Do they have to divulge whether a home had a death?

Do Real Estate Agents have to divulge whether a home they are attempting to sell has had any "deaths" in it?

I know this sounds crazy...but my wife and I are into those ghost shows on television but as someone who's had a relative die in their home...it does creep me out moving into another home that has had a death. Are agents supposed to tell a buyer whether the house has 'history' such as death. If not, are they required if asked?

Thanks
