As the COVID-19 virus continues to evolve, a new study says getting the virus two or more times could raise the risk of new serious health problems and even death.

The study looked at the records of more than 5 million patients in the Veterans Affairs health system.

The study found that people with two or more reported infections had more than twice the risk of dying compared to those with just one COVID-19 reinfection.

Researchers say reinfection also increased the likelihood of getting lung and heart problems, diabetes, digestive and kidney disorders as well as neurological problems.
