Spinal Taps and the Poliovirus

Question: How much of the poliovirus can they remove when doing a spinal tap?

Dr. Bruno’s Response:  Between 5 to 20 milliliters (ml), or about 2 to 8 oz, of cerebrospinal fluid (CSF) is collected in a spinal tap. In patients with a diagnosed meningitis caused by common enteroviruses (viruses that live in your gut, like poliovirus) an average viral load would be 500,000 copies of the virus in each ml of CSF.

So, in 5 ml, about 2,500,000 poliovirus particles could be found. In 20 ml there could be 10,000,000 poliovirus particles.   Source Article 

Something of interest:  About 17,000 poliovirus particles would cover the period at the end of this sentence.
