Media reported that because the new crown virus is so new that the guidelines of national and international health organizations will be adjusted every other week, if not every day. Although the U.S. Centers for Disease Control and Prevention (CDC) is currently under the control of the Trump administration, the organization continues to adjust information about the virus, and the latest update is particularly important. On Friday, the agency made a major change to guidelines for home-based rehabilitation of patients with new crown pneumonia.
Previously, the CDC recommended that patients with symptoms of new coronary pneumonia should be quarantined at home for at least 10 days after developing symptoms, and then stop isolation at least 72 hours after the last sign of fever — and without using any defever medications. As of July 17, the center said that after 10 days of quarantine, it was unlikely to infect others if there was no fever for 24 hours.
“After symptoms, the concentration of SARS-CoV-2 RNA detected in the upper respiratory tract sample decreased,” the CDC said in a new document explaining its guidelines. “
“After symptoms, the likelihood of restoring a virus that has the ability to replicate decreases. For patients with mild to moderate new coronary pneumonia, the replicable virus does not recover after 10 days of symptoms. Some patients with severe neo-coronary pneumonia have recovered from the replicable virus within 10 to 20 days of the onset of symptoms, which in some cases is compounded by immunocompromised dysfunction. However, it is estimated that 88% and 95% of the specimens in this range of patients no longer produce replication-active viruses 10 and 15 days after symptoms. “
In addition, the document states that a review is not recommended for patients who have recovered and who no longer develop symptoms.
The second change is more semantic, but it is just as important. The guidelines for patients with isolation of new coronary pneumonia previously noted that one of the criteria for ending isolation is “improvement of respiratory symptoms,” but as the list of symptoms has expanded dramatically, the CDC has updated its page to call it “symptom improvement.” It is reported that a long list of symptoms of new coronary pneumonia seems to be increasing every week, and now includes fatigue, loss of taste and sense of smell, nausea, vomiting, diarrhea and other non-respiratory complications.
