Right if you read the article he was the only one that both left the ship and was later confirmed as infected. There was another Dutch couple that left while sick and quickly were hospitalized. My concern is he was able to move around freely all while he was unknowingly infected. He seems to be the one that had the most opportunity to spread the infection.

Others also left early and have been quarantined. They have not shown symptoms so I didn't bring them up when discussing spread. One infected couple left early as well, but they were already sick and didn't leave South Africa. Although they may have infected a flight attendant, still waiting on tests.

Of course the virus can have a long incubation period. So these individuals may be more relevant to discussion later. There are those that were evacuated to recieve medical treatment elsewhere, but it's not like they are walking around their respective countries.
