Question Summary:
Does touching ham indirectly make other things impure?

Question Detail:

Does touching ham or pork indirectly cause something you touch to be napaak if no wetness was spread?
I was working in a classroom and some of the children eat pork for lunch, so the teacher wiped the table that had pork on it with a dishtowel to clean it, the next day I used the same dishtowel to clean another mess and just rinsed my hands and then I realized she had used that yesterday to clean pork and now I’m suffering from major OCD, waswassa problem because I think everything that I touched that day like my bag and pen and phone are napaak.

Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
 
Rinsing your hands was sufficient to obtain purity and everything you touched subsequently (such as your bag, pen, and phone) is pure.
And Allah Ta’āla Knows Best
