For patients with mild to moderate COVID-19, replication-competent virus has not been recovered after 10 days following symptom onset (CDC, unpublished data, 2020; Wölfel et al., 2020; Arons et al., 2020; Bullard et al., 2020; Lu et al., 2020; personal communication with Young et al., 2020; Korea CDC, 2020). [cited 2020 Sep 12]; Available from: https://academic.oup.com/cid/advance-article/doi/10.1093/cid/ciaa1330/5901661. Investigators found no evidence of active infection in these re-exposed persons: no new SARS-CoV-2 infections were attributable to the contacts of these persons during a 14-day quarantine period, and none of the specimens collected from these persons yielded replication competent virus. The likelihood of recovering replication-competent virus also declines after onset of symptoms. To date, reports of reinfection have been infrequent. If you are a healthcare professional who thinks or knows you had COVID-19, you should follow the same recommendations listed above for when you can resume being around others outside the workplace. Saving Lives, Protecting People Centers for Disease Control and Prevention.

Rochester, NY: Social Science Research Network; 2020 Aug [cited 2020 Sep 12]. This update incorporates recent evidence to inform the duration of isolation and precautions recommended to prevent transmission of SARS-CoV-2 to others, while limiting unnecessary prolonged isolation and unnecessary use of laboratory testing resources. Specifically, the utility of serologic testing to establish the absence or presence of infection or reinfection remains undefined. Although replication-competent virus was not isolated 3 weeks after symptom onset, recovered patients can continue to have SARS-CoV-2 RNA detected in their upper respiratory specimens for up to 12 weeks (Korea CDC, 2020; Li et al., 2020; Xiao et al, 2020).

Zou L, Ruan F, Huang M, Liang L, Huang H, Hong Z. 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. These persons should follow the guidance below for “I was severely ill with COVID-19 or have a severely weakened immune system (immunocompromised) due to a health condition or medication. Isho B, Abe KT, Zuo M, Jamal AJ, Rathod B, Wang JH, et al. 2020 Oct;99:229–30. 2020. A large contact tracing study demonstrated that high-risk household and hospital contacts did not develop infection if their exposure to a case patient started 6 days or more after the case patient’s illness onset (Cheng et al., 2020). When Can I Be with Others? Some studies have also noted lower titers and faster waning of anti-SARS-CoV-2 antibodies in mild or asymptomatic cases of COVID-19 (Long et al; Seow et al; Ibrrando et al). Based on what we know from other related human coronaviruses, people appear to become susceptible to reinfection around 90 days after onset of infection. When you can be around others depends on different factors for different situations. bioRxiv. Immunological and Viral Correlates of COVID-19 Disease Severity: A Prospective Cohort Study of the First 100 Patients in Singapore. The etiology of this persistently detectable SARS-CoV-2 RNA has yet to be determined. Quarantine is used to keep someone who might have been exposed to COVID-19 away from others.Quarantine helps prevent spread of disease that can occur before a person knows they are sick or if they are infected with the virus without feeling symptoms. However, additional reports suggest that reinfection is possible as early as 45 days after illness onset or diagnosis of the preceding infection (Abu-Raddad et al; Larson et al; Tillet et al). The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. Cell [Internet]. The CDC … Risk of reinfection depends on the likelihood of re-exposure to infectious cases of COVID-19. Clinical, immunological and virological characterization of COVID-19 patients that test re-positive for SARS-CoV-2 by RT-PCR. In the absence of clinical evaluation to rule out SARS-CoV-2 reinfection, this person should be isolated for the duration recommended in the memo above – for most persons, this would be 10 days after symptom onset and resolution of fever for at least 24 hours, without the use of fever-reducing medications, and with improvement of other symptoms. [1] Symptom onset is defined as the date on which symptoms first began, including non-respiratory symptoms. These findings strengthen the justification for relying on a symptom based, rather than test-based strategy for ending isolation of these patients, so that persons who are by current evidence no longer infectious are not kept unnecessarily isolated and excluded from work or other responsibilities. However, available evidence suggests that most recovered individuals would have a degree of immunity for at least 3 months following initial diagnosis of COVID-19. Humoral immune response and prolonged PCR positivity in a cohort of 1343 SARS-CoV 2 patients in the New York City region. 2020 Aug 14 [cited 2020 Sep 12]; Available from: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7427556/. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. Added criteria and evidence to address whether people who recovered from COVID-19 and are re-exposed to COVID-19 need to undergo repeat quarantine. This includes, but is not limited to, at home, in a hotel or dormitory room, or in a group isolation facility. 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 due to waning immunity and possibly genetic drift. If you have or think you might have COVID-19, it is important to stay home and away from other people. The Centers for Disease Control and Prevention (CDC) is set to shorten the recommended length of quarantine after exposure to someone who is positive for … Separating people… People who are in isolation should stay home until it’s safe for them to be around others. New research indicates that COVID-19 patients are most infectious between two days before the onset of symptoms and five days after symptoms start. 2020 Sep 10;383(11):1085–7. Of course, social isolation and loneliness can become more common with age.And the arrival of the novel coronavirus will almost certainly make the problem worse. This evidence must be interpreted cautiously as anti-SARS-CoV-2 antibodies have not been definitively correlated with protection of humans from infection. Centers for Disease Control and Prevention.

Humoral Immune Response to SARS-CoV-2 in Iceland. *Loss of taste and smell may persist for weeks or months after recovery and need not delay the end of isolation. At home, anyone sick or infected should separate from others, stayh in a specific “sick room” or area, and use a separate bathroom (if available). Clinical and immunological assessment of asymptomatic SARS-CoV-2 infections. Int J Infect Dis. If a person has a new exposure to someone with suspected or confirmed COVID-19 and meets all of the following criteria: then that person does not require quarantine or repeat testing for SARS-CoV-2 in the context of this new exposure. Most people do not require testing to decide when they can be around others; however, if your healthcare provider recommends testing, they will let you know when you can resume being around others based on your test results. Symptomatic SARS-CoV-2 reinfection by a phylogenetically distinct strain. May 19, 2020. The Centers for Disease Control revised its guidelines for coronavirus, saying people with mild to moderate illness only need to complete 10 days of isolation. The current evidence includes the following caveats: Available data indicate that persons with mild to moderate COVID-19 remain infectious no longer than 10 days after symptom onset. Assessment of the risk of SARS-CoV-2 reinfection in an intense re-exposure setting. For persons previously diagnosed with symptomatic COVID-19 who remain asymptomatic after recovery, retesting is not recommended within 3 months after the date of symptom onset for the initial COVID-19 infection. When can I be Around Others? As the COVID-19 pandemic continues, we expect to see more cases of reinfection. Clin Infect Dis [Internet]. New England Journal of Medicine.

Talk to your healthcare provider for more information. Specimens from patients who recovered from an initial COVID-19 illness and subsequently developed new symptoms and retested positive by RT-PCR did not have replication-competent virus detected (Korea CDC, 2020; Lu et al., 2020). An increasing number of published studies suggest that >90% of recovered COVID-19 patients develop anti-SARS-CoV-2 antibodies (Wajnberg cohort of 1343; Gudbjartsson et al; Deeks et al; Iyer et al). If reinfection is confirmed or remains suspected they should remain under the recommended SARS-CoV-2 isolation until they meet the criteria for discontinuation of precautions – for most persons, this would be 10 days after symptom onset and resolution of fever for at least 24 hours, without the use of fever-reducing medications, and with improvement of other symptoms. Currently, it is unknown if recovered persons are definitively immune to SARS-CoV-2 re-infection because biologic markers of immunity have not been correlated with protection from infection in humans. For persons who never develop symptoms, isolation and other precautions can be discontinued 10 days. 2020. Animal challenge studies of SARS-CoV-2 (Deng et al; Chandrashekar et al) and an investigation of seropositive persons in a high transmission setting (Addetia et al) provide initial evidence of protection against re-infection after prior infection with SARS-CoV-2. Human Coronavirus NL63 Molecular Epidemiology and Evolutionary Patterns in Rural Coastal Kenya. Persons being evaluated for reinfection with SARS-CoV-2 should be isolated under recommended precautions while undergoing evaluation. To reduce introduction and spread of new variants of SARS-CoV-2, CDC issued an Order effective January 26, 2021. 2020 Jul 11;2020.07.09.20148429. Science. Healthcare providers and public health officials managing persons with coronavirus disease 2019 (COVID-19) under isolation who are not in healthcare settings. If implemented with current safety measures to prevent SARS-CoV-2 transmission (i.e., wear masks, stay 6 feet away from others whenever possible, and wash hands regularly), the risks of potential SARS-CoV-2 transmission from recovered persons are at this time likely outweighed by the personal and societal benefits of avoiding unnecessary quarantine. Search. Deng W, Bao L, Liu J, Xiao C, Liu J, Xue J, et al. Coronavirus disease (COVID-19), which is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was first identified in December 2019 in Wuhan, China, and has since spread rapidly, evolving into a full-blown pandemic. Ibarrondo FJ, Fulcher JA, Goodman-Meza D, Elliott J, Hofmann C, Hausner MA, et al. Correlates of immunity to SARS-CoV-2 infection have not been established. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. It is important to note that plasma antibodies are only one component of human immunity and that immunity may be achieved through other mechanisms such as virus-specific memory T cells (Cervia et al; Kaneko et al; Rodda et al; Sekine et al). For most persons with COVID-19 illness, isolation and precautions can generally be discontinued 10 days after symptom onset1 and resolution of fever for at least 24 hours, without the use of fever-reducing medications, and with improvement of other symptoms. Recovered persons can continue to shed detectable SARS-CoV-2 RNA in upper respiratory specimens for up to 3 months after illness onset, albeit at concentrations considerably lower than during illness, in ranges where replication-competent virus has not been reliably recovered and infectiousness is unlikely. © Provided by BGR Coronavirus Quarantine CDC Director Dr. Robert Redfield told Mike Pence and the White House Coronavirus Task Force that … However, there could be scenarios in which the risk of re-infection and potential transmission may be deemed high enough to warrant quarantine of the exposed individual who has recovered from confirmed SARS-CoV-2 infection in the past 3 months. including three recovered persons who were intensively re-exposed to COVID-19 in a high transmission setting but were not re-infected (Addetia et al.). Your doctor may work with an infectious disease expert or your local health department to determine whether testing will be necessary before you can be around others. medRxiv. Specifically, Korea CDC conducted an epidemiologic and virologic investigation of persons who tested positive after having clinically recovered and having two negative PCR tests, 170 of whom were exposed to an infectious case of COVID-19. In July the agency shortened, from 14 days to 10, its advice on how long a person should stay in isolation after they first experience … 13 Jan EARLY RELEASE: COVID-19 Trends Among Persons Aged 0-24 Years - United States, March 1-December 12, 2020; 13 Jan Cases in the U.S. 13 Jan COVID-19 Vaccination; 13 Jan Requirement for Proof of Negative COVID-19 Test or Recovery from COVID-19 for All Air Passengers Arriving in the United States; 13 Jan US COVID-19 Cases Caused by Variants The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website.

Seow J, Graham C, Merrick B, Acors S, Steel KJA, Hemmings O, et al. In one case report, a person with mild illness provided specimens that yielded replication-competent virus for up to 18 days after symptom onset (Liu et al., 2020). Investigation of 285 “persistently positive” persons, which included 126 persons who had developed recurrent symptoms, found no secondary infections among 790 contacts attributable to contact with these case patients. 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. For persons who never developed symptoms, the date of first positive viral diagnostic test (PCR or antigen) for SARS-CoV-2 RNA should be used in place of the date of symptom onset. [2] PCR testing is defined as the use of an RT-PCR assay to detect the presence of SARS-CoV-2 RNA.. Persons recovered from COVID-19 who have been re-exposed to an active case have not been demonstrated infectious to others. Sekine T, Perez-Potti A, Rivera-Ballesteros O, Strålin K, Gorin J-B, Olsson A, et al. 2020 Sep 1;0(0):null. Evidence does not indicate the definitive absence of re-infection during this period, only that risks of potential SARS-CoV-2 transmission from recovered persons are likely outweighed by the personal and societal benefits of avoiding unnecessary quarantine. Liu WD, Chang SY, Wang JT, Tsai MJ, Hung CC, Hsu CL, Lu J, Peng J, Xiong Q, Liu Z, Lin H, Tan X, et al. People who are severely ill with COVID-19 might need to stay home longer than 10 days and up to 20 days after symptoms first appeared. These studies also provided limited evidence linking antibody presence to protection against re-infection. Cases of reinfection of COVID-19 have been reported but are rare. Rodda LB, Netland J, Shehata L, Pruner KB, Morawski PM, Thouvenel C, et al.

More than a year into the coronavirus disease 2019 (COVID-19) pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS … It also does away with the requirement that coronavirus patients get a negative test results before leaving isolation. 2020;26(8):1200–4. 2020 Aug 26;2020.08.24.20179457. Self-isolation means that you need to separate yourself from others because you either 1) you are infected with the COVID-19 virus and you had a positive COVID-19 test; or, 2) you are probably infected because you are a close contact of a confirmed case and have symptoms, although you have not been tested. Additional reports of recovered persons have found no evidence of COVID-19 in those who develop symptoms of influenza-like or other illness within 90 days of recovery (Mumoli et al.) The risk of reinfection may be lower in the first 3 months after initial infection, based on limited evidence from another betacoronavirus (HCoV-OC43), the genus to which SARS-CoV-2 belongs (Kiyuka et al, 2018). Note that these recommendations do not apply to persons with severe COVID-19 or with severely weakened immune systems (immunocompromised). Efforts to isolate replication-competent virus from 108 of these case patients were unsuccessful (Korea CDC, 2020). CDC updates coronavirus guidelines on isolation, testing Most people can stop isolation 10 days after COVID-19 symptom onset For all others, a test-based strategy is no longer recommended except to discontinue isolation or precautions earlier than would occur under the strategy outlined in Part 1, above. Abu-Raddad LJ, Chemaitelly H, Ayoub HH, Kanaani ZA, Khal AA, Kuwari EA, et al. Longitudinal evaluation and decline of antibody responses in SARS-CoV-2 infection.
