Uhhh how dangerous is this?

So roughly 62 hours ago a coworker dropped my knife and cut themselves as it fell at the time I couldn't find anything to sanitize my blade with and ended up forgetting about it. Didn't look like any blood on blade very minor cut.

62 hours later give or take on break and I needed to cut my food but all the utensils were out so I was like whatever whipped out my pocket knife.. 20 minutes after break im like oh shit! As i remembered incident and my lack of sanitizing blade.

So for those more educated than I about this stuff how much did I fuck up here? If I'm at risk how long should I wait to get tested since incubation periods. I dont have insurance so I'd rather not go in a bunch of times. I'm fully planning on getting tested anyways soon but now I fear I need to factor in this incident and frankly put I'm kinda freaking out internally I know that shit only needs a drop to infect someone idk if this coworker is ill and the internet is giving me a wide assortment of awnsers. So uh please advise guys
