Safety concerns at a prominent military germ lab have led the government to shut down research involving dangerous microbes like the Ebola virus.
In the statement, the C.D.C. cited “national security reasons” as the rationale for not releasing information about its decision.

The institute is a biodefense center that studies germs and toxins that could be used to threaten the military or public health, and also investigates disease outbreaks. It carries out research projects for government agencies, universities and drug companies, which pay for the work. It has about 900 employees.

The suspended research involves certain toxins, along with germs called select agents, which the government has determined have “the potential to pose a severe threat to public, animal or plant health or to animal or plant products.” There are 67 select agents and toxins; examples include the organisms that cause Ebola, smallpox, anthrax and plague, and the poison ricin.

The lab is probably (in reality &main purpose) a bio-weapons type.
Na only America and China ..., Between these 2, that probably caused a lot a diseases at these point in the history of the world.
