Addressing the reported appearance of Nile-virus-carrying mosquitoes in Athens, Papachristou wrote: "With so many Africans in Greece, the West Nile mosquitoes will be getting home food!!!" The following week, on August 3, German Olympic officials said that rower Nadja Drygalla had left the Olympics after a broadcaster reported that her boyfriend is a supporter of an extreme right-wing party in Germany. Drygalla, a member of the women's eight crew, left the Olympic village to avoid any "burden for the Olympic team," said Michael Vesper, general director of the national Olympic association. According to Yahoo Sports, Drygalla's boyfriend was reportedly "a leader of the Rostock National Socialists, a group German intelligence describes as neo-Nazi and racist."
