- We in Skåne have no more cases now than previous August months, he says.

The Danish outbreak is concentrated mainly in Fynd and East Jutland. In August this year, 1,323 cases of whooping cough were noted, which is as much as in the entire 2018 and 2019.

- I don't really know why there are so many cases in Denmark right now. There has been talk of increased attention, but that may not be the whole explanation, says Per Hagstam.

Dangerous for young children

In Sweden, whooping cough vaccine is included in the vaccination program. However, this is not life-long and one can very well get whooping cough as an adult.

- Sometimes you are not aware of it, says Per Hagstam.

Whooping cough is especially dangerous for young children.

- It is important to be observant and to take a test on those who have a long cough, says Hagstam.
