Coronavirus: How multiple COVID-19 infections can harm your body


With COVID-19 reinfections on the rise, scientists warn that each time you get infected, there is a higher risk of you being vulnerable to troubling health problems in the future. Due to the emergence of the more infectious Omicron variants, people are even reporting their third or fourth infection. Studies have also shown that the Omicron sub-variants such as BA.5 are more capable of evading immunity, compared to the previous variants.

In a new study which has not yet been peer-reviewed, Ziyad Al-Aly, chief of research and development at the Veterans Affairs St. Louis Healthcare System, analysed more than 5.6 million military veterans’ medical records which showed each new COVID infection added to their risk of dying. It also boosted the risks of health problems related to the heart, blood, and brain, as well as diseases such as diabetes, chronic fatigue, and long COVID.
