To: Janet Paterson From: Will Kuipers Re: Mono and PD? Hi Janet, What makes you ask the question? How contageous is the Epstein-Barr virus? I worked on a project with an engineering colleague, where I saw him once a week for an hour or so. He was a robust man who took pains to live a healthy life with plenty of exercise. I don't know when he contracted the Epstein-Barr syndrome, but during the year we worked together he deteriorated rapidly. He got to the stage where any small amount of work would fatigue him to the point that the rest of the day he was incapable of functioning. He was an engineer's engineer and any situation would be regarded by him as a problem to be solved. When he found that he was reaching the stage where he could not function any longer and would just be a burden, he concluded that there was no use in continuing and took his life. I cannot answer your question because I don't know if there is anything to watch out for. What, in your case, constitutes exposure? Your question interests me a lot and I hope that I can share in anything that you might find out. Greetings Will Kuipers <[log in to unmask]>
