So far, there hasn't been enough research to conclude why symptoms seem to re-emerge in some people, and whether they experience reinfection or if the virus persists for weeks. One possibility is that Covid-19 causes blood clots that may cause potentially dangerous complications unless treated with anticoagulant medications, said Edwin J.R. van Beek, chair of clinical radiology at the University of Edinburgh's Queens Medical Research Institute.
South Korean researchers also offered some clues this week when they reported that so-called nucleic acid tests might be positive based on the detection of dead viral particles that could give the false impression that a patient is still infectious when they're not. "Everyone's trying to figure this out," said Yvonne Maldonado, an infectious diseases professor at Stanford Medical School. "What happens when people have been sick and infected - are we going to consider them immune and, therefore, not susceptible at all? Or are they immune and serve as potential points of infection for other people?"
Officials in countries that managed to suppress an initial wave of the pandemic are dreading the possibility that the virus may have a seasonal pattern and could return in the fall and repeat the nightmare scenario.
