Introduction to the Viruses Viruses cause a number of diseases in eukaryotes. In humans, smallpox, the common cold, chickenpox, influenza, shingles, herpes, polio, rabies, Ebola, hanta fever, and AIDS are examples of viral diseases. Even some types of cancer -- though definitely not all -- have been linked to viruses.

- Herpes – Herpes is a group of several viruses that infect humans. Diseases caused by the herpes viruses include cold sores, genital herpes, chickenpox, and shingles. Herpes viruses are spread between people by way of body fluids, through the air, and through contaminated objects and surfaces.

Rheumatoid Arthritis  In-Depth Report 1 The flu viruses that normally circulate in pigs can infect people, but this is not common. 2  In 2005 and 2006, three cases of infection with flu viruses that normally circulate in swine (“variant viruses”) were reported in people.

What Is a Virus? A viral infection is a proliferation of a harmful virus inside the body. Viruses cannot reproduce without the assistance of a host. Viruses infect a host by introducing their genetic material into the cells and hijacking the cell's internal machinery to make more virus particles.

Cardiologist Compensation Report: 2013 About 10% of oncologists earn $500,000 or more; about 14% earn $100,000 or less. For employed physicians, compensation includes salary, bonus, and profit-sharing contributions. For partners, compensation includes earnings after tax-deductible business expenses but before income tax.

- Viral diseases are extremely widespread infections caused by viruses, a type of microorganism. There are many types of viruses that cause a wide variety of viral diseases. The most common type of viral disease is the common cold, which is caused by a viral infection of the upper respiratory tract (nose and throat). Other common viral diseases include: Chickenpox. Flu (influenza). Herpes. Human immunodeficiency virus (HIV/AIDS). Human papillomavirus (HPV). Infectious mononucleosis.

Virus A virus is a microscopic parasite which can infect living organisms and cause disease. It can make copies of itself inside another organisms cells. Viruses consist of nucleic acid + a protein coat. Usually the nucleic acid is RNA; sometimes it is DNA.

- 1 Although there are no products with specific label claims against the Ebola virus, enveloped viruses such as Ebola are susceptible to a broad range of hospital disinfectants used to disinfect hard, non-porous surfaces.2  In contrast, nonenveloped viruses are more resistant to disinfectants.bola viruses are transmitted through direct contact with infected blood or body fluids/substances (urine, feces, vomit) or through exposure to objects (such as needles) that have been contaminated with infected blood or body fluids. The role of the environment in transmission has not been established.

Many serious diseases such as Ebola virus disease, AIDS, avian influenza, and SARS are caused by viruses. The relative ability of viruses to cause disease is described in terms of virulence.ome viruses cause no apparent changes to the infected cell. Cells in which the virus is latent and inactive show few signs of infection and often function normally. This causes persistent infections and the virus is often dormant for many months or years.

The relative ability of viruses to cause disease is described in terms of virulence.ther viruses, such as rabies virus, can infect different species of mammals and are said to have a broad range. The viruses that infect plants are harmless to animals, and most viruses that infect other animals are harmless to humans.

- Viral Infection Types. Animal viruses cause various types of infection. In lytic infections, the virus will break open or lyse the host cell, resulting in the destruction of the host cell. Other viruses may cause persistent infections.In this type of infection, the virus may go dormant and be reactivated at a later time. The host cell may or may not be destroyed. Some viruses can cause persistent infection in different organs and tissues at the same time.iruses gain entry into host cells via several sites such as the skin, gastrointestinal tract, and respiratory tract. Once an infection has occurred, the virus may replicate in host cells at the site of infection or they may also spread to other locations.

Human Immunodeficiency Virus (HIV) Human immunodeficiency virus (HIV) facts. The human immunodeficiency virus (HIV) is a type of virus called a retrovirus, which can infect humans when it comes in contact with tissues that line the vagina, anal area, mouth, or eyes, or through a break in the skin.

Viruses: Viral Structure, Replication and Function In addition, in order to spread the viruses also need to withstand the immune system. A special category of viruses is those that cause disease only when the immune system is deﬁcient in some way; these are called opportunists, and opportunistic infection is one of the main problems in patients with, for example, AIDS. special category of viruses is those that cause disease only when the immune system is deﬁcient in some way; these are called opportunists, and opportunistic infection is one of the main problems in patients with, for example, AIDS.

How viruses infect bacteria: A tale of a tail Bacteriophages are viruses that infect bacteria. Using state-of-the-art tools, scientists have described a million-atom 'tail' that bacteriophages use to breach bacterial surfaces. The breakthrough has major implications for science and medicine, as bacteriophages are widely used in research.

bacterial virus More than 400 types of viruses that cause a great variety of illness are known. All of them can attach to cell membranes, enter the cytoplasm, take over cellular functions, reproduce their parts, and assemble themselves into mature forms capable of infecting other cells.

Virus A virus is a small infectious agent that replicates only inside the living cells of other organisms. Viruses can infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea.he viruses that infect plants are harmless to animals, and most viruses that infect other animals are harmless to humans. The host range of some bacteriophages is limited to a single strain of bacteria and they can be used to trace the source of outbreaks of infections by a method called phage typing.

Viruses: Viral Structure, Replication and Function Virus spread control. Viral diseases can be prevented from spreading by vaccinations and the most successful of these is the small pox vaccine that has completely eradicated the disease in 1980. It is hoped that several other viruses, such as polio and measles, will follow. special category of viruses is those that cause disease only when the immune system is deﬁcient in some way; these are called opportunists, and opportunistic infection is one of the main problems in patients with, for example, AIDS.

Information on the different types of viruses and types of viral infections A virus is a tiny organism that causes an infection in the body. Viruses are made up of the genetic material known as DNA or RNA, which the virus uses to replicate. In order for a virus to survive, it must invade and attach itself to a living cell.hen the cell dies, new types of viruses are released, and they infect other cells. This is how viruses cause disease. Generally, viruses will only infect one type of cell. For example, the cold virus will only infect cells of the upper respiratory tract.

- Most Viral Host Ranges Are Narrow. The fact that the host range — the group of cell types that a virus can infect — is generally restricted serves as a basis for classifying viruses. A virus that infects only bacteria is called a bacteriophage, or simply a phage.
