Cowpox Cowpox is a skin disease caused by a virus known as the cowpox virus. Cowpox is transmitted by touch from infected animals to humans. Cowpox is similar to but much milder than the highly contagious and sometimes deadly smallpox disease. Cowpox resembles mild smallpox. Cowpoxes symptom is red skin blisters

Period 7 Are Viruses Alive? For many years there have been numerous controversies over whether a virus should be classified as living or nonliving. It is believed that viruses are considered nonliving because they lack a substantial amount of qualities to be classified a form of life and they are incapable of carrying out all life processes. For example‚ some characteristics that would justify a virus being nonliving would be that they are acellular: they are not made up of cells nor do they contain

The Ebola Virus INTRODUCTION The most deadly killers on this earth are too small to see with the naked eye. These microscopic predators are viruses. In my report‚ I will answer many basic questions concerning one of the fastest killing viruses‚ the Ebola virus. Questions such as "How does it infect its victims?"‚ "How are Ebola victims treated?"‚ "How are Ebola outbreaks controlled?" and many others related to this deadly virus. GENERAL INFORMATION The Ebola virus is a member of the negative

What is the Zika virus? The Zika virus comes from a daytime active Aedes mosquitoes. This virus was first identified in Uganda in 1947‚ first found in monkeys then later on found in humans in 1952. Zika had its first outbreak on an island in Yap in 2007‚ as of now we know that many countries are experiencing these same outbreaks. It’s found in mostly tropical climates which is why you can find it in Rio. This summer the olympics were held in Rio‚many of the Athletes didn’t travel and compete because

RABIES Abstract: Each year‚ approximately 55‚000 individuals worldwide die from an infection due to the rabies virus. Rabies is a life-threatening disease caused by an RNA virus that is usually transmitted to humans through bites from rabid animals. More recently‚ reports of transmission by means of organ transplantation have been reported. Since human rabies is nearly 100% fatal if prophylactic measures are not followed‚ an increased awareness of who should receive prophylaxis and

Food Borne Illness In my findings of the virus known as Norovirus‚ it is also referred to as Gastroenteritis. The virus is caused by influenza. The Norovirus affects thousands of people every year according to the Centers for Disease Control (CDC). The Norovirus is a member of a category known as Calcivirus family. The virus is made up of four groups. The Norovirus is the most important virus to human pathogens. According to scientist the Calcivirus is difficult to study due to their

Measles Virus In the 1800’s the measles was a very dangerous disease‚ and when people who come in contact with it will die‚ if they have never been exposed to the virus before. The measles is transmitted through the air. The way that the virus is transmitted is that infected droplets are released by coughing‚ sneezing‚ and by talking. When the infected droplets that contain the measles are in the air‚ they are taken into the body through the mouth‚ nose and eyes of the potential person that

Viruses: Structure A virus particle‚ also known as a virion‚ is essentially a nucleic acid ( HYPERLINK "http://biology.about.com/od/geneticsglossary/g/DNA.htm"DNA or RNA) enclosed in a protein shell or coat. Viruses are extremely small‚ approximately 15 - 25 nanometers in diameter. Viruses: Genetic Material Viruses may have double-stranded DNA‚ double-stranded RNA‚ single-stranded DNA or single-stranded RNA. The type of genetic material found in a particular virus depends on the nature and function
