Smallpox
Rinderpest and Smallpox are the only two in history to be considered fully wiped out, although there are some samples of the Smallpox virus being stored in a lab.
In the TV show "Deadwood," smallpox spreads through the town. This plot thread occurred in the first season, which aired in 2004.
One potential biological warfare agent that is a virus is smallpox. It is highly contagious and has the ability to cause severe illness and high mortality rates within populations. Its aerosolized form can potentially be used as a weapon to infect large numbers of people.
An English doctor by the name of Edward Jenner. He noticed that milkmaids got cowpox which was similar to smallpox, but much milder, and after a milkmaid had had cowpox, she did not get smallpox. So Dr Jenner tried to scratch the skin of volunteers with a needle dipped in to cowpox germs. The volunteer got a transient mild illness and did not get smallpox after vaccination. When Dr Jenner's vaccine was shown to be so effective, vaccination against smallpox became compulsory. Smallpox is now almost entirely eradicated and most counties stopped making smallpox vaccination compulsory in the late 70s and early 80s.
Smallpox is a strictly human disease, it is not carried by animals. It is also extinct in the wild, although laboratory samples still exist.
Smallpox, influenza, malaria, measles, typhus and syphilis were brought to the Americas
Smallpox no longer exists in most MEDC's in the UN
Variolation was an early method of immunization against smallpox, where material from a smallpox sore was introduced into the skin of a healthy person. The purpose was to induce a mild form of the disease, leading to immunity without causing severe illness or death. This practice helped reduce the mortality rate associated with smallpox and laid the groundwork for the development of the modern smallpox vaccine. Variolation was instrumental in the eventual eradication of smallpox.
