A 23-month-old male’s mother called to the clinic after she had found her son holding a single razor blade near a garbage can in a park. He dropped the blade and the mother immediately checked his hands. She says that he appeared to have no cuts or scratches on his hands or other body parts. She immediately used an alcohol-based hand sanitizer gel on his hands to wash them, then brought him home and washed his hands with soap and water. She had picked the razor blade up herself with tissue and discarded it after wrapping it in several other layers of tissue and putting it into an open tin can in the trash. She was now calling because she was worried that he might contract Human Immunodeficiency Virus. The resident taking the phone call ascertained that he did not have any area of his skin where it was broken such as a hang-nail, or rash, that he was otherwise well and that he was current with his immunizations. The mother said that the razor blade was triangular and looked more like a utility razor blade than a rectangular single- or double-sided blade used for shaving. She also noted that it had some rust on it. The diagnosis of a potential exposure to a blood-borne infection was made. After talking with her attending physician, the resident counseled the mother that as the child had intact skin, it was very unlikely that any contagion had been passed from the razor blade to the child. The child also had an extra layer of protection as he had been immunized for tetanus and Hepatitis B. HIV and Hepatitis C were potential risks but felt to be very low given the circumstances. The mother was comfortable with this and said she would call if she saw any skin cuts that she hadn’t seen before.
Blood-borne infections are always a risk for anyone. Some occupations pose higher risks than others such as health care workers, emergency responders, public safety personnel, sex-trade workers and body art professionals. These workers can be exposed to body fluids by sharps, mucous membrane and skin exposures. Personal safety equipment and universal precautions should be utilized properly, consistently every time there is the possibility of an exposure. Accidental exposures still occur and the CDC has recommendations for proper management and possible post-exposure prophylaxic medication use. The main concerns are for Hepatitis B, Hepatitis C and human immunodeficiency virus (HIV).
HIV basically cannot survive outside the human body for long. The main transmission risk is from direct contact with infectious fluids. Drying of fluids dramatically decreases the infectivity. In laboratory studies with high concentrations of HIV, the amount of live virus was reduced to 90-99% after a few hours. The initial high concentrations were more than the usual concentration within a human body. Therefore, once the body fluid is dry, the risk of transmission is essentially zero.
One concern with medical needles is that the fluid within the hollow needle may not be dried, and therefore would contain live virus.
