Additional information relevant to use of precautions was added in the comments column to … (73) The risk of reinfection may be increased in the future with exposure to SARS-CoV-2 variant virus strains that are not neutralized by immune antisera, such as one recently described in South Africa. The guideline supersedes previous CDC recommendations for isolation precautions in hospitals. Larson D, Brodniak SL, Voegtly LJ, et al. Under these circumstances, repeat testing for SARS-CoV-2 or quarantine can be considered if a new exposure occurs more than 90 days after recovery from a prior infection. Seasonal coronavirus protective immunity is short-lasting. doi:10.1038/s41586-020-03041-6, Midgley CM, Kujawski SA, Wong KK, Collins, JP, Epstein L, Killerby ME, et al.

Wear disposable medical examination gloves or reusable utility gloves for cleaning the environment or medical equipment. 2021;12(1):267. Once the patient leaves, the room should remain vacant for the appropriate time, generally one hour, to allow for a full exchange of air, Instruct patients with a known or suspected airborne infection to wear a surgical mask and observe Respiratory Hygiene/Cough Etiquette. Wear gloves whenever touching the patient’s intact skin or surfaces and articles in close proximity to the patient (e.g., medical equipment, bed rails). Primary exposure to SARS-CoV-2 protects against reinfection in rhesus macaques. Identify resources for performing surveillance cultures, rapid diagnostic testing for viral and other selected pathogens, preparation of antimicrobial susceptibility summary reports, trend analysis, and molecular typing of clustered isolates (performed either on-site or in a reference laboratory) and use these resources according to facility-specific epidemiologic needs, in consultation with clinical microbiologists, Provide human and fiscal resources to meet occupational health needs related to infection control (e.g., healthcare personnel immunization, post-exposure evaluation and care, evaluation and management of healthcare personnel with communicable infections, In all areas where healthcare is delivered, provide supplies and equipment necessary for the consistent observance of Standard Precautions, including hand hygiene products and personal protective equipment (e.g., gloves, gowns, face and eye protection), Develop and implement policies and procedures to ensure that reusable patient care equipment is cleaned and reprocessed appropriately before use on another patient, Develop and implement processes to ensure oversight of infection control activities appropriate to the healthcare setting and assign responsibility for oversight of infection control activities to an individual or group within the healthcare organization that is knowledgeable about infection control, Develop and implement systems for early detection and management (e.g., use of appropriate infection control measures, including isolation precautions, personal protective equipment [PPE]) of potentially infectious persons at initial points of patient encounter in. Document competency initially and repeatedly, as appropriate, for the specific staff positions. Guideline for Isolation Precautions: Preventing Transmission of Infectious Agents in Healthcare Settings (2007) 6.

Review the efficacy of in-use disinfectants when evidence of continuing transmission of an infectious agent (e.g., rotavirus, In facilities that provide health care to pediatric patients or have, Include multi-use electronic equipment in policies and procedures for preventing contamination and for cleaning and disinfection, especially those items that are used by patients, those used during delivery of patient care, and mobile devices that are moved in and out of patient rooms frequently (e.g., daily). The edits do not constitute any change to the intent of the recommendations. (60) This guidance will be updated as additional evidence emerges regarding the reinfection risk that new variants may pose. Sci Rep. 2020;10(1):20048. 2020;2020.12.18.20248336. Isolation precautions. Considerations for Bioterrorist Threats, Table 4. (2020). If noncritical patient-care equipment (e.g., stethoscope) cannot remain in the home, clean and disinfect items before taking them from the home using a low- to intermediate-level disinfectant. Respiratory protection is recommended for all healthcare personnel, including those with a documented “take” after smallpox vaccination due to the risk of a genetically engineered virus against which the vaccine may not provide protection, or of exposure to a very large viral load (e.g., from high-risk aerosol-generating procedures, immunocompromised patients, hemorrhagic or flat smallpox, Administer measles vaccine to exposed susceptible persons within 72 hours after the exposure or administer immune globulin within six days of the exposure event for high-risk persons in whom vaccine is contraindicated. Similar to other human coronaviruses where studies have demonstrated reinfection, the probability of SARS-CoV-2 reinfection is expected to increase with time after recovery from initial infection because of waning immunity and the possibility of exposure to virus variants. Do not wear the same pair of gloves for the care of more than one patient. Consult infection control professionals before patient placement to determine the safety of alternative room that do not meet engineering requirements for an AIIR. Genomic evidence for reinfection with SARS-CoV-2: a case study. The guideline supersedes previous CDC recommendations for isolation precautions in hospitals. Resurgence of COVID-19 in Manaus, Brazil, despite high seroprevalence. Presymptomatic SARS-CoV-2 infections and transmission in a skilled nursing facility. Duration and key determinants of infectious virus shedding in hospitalized patients with coronavirus disease-2019 (COVID-19). EBioMedicine. (19,30) However, for SARS-CoV-2, reinfection appears to be uncommon during the initial 90 days after symptom onset of the preceding infection (Annex: Retesting and Quarantine of Adults Recovered from Laboratory-diagnosed SARS-CoV-2 Infection with Subsequent Re-Exposure). For current recommendations on face protection for measles, see Interim Infection Prevention and Control Recommendations for Measles in Healthcare Settings. Antibody tests for identification of current and past infection with SARS-CoV-2. Duration of isolation and precautions. Clin Infect Dis. One of the most important was the increased emphasis on decision making on the part of users. Use the following principles in developing this policy and procedures: The following recommendations apply to the use of needles, cannulas that replace needles, and, where applicable, intravenous delivery systems. Preprint. Nat Commun. SARS-CoV-2 infection protects against rechallenge in rhesus macaques. This interim guidance is based upon information available to date and will be updated as new information becomes available. Preprint. Findings from Investigation and Analysis of re-positive cases. Resende PC, Bezerra JF, de Vasconcelos RHT, et al. 2020;ciaa1451. Robust SARS-CoV-2-specific T-cell immunity is maintained at 6 months following primary infection. Wear gloves with fit and durability appropriate to the task. Rapid generation of durable B cell memory to SARS-CoV-2 spike and nucleocapsid proteins in COVID-19 and convalescence. For most persons with COVID-19 illness, isolation and precautions can generally be discontinued 10 days after symptom onset 1 and resolution of fever for at least 24 hours, without the use of fever-reducing medications, and with improvement of other symptoms. Routine donning of gowns upon entrance into a high risk unit (e.g., ICU, NICU, HSCT unit) is not indicated, Use PPE to protect the mucous membranes of the eyes, nose and mouth during procedures and patient-care activities that are likely to generate splashes or sprays of blood, body fluids, secretions and excretions. Clin Infect Dis. Studies have not found evidence that clinically recovered adults with persistence of viral RNA have transmitted SARS-CoV-2 to others.
