Three people in Colombia have died after contracting the Zika virus and developing a rare nerve disorder called Guillain-Barre, the first time health officials have directly blamed the mosquito-borne disease for causing deaths.
"We have confirmed and attributed three deaths to Zika," said Martha Lucia Ospina, head of the National Health Institute. "In this case, the three deaths were preceded by Guillain-Barre syndrome." Guillain-Barre is a rare disorder in which the immune system attacks the nervous system.
Cases of the syndrome, which causes weakness and sometimes paralysis, have increased in tandem with the outbreak of the Zika virus currently sweeping Latin America. The timing has raised health officials' suspicions that the neurological condition is a complication of the mosquito-borne virus.
Ospina, an epidemiologist, said another six deaths were under investigation for a possible link to Zika. "Other cases (of deaths linked to Zika) are going to emerge," she said. "The world is realizing that Zika can be deadly. The mortality rate is not very high, but it can be deadly."
Colombia has been hit hardest by the Zika outbreak of any country except Brazil, with more than 20,000 cases, including more than 2,000 pregnant women. Zika normally causes mild flu-like symptoms and a rash, or goes unnoticed altogether. But Colombian Health Minister Alejandro Gaviria said the apparent risk of deadly complications was "worrying."
