According to information provided by the Centers for Disease Control and Prevention (CDC), the best option would be puncture wounds.
Highlighted transmission methods include the following:
- Wounds contaminated with dirt, feces, or spit (saliva)
- Wounds caused by an object puncturing the skin (puncture wounds), like a nail or needle
- Injuries with dead tissue
- Clean superficial wounds (when only the topmost layer of skin is scraped off)
- Surgical procedures
- Insect bites
- Dental infections
- Compound fractures (a break in the bone where it is exposed)
- Chronic sores and infections
- Intravenous (IV) drug use
- Intramuscular injections (shots given in a muscle)
I hope this helps! Have a good evening!
