Patients hospitalised with COVID-19 remain at a higher risk of death three years after infection.
Research has revealed that those who were admitted to hospital within the first 30 days of contracting the virus had a 29 per cent increased chance of passing away in the third year after the infection compared to those who have not had the disease.
Expert Dr. Ziyad Al-Aly, of Washington University, said: "We tend to think of infections as mostly short-term illnesses with health effects that manifest around the time of infection. Our data challenges this notion.
"Even three years out, you might have forgotten about Covid, but Covid hasn't forgotten about you.
"People might think they're out of the woods, because they had the virus and did not experience health problems. But three years after infection, the virus could still be wreaking havoc and causing disease or illness in the gut, lungs or brain."
