The doctor who treated him became ill on 11 August. He continued treating patients at his private clinic for 2 days, operating on at least two of them. Between 13 and 16 August, he was ill enough that he stayed home, but, according to the WHO report, he received multiple visitors who came to celebrate the birth of a baby. On 16 August, he was hospitalized. He did not tell doctors there that he had been exposed to Ebola.
What an asshole!
Apparently, even a venerable website such as Science isn't immune to trolls posting racist comments.
