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. Correlates of immunity to SARS-CoV-2 infection have not been established. 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 … Zou L, Ruan F, Huang M, Liang L, Huang H, Hong Z. Efforts to isolate replication-competent virus from 108 of these case patients were unsuccessful (Korea CDC, 2020). 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. It’s unclear whether the CDC will change its recommendations for isolation, which is meant for people confirmed to have covid-19. Your healthcare provider will let you know if you can resume being around other people based on the results of your testing.

Long Q-X, Tang X-J, Shi Q-L, Li Q, Deng H-J, Yuan J, et al. Recovery of replication-competent virus between 10 and 20 days after symptom onset has been documented in some persons with severe COVID-19 that, in some cases, was complicated by immunocompromised state (van Kampen et al., 2020). For persons who develop new symptoms consistent with COVID-19 during the 3 months after the date of initial symptom onset, if an alternative etiology cannot be identified by a provider, then the person may warrant retesting. (Preprint) Medrxiv. Studies have not found evidence that clinically recovered persons with persistence of viral RNA have transmitted SARS-CoV-2 to others. Deng W, Bao L, Liu J, Xiao C, Liu J, Xue J, et al. 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. 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. 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. 2020 Aug 14 [cited 2020 Sep 12]; Available from: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7427556/.

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. Several fluid-resistant and impermeable protective clothing options are available in the marketplace for HCP. Nat Med.

Int J Infect Dis. 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). 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). Thus, for persons recovered from SARS-CoV-2 infection, a positive PCR without new symptoms during the 90 days after illness onset more likely represents persistent shedding of viral RNA than reinfection.
