
CDC officials have also warned that although the virus is likely to spread in U.S. communities, the flu still poses a greater risk.
Gostin said the news of potential silent transmission does not eliminate the possibility of containing the virus in the U.S. and preventing an outbreak.
“There are few enough cases that we should at least try,” he said. “Most of us are not optimistic that that will be successful, but we’re still in the position to try.”
Highlights
• SARS-CoV-2 is highly susceptible to irradiation with ultraviolet light
• High viral loads of 5 *106 TCID50/ml SARS-CoV-2 can be inactivated in 9 minutes by UVC irradiation
• UVC irradiation represents a suitable disinfection method for SARS-CoV-2
Abstract
The coronavirus SARS-CoV-2 pandemic became a global health burden. We determined the susceptibility of SARS-CoV-2 to irradiation with ultraviolet light. The virus was highly susceptible to ultraviolet light. A viral stock with a high infectious titer of 5 × 106 TCID50/ml was completely inactivated by UVC irradiation after nine minutes of exposure. The UVC dose required for complete inactivation was 1048 mJ/cm2. UVA exposure demonstrated only a weak effect on virus inactivation over 15 minutes. Hence, inactivation of SARS-CoV-2 by UVC irradiation constitutes a reliable method for disinfection purposes in health care facilities and for preparing SARS-CoV-2 material for research purpose.
[...]
Discussion
In the present study, we demonstrated that SARS-CoV-2 could effectively be inactivated by UVC irradiation, even at high viral titers, whereas UVA-irradiation was much less effective. These data are in line with previous reports where other coronaviruses e.g. SARS-CoV-1 were shown to be susceptible to UVC irradiation 5, 6, 7. Viral stocks with titers of 1 × 106 TCID50/ml of SARS-CoV-1 could be almost completely inactivated after 6 minutes of UVC-irradiation, corresponding to a UVC dose of 1446 mJ/cm2 5. In our study, the emitted dose required for a complete inactivation of SARS-CoV-2 was 1048 mJ/cm2 after 9 minutes of exposure. A similar dose of 1 J/cm2 was also required to inactivate a viral load of 1 * 106 TCID50 H1N1 influenza virus 7. UV light disinfection is chemical free and thus a suitable method for applying in healthcare facilities to disinfect healthcare equipment 4. Most recently, a protocol for the disinfection of personal protective equipment (PPE) including filtering face pieces from health care workers described the potential use of ultraviolet light to inactivate SARS-CoV-2 6. Taken together, we demonstrated that UV irradiation is a highly effective method to inactivate the new corona virus SARS-CoV-2, even at the higher viral load levels that are found in research laboratories e.g. in cell-culture supernatants or in diagnostic material taken from the respiratory tract of COVID-19 patients.

Gimme a break. You have to dig through dozens of DC-esque insults to find even a shred of potentially useful information and even then it’s back and forth with “my data is better than yours”.

Take you off for 2 secs and there you are with your same dumb shit. The article you referenced doesn't state any age and you thought you had something because of the word pediatric. It was a 20 year old that died that weekend.

People just have a really difficult time understanding that this thing spreads very easily by close proximity to people and very little via fomite transmission. Places people are close to each other the most INSIDE are bars, restaurants and gyms (some of them). We way overreact to sanitizing ans cleaning surfaces but way underreact to social distancing.
It will be really be telling what happens in the fall and winter with kids going back to school. We'll be able to see if asymptomatic spread (children in school) will infect their older teachers and parents. My guess is they will. [Reply]
I just saw that the HS in Georgia that made the news with week with the pic of a shoulder to shoulder hallway has shut down and gone to online learning after 9 people came down with Covid 19. [Reply]

Just talking with a buddy of mine about this very thing tonight. Initially, I was all in on the sanitizing etc. but wasn't sure about the mask, when the exact opposite would have been the best course of action. It's amazing how effective masks and social distancing have been. [Reply]

Naw. If you want to skip the lion's share of DC-esque insults, it is pretty easy to know which posters should just be skipped or at least skimmed.
Even if this is no more than a toned down DC thread, those of us who rarely or never go over to DC, still appreciate it. [Reply]

That I cannot tell you. I admit it's an odd deal. I don't think that's on the media. It was at KU Med or Shawnee Mission. I can't remember which one now. [Reply]

So we have had approximately 338k kids test positive for Covid and just in the last two weeks around 100k. We could have predicted that?
I think we can stop with the notion kids can't get this or spread it to others. The upside is very few deaths but at least here in the US alot of kids are raised by their grandparents or older parents who they will pass this on to and they will get it and die. [Reply]

It's almost like the flu is more dangerous to children.

Put Hepa filters all over the place.
Teachers unions are now demanding that either more filtering be done through the HVAC systems or all rooms have fans put in them to draw air out through open windows to reduce the amount of internal air recirculated in the room [Reply]

It's likely that number has been consistent thru this whole thing and we're just now testing them as the amount of tests have risen to this level. [Reply]
