Zika ‘link’ to paralyzing myelitis found
The Zika virus, suspected of causing brain damage in babies and a neurological ailment in adults, has now also been linked to the paralyzing disorder myelitis, French researchers say.
A 15-year-old girl diagnosed with acute myelitis in January had high levels of Zika in her cerebrospinal fluid, blood and urine, says Annie Lannuzel of the University Hospital Center Pointe-a-Pitre in Guadeloupe.
“This is the first published case to offer proof of a link” between myelitis and the virus sweeping Latin America and the Caribbean, she tells AFP.
The case had been described in a report published in The Lancet medical journal.
“The presence of Zika virus in the cerebrospinal fluid of our patient with acute myelitis suggests that this virus might be neurotropic” — something that attacks the nervous system, Lannuzel and a team write in the case report.
Zika usually causes mild symptoms in adults, with a low fever, headaches and joint pain, but the virus’ quick spread has raised alarm due to an observed association with more serious health conditions.

Myelitis is an inflammation of the spinal cord which can affect limb movement and cause paralysis.
In the reported case, a teenaged girl was admitted to the Pointe-a-Pitre hospital with partial paralysis, limb weakness, and intense pain.
Nine days after the symptoms began, doctors found high levels of Zika virus in her blood, spinal fluid and urine, said a statement from France’s Inserm medical research institute.
Other potential causes of myelitis were ruled out, including shingles, chicken pox and herpes virus.
The girl’s condition has since improved and she is now out of danger, says the statement.
“My message is that Zika does not only affect pregnant women, and is not necessarily benign,” says Lannuzel.
