The most lethal contagions are no longer WMD's, they are WMC, weapons of mass casualties, that can overtax medical treatment facilities. These include smallpox, Ebola, bird flu, Rift Valley Fever, anthrax, septicemic plague, and Marburg virus (Lake Victoria virus, hemorrhagic fever).

No- it is an entirely different disease, but both were very devastating to the population when epidemics broke out, killing millions of people.
The black plague was carried by the fleas of infected rodents. In most of the countries today, this type of transmission is rare. The plague also killed two-thirds of its victims within four days, which is similar to the Ebola virus.
The smallpox vaccine comes from cows. Most diseases you a weakened form of the disease. However the smallpox vaccine is brought from cowpox. (closely related to smallpox but not as dangerous). You cannot get this vaccine anymore and if you did it would result in a bad reaction.
One of the most common epidemics is influenza. Other epidemics include: plague, measles, smallpox, HIV/AIDS, SARS, and meningitis.
The Europeans carried deadly diseases into America killing most of the native population. The most deadly of these diseases were typhus, measles, Bubonic Plague, malaria, and smallpox. In the early 1700s, smallpox wiped out half the Cherokee. In the early 1800s, it wiped out two-thirds of the Omaha and all the Mandan people. Smallpox killed at least half of the west native population.
It depends on what you mean by "most deadly". Some diseases, like the Bubonic Plague, killed more people than, say, smallpox, but is more easily treatable. The reason the plague killed more people is because it became a pandemic during the middle ages, when medical treatment was unavailable. Some of the deadliest, however, are: Bubonic Plague Smallpox Anthrax Tuberculosis
This will be a matter of opinion.Rabies 99.99% fatal in all advanced cases but you can be vaccinated which makes it ignorable.Hanta virusThe black plague and Ebola are bacteriaMalaria is a parasite.
Ebola is caused by one of four Ebola viruses: Ebola Zaire (most deadly), Ebola Sudan, Ebola Cote d' Ivoire, and Ebola Reston (found in Virgina, US, not deadly to humans)
Smallpox was by far the most dangerous disease, for native Americans, once it was introduced to the western hemisphere by European colonists.
Plague was most commonly transmitted by fleas and rats.
