Wednesday, October 16, 2002Biopsies of Lewis' patients suggest that the virus had attacked the grey matter in the spinal cord, which contains nerve fibres running to and from the muscles. Why this sometimes affects only one side of the body is unknown. This is new, and some speculate that it might be caused by a mutation in the virus, but the virus is also new to us, so it could just represent another piece of understanding of its natural history. Although the West Nile virus has been present in the Third World for a long time, it’s never been subject to as much scrutiny and testing as it has since it gained our shores. ADDENDUM: The case reports from The New England Journal of Medicine documenting this, can be found here.
