An elderly French man who caught the Zika virus while on vacation developed a brain infection that put him in a temporary coma, according to a new report of the case.
The 81-year-old man had been healthy before he went on a cruise to the South Pacific — one of the regions where the Zika virus is spreading.
Ten days after he returned home, he was admitted to the intensive care unit in a coma. The man had a fever, and later developed a rash — both symptoms of Zika virus infection.

Brains scans showed that the man had a condition called meningoencephalitis, which is inflammation in the brain and the meninges, or the membranes surrounding the brain. A test of the man's cerebrospinal fluid was positive for Zika virus.
Zika virus has garnered international concern because of the strong link between infection with the virus in pregnancy and microcephaly, a birth defect in which a child's head is abnormally small.
But doctors should also "be aware that ZIKV may [be] associated with meningoencephalitis," the researchers said, referring to Zika virus. [5 Things to Know About Zika Virus]
The man spontaneously awoke from his coma after one day in the hospital, but he had hallucinations and weakness in his left arm. However, his condition improved without a specific treatment, and he was released from the hospital after 17 days and fully recovered after 38 days, the researchers said.
Zika virus has also been linked to Guillain-Barré syndrome, a condition of the nervous system that can cause paralysis.
The study is published today (March 9) in the New England Journal of Medicine. It was conducted by researchers at the Paris hospital system Assistance Publique – Hôpitaux de Paris.
