Monitoring the presence and infection risk of Covid-19 and Norovirus

Benefits of Surface Testing Covid-19 and Norovirus

Virus outbreaks can be costly, time consuming and limit the operational ability of a business. In addition, they can endanger vulnerable people. Testing is vital:

  • Prevent virus outbreaks by monitoring presence of the SARS-CoV-2 and Norovirus
  • Limit and minimise the spread during an outbreak

Individual testing using nostril swabs is costly, time consuming and in some settings might be difficult or impossible (especially in care and nursing homes) –> Surface Swabbing is an efficient and effective alternative.

Scientists found that SARS-CoV-2, the virus that causes COVID-19, can be detected on plastic and stainless steel surfaces for up to three days and on cardboard for up to 24 hours*. Evidence suggests that it is possible to contract the virus by touching a contaminated surface or object and then touching the face*.

Environmental or surface swabbing can be an efficient and cheaper alternative which is easy to implement for fast testing:

  • Results available within 24 hours after the swab is received in the laboratory
  • Testing before and after cleaning ensures that disinfection routines are working
  • Surface areas can be tested easily, up to 1m² (=large surface area), which can be multiple locations, like door handles, high traffic areas, desks etc
  • Individual nostril swabs may not always be carried out correctly
  • Presence of the virus on surfaces can also be an indicator for the presence in the air (where transmission is much more likely)

Use surface testing to prevent virus from spreading – Analysis by an accredited laboratory – results available within 24 hours after receipt of swab sample:

Suitable for a wide range of environments, including offices, factories, public transport and health care, nursing homes with the ability to test such surfaces as door/grab handles, light switches, HVAC vents, table/desk tops, office equipment, control panels, seat backs, sinks cabinets, tables, walls, machinery, equipment and floors and toilet cubicles. A sterile swab is rubbed over the surface to collect viable samples of viruses present.
