Here's an interesting article and I'm sure of one thing - this study will be controversial. What do you think, are most of us overestimating or underestimating our risk of getting Covid-19?
Controversial California Study Claims Americans Are Overestimating Their Risk Of Getting Coronavirus And That The Odds Of Infection Are Around One In 4,000
Researchers looked at coronavirus case incidence data for the week ending May 30 in the 100 most populous US counties
They calculated that someone who has a single contact with an infected person has a one in 3,836 chance of getting sick themselves
For Americans between ages 50 to 64, the risk of being hospitalized is one in 852,000 and the risk of dying is one in 19.1 million
The team says action from governments, media attention, and the lack of feeling in control may be influencing the perception of risk
"Americans may be overestimating their risk of contracting the novel coronavirus, a controversial new study from California suggests.
Researchers found that, on average, a person who has a single contact with an infected individual has a one in about 4,000 chance of becoming sick, without using preventive measures such as social distancing or wearing a mask.
For the middle-aged, the risk of hospitalization is nearly one in a million and the risk of death is almost one in 20 million.
The team, from Stanford University and the University of California Los Angeles, says action from local and state governments, attention from the media, and the lack of feeling in control may be influencing the public's perception of risk."
I think the risks have changed a bit since that study was done (for example, at that time the case rate in California was half what it is right now). I'd say the chances are greater than 1 in 4000 right not - probably more like 1 in 3000. If you look at the projections from all universities at the end of May, they were much more optimistic than they are right now - because not even the Memorial Day data had come in yet. And frankly, I knew no one in May who had CoVid, and now I do. And now I have a family member who has it, whereas until a week ago, it was all people who were outside my own family and friend group.
However, having said that,
those odds don't apply to those with jobs in hospitals or urgent care centers. So
the odds are not evenly distributed through the population. People who have public-facing jobs (TSA agents for example) have a much higher rate. So the general public may be alarmed by the stories, but some real people in real jobs have a much higher risk. I worry very much about grocery store workers and truck drivers in the refrigerated sector. 500 Delta workers are positive. Other airlines are remaining silent, but you can guess at their rates. Perhaps Delta has 2,000,000 workers but I doubt it - instead it's likely that the odds of getting CoVid while being involved somewhere in the air travel business are much much higher (which means the odds are lower for many others). (If anyone knows how many employees Delta has, please share!)
Those of us who work with populations where transmission is mostly silent (partying college students for example) are at higher risk too.
So, each of us has to do our own risk assessment. I think my risk is considerably higher than 1 in 4000 were I to go back to my regular job. As I actually have been in touch with one of those Stanford researchers (who is working from home, btw), I think we see eye to eye on it. I would be someone who is older than 64 in touch with the population that has
I am also not in the age group 50-64 (I'm a bit older). Google analytics shows that people aged 18-25 in my area are much more social than the average American is right now. Lots of variables - and since each person has been given so little information and most get it from MSM, realistic risk assessment is difficult.
So if someone told me that 1 in 4000 small planes were going to crash over a 3 month period, I wouldn't fly in one. If there were a 1 in 4000 chance that the big tree outside my house was going to fall on my roof tonight, I'd go to a hotel. But we're all different. If a person has had a serious illness that only afflicts 1 in 100,000, they view things differently.
My personal desire is to avoid contexts in which my chances of running into a CoVId+ person are less than 1 in 100 - while I'm wearing a mask. And at 1 in 3000 (which is closer to the real rate today, June 23 than the rate in the article based on earlier data), I'd still wear a mask.
The spaces I work in involve about 1000-3000 bodies in the building per day, with A/C and recirculated air. Sometimes it's higher than that (beginning of semester). If I'm in one of the big classrooms in a big building, it's about 5000 young people in the building per day. Just my regular classroom sees 1800-2000 pass through it on the daily. There's almost always someone coughing...at first administrators tried to match the "more vulnerable" (code for Old Profs) to the smaller buildings and classrooms (they even thought about trailers but that didn't make sense either, due to expense and having to put so few students in each A/C'ed unit - it gets too hot for public health to allow occupancy otherwise). But it turned out that there were way too many "Old Profs," as well as people with immune disorders, and who are family of vulnerable people.
So it's not to hard for some of us to come into contact with 4000 people in a matter of a few days. Do you feel lucky? I don't feel lucky regarding this one - and I can't say why.
I'd love to hear which of those researchers actually plan to teach large lecture courses and are going to still consider their odds 1 in 4000. Or go to a Stanford football game, where in theory (according to them) there would 5-6 active transmitters of CoVId (in reality it would be higher because students party a lot during football seasons). Or to a music venue that seats 4000 indoors - where one person has CoVid. I truly do wonder if they, themselves, would bring their parents or families to such an event.
If I lived in rural New Mexico (a dream I"ll never realize), I'd feel very differently than living and teaching in Los Angeles. And it's interesting that both UCLA and Stanford have devised schedules that do not allow that kind of contact.
