Primary Prevention

Exposure Control

There is currently no vaccine to prevent 2019-nCoV infection. The best way to prevent infection is to avoid being exposed to this virus. However, as a reminder, CDC always recommends everyday preventive actions to help prevent the spread of respiratory viruses, including:

Wash your hands often with soap and water for at least 20 seconds. Use an alcohol-based hand sanitizer that contains at least 60% alcohol if soap and water are not available. Avoid touching your eyes, nose, and mouth with unwashed hands. Avoid close contact with people who are sick. Stay home when you are sick. Cover your cough or sneeze with a tissue, then throw the tissue in the trash. Clean and disinfect frequently touched objects and surfaces.

• Protective Clothing
  • Lab coats, gloves when direct skin contact with infected materials or animals is unavoidable.
  • Eye protection must be used where there is a known or potential risk of exposure to splashes.
• Miscellaneous
  • All procedures that may produce aerosols, or involve high concentrations or large volumes should be conducted in a biological safety cabinet (BSC).
  • The use of needles, syringes, and other sharp objects should be strictly limited. Additional precautions should be considered with work involving animals or large scale activities.

Handling and Storage

• Spills
  • Allow aerosols to settle and, wearing protective clothing, gently cover spill with paper towels and apply an appropriate disinfectant, starting at the perimeter and working towards the center.
  • Allow sufficient contact time before clean up.
• Disposal
  • Decontaminate all wastes that contain or have come in contact with the infectious organism before disposing by autoclave, chemical disinfection, gamma irradiation, or incineration.
• Storage
  • The infectious agent should be stored in leak-proof containers that are appropriately labeled.
