Patients who survived severe COVID-19 were found to experience twice the risk of dying over the next 12 months, compared with patients who experienced mild or moderate disease or remain uninfected. The findings of the study are published in Frontiers in Medicine . Unusually, the increased risk of dying was greater for patients who are under 65, and only 20% of the severe Covid-19 patients who died did so because of typical Covid complications, such as clotting disorders or respiratory failure. The study suggests that severe Covid-19 may significantly damage long-term health and highlights the importance of preventing severe disease through vaccination.
‘Severe COVID-19 is associated with a higher risk of dying over the next 12 months, with patients under 65 showing the most risk.’
Reality of long Covid Covid-19 can cause severe symptoms and death for vulnerable people, particularly older patients and those with certain underlying conditions. You have likely also heard of long Covid, where symptoms such as fatigue and shortness of breath can linger for months after the infection has passed.
But how do Covid-19 patients fare in the long-term? Researchers have been tracking patients to understand the long-term impacts of the disease. “We conducted a previous study that showed that patients with severe Covid-19 who recovered were at significantly greater risk of being hospitalized in the subsequent six months,” explained Prof Arch Mainous of the University of Florida, lead author on the study. “This new study extended that to investigate mortality risk over the next 12 months.”
The researchers tracked electronic health records of 13,638 patients who underwent a PCR test for Covid-19 within the University of Florida health system, with 178 patients experiencing severe Covid-19, 246 mild or moderate Covid-19 and the rest testing negative. All patients included in the study recovered from the disease, and the researchers tracked their outcomes over the next 12 months.

The study found that patients who had recovered from severe Covid-19 had a significantly greater chance of dying over the next year, compared with the uninfected and mild or moderate Covid-19 patients. Some surprising trends emerged from the data, with severe Covid-19 patients aged under 65 demonstrating a 233% increased chance of dying, compared with the uninfected. This was larger than the increased chance of dying experienced by severe Covid-19 patients aged over 65, compared with the uninfected. As these deaths frequently occurred long after the initial infection had passed, they may never have been linked to Covid-19 by the patients’ families or doctors.

“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,” said Mainous. “Taking your chances and hoping for successful treatment in the hospital doesn’t convey the full picture of the impact of Covid-19. Our recommendation at this point is to use preventive measures, such as vaccination, to prevent severe episodes of Covid-19.”
