More governments across the world are saying they're ready to "live with the virus." |
For a look at the new approach, I spoke to Camilla Holten Moller, the head of the expert group for mathematical modeling at the Statens Serum Institute, the public health agency in Denmark that tracks the virus and advises the government on how to approach Covid. |
Your institute recommended that the government remove virus restrictions. Why did you do that, given that cases in Denmark are rising? |
We based it upon a really precise picture of the development of the epidemic, and what we saw with the Omicron variant taking over in the country. |
Overall, the Omicron variant is less severe. So even though we see really high case counts, we don't need to flatten the curve like we used to, simply because we don't see as severe a picture as we used to — with Delta for instance. |
When we look deeper into the numbers of hospitalizations, what we see is that we have a low and stable number of admissions to intensive care units. Yesterday I think we had 26 admissions to I.C.U.s, which is really low given that we also had 55,000 new cases. |
So for us, here in Denmark, it is extremely important that we can accept to not flatten the curve, to let loose the epidemic, to accept that it can grow, as long as it doesn't cause severe illness. |
How are people in Denmark feeling about the lifting of restrictions? |
I think overall the majority are simply happy that the restrictions are lifted and that we can start to get back to normal. The main task now is to protect those who are still at risk, like the elderly population or the immunocompromised. And there are still some measures in place that protect those who are at risk. We still recommend mask-wearing and taking a test before visiting hospitals and nursing homes. |
In general, people are still wearing masks in some places — in the supermarkets or in the metro — but I think overall people may accept that it's their responsibility to take care of those who need to be protected. But it's more up to you to do that sort of risk assessment of your own. |
What does your modeling say about the country's future? |
We released the latest modeling results just before Christmas, and we projected that we would see the peak of the epidemic here in late January, with hospitalizations peaking a little bit later, in mid-February. But what we've seen is that BA.2 [the Omicron subvariant] is more transmissible, there's no doubt about it. And that means that we would expect the peak be to be a little bit higher and maybe extend a little bit into February. |
But so many people have had an infection or have been vaccinated in certain geographical areas and in certain age groups that it simply slows down the growth of the epidemic. Of course, opening up and lifting all restrictions could lead to additional growth, especially when you open the nightlife. But we still see that the population immunity is so high that we still expect the peak to come within the coming weeks. |
So is this the end in Denmark? |
No. We are quite alert that something new could happen. And both the Epidemic Commission and the government have clearly stated that they are ready to act accordingly. |
What we know is that immunity from SARS-CoV-2 isn't lifelong immunity, like the immunity from measles, for instance. That means we will have waning immunity. We know what waning immunity looks like from the seasonal flu. Each winter people get back together inside, immunity starts to wane, you have new strains, and you start to see a rise in the flu and a small epidemic occur. |
It's also possible that we still have Omicron in the fall, and we see another peak then, simply because immunity will start to wane in the population. And that would probably mean we would do something, maybe start vaccinating again, or testing to a higher degree, or whatever other tools we have to contain that wave. |
Last January, researchers searching for the coronavirus in New York City's wastewater spotted something strange in their samples: viral fragments with mutations that had never been reported before in human patients — potentially a sign of a new undetected variant. |
These oddball sequences, or what the scientists call "cryptic lineages," have continued to pop up in the city's wastewater over the past year, my colleague Emily Anthes reports. There is no evidence that the lineages pose an elevated health risk to humans, but the researchers are torn about their origins. |
Some suspect that the virus is coming from people whose infections aren't being sequenced. But others think that the lineages may be coming from virus-infected animals, possibly — wait for it — the city's enormous population of rats. |
What else we're following |
I am still isolating most of the time, although I think the risk is much reduced in my area, and I'm fully vaxxed. The reason? My professor is immunocompromised, and is still as much at risk as he was during the worst of times, even with three jabs. I'm timing my shopping and socializing so as to reduce the likelihood of infecting him, and using one of the government rapid tests if I think I may have been exposed, in case I do become infected. As a nation we seem to be willing to ignore the needs of those who can't protect themselves. In some cultures they used to put their old people out in the snow to die of exposure. We don't seem to have moved beyond those times. — Meg, Chicago |
