So interestingly, it, it begs the question as to whether we can prevent fatigue after infections and some years ago with Brigitte candy, who was a research nurse at the time working with us and Matthew hot off, and various other people. We tested the idea that hypothesis that a very brief intervention which included one face to face appointment with the patient when they had a definite diagnosis of EBV. Plus two subsequent telephone calls, which were quite brief, delivered by the research nurse, which was project candy, and this was delivered shortly after the onset of the glandular fever. We hypothesise that this would reduce fatigue symptoms at six months. And the information that we discussed with the patient or the content of the sessions was reinforced with a booklet. in that conversation, Bridget really concentrated very much on lifestyle management. So some advice about returning to work as soon as possible. But bearing in mind that had a nasty infection, and not to go sort of training for the marathon, particularly, they'd never been out on the treadmill before, you know, some sensible advice about not doing too much too soon. But also emphasising the importance of trying to get back into some activity, and then very gradually increasing it. Now, many of these people were young people, it's a young, young person's disease, that's probably why it's called the kissing disease. And people also were given some advice about the importance of a sleep routine, as many of these young people were kind of burning the candle at both ends. So it was sensible advice. And what we found is that, as you can see here is that at six months, those people who got the intervention from the research nurse who wasn't a trained therapist, by the way, that they were less fatigued at follow up. You can see there's a deaf, it took a little while for that separation to occur, sort of suggesting that there was a bit of a delay between the time being given the information and the time that the information really had an impact.
