A link to this thread has been posted on the Ebola Surveillance Thread
(Marburg is one of the other two filovirus families and has similar effects to Ebola).
“Family” should read genera. Technically in the system of binomial nomenclature, the Marburg virus is a different Genus than Ebola, but they are in the same Family (Kingdom, Phylum, Class, Order, Family, Genus, Species are the technical names for the branches of the identifying tree of taxonomy).
Thanks for the ping!
