I took care of someone once with cat scratch fever. Her cat got her maybe eight hour prior and she was a gnats ass hair away from losing her finger by the time she got to us. I do not recall if they lanced it or not but she got a shit load of IV antibiotics and was well shortly after, finger intact
I absolutely would still know the signs and symptoms. Medicine is never perfect. Vaccines significantly lower the risk of infectious disease but its never zero. In the Philippines, I was exposed to measles a couple times without realizing until after. I got my MMR when I was young. Never showed a symptom. But still, always good to be careful.
My wife would probably appreciate that. The triangle life has not been good for her
