Viral Infections Directory
Viruses cause all types of infections and diseases. Some of the most common viral infections are the common cold, the flu, and warts. Some of the more severe diseases that viruses cause are HIV/AIDS, smallpox, and hemorrhagic fevers like Ebola and Marburg. In order for viruses to cause an infection, they must take their genetic material and hijack normal, living cells to produce more viruses with the same genetic material. Since viruses live inside cells of the body, they are hard to kill. But there are vaccines that can protect humans from many viral infections. Learn more about various viral infections and vaccines.
Bacterial vs. Viral Infections: Causes and Treatments
What’s the difference between a bacterial and viral infection? WebMD explains, and provides information on the causes and treatments for both.
A viral test is done to find infection - causing viruses. Viruses are one of the smallest organisms and, unlike bacteria, they multiply only within living cells.
Newcastle Disease Virus (PDQ®): Complementary and alternative medicine - Patient Information [NCI]-Questions and Answers About Newcastle Disease Virus
What is Newcastle disease virus?Newcastle disease virus (NDV) is a virus that causes a deadly infection in many kinds of birds. In humans, NDV causes mild flu-like symptoms or conjunctivitis (an infection of the eye that is also called pink eye) and/or laryngitis (an irritation and swelling of the voice box and the area around it).Like other viruses, NDV infects cells (called host cells) and then uses those cells to replicate (make copies of) itself. Researchers are interested in NDV because it replicates itself more quickly in human cancer cells than in most normal human cells and it can kill the host cells. For these reasons, the virus is being studied as a treatment for cancer. What is the history of the discovery and use of Newcastle disease virus as a complementary or alternative treatment for cancer?The first report that NDV may be useful as a cancer treatment was published in 1964. For 20 years before this report, NDV was used in a vaccine to prevent Newcastle disease in birds.
Newcastle Disease Virus (PDQ®): Complementary and alternative medicine - Patient Information [NCI]-General CAM Information
Complementary and alternative medicine (CAM)—also referred to as integrative medicine—includes a broad range of healing philosophies, approaches, and therapies. A therapy is generally called complementary when it is used in addition to conventional treatments; it is often called alternative when it is used instead of conventional treatment. (Conventional treatments are those that are widely accepted and practiced by the mainstream medical community.) Depending on how they are used, some therapies can be considered either complementary or alternative. Complementary and alternative therapies are used in an effort to prevent illness, reduce stress, prevent or reduce side effects and symptoms, or control or cure disease. Unlike conventional treatments for cancer, complementary and alternative therapies are often not covered by insurance companies. Patients should check with their insurance provider to find out about coverage for complementary and alternative therapies. Cancer patients
