6. Lassa fever also causes a marked suppression of the immune system, an aspect of the disease that the researchers are tracking with the current marmoset vaccine study.

7. Lassa fever is known to be endemic in Guinea (Conakry), Liberia, Sierra Leone and parts of Nigeria, but probably exists in other West African countries as well.

14. On rare occasions, travellers from areas where Lassa fever is endemic export the disease to other countries.

15. Because the symptoms of Lassa fever are so varied and non-specific, clinical diagnosis is often difficult, especially early in the course of the disease.
