From the day of contact with the infected person or family members, they should be isolated for 14 days. Fitzgerald pointed out that a negative test is not a free pass to pass the quarantine, because it may test positive after a few days, because the virus may take several days to manifest.
Fitzgerald said: “People who are thought to be positively exposed want to be tested so that they can continue to go out, but a negative test does not mean you can continue (leave home)…” “People who are exposed want to return to work. But there is actually no way to isolate (isolate).”
Infected persons should be quarantined on the day of the onset of symptoms or the test result is positive, and quarantine for 10 days from that day.
Fitzgerald pointed out that “infected people spend less time in quarantine than in contact, but not necessarily the time spent in quarantine, but contrary to intuition”, but CDC data shows “ People with mild to moderate COVID-19 are still infectious no more than 10 days after the onset of symptoms.”
However, patients with severe to severe viral infections can remain infected for up to 20 days after the onset of symptoms. Therefore, whether to continue isolation after 10 days depends on whether the patient has no fever for at least 24 hours and does not have a fever to reduce medication. All other symptoms are absent.
Fitzgerald added that those who test positive but are asymptomatic are not immune from isolation. He said: “People who test positive for PCR but asymptomatic find it hard to believe that they have the virus.” However, PCR testing is rarely inaccurate.
