Most people who die from COVID experience lung complications such as inflammation with ARDS and/or blood clots.
COVID can affect organs beyond the lungs, but patients primarily die as a result of lung complications.
Blood clots play a significant role in severe COVID disease, contributing to inflammation and cytokine storm.
Pre-existing medical conditions, obesity, and heart disease increase the risk of severe COVID and complications.
Further research is needed to determine who should receive blood thinners and other preventive treatments.
