Microscope image of a microclot found in the blood of a person with Long COVID (enlarged 63 times). The green areas show an abnormal, sticky protein network, while the red and blue areas come from immune cellular material that has become trapped inside the microclot. Together, they form dense clumps that may block tiny blood vessels and reduce oxygen flow, a process thought to play a role in the ongoing symptoms seen in Long COVID.
