A new study that scientists have discovered that the coronavirus can stay in one’s system for over 37 days.
This means it is possible to transmit the infection even after the symptoms subside.
This duration is called Viral Shedding which means the length of time where the virus can be spread from someone infected. In the case of Covid-19, the Viral Shedding period was found out to be 37 days with 20 days as a median period. This means we need to extend our isolation period of 2 weeks currently to more days.
The Chinese researchers who have collected Lab records and medical data to track Covid-19 presence in over 190 patients treated at Jinyintan Hospital and Wuhan Pulmonary Hospital say that over 54 patients have died from the infection and the virus remained in the system until death.
The results from the study said “important implications for both patient-isolation decision-making and guidance around the length of antiviral treatment,” Dr. Fei Zhou, of the Peking Union Medical College, writes in the report. The study also notes that 48% of patients had various other ailments such as hypertension, diabetes and heart disease which decreased their chances of survival.
This is different from the SARS outbreak in 2003, where the only 1/3rd of the patients had carried the virus after death even after 4 weeks of passing away, the study notes.
According to WHO, for influenza patients, viral shedding typically persists 5 to 10 days, beginning within 24 hours before or after the onset of symptoms. Children and immunocompromised individuals, however, may shed longer, for weeks or months.
