United flies Lagos-Houston.
It doesn't mean that he wasn't contagious. Scientists are not entirely sure about all the ways Ebola can be communicated. Deaths of many doctors in Africa are a clear proof of that - they were not protecting themselves enough. In the USA Ebola is studied in biosafety level 4 labs (the highest.)
United flies Lagos-Houston.
Lagos is in Nigeria, not in Liberia. 972.46 miles as crow flies. He had to take a regional jet for that hop.
