Interim U.S. Steerage for Danger Evaluation and Work Restrictions for Healthcare Personnel with Potential Publicity to COVID-19
This interim steerage is meant to help with evaluation of danger and utility of labor restrictions for asymptomatic healthcare personnel (HCP) with potential publicity to sufferers, guests, or different HCP with confirmed COVID-19. Separate steerage is offered for travel- and community-related exposures. The community-related publicity steerage can be utilized to tell danger evaluation for sufferers and guests uncovered to SARS-CoV-2 in a healthcare setting. CDC has additionally launched steerage about return to work standards for HCP with COVID-19 and methods for mitigating HCP staffing shortages.
Due to their usually intensive and shut contact with weak people in healthcare settings, a conservative strategy to HCP monitoring and making use of work restrictions is beneficial to stop transmission from probably contagious HCP to sufferers, different HCP, and guests. Occupational well being applications ought to have a low threshold for evaluating signs and testing HCP.
The feasibility and utility of performing contact tracing of uncovered HCP and utility of labor restrictions relies upon upon the diploma of neighborhood transmission of SARS-CoV-2 and the assets obtainable for contact tracing. For areas with:
- Minimal to no neighborhood transmission of SARS-CoV-2, enough assets for contact tracing, and no staffing shortages, danger evaluation of uncovered HCP and utility of labor restrictions could also be possible and efficient.
- Reasonable to substantial neighborhood transmission of SARS-CoV-2, inadequate assets for contact tracing, or staffing shortages, danger evaluation of uncovered HCP and utility of labor restrictions is probably not doable.
This steerage relies on presently obtainable knowledge about COVID-19. Suggestions concerning which HCP are restricted from work may not anticipate each potential state of affairs and can change if indicated by new info. Occupational well being applications ought to use scientific judgement in addition to the ideas outlined on this steerage to assign danger and decide the necessity for work restrictions. This strategy may be refined and up to date, together with defining the position of testing uncovered HCP as extra info turns into obtainable and as response wants change in the US.
Evolution of At present Advisable HCP Evaluation Steerage
CDC’s suggestions for the evaluation of and response to HCP exposures to SARS-CoV-2-infected sufferers have developed because the incidence of COVID-19 in the US has modified. Earlier than acknowledged widespread transmission in the US, CDC beneficial an aggressive strategy to figuring out uncovered HCP and included suggestions for limiting some HCP from work who had greater danger exposures. As neighborhood unfold of COVID-19 turned obvious in lots of areas and as transmission from asymptomatic people was acknowledged, this strategy turned impractical and diverted assets away from different essential an infection prevention and management features. In response, CDC suggested amenities to think about forgoing formal contact tracing and work restrictions for HCP with exposures in favor of universally utilized symptom screening and supply management methods.
This up to date steerage describes a course of for resumption of contact tracing and utility of labor restrictions that may be thought of in areas the place unfold in the neighborhood has decreased and when capability exists to carry out these actions with out compromising different essential an infection prevention and management features. It has been simplified to give attention to exposures which might be believed to lead to greater danger for HCP (e.g., extended publicity to sufferers with COVID-19 when HCP’s eyes, nostril, or mouth should not coated). Different exposures not included as greater danger, together with having physique contact with the affected person (e.g., rolling the affected person) with out robe or gloves, could impart some danger for transmission, significantly if hand hygiene isn’t carried out and HCP then contact their eyes, nostril, or mouth. The precise components related to these exposures ought to be evaluated on a case by case foundation; interventions, together with restriction from work, could be utilized if the chance for transmission is deemed substantial.
The definition of “extended” was prolonged to check with a time interval of 15 or extra minutes, which aligns with the time interval used within the steerage for neighborhood exposures and contact tracingpdf icon. Nonetheless, any period ought to be thought of extended if the publicity happens throughout efficiency of an aerosol-generating process.1
Steerage for Asymptomatic HCP Who Have been Uncovered to People with Confirmed COVID-19
Increased-risk exposures typically contain publicity of HCP’s eyes, nostril, or mouth to materials probably containing SARS-CoV-2, significantly if these HCP have been current within the room for an aerosol-generating process.
This steerage applies to HCP with potential publicity in a healthcare setting to sufferers, guests, or different HCP with confirmed COVID-19. Exposures can even happen from a suspected case of COVID-19 or from an individual beneath investigation (PUI) when testing has not but occurred or if outcomes are pending. Work restrictions described on this steerage may be utilized to HCP uncovered to a PUI if check outcomes for the PUI should not anticipated to return inside 48 to 72 hours. Due to this fact, a document of HCP uncovered to PUIs ought to be maintained. If check outcomes shall be delayed greater than 72 hours or the affected person is constructive for COVID-19, then the work restrictions described on this doc ought to be utilized.

- Information are inadequate to exactly outline the period of time that constitutes a protracted publicity. Till extra is understood about transmission dangers, it’s cheap to think about an publicity of 15 minutes or extra as extended. Nonetheless, any period ought to be thought of extended if the publicity occurred throughout efficiency of an aerosol producing process.
- Information are restricted for the definition of shut contact. For this steerage it’s outlined as: a) being inside 6 ft of an individual with confirmed COVID-19 or b) having unprotected direct contact with infectious secretions or excretions of the individual with confirmed COVID-19.
- Figuring out the time interval when the affected person, customer, or HCP with confirmed COVID-19 may have been infectious:
- For people with confirmed COVID-19 who developed signs, take into account the publicity window to be 2 days earlier than symptom onset via the time interval when the person meets standards for discontinuation of Transmission-Based mostly Precautions
- For people with confirmed COVID-19 who by no means developed signs, figuring out the infectious interval could be difficult. In these conditions, accumulating details about when the asymptomatic particular person with COVID-19 could have been uncovered may assist inform the interval once they have been infectious.
- Normally, people with COVID-19 ought to be thought of probably infectious starting 2 days after their publicity till they meet standards for discontinuing Transmission-Based mostly Precautions.
- If the date of publicity can’t be decided, though the infectious interval may very well be longer, it’s cheap to make use of a place to begin of 2 dayspdf icon previous to the constructive check via the time interval when the person meets standards for discontinuation of Transmission-Based mostly Precautions for contact tracing.
- Whereas respirators confer the next degree of safety than facemasks and are beneficial when caring for sufferers with COVID-19, facemasks nonetheless confer some degree of safety to HCP, which was factored into this danger evaluation. Fabric face coverings should not thought of PPE as a result of their functionality to guard HCP is unknown.
- If staffing shortages happen, it may not be doable to exclude uncovered HCP from work. For added info and issues check with Methods to Mitigating HCP Staffing Shortages.
- *For the aim of this steerage, fever is outlined as subjective fever (feeling feverish) or a measured temperature of 100.0oF (37.8oC) or greater. Observe that fever could also be intermittent or is probably not current in some individuals, comparable to those that are aged, immunocompromised, or taking sure fever-reducing drugs (e.g., nonsteroidal anti-inflammatory medication [NSAIDS]).
