The same derisive chants greeted the Leone Stars as they took the field Saturday in a 0-0 tie against Cameroon, then subsided until late in the game, another “home” match for the team, played more than 1,500 miles from their West African nation.

While facing Cameroon twice in five days, the Stars must submit at breakfast and dinner to temperature screenings for Ebola, even though none play professionally in Sierra Leone or have even traveled to the country since July. After last month’s match in Congo, some players were screened four times in a single day as they attempted to return to their club teams in Europe and the United States.

Trye said he was detained Wednesday night for three hours by immigration authorities after flying into Douala, Cameroon. But rather than submit to yet another Ebola screening, he took a four-hour bus ride instead of a 30-minute connecting flight to reach Yaoundé, the capital.

Players understand that countries must guard against the spread of the virus, said Kei Kamara, a Sierra Leone forward who remained with his club team, the Columbus Crew of Major League Soccer, rather than travel to Cameroon. What is disheartening, Kamara said in a telephone interview, is that “we’re treated like we’re walking around with the disease.”

The chaos related to Ebola worsened last week, with infighting between Sierra Leone’s soccer federation and its sports ministry; the two have long jousted for control of the national team. The factions appointed separate replacements for the previous coach, who was fired last month.

FIFA, soccer’s world governing body, threatened to bar Sierra Leone from future competitions unless the sports ministry quit interfering. The players were caught in the middle, and threatened by the ministry Saturday with nonpayment. The issue was not resolved until 15 minutes before kickoff.
