The smallest infectious agents are viruses, particularly those like the Picornaviruses, which can be as small as 20 to 30 nanometers in diameter. These tiny particles consist of genetic material (either DNA or RNA) surrounded by a protein coat and cannot replicate on their own, requiring a host cell to reproduce. In comparison, bacteria and fungi are generally much larger in size.
Alzheimer's Disease is not known to be caused by an infectious agent. The disease's cause is still being investigated. Even if it were caused by an infectious agent, it would not likely be used for bioterrorism because the disease process tends to be slow.
