A 31-year-old male asked:

If a covid test was done incorrectly towards the brain instead of the nasopharynx could it cause cerebrospinal leak?

Confusing post: The nasopharynx is the structure where most covid test s are sampled. The structures extend the length of the nasal airway to the back of the throat down to the voice box. The brain is behind & above nasopharyngeal tissue & a bony plate. While sampling can be uncomfortable, it is not a brain sample.

Very very rare: Among the multi-million tests done, there has been one reported incident of CSF leak. You are more likely to experience a lightning strike or a snake bite than CSF leak from nasopharyngeal swab. Get HPV and Covid vaccines. Wish you good health!

Would be very rare: Almost impossible for a COVID-19 test to puncture the base of brain and cause a spinal fluid leak. And the anatomy of the nasopharynx actually points away from the base of brain.
