There was panic and alarm when Ebola virus first emerged as a fatal bleeding disease in Congo (Zaire) in 1978. Similar outbreaks in neighboring countries in Africa occured. Transmitted mainly by body fluids, the acute infection (aka Ebola hemorrhagic fever, EHF) of the Filoviridae family of RNA viruses presented like a typical viral infection--- fever, headache, joint and muscle pain, sore throat, and weakness after an incubation of 2 to 21 days. Some manifested with a skin rash, conjunctival injection, diarrhea, vomiting, stomach pain, internal and external bleeding.

The Ebola-Reston (ERV,) the fifth subtype of the virus was first found in Philippine monkeys. It has caused disease in
primates, but not in humans. Mainly because this that local health authorities seem to be “in control” over the simmering Ebola outbreak that has infected pigs in Pandi, Bulacan.
