- We have done an investigation on Ebba and Charlotte - and it is more likely that they have been affected by a virus, says national team doctor Per Andersson to Expressen.

Kalla, Andersson, Moa Lundgren and Emma Ribom were sent home from the camp earlier this week.

Then the national team management suspected food poisoning.

Now studies in Stockholm show that they are probably affected by stomach virus.

Confusing diagnosis

However, the diagnosis puzzles Per Andersson.

- It has had effects for a longer time than we normally see.

It has been a tough story, says Per Andersson.

Both Charlotte Kalla and Ebba Andersson are on the road to recovery.

- When I talked to them yesterday, both were more alert, Per Andersson says to Expressen.
