No one had warned Joosten and Taal about the potential hazards of an African bat cave. They knew nothing of Marburg virus (though they had heard of Ebola). They only stayed in the cave about ten minutes. They saw a python, large and torpid. Then they left, continued their Uganda vacation, visited the mountain gorillas, did a boat trip, and flew back to Amsterdam. Thirteen days after the cave visit, home in Noord-Brabant, Astrid Joosten fell sick.
