Viruses and Infections

Submit Abstract Register Now

Viruses are capsules with genetic material inside. Viruses are like hijackers. They invade living, normal cells and use those cells to multiply and produce other viruses like themselves. This eventually kills the cells, which can make you sick. Viral infections are hard to treat because viruses live inside your body's cells. They are "protected" from medicines, which usually move through your bloodstream. Antibiotics do not work for viral infections. There are a few antiviral medicines available. Vaccines can help prevent you from getting many viral diseases. When the body's immune system detects a viral infection, it begins to respond in a generic way. A process begins called RNA interference, which is crucial to fighting viruses because it degrades the viral genetic material and enables cells to survive the infection. Whereas bacterial infections can be treated with antibiotics, viral infections require either vaccinations to prevent them or antiviral drugs to treat them. Types of some viral diseases are Ebola, HIV, HPV, Influenza, Herpes Virus, Small Pox, Hanta Virus, etc.
