What Is Molluscum Contagiosum?

The biological significance of this article is due in part to the fact that viruses are being considered as partway-living things. Even though they are only halfway living, per se, they are still an important part of the study of living things because of the unique way in which they “live” and continue to reproduce by taking advantage of host cells. The information in this article relates to biologists in that viruses provide an entirely different element of potential life, as they are a cause for reconsideration when it comes to defining and determining life and non-life forms. This

* Flaviviruses: share a common size (40-60nm), symmetry (enveloped, icosahedral nucleocapsid), nucleic acid (positive-sense, single stranded RNA approximately 10,000-11,000 bases), and appearance in the electron microscope. Therefore, images of West Nile virus are representative for this group of viruses.

A virus is a small capsule that contains DNA or RNA, viruses, unlike bacteria are not self sufficient and need a host in

Smallpox virus's scientific name is variola. It means "spotted" in Latin, and it was given to the disease by a medieval bishop. The virus, as a life form, comes in two subspecies:

Because the smallpox virus attacks the mucus membranes, bone marrow, and lymph nodes of the body, most patients obtain the gruesome disfigurement of the face and nose and limbs.( Bollet

Smallpox is a highly contagious virus that has no known cure. Variola, is the name of the virus that caused one of the largest epidemics known to man. Smallpox killed nearly 500 million people in the 20th Century alone. Before Smallpox was eradicated it killed nearly 60% of all infected people. Smallpox has been coexisting with humans for thousands of years and has a very long history.

Despite smallpox’s long history of harm, killing nearly 300 million people in the twentieth century alone, it is now considered eradicated thanks to a vaccine and vaccination program lead by the World Health Organization. Because of its eradication,

Smallpox is a highly contagious infectious disease. The type of microbe for smallpox is the Variola virus. Smallpox is caused by either the Variola major or the Variola Minor. This virus is spread by direct contact. The disease was likely to be in human populations about 10,000 BC. An epidemic broke out in 1519 with the Aztecs and the Conquistadors in Tenochtitlan Mexico. The epidemic killed a total of twenty five percent of the Aztecs population leaving it easy for Cortes and the conquistadors to take over the desired

Smallpox was once one of the most severe infectious diseases that was endemic throughout the world for most of the recorded history. It is caused by variola virus (a DNA virus and a member of the Poxviridae family), and characterized by three phases: incubation, prodrome and rash. This disease killed and disfigured innumerable millions of people globally.

Throughout history, diseases have been recorded. Some species were wiped out completely, while others learned to adapt. Small pox is one such disease that has the ability to completely destroy the human population.

Smallpox, an acute contagious disease, was one of the world's most devastating diseases known to humanity. Variola major and Variola minor are two recognized forms of smallpox. Both of them are double-stranded DNA viruses of the orthopoxvirus family. Compared to Variola minor, Variola major is more virulent with 30% of mortality rate and it has historically been more prevalent. Variola minor is considered rather mild with lower mortality rates. The pustular rashes on the mummified body of Pharaoh Ramses V of Egypt was probably the first physical evidence of smallpox. Earliest incontrovertible description of the smallpox occurred in year 581, Bishop Gregory observed and described some characteristic symptoms of the smallpox. In the 9th century,

Smallpox is caused by the virus variola, also known by its family name Poxviridae. It comes in four variola forms: ordinary, modified, flat, and hemorrhagic. The flat and hemorrhagic strains of smallpox are the most severe and usually result in death.

The earliest case of smallpox according to a journal published in the US National Library of Medicine titled, “Edward Jenner and the History of Smallpox and Vaccination” was recorded as early as 1122 BC. (Riedel “Smallpox the Origin of a Disease”). Mankind’s triumph over this horrible disease was initiated by an English doctor named Edward Jenner. Through observations and experimentation, Jenner would create a procedure now known as vaccination. (Riedel “Edward Jenner”). During the next two centuries, vaccinations would be used worldwide to stop the spread of small pox. After the successful worldwide vaccination campaign led by the World Health Organization, small pox was eradicated worldwide in 1980. As a result of the eradication of smallpox according

This deadly infectious disease is caused by either of two viruses, Variola major and Variola minor which were highly contagious. After exposure symptoms include fever, tiredness, headaches, and muscle aches. This is normally followed by rash or lesions that appear all over the body and face becoming raised with fluid/pus. Smallpox is highly contagious and can be transmitted through bodily fluid, close contact and even clothing/bedding material that came in contact with an infected person.

The 5’-terminus has a methylguanosine cap and the 3’-terminus consists of a poly(A) tail [7]. The genome contains five open reading frames (ORFs), see figure 1A.
