SINGAPORE—According to a new study released on May 23, which was conducted by experts in Singapore who monitor situations pertaining to infectious disease, patients who have contracted COVID-19 may not be infectious after 11 days.
Based on the epidemiologic and microbiologic data compiled they analyzed a period of infectivity, where the study discovered that this specific period usually starts two days before the symptoms begin, and continues for 7 to 10 days. Whatever active viral infection exists in the body starts to wane away, and once the second week arrives any inkling of the coronavirus in the system no longer exists.
The study was able to determine that patients are no longer infectious after 11 days by testing various numbers of what’s referred to as infectors-infectees from multiple countries including China, North and South Korea, Singapore and Germany, and analyzing the cycle threshold value (Ct) by culturing specimens from the throat and lungs. When they compiled all the test results, the coronavirus was not isolated or cultured after 11 days of existing in the human body.
The results of this study were revealed after the National Centre Infectious Diseases and the Academy of Medicine, both based in Singapore, who joined together to author a research paper to address the pandemic, which has infected more than 5 million people worldwide, and lead to, at least, 345,000 total deaths.
Due to that low figure, the Singaporean government has decided that it will be reopening its pre-schools on Tuesday, June 2.
