Ebola hemorrhagic fever, made famous by Richard Preston's "The Hot Zone," is an extremely terrifying disease with a 50-90% mortality rate that has caused several outbreaks in Africa's Congo and Zaire. The Aum Shinrikyo cult infiltrated Zaire in an attempt to obtain the Ebola virus.
The Soviet Union also developed biological weapons using the smallpox virus (declared eradicated by the WHO in 1979). Smallpox is an extremely dangerous virus with a 30% mortality rate, and unlike chemical weapons, it is invisible and spreads from person to person. Furthermore, Dr. Alibekov has suggested that the Soviet Union may have developed a chimera of the Venezuelan encephalitis virus and the smallpox virus, and possibly even a chimera with the Ebola virus. While the facts are unknown, it is entirely possible with modern molecular biology technology. It would also be possible to develop vaccine-ineffective strains. Currently, the smallpox vaccine becomes ineffective after 10 years, so no one in Japan has immunity to smallpox. If one case of smallpox were to occur in Japan today, it would mean 20 more cases in two weeks, 400 in four weeks, 16,000 in six weeks, and the entire Japanese population in eight weeks. Therefore, if we fail to detect and isolate smallpox in its early stages, it will engulf not only medical institutions but everything. The United States has been mass-producing smallpox vaccines for the past five years.
