Why environmental surveillance is essential

Leaders of organizations are confronted by a vast array of new and urgent questions.

  • How do we safely stay open?
  • Are our safety protocols effective?
  • Where are the high risk areas within our facilities?

With semi-vaccinated populations, varying mask mandates, and COVID-19 variants, organizations must implement layered strategies, including screening, masking, disinfection, ventilation, and environmental surveillance. Did you choose the right combination? Is it working? Monitoring pathogens in the air can help answer those questions.

The Thermo Scientific AerosolSense Sampler paired with PCR testing is designed to deliver timely and highly reliable insight into in-air pathogen presence, including Flu A/B, SARS-CoV-2, and/or RSV. The sampler acts right where you need it – in the air – sampling indoor air in classrooms, offices, nursing homes, hospitals, dormitories, and other indoor spaces. By sampling and PCR testing indoor air, you’re identifying SARS-CoV-2 right where it’s spread.

Why environmental surveillance is essential

The benefits

  • A fast and simple workflow: Results in less than 4 hours. Identify risks to help protect your organization in three steps.

  • Scalable: Validated for Flu A/B, SARS-CoV-2, and/or RSV B, the design is intended to capture a wide variety of in-air pathogens.
  • Paired with PCR testing: PCR is the industry gold standard for analyzing for the presence of pathogens and is highly accurate.

The impact

  • Early insight into pathogen presence for quick decision making
  • Identification of high risk areas
  • Complementary to individual screening programs
  • Open communication and visibility for increased confidence
  • Strengthened safety protocols
