Viral Infection
A Viral Infection (pronunciation: /ˈvaɪrəl ɪnˈfɛkʃən/) is a disease that can occur when an organism's body is invaded by pathogenic viruses. The viruses then multiply and often cause illness. Viruses are tiny organisms that may lead to mild to severe illnesses in humans, animals and plants. This may include flu or a cold to something more life threatening like HIV/AIDS.
