A hand can be seen holding a thermometer at The Ivy Apartments where a man diagnosed with the Ebola virus was staying in Dallas, Texas October 2, 2014. Up to 100 people may have had direct or indirect contact with the first person to be diagnosed with the Ebola virus in the United States, and four of his relatives have been quarantined in an apartment in Dallas, health officials said on Thursday.
