Zika, a New Threat. What Is It (in Spanish with English subtitles)
Excerpt from Zika virus spreads across Americas as concerns mount over birth defects. (2015). BMJ, 315, h6983.
Zika’s rapid geographic spread would be causing less concern to public health authorities were it not for worrying evidence that the disease is less benign than initially thought. Hundreds of cases of Guillain-Barré syndrome have sprung up in the wake of Zika infection, but it is an explosion of microcephaly among infants born to infected women that has caused Brazil to declare Zika a “public health emergency of national importance.”
Basic info on Zika
According to PAHO, “Zika fever is a mosquito-borne viral disease caused by Zika virus (ZIKV), consisting of mild fever, rash (mostly maculo-papular), headaches…and non-purulent conjunctivitis, occurring about three to twelve days after the mosquito vector bite. One out of four people may develop symptoms, but in those who are affected the disease is usually mild with symptoms that can last between two and seven days. Its clinical manifestation is often similar to dengue, also a mosquito-borne illness.”
There is currently no vaccine or specific treatment for Zika virus infection. Therefore, treatment for everyone, including pregnant women, is directed at alleviating symptoms.
Factsheet from the World Health Organization (WHO)
How does Zika virus affect pregnant women and fetuses?
Fetuses exposed in utero to the Zika virus are at risk for microcephaly, a condition where a baby’s head is much smaller than expected. Babies with microcephaly can suffer from various problems, such as developmental delay, intellectual disability, hearing loss, and vision problems.
