After the incident with Sarah, it became clear that the "infection" of Demiurge was indeed spread to other people as well. The scientists that took the risk to travel to Babylon 12 when Them was still in power in the station were isolated immediately after they were extracted from the station. While they didn't show any signs of Demiurge infection initially, people in charge of cleanup were about to let the scientists go.
That was before Sarah showed signs, but as the infection in Sarah became apparent, the scientists were kept in isolation for an extended period of time. Atkoosa, with the help of Mätuk, went to investigate the scientists and found, with careful observation, that they were indeed infected.
As such, the same procedure that was done with Sarah was done to the scientists. After that, those who were taking care of the scientist's isolation were also made to go on isolation in a different place just in case it was spread on them as well.
