There is a rose leaf curl virus.

The following link states: "In the United States, the infectious agent of rose leaf curl occurs in many Âantique" roses in community rose gardens. The disease is widely distributed in the United States, but when it is seen in hybrid tea roses in public gardens, "antique" roses are usually nearby." http://web.aces.uiuc.edu/vista/pdf_pubs/632.pdf

That paper is rather old, is rose leaf curl still considered a problem? The following is from a March 2009 University of California paper:

"Infected rose plants. Slow natural spread." See:

Here is a link that might be useful: March 2009 article

Since you are in New Port Richey, why don't you join the Tampa Rose Society and ask some of the experts there? They meet in North Tampa not too far from you. Also, there is a great group meets in Lakeland, the Central Fla. Heritage Rose Society,....... also the Central Fla. Rose Society in Orlando has a group of consulting rosarians if you want to drive that far...... the Tampa Rose Society has a web-site, just Google it, and contact them...... sally
