- I hope that this is the first sign that it has turned around, says Lisa Labbé Sandelin, infection control doctor Region Kalmar County.

A signpost

The measurements in the wastewater are made in a number of places around the country, of which Kalmar is the only one in southern Sweden.

But the method of measuring the amount of virus in circulation in society through the wastewater is far too new to draw any major conclusions, says Labbé Sandelin.

- A colleague of mine expressed it as if they are like a compass but not like a GPS.

They give us the direction of where we are going.

Several parameters

Now that the general sampling has stopped, you have to check the spread of infection and the pandemic in other ways, says Lisa Labbé Sandelin.

The virus measurements in the wastewater are one, and there are more. 

- I check different parameters.

As an infection control doctor, I work in that way, for example when it comes to monitoring seasonal flu.

I look at the pressure on health care, I look at the burden on IVA, how many have covid of those who try, and then you can look at how many people contact 1177 when it comes to fever in children, says Lisa Labbé Sandelin. 

But at the same time she is hopeful about the test results from the sewer pipes:

- This is the expected development, that it will go down and we keep our fingers crossed for it, she says.
