Having spent 18 years in the NBA and standing at 7 feet, 2 inches, former basketball star Dikembe Mutombo is highly recognizable. Now Mutombo has teamed up with the US Centers for Disease Control and Prevention to help spread communication about Ebola with the people of the Democratic Republic of Congo. "I care deeply about our country, and I need your help to stop the Ebola outbreak in the north part of the country," Mutombo, who is Congolese, said in a public service announcement. More than 6 of every 10 of our brothers and sisters sick with Ebola have died, including many of our children. Mutombo, an eight-time All-Star and four-time NBA defensive player of the year, played for six teams in his NBA career, retiring in 2009.
