Hosts of CWD include "Coffea arabica" (Arabica coffee), "Coffea canephora" (Robusta coffee), "Coffea liberica" (Liberian coffee), and "Coffea excelsa" (Excelsa coffee) Currently, the disease is limited to Eastern and Central Africa, however, studies have shown that most "Coffea" species are likely susceptible to the disease, which can potentially lead to more worldwide problems in the coffee industry.
