Patients who had severe COVID-19 may be twice at risk of dying over the following year, compared to patients who had a mild or moderate case, or individuals not infected by novel coronavirus, according to a new study.
The study also found that common complications due to COVID including respiratory failure and clotting disorders were responsible in only 20 percent of the severe Covid-19 patients’ deaths. These findings suggest that the patients who survived severe cases of COVID-19 were left vulnerable to other illnesses due to an overall deterioration in their health, according to the authors of study. The researchers defined a severe COVID-19 case as a patient who needed to be hospitalized within the first 30 days of testing positive for the infection.
"Since we now know that there is a substantial risk of dying from what would likely be considered to be an unrecognized complication of Covid-19, we need to be even more vigilant in decreasing severe episodes of COVID-19," Professor Arch Mainous of the University of Florida who is the lead author of the study said in a news release.
