- Smallpox is a deadly and highly contagious disease caused by Variola major, a double-stranded DNA orthopox virus. It has been a major cause of death throughout history, killing more than 500 million people in the 20th century. For comparison, the current population of the United States is a little over 300 million.

- As of April 14, 1978, no cases of smallpox have been reported to the World Health Organization (WHO) from anywhere in the world since the last case had onset of rash on October 26, 1977, in Merka town, Somalia.f no more cases of smallpox are detected, the countries of Somalia, Ethiopia, Djibouti, Kenya, Yemen, and Democratic Yemen will be eligible for certification in October 1979.

Cowpox Cowpox is similar to, but much milder than, the highly contagious and often deadly smallpox disease. Its close resemblance to the mild form of smallpox and the observation that dairymaids were immune from smallpox inspired the first smallpox vaccine, created and administered by English physician Edward Jenner.

- 1 Smallpox: Smallpox is a serious, contagious, and sometimes fatal infectious disease caused by the variola virus. 2  Historically, smallpox had a mortality rate of as much as 30 percent. 3  In the Americas, it killed as much as 90 percent of the indigenous population after contact with Europeans introduced the disease.

- Bananas produce ethylene gas, a hormone that triggers ripening. Keep them in a paper bag to trap more of this gas near the fruit. 1  Avoid paper bags with a clay or waxy coating, which may absorb the ethylene.  A plastic bag blocks oxygen from reaching the fruit, which can sometimes lower the production of ethylene.

Smallpox Smallpox is an infectious disease of the past that was eliminated by vaccination. The disease was caused by the variola virus, which spread from person to person. Affected people became very ill with a high fever and a characteristic rash. Up to one-third of people with smallpox died. Although the disease has been wiped out, samples of the virus still exist in high-security laboratories in the United States and Russia. This has led to concerns about use of the virus in biological warfare.

- The smallpox virus is said to have emerged about 10 thousand years BC. The virus' genes suggest that it was once a rodent virus that made its trans-species jump into humans in one of the early agricultural river valleys. Smallpox is thought to have rooted itself early in people living in the river valleys of China.mallpox is a virus. 8 people found this useful. 1  Side Effects of the Smallpox Vaccine Smallpox is an infectious disease that can cause severe skin disfigurement with the manifestation of large blisters that can cover the entire body.

Smallpox The U.S. military uses a smallpox vaccine called ACAM2000, produced by Sanofi Pasteur. The virus in ACAM2000 is produced not on the flanks of cows, as with previous generations of vaccine, but in lab cultures of African green monkey cells.

The Science of Smallpox 1 [anno: The smallpox virus normally enters the body through the respiratory system. 2  Smallpox can cause millions of cells within the body to explode. 3  If too many cells explode, entire organs could fail, and a person could die. 4  Smallpox also lives on in the blood after a person has died.mallpox is spread when a person breathes it in…and out. The virus gets inside the cells lining the throat and hijacks the cellular machinery to make millions more smallpox viruses. The cells explode, releasing smallpox “bombs.” Those virus particles go on to infect other cells in the body.

Smallpox Smallpox is a contagious and sometimes fatal disease caused by two related viruses: variola major and variola minor. Variola major is the more common and severe form, with an overall historical fatality rate of about 30%. Variola minor is less common and causes a milder form of smallpox that is usually not fatal. Historic death rates were less than 1%. Smallpox eradication was one of the greatest successes of modern public health.

- (See escape from the host cell below).SmallpoxThe most famous poxvirus is the smallpox virus. (Chicken pox is not caused by a true poxvirus, but rather by Varicella, or varicella zoster virus (VZV), a member of the herpesvirus family). The 3’ end of one strand is opposite the 5’ end of the other complementary strand. 2  DNA polymerase (DNA-dependent DNA polymerase) reads the template strand in the direction 3' to 5‘ and so synthesises a new complementary strand which grows in the 5’ to 3’ direction.

- Smallpox is a serious, contagious, and sometimes fatal infectious disease caused by a virus called the variola virus. The disease gets its name from the Latin word for spotted and refers to the small pus-filled blisters that appear on the face and body of an infected person.mallpox is spread from person to person by several means, including: 1  Direct, face-to-face and fairly prolonged contact with an infected person – the saliva of the infected person can spread the disease. 2  Direct contact with the fluid in the blisters in the infected person’s skin or other infected bodily fluids.

Smallpox Smallpox is a disease caused by a poxvirus that is transmitted from person to person that causes high fever, characteristic rash, and may kill about one-third of those infected. Smallpox (also called variola) is the only disease that has been completely wiped out throughout the world. Smallpox is also potentially one of the most devastating biological weapons ever conceived. Due to the success of an intense worldwide public health initiative, not one documented naturally occurring case of this highly infectious, deadly disease has occurred since Oct. 26, 1977.

- Smallpox is a serious infectious disease caused by the Orthopox virus, variola. The last case in Vermont occurred in 1937, and there have been no confirmed cases worldwide since eradication was achieved in 1978.A single case today would be considered a national public health emergency.mallpox spreads from person to person mainly by aerosolized droplets that come from the coughing of infected patients. Contact with smallpox scabs or contaminated clothing or linens can also spread the disease.

Smallpox Variola (the virus that causes smallpox) is a member of the orthopoxvirus genus, which also includes viruses that cause cowpox, monkeypox, orf, and molluscum contagiosum. Poxviruses are the largest animal viruses, visible with a light microscope.They are larger than some bacteria and contain double-stranded DNA. Poxviruses are the only viruses that do not need a cell's nucleus to replicate inside the cell. The variola virus is the only known cause of smallpox.The disease affects only humans. Types: Variola major, or smallpox, has a death rate of 30%. 2  Variola minor, or alastrim, is a milder form of the virus with a death rate of 1%. 3  Four types of variola exist: classic, hemorrhagic, malignant, and modified.

- The Variola virus, which is the most virulent member of Genus Orthopoxvirus, is the causative agent of smallpox. It specifically infects humans. The primary reason for infection in humans is due to its ability to evade the host immune responses, and avoid complement activation.he only other choice is prevention through the use of the vaccine (Mayo, 2002). The smallpox vaccine is a live vaccine, derived from the vaccinia virus. The vaccine does not contain or cause a variola infection.
