Area of Science:

  • Virology
  • Dermatology
  • Laser Medicine

Background:

  • Carbon dioxide (CO2) lasers are used in surgery.
  • Concerns exist regarding disease transmission via laser-generated plume (aerosol).
  • Bovine papillomavirus causes skin lesions.

Purpose of the Study:

  • To determine if CO2 laser plume can transmit disease.
  • To evaluate the risk of viral transmission from infected tissue treated with a CO2 laser.

Main Methods:

  • Bovine papillomavirus-induced fibropapillomas were treated with a CO2 laser.
  • Laser plume was collected and applied to the skin of calves.
  • Tumor development and viral presence were analyzed.

Main Results:

Related Experiment Videos

  • Papillomavirus DNA was detected in the laser plume across all tested settings.
  • Tumors developed in calves inoculated with the laser plume.
  • Histological and biochemical analyses confirmed viral infection.

Conclusions:

  • Laser plume can transmit disease, specifically bovine papillomavirus.
  • Practitioners must exercise caution when using lasers on viral lesions to prevent disease transmission.
