Return to Work Strategy

Persons infected with Coronavirus are likely contagious before symptoms develop.  In fact many never develop symptoms and may still pass the virus on to others.

Knowing this, how can we plan a return to work strategy?

I have suggested a 3 step approach outlined in this post.  It consists of at home symptom checking on a smart device, temperature screening at point of entry to facilities, and antibody testing to detect those who may be asymptomatic but have IgM antibodies, indicating recent infection and should be isolated, or those with IgG antibody who may be immune.

Of course there also need to be environmental controls and procedures for sanitizing, hand washing, social distancing within workspaces.


Temperature Screening for Return to Work, School and Entry to Any Business

Some organizations have on staff or have hired medical personnel in full PPE gear to perform temperature screening using hand held “no touch” devices.

Although these devices are relatively inexpensive, the medical staff is not, and may be prohibitive for many companies.

If using these devices, quality and accuracy are going to be key, we’ll post these here when we find them available (affiliate links.)


Telethermographic Systems

More elegant temperature screening solutions include the use of “telethermographic systems.”

These are “smart” or AI software assisted cameras or imaging devices that rapidly screen large numbers of people at entrances to facilities.

The FDA has issued guidance encouraging the use of these devices during the Coronavirus epidemic:

Fever is a common symptom of COVID-19, typically appearing 2-14 days after exposure. Telethermographic systems are able to determine surface skin temperature, which is then used to estimate the temperature at a reference body site (e.g., oral, tympanic membrane). The advantage of using telethermographic systems for initial temperature assessment for triage use is the potential use in high throughput areas (e.g., airports, businesses, warehouses, factories) and in settings where other temperature assessment products may be in short supply. The available scientific literature supports the use of telethermographic systems in the context of initial human temperature measurement during such a triage process.  Additionally, international standards and scientific literature have described guidelines for using telethermographic systems for initial temperature assessment for triage use and best practices for standardized performance testing of such products.
