We can stop COVID in 3 months
In December, health authorities in Canton Graubunden announced that they were able to reduce the number of weekly infections by 73% in just one week! [1]
Imagine if we could do that everywhere, every week. For Switzerland, a weekly 73% drop would mean going from 20,000 new cases per week [2] to under 10 cases per week in just 7 weeks. Even the USA could go from 1.8 million cases per week [3] to under 10 cases per week in just 11 weeks!
Today that seems like an impossible dream. The data confirms our attempts to combat the spread of the COVID have not been very successful. For lack of better alternatives, slowdowns, shutdowns and lockdowns seem to be the only tools available to our health authorities, even though they come at huge cost to society.
We can make this dream a reality. This article identifies the “points of light” that will make it possible. All we have to do is connect the dots.

The “R-Values” measure how effectively the virus spreads. A value of 1 means the virus passes itself itself on to one other person. Its population remains constant. A value greater than 1 means the virus is spreading, and a value below one means the virus is dying out.
In February, COVID was spreading in Switzerland without resistance. Each infected person passed the disease to up to four other people! To avert a total breakdown of the health care system, the government first asked people to (1) wash their hands and observe other hygiene measures, then, two weeks later, (2) ordered a complete shutdown.
What impact did these measures have on the spread of Corona? Very little! The trend in R-Values was already going down before the measures were put into effect, and continued to decline at the same rate afterwards, until hitting a floor around 1.0, where, except for some blips, the level has stabilized.
The measures were not totally without impact. In particular, the reopening of schools and businesses (4) had some effect, and allowing large events (5) caused the R-Values to go up way up, due to super-spreader events they enabled. The evidence is strong that big events should be curtailed.
What’s not working? Wearing masks, contact tracing, the COVID app and our current approach to testing don’t seem to be up to the task of eradicating the virus. Most of the time, we are keeping the R-Value close to one, but just barely. When the measure fail, the R-Values go up, and the infection numbers go quickly through the roof. Most likely, the reaction times are too slow for these measures to be really effective. If people are contacted, by the time they are contacted, they have already spread the disease.
In short, slowdowns, shutdowns and lockdowns are barely sufficient to contain the disease. How can we beat this disease?
In Switch, How to Change When Change is Hard, authors Chip Heath and Dan Heath described a case about solving the problem of child malnutrition in Vietnam, which was once widespread. By identifying children who weren’t malnourished, the social workers could identify ways to properly nourish children that were both viable, that is they worked, and acceptable, that is would be accepted as “our” solution by Vietnamese parents rather than an alien approach imposed from outside. Heath and Heath called this approach “Points of Light.”
I have been following the developments around COVID-19 since it broke on the scene in March. I believe I have identified two points of light. If we can connect the dots, we can eliminate COVID, and we can do it quickly!
Looking for points of light
In December, health authorities in Graubunden, Switzerland reported that they had reduced daily infections by 73% in one week! How did they do it? They tested the entire population. Many people had no symptoms but were contagious anyway. They isolated everybody who tested positive.
This is a point of light in an otherwise dark, depressing landscape. We’ve done it before. We can do it again. Test everybody. Isolate those who are infected. If we could do this everywhere, every week, we could virtually eliminate the disease in no time!
What would happen if this success could be repeated everywhere, every week? In Switzerland, the virus would be virtually eliminated in about 7 weeks. In the USA, with about 1’800’000 new infections per week, it would take about 11 weeks.
What makes it hard to do this everywhere? Tests are expensive and need specialists to perform them. If each test costs $200 and takes 24 hours (the current list price at the University Hospital in Zurich), the cost of testing the entire population even just once is prohibitive; the cost to do it on a weekly or daily basis would be unsustainable. Such tests cannot be used at the turnstile, both because of the costs and because the response times are too slow.
What if a COVID test were so cheap and so easy that anybody could give the test as often as needed? What if it were so fast, you could use it like a ticket at the turnstile? Only let people get close to you if they are free of the disease.
With a fast, cheap, and easy test, you could test anybody, any time. You could check guests before you let them in your home. You could check passengers before they board an airplane. You could check staff before they start work. If you had high confidence that the people around you were free of COVID, you could meet, sing, party, conduct business and travel normally. COVID wouldn’t have a chance and life would go back to normal.
The second point of light
According to various news reports, there is an app for that. Researchers from at least three major universities (EPFL [5], MIT [6] and CMU [7]) have created AI-based programs that listen to your cough and diagnose whether your have COVID. The MIT project has reported accuracy comparable to the $200-PCR test.[8] The apps should be just around the corner. They could be installed on your phone. They could be free.
Except that was months ago. Why aren’t these testing tools available? When can we download them to our phones? There are many possible explanations. The teams might challenged by actually creating a releasable product. The regulatory authorities might be dragging their feet on approval. Pharma companies looking to make billions on tests and vaccines might be putting sand in the gears of the regulators. Maybe the tech giants are wrestling for control over the data to be generated. Maybe the tests don’t actually work that well.
It’s time to connect the dots! These apps can change the course of the pandemic. We need them, and we need them now!
If you are working on one of these research projects, I call on you to focus on getting the fruits of your research into the app stores. Make a version your app free and private, so anybody can use them without fear. Work with vendors to make professional versions that suitable for use at public places, like airports, train stations, clubs, sports and other large events. If your tools are really not ready, communicate frequently and openly, and ask for help, to make working solutions available without delay.
If you are a public health agency, I call on you to reach out to these research projects and find out how they can help you and us eliminate COVID now! Incorporate these ideas into your planning. Forget lockdowns — test often! Employ strategies that bring results quickly without shutting down the economy.
We can shut down COVID in time for Spring vacation. We have the tools. We just need to make them available and take full advantage of them.
