Variola Virus Research Paper

Smallpox is a viral infection caused by Variola major. This infection is currently one of the most dreaded diseases, and is believed to be more dangerous than the enemy’s sword. The exposure is usually an infection of the respiratory tract. After exposure, early symptoms are: headaches, back aches, fever, vomiting, discomfort, and feeling out of sorts. These symptoms go away usually in two days, and the patient feels better. Then about two days later, the patient has a flustered face, and lesions on the mouth, throat, and nasal membranes. At 5 days past exposure, red rashes and bumps appear on the skin, bleeding through skin, and mucous membranes. If the patients bleeds through their eyes, gums, or nose, the patient will not live much longer, but that is not usually the case. The bumps may touch each other or they may be separate from each other. If the bumps do not touch, the patients has a good chance of surviving. But if the bumps do touch, the patient has a forty percent chance of surviving. Dehydration is common in patients because it may be painful or difficult to drink. Around day ten, the bumps will become soft, and blisters will form. The fluid in the bumps is absorbed because of dehydration. A smell often comes from cracked bumps, and a second bacterial infection may occur due to the openings in the body. Two weeks after initial symptoms, the bumps and blisters are replaced by scabs. One week later the fever disappears, the patient returns to a normal life, and the

Smallpox is a virus that was first founded in ancient times. The virus?s proper name is Variola rex, and it has various different forms as well as various symptoms. Among these forms are typical smallpox, hemorrhagic smallpox, and malignant smallpox, all of which usually always cause death in their victims. Some of the typical symptoms of smallpox include red vesicles and pustules all over, bleeding from all orifices of the body, swelling in the face, throat, and eyes, difficulty eating and swallowing, delirium, malaise, deterioration of the bone marrow, lymph nodes and mucus membranes of the body, and a multitude of other secondary symptoms. Smallpox is typically diagnosed by ruling out the possibility of other

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.

There are a couple symptoms to smallpox, mostly affecting your skin. The first couple of days, it will begin with normal symptoms of a fever. Eventually, there will be body aches, headaches, and you will begin to feel weaker. Small, round blisters appear all around the body. Within a week, the pox becomes filled with pus and gets bigger. Then eventually, the blisters crust and stomach pains will most likely occur. Within the next couple of weeks, the blisters become scabs and they fall off, which result in scars on the skin. You could get scars, blindness and your hands and feet could get deformed. The scars stay on your body.

Smallpox comes from variola major virus. It is transmitted through inhalation by droplet infection (contact with contagious body fluids). Individuals can also become infected through direct contact with contaminated clothing or bedding. There are two types of smallpox. The Variola virus; major and minor. The more deadly form of the virus, Variola major, generally killed up to twenty five percent of the people infected and accounted for over ninety percent of all cases (Sherman, 2007). Populations that had never been exposed to the virus would however have fatality rates that would exceed fifty percent. The Variola minor pathogen had a rate of death that was much lower. At two percent it was more common in Europe in the17th century before the deadlier pathogen of the virus was reintroduced. It then became a common and

Requires a medical diagnosis In addition to flu-like symptoms, people experience a rash that appeared first on the face, hands and forearms. People may experience: pain Skin: rashes, small bump, blister, scab, or scar Whole body: fever, malaise, or chills Also common: headache or vomiting After exposure to the smallpox virus, it usually takes 7-17 days until illness begins. Smallpox generally begins with fever, headaches, body aches, and weakness on day 1. Then: Day 2-3: small, round pox (blisters) appear and spread on the face, arms, legs, and inside the mouth Day 7: the pox turn into bigger blisters and fill with pus Day 12: the blisters crust over; stomach pain and confusion can also occur Week 3-4: the blisters turn into scabs and fall

This disease has one of the largest virus and most complex virus particles, also known as virions, found in nature. Smallpox is caused by the Variola virus. It’s called Variola which comes from the Latin word Varius, meaning spotted (Preston 237). Smallpox is part of the genus, Orthopoxvirus. Orthopoxviruses are viruses that usually use vertebrates and mammals as hosts. Viruses in this group include Buffalopox, Camelpox, Monkeypox, Mousepox, Rabbitpox and Raccoonpox. These diseases are usually named after their primary host, the only exceptions being Cowpox and Monkeypox, which are typically carried by rodents. Despite Chickenpox’s name, Chickenpox is part of a completely different group and isn’t related (Tucker 5). Another form of Smallpox is Hemorrhagic Smallpox, also known as Blackpox. It’s very rare, but very deadly having an almost 100% mortality rate (Preston 44-50). These variants are all very unpleasant, but one stands out above all other, and has some terrible symptoms:

rate of about 30%. Variola minor is a much less common form with an estimated death rate of less than 1%” (Derm). Variola Major can be further split into 4 forms of smallpox that being. Ordinary which is the most frequent form seen around the world with over 90% of cases being diagnosed. Modified which is a milder type of smallpox however it is rarely fatal. “Flat-type smallpox which accounted for about 6% of cases in the pre-eradication era

Small pox is an infectious rash of little round blisters they could be found on the legs arms and face. Small pox is caused by a deadly virus known as the Variola virus. There has not been a small pox case in the U.S since 1949 but the last known case was in Somalia in 1977. Vaccinations have wiped out the virus but not all of it. Two facilities one in the U.S and one in Russia. You cant get a vaccination any were. The virus is spread not by animals but by other people by someone touching the infected area or breathing in the same air in a small place like a plane or a bus or if you touch something that someone else has

The vaccine for Smallpox worked so well that there hasn’t been any cases of Smallpox in 66 years (since 1949). The world’s last known case of Smallpox was in Africa in 1977. The World Health Organisation (WHO) declared that Smallpox was eradicated from the world in 1980. Smallpox was the first infectious disease in history that was announced

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

Smallpox is a transmittable disease, and a deadly one that has affected humans for thousands of years, also known as Variola. It was developed worldwide in 1980. Currently there are no treatments or cure are available for smallpox, although the vaccination’s side effects is too risky for the people who are at low risk to the deadly virus. The symptoms of smallpox will appear around twelve to fourteen days after the person received the disease. A person who has been incubated will stay there from seven to seventeen days. They will look and feel healthy and cannot spread the disease to others. During the incubation period the signs and symptoms include, fever, headache, severe fatigue, vomiting, and discomfort. After a couples days a red,

The vaccine was discovered back in 1796 by the English physician and scientist Edward Jenner. Little did he know that he just made one of the most important discoveries in human existence. The vaccine consisted of cowpox pus that he later injected into to a little eight year old boy, James Phillips. After 2 week the boy had recovered from the cowpox and when exposed to smallpox, his body was not affected. The scientist was amazed and later on conducted an experiment which consisted of 12 people being inoculated with cowpox pus and later on exposed to the deadly disease of smallpox. Sir Edward Jenner concluded, “that the cow-pox protects the human constitution from the infection of smallpox”.This laid the foundation for modern vaccinology. The

Smallpox began in India or Egypt at least 3,000 years ago. Smallpox has spread around the world.Authorities can’t do much about about smallpox but what they did do is allow an injection to prevent smallpox from happening.

There are several different kinds of communicable diseases in today’s society. Smallpox happens to be one. Smallpox is considered to be a contagious, and fatal infectious disease. Smallpox has been existence for over 200 years, and the first known outbreak strated in Eruope and traveled to India and parts of Asia. “The pox part of smallpox is derived from the Latin word for “spotted” and refers to the raised bumps that appear on the face and body of an infected person,” (CDC, 2016, para 1). Smallpox is caused by the Variola virus. There are two clinical forms of smallpox, Variola major and minor. The most common form of smallpox is Variola major which is the most severe. “The last case of smallpox in the United States was in 1949. The last
