How long do COVID-19 patients continue to shed the virus?
The duration of viral shedding varies significantly and may depend on severity. Among 137 survivors of COVID-19, viral shedding based on testing of oropharyngeal samples ranged from 8-37 days, with a median of 20 days.
Can patients who have recovered from COVID-19 continue to have detectable SARS-CoV-2 RNA in upper respiratory specimens?
• Patients who have recovered from COVID-19 can continue to have detectable SARS-CoV-2 RNA in upper respiratory specimens for up to 3 months after illness onset in concentrations considerably lower than during illness; however, replication-competent virus has not been reliably recovered and infectiousness is unlikely.
Is it possible to have lingering symptoms of COVID-19?
“Some symptoms of COVID-19 linger longer than others,” says Dr. Septimus. “In particular, fatigue and loss of taste and smell can persist beyond the period of contagion.”While uncomfortable and/or inconvenient, Dr. Septimus adds that these lingering symptoms aren’t too worrisome for most people.
What are some of the persistent symptoms of COVID-19?
The most common persistent symptoms reported in the follow-up survey were fatigue and loss of taste or smell, both of which were reported among 24 patients (13.6%). Other symptoms included brain fog (2.3%).
How long can you spread COVID-19 after testing positive?
People with COVID-19 can spread the virus to other people for 10 days after they develop symptoms, or 10 days from the date of their positive test if they do not have symptoms. The person with COVID-19 and all members of the household should wear a well-fitted mask and consistently, inside the home.
Should the person who has clinically recovered from COVID-19 continue to wear a cloth face covering in public?
Yes. It is recommended that all persons, with a few exceptions, wear cloth face coverings in public.
Can you still have detectable SARS-CoV-2 RNA after recovering from COVID-19?
Some people who have recovered may have 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.
Are recovered persons with persistent positive test of COVID-19 infectious to others?
See full answerPersons who have tested persistently or recurrently positive for SARS-CoV-2 RNA have, in some cases, had their signs and symptoms of COVID-19 improve. When viral isolation in tissue culture has been attempted in such persons in South Korea and the United States, live virus has not been isolated. There is no evidence to date that clinically recovered persons with persistent or recurrent detection of viral RNA have transmitted SARS-CoV-2 to others.Despite these observations, it’s not possible to conclude that all persons with persistent or recurrent detection of SARS-CoV-2 RNA are no longer infectious. There is no firm evidence that the antibodies that develop in response to SARS-CoV-2 infection are protective. If these antibodies are protective, it’s not known what antibody levels are needed to protect against reinfection.
What are some symptoms of COVID-19 long haulers?
Those individuals are often referred to as “COVID long-haulers” and have a condition called COVID-19 syndrome or “long COVID.” For COVID long-haulers, persistent symptoms often include brain fog, fatigue, headaches, dizziness and shortness of breath, among others.
How long after being tested positive for COVID-19 can you can resume being around others, if you have no symptoms?
If you continue to have no symptoms, you can be with others after 10 days have passed since you had a positive viral test for COVID-19.
What is the prognosis of viral shedding in nasopharyngeal secretions post covid-19?
We found evidence of persistent viral shedding in nasopharyngeal secretions more than 2 weeks after resolution of symptoms from confirmed COVID-19 infection. Persistent shedding was more common in older participants, and viral load was higher among older positive participants.
What is the duration of SARS-Cov-2 viral shedding?
Through such PCR tests, viral shedding of SARS-CoV-2 has been found to have a median duration of 12 to 20 days, with a persistence that can reach up to 63 days after initial symptom onset.
What does the solid line mean in infectious virus shedding?
Solid line, shedding of infectious virus; dashed line, virus not readily demonstrable; +, disease episode. Latent infection is characterized by the lack of demonstrable infectious virus between episodes of recurrent disease.
Does the sampling location affect the duration of viral shedding?
In addition to symptom severity being a predictive factor of viral shedding duration, the sampling location also appears to determine when peak viral loads occur.
