Kate was still nervously monitoring Vitali's condition. Now, Vitali was still in danger, but his condition was ultimately much better than when he had first arrived.
Had it not been for Woody's judgment and persistence, Vitali would have died. No, actually, when Vitali had just arrived, he was practically dead in some respects—hemorrhagic shock had already caused his heart to stop beating, so it was Woody who had snatched him back from the hands of death.
Woody was still busy. He stuck by Vitali's side constantly, as creating a sterile environment was really killing him.
The dead do not need to worry about infection, but the problem was that Vitali had survived, and that meant Woody had to figure out how not to let Vitali get infected.
So Woody temporarily converted a room into a makeshift sterile ward. Of course, it couldn't compare with the sterile environment of a hospital, but after repurposing a bedroom into a ward, he dared to say he had done his best.
