An illustration has been shared hundreds of times in multiple Facebook and Instagram posts which claim it shows that nasal swab tests for COVID-19 can harm the blood brain-barrier, a semipermeable membrane separating blood from other fluids in the brain. The claim is misleading; experts say COVID-19 swab tests are not placed near the blood-brain barrier and do not pose a risk to human health.
