In this July 2012 photo provided by Ryan Boyko, Boyko is shown working in a lab in the Democratic Republic of Congo. Boyko, a Yale doctoral student, said Tuesday Oct. 28, 2014, that the Connecticut order to quarantine him at home following his return from Liberia earlier in the month was based on politics, not science. Boyko, 30, has been confined to his apartment in New Haven out of concern that he was exposed to Ebola while helping Liberia's government develop a computer system to track the virus.
