How long does hsv-1 last on the surface after touching a cold sore and touching the area. and can i catch hsv-1 from touching an infected area?

No risk, no worry: The second part of your question is the only important part: nobody ever catches HSV (either HSV1 or 2) by contact with contaminated surfaces or objects -- only by direct intimate contact with an infected person. Since this never happens, the time the virus surviives on surfaces doesn't matter. (It's probalby very brief, though -- for sure the viirus dies when contaminated fluids dry out.)
