The duration and robustness of immunity to SARS-CoV-2 remains under investigation. Linking to a non-federal website does not constitute an endorsement by CDC or any of its employees of the sponsors or the information and products presented on the website. However, available evidence suggests that most recovered adults would have a degree of immunity for at least 90 days following initial diagnosis of laboratory-confirmed COVID-19. Components of a Protective Environment, Figure. Remove and dispose of contaminated PPE and perform hand hygiene prior to transporting patients on Contact Precautions. The preferred method of hand decontamination is with an alcohol-based hand rub. * Symptom onset is defined as the date on which symptoms first began, including non-respiratory symptoms. Despite millions of SARS-CoV-2 infections worldwide, including the United States, to date, surveillance and investigations have thus far demonstrated few confirmed cases of reinfection. Discontinue Contact Precautions after signs and symptoms of the infection have resolved or according to pathogen-specific recommendations in Appendix A. Avoid placing patients on Droplet Precautions in the same room with patients who have conditions that may increase the risk of adverse outcome from infection or that may facilitate transmission (e.g., those who are immunocompromised, have or have anticipated prolonged lengths of stay). The CDC rates isolation necessity with a Categorization Scheme for Recommendations that looks like this: Category IA: Strongly recommended for isolation based on evidence from clinical, experimental, or epidemiologic tests.

Discontinue Airborne Precautions according to pathogen-specific recommendations in Appendix A. CDC recommends that all people, regardless of symptoms, and regardless of whether or not they have had laboratory-confirmed COVID-19 in the past, continue to use all recommended prevention strategies to prevent SARS-CoV-2 transmission (e.g., wear masks, stay at least 6 feet away from others who do not live with you, avoid crowds, and wash hands regularly).
