Virus on Iphone?

Alright, i know alot of people are saying that iphones cannot be infected and all but i need reassurance.

1. I download illegal music online on my laptop and sync them into my itunes and later into my iphone 5s.

2. days later i found out that my laptop has been infected with the virus from the free music i have downloaded.

3. All i want to ask is, is my iphone 5s infected now? since i sync the music from the laptop into itunes and into the iphone.
