It looks like a clickbait headline but it is one that is right, you don't see that often.
Het Artsen Covid Collectief (waaronder 1672 geverifieerde medici) postte op hun website een artikel met de kop: "Deltavariant in opkomst. Geen reden tot paniek."

Pressure on hospitals next autumn?
In the article, the collective doctors united attention to the capacity problem in healthcare. They say:
Every winter there is a flu peak that puts healthcare to the test. The cause of this is the capacity problem and not the severity of the annual seasonal viruses.
The Doctors' Collective forgets something essential
What they don't name is the cause of the misery surrounding the annual flu wave. Until now, our virologists have had no idea how respiratory viruses spread every year. This has been revealed by corona. They have accepted the transmission issue, in my view rather nonchalantly, as a fact of life. No one made a problem of the annual flu explosion. Over the past year, this knowledge gap has undeniably been exposed.
Thanks to Corona and all the scientific attention it has attracted, we now know exactly how it is. The advancing insight has made a huge intermediate sprint. With that, the virologists have fallen through the ice quite a bit due to corona with their group think, tunnel vision and old-fashioned doctor arrogance. That is why I make a suggestion below for an extra heading in the piece of the doctors' collective:
No more pressure on healthcare in the autumn!
The doctors' collective sees the capacity problem as the cause of the pressure on healthcare and that is a typical healthcare perspective - apparently you cannot escape it. Healthcare workers seem to forget that this shortage of capacity is because many people are suddenly infected at the same time. We now finally know why that happens. For decades, health institutes and virologists have allowed thousands of people to die from flu every fall without taking action. This can be improved from now on.
Thanks to all the corona research, this virus (whether grown in the lab or not and therefore easily traceable) has taught us how respiratory viruses spread. We can now estimate in advance how many people will die next year without having to wait to see where and when an annual excess mortality peak will occur. Until now, these annual mortality peaks have never been included in the mortality estimate. After all, mortality is always 'more than expected': excess mortality. That will all be different now because it is easier to control and therefore also easier to estimate. Now we know how people can easily protect themselves.
Meestal wordt deze zin in de passieve vorm gebruikt: "hoe mensen beschermd kunnen worden". Vele malen belangrijker is dat mensen zélf weten hoe ze zich kunnen beschermen: met frisse lucht. Dan heb je de belangrijkste piek al afgevlakt. Toch gaat het kabinet maar door met het propageren van schijnveiligheid, zoals "15 minuten per dag je huis luchten". Geen flauw benul dus. Hieraan herken je de kwaliteit van de medische raadgevers.
De medisch adviseurs van iemand die beweert "Een kwartier per dag luchten is afdoende" tegen een virus dat net op de A-Lijst is geplaatst zouden wat mij betreft met pek en veren het land uit gestuurd moeten worden.
Self-protection first: more about CO2 meters
Het artikel van het artsencollectief was een broodnodig antidotum tegen de kip-zonder-koppige angstzaaierij alom. De Deltavariant wordt in context geplaatst. Ze leggen duidelijk uit dat een besmettelijker virus bijna altijd een goed teken is omdat het minder gevaarlijk is oftewel "endemisch" wordt, net als verkoudheid. Niet dat ik van verkoudheid nu zo blij word maar vooruit.
A very deadly virus will quickly make its host persons (='hosts' but inclusive) ill and eliminate them, which reduces the number of infections and therefore rapid spread. If this is new to you, please read the article.
Tomas Pueyo (die van Hammer & Dance) ontkent dit principe trouwens en This leads to ominous scenarios. If one thing has become clear from this crisis: doomsday scenarios never come true. Not even those of Geert Vandenbossche and Mike Yeadon.
It is said that the British variant already had a lower IFR (approx. 0.05%) and that the Delta variant is even lower (approx. 0.01%). I will mention the (not yet peer reviewed) numbers. The doctors are quite rightly more cautious. I have not yet seen any data that contradicts these figures, but that will have to happen. After all, people want to attribute the declining disease and mortality to the vaccinations. This means that Delta must remain extremely dangerous with a high IFR. The vaccinations are then the protective factor that lowers the IFR. At the same time, you see everywhere that Delta no longer cares so much about the vaccinations... A difficult situation.
