Description
Reza Sadeghi and two co-authors studied COVID-19 deaths in an Iranian hospital system in a 2026 paper. It was well known that older patients and those with other illnesses died more often. What had not been checked is whether that extra risk plays out the same way in each age group.
The study covered 10,496 patients with confirmed infection in the city of Sirjan. About one in five had at least one other illness, most often high blood pressure or diabetes. Just over four percent of all patients died, and nearly half of those who died had another illness. Having any other illness more than tripled the odds of death overall. Splitting the data into three age bands let the team show how the burden shifts with age. The results can help hospitals triage the patients most at risk.
