LENEXA — Tamba Hali fled Liberia when it was in the midst of a bloody civil war. Now that the West African nation is at the center of a very different crisis — an outbreak of Ebola — the Chiefs linebacker is lending his support to a humanitarian relief effort.Hali joined officials from Heart to Heart International, based in suburban Kansas City, to announce Tuesday the construction of a clinic near the capital of Monrovia that will offer 70 beds for patients stricken by the virus.“People are dying,” Hali said, “and they’re dying at a rapid rate.”Liberia has been among the hardest hit nations at the center of the long outbreak, which has killed more than 3,000 people.“The medical system is overwhelmed by the Ebola epidemic, and every doctor and health official said the biggest need is more Ebola treatment units,” said Heart to Heart founder Dr. Gary Morsch. “The world must respond — and urgently — to get control of this outbreak.”As of Friday, there had been 3,834 confirmed Ebola cases and 2,069 deaths in Liberia, according to the World Health Organization.
