Apparently this virus is transmitted by mosquitoes. It is causing thousands of babies to be born microcephalic. Women in the areas where this is happening are being told to avoid pregnancy for two years in the hope that a vaccine may be developed during that time. It sounds horrendous and completely unforeseen. It must have huge implications for any woman of child bearing age who lives there but also for any female who is travelling there. Does anyone know why this has suddenly started to cause these birth defects in such huge numbers? Apparently more than 4,000 babies with microcephaly have been born in Brazil since October.
