Zika Virus' Link To Microcephaly: WHO Says It Could Be Proven Within Weeks

Zika virus is known to cause fever, headache, muscle pain, joint pain, rashes, and red eyes. According to the World Health Organization (WHO), Zika virus' link to microcephaly could be confirmed within weeks.

The virus has been linked to the rise of cases of the birth defect microcephaly, but it has not been scientifically proven, Reuters reported. This could all change in a matter of weeks.

"It seems indeed that the link with Zika (and microcephaly) is becoming more and more probable, so I think that we need a few more weeks and a few more studies to have this straight," WHO assistant director-general for health systems and innovation Marie-Paule Kieny told the media.

The Zika virus outbreak has spread to more than 30 countries, with Brazil taking the biggest hit. The total cases of microcephaly in Brazil have been updated on Friday, bringing the number up to 4,314 cases. Microcephaly is a birth defect that results into an infant's head that is smaller than usual caused by brain abnormalities, according to Mayo Clinic.

Because of Zika virus' link to these birth defects, some health experts from countries like El Salvador have advised women not to get pregnant for a couple of years. U.N health experts have also advised pregnant women to avoid travelling to countries with Zika virus cases.

Scientists from the U.S. and India are currently leading the way in creating an effective vaccine for the Zika virus. However, it would take at least 18 months before large-scale clinical trials are realized.

The Centers for Disease Control and Prevention (CDC) shared a few tips to prevent Zika virus infection from mosquito bites. Wearing long sleeve shirts and pants as much as possible; always keeping the windows and doors closed; applying insect repellants; and treating clothes with permethrin are some of the most effective ways to avoid getting the virus.
