Excellent information (not happy though) from Jonathan Smith, an epidemiologist from Yale.

From Yale Epidemiologist, Jonathan Smith:

"As an infectious disease epidemiologist, at this point I feel morally obligated to provide some information on what we are seeing from a transmission dynamic perspective and how they apply to the social distancing measures. Like any good scientist I have noticed two things that are either not being articulated or not present in the “literature” of social media. I have also relied on my much smarter infectious disease epidemiologist friends for peer review of this post; any edits are from that peer review.
Specifically, I want to make two aspects of these measures very clear and unambiguous.
First, we are in the beginning of this epidemic’s trajectory. That means even with these distancing measures we will see cases and deaths continue to rise globally, nationally, and in our own communities in the coming weeks. This may lead some people to think that the social distancing measures are not working. They are. They may feel futile. They aren’t. You will feel discouraged. You should. This is normal in chaos. But this is normal epidemic trajectory. Stay calm. This enemy that we are facing is very good at what it does; we are not failing. We need everyone to hold the line as the epidemic inevitably gets worse.
This is not my opinion; this is the unforgiving math of epidemics for which I and my colleagues have dedicated our lives to understanding with great nuance, and this disease is no exception. I want to help the community brace for this impact. Stay strong and with solidarity knowing with absolute certainty that what you are doing is saving lives, even as people begin getting sick and dying. You may feel like giving in. Don’t.
Second, although social distancing measures have been (at least temporarily) well-received, there is an obvious-but-overlooked phenomenon when considering groups (i.e. families) in transmission dynamics. While social distancing decreases contact with members of society, it typically increases your contacts with family members /
very close friends. This small and obvious fact has surprisingly profound implications on disease transmission dynamics. Study after study demonstrates that even if there is only a little bit of connection between groups (i.e. social dinners, playdates/playgrounds, etc.), the epidemic isn’t much different than if there was no measure in place. The same underlying fundamentals of disease transmission apply, and the result is that the community is left with all of the social and economic disruption but very little public health benefit.
You should perceive your entire family to function as a single individual unit; if one person puts themselves at risk, everyone in the unit is at risk. Seemingly small social chains get large and complex with alarming geometric speed. If your son visits his girlfriend, and you later sneak over for coffee with a neighbor, your neighbor is now connected to the infected office worker that your son’s girlfriend’s mother shook hands with. This sounds silly, it’s not. This is not a joke or a hypothetical. We as epidemiologists see it borne out in the data time and time again and no one listens. Conversely, any break in that chain breaks disease transmission along that whole chain.
In contrast to hand-washing and other personal measures, social distancing measures are not about individuals, they are about societies working in unison. These measures also take a long time to see the results. It is hard (even for me) to conceptualize how on a population level, ‘one quick little get together’ can undermine the entire framework of a public health intervention, but it does. I promise you it does. I promise. I promise. I promise.
You can’t cheat it. People are already itching to cheat on the social distancing precautions just a “little”- a playdate, a haircut, or picking up a needless item at the store, etc. From a transmission dynamics standpoint, this very quickly recreates a highly connected social network that undermines all of the work the community has done so far.
Until we get a viable vaccine this unprecedented outbreak will not be overcome in one grand, sweeping gesture, rather only by the collection of individual choices our community makes in the coming months. This virus is unforgiving to choices outside the rules.
My goal in writing this is to prevent communities from getting ‘sucker-punched’ by what the epidemiological community knows will happen in the coming weeks. It will be easy to be drawn to the idea that what we are doing isn’t working and become paralyzed by fear, or to just‘cheat’ a little bit in the coming weeks. By knowing what to expect, and knowing the importance of maintaining these measures , my hope is to encourage continued community spirit, strategizing, and action to persevere in this time of uncertainty."

Not much human contact. There are a few bright spots, however. One is my cat. She wakes me up around 6 am, wanting her breakfast. So, I get up and feed her the morning ration of Fancy Feast. Later, she will come to the side of the chair where I'm reading DU and nudge me with her paw, telling me she wants to be petted and brushed. Not really human, but a welcome contact with a friend. Could you adopt a pet cat or dog? It won't take the place of human interaction, but it does help a lot. Hope this helps! **virtual hug**
So calm. It makes her more convincing, to me, at least.
Greetings from Victoria! 
Greetings from Nanaimo!
What ticks me off is that this information isn't coming from a CDC scientist on a daily or weekly basis on a national news platform. It's like there's an Underground Railroad of responsible information about this pandemic but you have to either be in the right place at the right time to find it, or you have to spend hours a day hunting for it. I don't mind hunting for it, but many people don't have that luxury.
Thanks for posting this. Another gem I wouldn't have seen otherwise.
