Final answer:
Proper hand hygiene and surface disinfection are key for preventing infection in a nail technician.
Step-by-step explanation:
The best way for a nail technician to prevent infection is to practice proper hand hygiene. This includes washing hands thoroughly with soap and warm running water for at least 20 seconds, paying attention to commonly missed areas like the thumb, wrist, areas between the fingers, and under the fingernails. It is recommended to use a nail brush to remove any debris or microorganisms under the fingernails. Additionally, following strict protocols for surface and equipment disinfection can help prevent the spread of infections.
