Well I don't personally have experience with the illness but a close friend of mine had it when I was a teenager. It's mostly only transmitted by saliva so if you wash your dishes well and don't share utensils the rest of the family may very well stay clear of the illness. The virus can actually stay in your system indefinately but does not cause any new symptoms after about 4-6 weeks. My friend seemed to be tired and sleep a LOT, LOT, LOT for about 2 months. She seemed fine otherwise. I think the biggest risk with the enlarged spleen, which as you said is common, is that you avoid contact sports or any blow to the spleen which can rupture it at this time. But if you figure that you feel like crap and tired anyway you probably won't be behaving very actively and risking that anyway. My friend recovered without being in the hospital at all during her illness but perhaps her spleen wasn't quite as enlarged. My mother-in-law was diagnosed with this illness as well and had been feeling extreme fatigue for months. Her health is shaky anyway and the virus was able to cause symptoms for longer because her immune system was too weak to overcome the virus in the usual time. She has since recovered but with her situation the Dr warned of a "relapse" or recurrance of the symptoms though this is unlikely even in her situation.
This is all I really know about the illness. Since you looked things up on the internet you very likely may have read the info at
WebMD. But here's the linky anyway. It is pretty thorough and I believe reliable.
