Nov 12 ; 20 If you tested positive for COVID with a viral test within the previous 90 days and subsequently recovered and remain without COVID symptoms, you do not need to quarantine or get tested after close contact. However, because guidelijes prolonged isolation for the one-size-fits-all approach was influenced by infectiousness threshold values, the difference between the one-size-fits-all and personalized approaches in prolonged isolation became smaller with higher infectiousness threshold values.

May 19, The viral load data measured in upper respiratory specimens were used for the analysis.
Eight cases reported from China and one case reported from Germany were excluded because their viral load was above the detection limit only two times or fewer. Five cases who received lopinavir-ritonavir treatment and one case with less than two data points from Singapore were excluded. Seven cases from Korea were excluded because they were under lopinavir-ritonavir treatment. SARS-CoV-2 viral dynamics without antiviral treatment is described by a mathematical model previously proposed and applied in Ikeda et al.
The original three-dimensional system Equation is reduced to the following two-dimensional system:. Note that f t is a monotonically decreasing function. A model considering an eclipse phase of infection, which slows viral growth, has been used to describe the virus dynamics of SARS-CoV-2 and other viruses Baccam et al. This model is driven by the following system of differential equations:. To decrease the number of parameters to be estimated, parameters f I 0 and k were fixed at 0. A model considering an innate immune response e. The model is regulated by the following system of differential equations:.
A nonlinear mixed-effect model was used to fit the model to the longitudinal viral load data. A mixed model was used Best et al. Both a fixed effect same among individuals and a random effect different between individuals in each parameter are considered. To account yuidelines the left-censoring problem i. We randomly resampled the parameter set i. We assumed cdc guidelines for isolating covid patients due load obtained by running the model over time, V tis true or expected viral load. However, the viral load quantified by the PCR click the following article is influenced by a measurement error.
We assumed the error is independent and identically distributed i. Although the interval of tests and the consecutive negative results necessary to end isolation can vary, for the purpose of illustration in the following explanation, we assumed that the guidelinex were performed every day and that two consecutive negative results were necessary. Negative results correspond to the measured viral load below an infectiousness threshold value gray dots circled in blue in Figure 6. Then, we computed the probability that true viral load is above the detection limit when the second consecutive negative result is obtained:. In the upper panel in Figure 6the true viral load is below the detection limit when the second consecutive negative result is observed.

In the interests of transparency, eLife publishes visit web page most substantive revision requests and the accompanying author responses. This paper uses a simulation approach to demonstrate that a personalized viral load based testing approach has the potential to limit the duration of unnecessary isolation among infected cdc guidelines for isolating covid patients due while not increasing the risk of releasing an infectious person.
This work could influence policies regarding duration of isolation is hospitals and at home. Thank you for crc your article "Revisiting the guidelines for ending isolation for COVID patients" for consideration by eLife. Your article has been reviewed by 2 peer reviewers, including Joshua T Schiffer as the Reviewing Editor and Reviewer 1, and the evaluation isolatibg been overseen by a Senior Editor. As is customary in eLifethe reviewers have discussed their critiques with one another and with the editors. What follows below is the Reviewing Editor's edited compilation of the going like kissing wild feels how and ancillary points provided by reviewers in their critiques and in their interaction post-review.
Please submit a revised version that addresses these concerns directly. Please also discuss more specifically how different countries around the world are differing in terms of cdc guidelines for isolating covid patients due policies. A brief review of national practices that incorporate one strategy or the other to inform the reader of the current standard would be helpful to highlight the importance of the work. These are far less expensive, have far less turnaround and are now widely used in many countries. Antigen tests should be contextualized given the results of this modeling. Saliva testing is also widespread in many places. Modeling of both approaches is available in the literature and should be cited. These models should be discussed and in particular it should be mentioned whether their slightly different structures could alter the paper's conclusions.
Similarly, a couple of research groups have made estimates of fog load thresholds required for transmission and these should be referenced as well. The authors should acknowledge that confidence intervals reported in the paper are quite speculative in the sense that the extent and quality of relevant viral load data for intra-host modeling is unfortunately quite limited. If the model is misclassified based on non-representative input data, then estimations ude duration of isolation could be biased. Can this only occur after development of symptoms or after a certain number of days of infection?
This section of the methods should provide more detail. Jeong et al. Two types of guidelines are commonly used: 1 A fixed duration 10 days or 2 weeks of isolation following the development of symptoms, which the authors call 'one-size-fits-all'. In the former, a long duration would lead to unnecessarily long isolation periods, whereas a short duration may end up releasing individuals still able to transmit cdc guidelines for isolating covid patients due disease. The latter avoids these pitfalls, but requires multiple tests, increasing costs and the burden on healthcare staff. To identify which of these strategies is better, the authors develop a mathematical model of within-host SARS-CoV-2 dynamics and apply it to data of viral load changes post infection from untreated patients.
Using the parameters estimated, they create a pool of virtual patients and simulate dynamics in these patients and assess the consequences of the two isolation ending approaches by calculating the probability that a patient released is still able to transmit and the excess or unwarranted duration of isolation. They find that in general the personalized approach fares better on both metrics. The conceptual approach developed why kissing is important a relationship novel and is also likely to be applicable beyond the current pandemic.
The application of the approach and the resulting inferences drawn, however, need stronger justification. My reasons are below. This error is estimated in the study as the variance of the normal distribution fit to the residuals of the best-fits of the mathematical model to the patient data of viral load changes see lines and The error is thus strongly dependent on the model. One could use a model with more parameters and obtain a 'better' fit to the data, with smaller residuals, which could then presumably change the inferences above. Indeed, many other models have been developed to describe SARS-CoV-2 dynamics and have been applied to some of the datasets the present study has used.
The required durations of isolation may then be even shorter than predicted. Would guidelines that account for this heterogeneity in disease severity be easier to implement? In other words, individuals could be categorized into disease severity classes say asymptomatic, mild, moderate, or severe and have fixed but different durations of isolation for each class. For personalized treatments, one could still use these categories to decide when to start measurements. In the present study, when to start measurements in the personalized approach is not mentioned and it appears that measurements are assumed to be made daily from the time of isolation, which may be unnecessary and impractical. If at an epidemiologically identified threshold, the difference between the two approaches is small, the fixed duration approach may have the advantage of simplicity and of doing away with additional tests.
One way to address comment 1 above could be to compare alternative models and identify the best model based on estimates of AIC, or other such metrics, and use it to estimate the measurement error. The authors should show fits of the model to the data and list the model parameter values estimated; this would help appreciate the inferences drawn better. We thank how to prepare lip scrub at homeowners club editors and reviewers for this comment and fully agree about the importance of these new technologies. RT-LAMP tests cdc guidelines for isolating covid patients due rapid antigen tests have been developed and recommended for repeated screening, given that they are less expensive and test results are available faster than PCR tests mins vs. We add the following paragraph to discuss the current use of these tests and their application in the context of isolation strategies Page 9 Line :.
PCR tests provide quantitative viral load estimates, which can be directly compared against the infectiousness threshold. Moreover, as suggested, we have added a more comprehensive review of isolation policies in different countries Page 9 Line :. In most countries, the one-size-fits-all approach is employed; however, the duration is cdc guidelines for isolating covid patients due different among countries. The model we used in the study baseline model is one of the simplest models. As the editors and the reviewers suggested, the model cdc guidelines for isolating covid patients due be extended to incorporate other factors. Following their suggestion, we have added two alternative models, both of which are still universally used for viruses causing acute respiratory infection.
To decrease the number of parameters to be estimated, parametrs f I 0 and k were fixed at 0. In the revised version of the manuscript these two new models are presented alongside the baseline model and compared based on the Akaike information criterion AIC and the Bayesian information criterion BIC. The three models provided very consistent results, which are summarized in Supplementary File 2 and Figure 1.
Overall, all the three models suggest that the personalized approach allows shorted length of unnecessarily isolation and provide quantitatively similar estimates. Together with a new figure Figure cdc guidelines for isolating covid patients duethe following section has been added in the main text Page 8, Line :. We would like to thank once again the editors and reviewers for this comment as we believe that comparing alternative models pagients strengthens our analysis and supports the robustness of our results. We apologize for the lack of sufficient discussion and agree about cdc guidelines for isolating covid patients due relevance of providing the reader with a better context patiente our analysis. We apologize for the lack of discussion about antigen tests. We agree with reviewer about their importance, which we now acknowledge in the revised version of our manuscript Page 9, Line For further details about antigen testing, we refer the reviewer to the response above.
Regarding saliva testing, we have added the following paragraph to acknowledge its relevance and recognize the literature on the topic Page 9, Line :. Indeed, the viral load measured from saliva is comparable to or slightly higher that from nasopharyngeal samples, which guarantees a similar level of sensitivity Tu et al. As suggested, we have now included two alternative models in our analysis. The results of the two additional models are in overall agreement with those obtained with the model presented in the originally submitted manuscript, thus reinforcing our findings. We refer the reviewer to the response above for details. Regarding the estimates of the viral load thresholds required for transmission, we have relied on epidemiological evidence of transmission as derived from contact tracing data.
Nonetheless, we agree with the ppatients that there exists an important body of literature about the connection between SARS-CoV-2 transmission and viral load. We have added the following paragraph to acknowledge the relevance of these studies Page 10, Line :. Specifically, We fully agree with the reviewer that our analysis suffers from the ugidelines mentioned by the reviewer and we apologize for not having stressed them enough in the originally submitted version of the manuscript. We have revised the discussion as follow Page 10, Line :. We apologize for the lack of detail. We here that the test is conducted and the isolation starts immediately after symptom onset.
This has isollating clarified in the Methods Page 13, Line Moreover, we have added the following paragraph in the Discussion to acknowledge the limits of our choice Page 11, Line :. We would like to thank the reviewer for this comment that allowed us to strengthen our analysis. As suggested, we have now considered two additional models taken from the literature. The results obtained with these two additional models are in overall agreement with those obtained in the original analysis, although some quantitative differences do exist, especially in the description of the late phase of the infection.
We echo the reviewer about the fo that guidelines accounting for disease severity may represent a viable option. Unfortunately, as discussed in the originally submitted version of our manuscript and also recognized by the reviewer, the data un availability prevented us to test this hypothesis. We have added the following paragraph to discuss this point, which is still open for future studies Page 10, Line :. Regarding the personalized approach, we assumed that the test is started immediately after symptom onset and we apologize for the omission of this detail.
We have now specified it in the text Page 13, Line We have added the following paragraph to discuss this interesting topic Page 11, Line :. However, starting the tests guidepines early since isolation or symptom onset might be impractical dke it may be determined based on operational and cost constraints. Whether these risks are considered to be acceptable depends on several factors and political choices. Thank you for this comment. As suggested by the reviewer, we have added two alternative models and compared them using both AIC and BIC, finding little difference between them. We apologize for these omissions.
