New research reveals that COVID-19 attacks the lungs in a far different manner from the flu.
Unlike most respiratory diseases, significant impacts on blood vessels were seen in the lungs of seven COVID-19 patients. The lung tissue of those patients was compared to lung tissue from seven people who died of pneumonia caused by the flu.
There was evidence that COVID-19 attacks the lining of lung blood vessels and COVID-19 patients' lungs had many tiny blood clots and grew new blood vessels in response, according to the study published in the New England Journal of Medicine.
