gerbils and diseases

[hila]

hey list , today I saw a program on the national geographic channel talking about diseases that are being spread by rodents as it was presented there , almost all kinds of rodents are carrying disease that can infect people.  well , I have my gerbils over a year now , I was beaten a couple of times , I am holding them, playing with them , they have touched almost everything in the house , and I am sure that a few times I forgot to wash my hands after touching them . I dont feel sick or anything and I guess you didn't get anything from your gerbils also . but yet , after seeing  this program I became a little worried . things where I live (Israel) aren't so quiet anyway .. so the last thing I need now is getting some dangerous disease from my gerbils . what is your opinion ?  since most of you are much more experienced in gerbils then I am , I will sleep better at night knowing there is no danger .   thanks ,   hila
