What are the symptoms of smallpox?

smallpox, a disease caused by a Variola virus, is one of the largest killers in terms of disease in history. Symptoms of smallpox include fever, pain and raised pustules on the skin, which are uhroliš above and often leave disfigurement scars. It is assumed that smallpox, also known as Varola, was eliminated by a successful vaccination campaign, except for several samples led in the laboratories under the lock and key. During this time there are no smallpox symptoms and the individual is not contagious. This is followed by two to four days of symptoms of similar flu: high fever, pain and sometimes vomiting.

soon after the face and nose and mouth appear a rash of red spots. They spread into the hands and feet, then into the whole body in a few days. Shortly thereafter, the flat red spots turn into raised pustules that are filled with liquid and develop a crater or depression. The "POX" in smallpox concerns these lesions.

After about two weeks of holding this rash, impact rattle. Shaby then fallenU and leaves scars. If the individual survives until all scabs fall, they are most likely to be without illness and are no longer contagious.

SMALPOX has two forms: variojor and varola minor. Both are similar, in addition to the fact that in the case of a smaller vario, the symptoms of smallpox are much less severe. Overall, the rate of mortality is about 30%; The rate of Variola Minor death is about 1%.

Major Varoli can be further divided into four categories: ordinary, modified, flat and hemorrhagic. Modified smallpox occurs in individuals who have already been vaccinated and are usually less severe. For flat smallpox, the spots of smallpox remain flat and soft before they develop into the characteristic hard, raised bumps. Hemorrhagic enamelox is accompanied by massive bleeding into the skin and mucous membranes that can occur before or after the appearance of the rash. Flat and haemorrhagic smallpox are almost always fatalof it.

It is assumed that smallpox unfortunately only affects people, and there seems to be no groups of people with natural immunity to the disease. No successful treatment of smallpox has ever been found, but at the beginning of the 18th century, the process of vaccination was discovered by Greek physician Emanuel Timoni. Englishman Edward Jenner created a much more viable vaccine with a Cowpox virus later in the century.

In the 20th century, the World Health Organization (WHO) led the campaign to eradicated smallpox using vaccines. The last known patient showing symptoms of smallpox outside the laboratory was in Somalia in 1977. Extensive vaccination for smallpox is no longer. Some fear that the disease could be re -introduced into the world as a biological weapon, with quoting the experiments of World War II several world governments to do it. For this reason, Russian and the United States governments retain samples of disease to carry out future research.
