About two weeks ago, the first case of the legionella bacteria was discovered in staff at the Yasuragi hotel and spa facility outside Stockholm.

Just a few days ago, it became clear that yet another of the employees had fallen ill, which Expressen was the first to report.

- It is not possible to say one hundred percent that it is coming from there, but it is highly likely that it is coming from staff areas, says Per Enarsson, environmental manager at Nacka municipality, to SVT.

Been open despite infection

The bacterium infects via water droplets and thrives in temperatures between 20-45 degrees.

As a precaution, they have raised the temperature of outgoing water further, according to Per Enarsson.

The facility's water systems are separate and have one for the spa, one for the kitchen and one for the staff showers.

- Since the samples in the public part have not shown anything, we have not shut down the business.

As a precautionary measure, however, the spas themselves decide on Friday afternoon to pause the facility pending new test results.

Smittskydd Stockholm also investigates whether the infected bacteria come from the same bacterial strain.

In the meantime, cleaning of the premises and cleaning of water filters is underway.

- With the measures that Yasuragi has taken and that the infection most likely comes from staff areas, visitors do not need to feel any concern about getting sick, says per Enarsson.
