The Ugandan Ministry of Health is reporting today that a 30-year-old male health care worker died of Marburg hemorrhagic fever on September 30. Marburg is one of the five members of the family of filoviruses, to which Ebola belongs. Like Ebola, a person infected with Marburg will experience a sudden onset of fever. The most common additional signs are headache, joint and muscle pains, vomiting blood, and bleeding through body openings. The disease has a two to 21-day incubation period and, like Ebola, has no cure other than supportive treatment. Tekmira Pharmaceuticals of Burnaby, British Columbia, has a lipid nanoparticle, RNA interfering drug that also protects non-human primates from Marburg infection. This work, done with Thomas Geisbert at the University of Texas Medical Branch at Galveston, appeared in Science Translational Medicine in August. There, the drug is called NP-718m-LNP, but Tekmira’s website currently calls it TKM-Marburg.
