In Brazil, response workers who are helping to battle the Zika virus have threatened to go on strike. These workers are demanding sunscreen, uniforms and bug repellent, as well as improved working conditions. If these demands are not met by Thursday, it is expected that as many as 7,000 people will go on strike. In addition to this, as many as 220,000 additional workers could join the strike if conditions do not improve in the long-run.
