The World Health Organization (WHO) said on Saturday that it was looking into reports of some COVID-19 patients testing positive again after initially testing negative for the disease while being considered for discharge. According to the WHO’s guidelines on clinical management, a patient can be discharged from hospital after two consecutive negative results in a clinically recovered patient at least 24 hours apart. Based on current studies, there is a period of about two weeks between the onset of symptoms and clinical recovery of patients with mild COVID-19 disease. “As COVID-19 is a new disease, we need more epidemiological data to draw any conclusions of virus shedding profile,” the WHO said. The number of deaths linked to the novel coronavirus reached 100,000 on Friday, as reported cases passed 1.6 million, according to a Reuters tally.
