Studies Find Lasting COVID Risks: Brain Changes in Infants, Stroke Risk in Adults
Nonhospitalized COVID-19 patients had a 73% higher risk of stroke up to one year post-infection compared with other acute respiratory infections, study finds.
- Using PCORnet data from April 1, 2022–April 30, 2023, a study in CDC's Emerging Infectious Diseases found even mild COVID-19 raises stroke and thrombotic risk up to one year after illness.
- Earlier studies focused on the first 30 days after infection, leaving longer-term thrombotic risk unclear and many prior analyses centered on pre-Delta and Delta variant study periods.
- Measured data show an overall incidence ratio of 1.63, with nonhospitalized patients with COVID-19 facing a 73% increased risk for thrombotic events in days 31–365, risk ratios 1.73 versus 1.14 in hospitalized patients.
- Clinicians and public-health officials should increase stroke awareness and monitoring, as authors say data support prevention, chronic-disease management, and COVID-19 vaccination to reduce severe illness and thrombotic risks.
- Investigators say mechanisms remain uncertain, including endothelial cell damage, viral-triggered exaggerated immune response, and persistent microthrombi; longitudinal follow-up and future studies should clarify long-term cardiovascular consequences.

Covid-19 and cardiovascular disease in a total population-study of long-term effects, social factors and Covid-19-vaccination - Nature Communications
Understanding more about the risk of cardiovascular disease in the large population-group with mild Covid-19 is essential since the preventive need might be extensive. This study examined the risk of cardiovascular disease following Covid-19, considering risk periods and prognostic factors i.e., social factors, Covid-19-vaccination and comorbidities. The study cohort included the Swedish population aged 40-75 years (n = 4,095,414). Covid-19 was …
