In this Feb. 11, 2016 photo, a child cries as he held by his mother who waits in line to sign in to see a doctor at a medical center near Petare neighborhood in Caracas, Venezuela. Preventing the Zika virus&#039; spread in the absence of a public campaign in a Venezuela where the health care system is near collapse means the people most at risk, the poor, don&#039;t even know about the epidemic. Chronic shortages have left the country without insect repellent or contraceptives, leaving women unable to guard against pregnancy, not to mention sexual transmission of the virus.
