Smallpox is a strictly human disease, it is not carried by animals. It is also extinct in the wild, although laboratory samples still exist.

According to Wikipedia, smallpox can be spreaded by direct contact with infected skin. Coughing, sneezing, speaking and even breathing can spread the virus through saliva droplets expelled from the mouth.

Probably a lot of them, but the first one that comes to my mind is the Susquehannock of the Pennsylvania region.

Part of the story involves General Amherst and Colonel Bouquet deciding to distribute to local American Indians blankets from Fort Pitt (which had a smallpox outbreak while it was under seige). I don't recall immediately if that was the cause of the Susquehannock case, but there is significant documentation on this actually happening. The original letters between Amherst and Bouquet still exist. You can find more about what happened around the web.

He noticed that milkmaids who had suffered from cowpox didn't suffer smallpox, this lead him to believe that the cowpox prevented smallpox. He tested this on James Phipps, he infected the boy with pus from a milkmaids cowpox boil, he caught cowpox. Jenner then infected the boy with smallbox, but Phipps didn't catch it. This was the first inoculation. Jenner was given grants to find other inoculation's, but failed as he was unsure why immunity was given. It wasn't till Pasteur's (anthrax and rabies vaccines) time that other vaccines were discovered.

Technology helped Smallpox because they invented the needle to cure it with, at least that's what my primary school teacher taught me!! Yeah i think they did invent the needle because a young boy was tried out with it first to see if it would work.

Small pox was eradicated because many countries suffered greatly from it and it had a 30-40% kill rate. Many of the industrialized countries (U.S., U.K., Sweden) feared infected people coming into their country and infecting their population.

for you're safety of not getting smallpox.

this is a disease that is contagious through viral infections, or it is caused by viral infections

1853

300,000 in the UK, not sure about the rest of the world though. 300-500 million died during that century and the same for the next. Up to 80% of infected children died of the disease. Vaccinations reduced these deaths to 0 by 1979.

Edward Jenner made a vaccination out of pus from one of the blisters of a person with smallpox

It turns out that smallpox actually is a nickname. It is used to refer to the virus, Variola, which may appear as V. major or V. minor. You'll find a link below if you wish to do some review of this unique-to-human infectious disease. It's been with us a long, long time, so why not take a couple of minutes to at least read the first couple of paragraphs about this not-so-friendly visitor upon us?

Smallpox no longer exists in most MEDC's in the UN

The devil is in the details of exactly what you are referring to here. Do you mean: Can a person who has been vaccinated against smallpox then catch it at a later date, and while not getting sick from it, transmit it to others? Ans: In general, no. The vaccination not only keeps you healthy, but stops the virus in your body. Can a person who has recently been vaccinated against smallpox pass on smallpox to someone else? Ans: No, we don't use weakened variola virus (smallpox virus) to inoculate people. Can a person who has been recently vaccinated against smallpox using the standard live vaccinia virus type vaccine pass on a vaccinia virus infection to other people? Ans: Yes! And, it can be dangerous. That's why people should be careful with their fresh smallpox vaccination wounds. Can a person who has been recently vaccinated with the newest MVA-type smallpox vaccinations pass on a vaccinia infection on to others? Ans: No. At least theoretically not. But, it's so new, we can't say for absolute certain.

Janet Parker, a British medical photographer, died of smallpox in 1978, ten months after the disease was eradicated in the wild, when a researcher at the laboratory Parker worked at accidentally released some virus into the air of the building. She is believed to be the last smallpox fatality in history.

Well, I think it is the case that cowpox is just a lesser, bovine version of smallpox. Milk maids would get cowpox simply because they were exposed to cattle constantly, much more than the average person, who was more likely to get smallpox than cowcox.

A scientist called Edward Jenner observed that milk maids, who often got cowpox, never seemed to get smallpox. This was because milk maids would develop immunity to cowpox (and therefore smallpox) once they had fallen ill and recovered from cowpox. He then tested this theory on a young boy. He did this by injecting cowpox into the boy's blood stream; the boy then fell ill with cowpox. After the boy recovered from cowpox, the scientist then injected him with the life-threatening disease smallpox. The result proved his theory right; the injection of smallpox into the boy's bloodstream had had no effect on him, because his body had developed immunity to the disease.

If you wish to learn more about vaccination and immunities, then research antibodies, antigens and vaccination and the way in which they all work.

Small Pox is an infectious disease, so you'd think there would be a high risk, but, a vaccination for Small Pox was created and now Small Pox has been almost 100% eradicated except for a few chemical labs that dot the world.

There is no effective medicine. A vaccine is used to prevent it. Jenner made the first ever vaccine for smallpox!

In October 1562 Elizabeth I caught smallpox, but survived it.
