Found myself at the barber shop this afternoon for a fresh cut and shave. Was starting to look like sasquatch. Apparently the shop has been taking clients quietly throughout the closure. Another local restaurant is opening May 27th, and reservations were gone almost instantly. Owner asking other restaurants locally to hopefully join

Here's an interesting article in Science magazine that was published today. Why do some COVID-19 patients infect many others, whereas most don’t spread the virus at all?
Quote: That’s why in addition to R, scientists use a value called the dispersion factor (k), which describes how much a disease clusters. The lower k is, the more transmission comes from a small number of people.
...
Why coronaviruses cluster so much more than other pathogens is “a really interesting open scientific question,” says Christophe Fraser of the University of Oxford, who has studied superspreading in Ebola and HIV. Their mode of transmission may be one factor. SARS-CoV-2 appears to transmit mostly through droplets, but it does occasionally spread through finer aerosols that can stay suspended in the air, enabling one person to infect many. Most published large transmission clusters “seem to implicate aerosol transmission,” Fraser says.
...
Individual patients’ characteristics play a role as well. Some people shed far more virus, and for a longer period of time, than others, perhaps because of differences in their immune system or the distribution of virus receptors in their body. A 2019 study of healthy people showed some breathe out many more particles than others when they talk. (The volume at which they spoke explained some of the variation.) Singing may release more virus than speaking, which could help explain the choir outbreaks. People’s behavior also plays a role. Having many social contacts or not washing your hands makes you more likely to pass on the virus. (Emphasis mine.)
Much more of interest at the link. ~z

New infographic alert--
An article in ProPublica: States Are Reopening: See How Coronavirus Cases Rise or Fall
There is an interactive chart on all the states in the U.S. that shows "the trajectory of each states's positive tests as a percentage of total tests, over the last two week."
The information is sourced from: The COVID Tracking Project, National Governors Association, CDC COVID-19 Module, CDC FluView. By clicking on the individual state designated on the initial map you are taken to that state's metrics and results. ~z

New peer-reviewed study in Science suggests people do develop protective antibodies that prevent reinfection. Research is in primates. Good news for people who have survived the virus, and also for vaccine development.
SARS-CoV-2 infection protects against rechallenge in rhesus macaques
https://science.sciencemag.org/content/early/2020/05/19/science.abc4776
Quote: | An understanding of protective immunity to SARS-CoV-2 is critical for vaccine and public health strategies aimed at ending the global COVID-19 pandemic. A key unanswered question is whether infection with SARS-CoV-2 results in protective immunity against re-exposure. We developed a rhesus macaque model of SARS-CoV-2 infection and observed that macaques had high viral loads in the upper and lower respiratory tract, humoral and cellular immune responses, and pathologic evidence of viral pneumonia. Following initial viral clearance, animals were rechallenged with SARS-CoV-2 and showed 5 log10 reductions in median viral loads in bronchoalveolar lavage and nasal mucosa compared with primary infection. Anamnestic immune responses following rechallenge suggested that protection was mediated by immunologic control. These data show that SARS-CoV-2 infection induced protective immunity against re-exposure in nonhuman primates. |
Caution though, sample size is only 9 primates.

A lot of the news is more akin to Silicon Valley vaporware than scientific research. It is seldom peer reviewed or proper double blind experiments. I am hopeful but not blind. My daughter is in research and I know how difficult and time consuming it is to get accepted in a reputable journal. Do not trust general news media to provide accurate information.

This, for several reasons, and primarily (in my opinion), to sell ads, not to inform.

Would have been more interesting if they interviewed those at high risk. While lower risk groups aren't in the clear without a vaccine, strikes me as less important if they opt out.

Here's a recent article in the Salt Lake Tribune published today. How the coronavirus spreads in those everyday places we visit
Quote: It hasn’t even been five months since health officials in Wuhan, China, reported unusual pneumonia cases to the World Health Organization.
But those five months have been the most active in the history of epidemiology. Since that report, we’ve learned so much about the coronavirus. One of the most important lessons? How the disease is spread.
In particular, so-called superspreading events seem to be a major cause of infections. One London School of Hygiene analysis suggested that 80% of the secondary transmissions were caused by just 10% of infected people. In other words, if you want to avoid getting COVID-19, one of your major focuses should be avoiding a superspreading event.
Then it goes on to describe a variety of events and situations that we find ourselves in and how likely we are to get the virus there. It uses well-documented instances of cases from these events, e.g. bars & clubs, buffets, buses, choirs, church, family gatherings, grocery stores, gyms, malls, offices, planes, polling places, schools, and sports venues and stadiums.
It describes a spreading event in each of these places--or not and lessons learned about avoiding situations that might put us at risk. It's not perfect and many of us know these things already, but I thought this presentation was accessible and worth having a look at. ~z

Lately, I feel like we are doomed. So many people are not educating themselves and are believing what they want to believe rather than what experts are recommending. Here is an example.
From The Guardian--stores are banning masks
What's especially fun about sock puppets is that you can make each one unique and individual, so that they each have special characters. And they don't have to be human––animals and aliens are great possibilities
