SARS-CoV-2, the virus that causes COVID-19 , may preferentially use a "back door" into cells to infect the brain.

The finding could partly explain why many people have neurological symptoms such as fatigue, dizziness, brain fog.

Researchers found mutations in the virus's spike protein, which it uses to enter human cells by binding to a molecule called ACE2 .
