Viral Infectious Diseases
Viruses are very tiny germs. They are made of genetic material inside of a protein coating. Viruses cause familiar infectious diseases such as the common cold, flu and warts. They can affect your whole body with all over muscle soreness and fever. They invade normal living cells and use those cells to multiply and produce other viruses like themselves. Viral infection is contagious than bacterial infections. Most viral infections last from several days to 2 weeks as long as the virus affects the body. Vaccines can reduce the risk of acquiring some viral illnesses and help protect against the flu, hepatitis A, hepatitis B, chickenpox, herpes zoster (shingles), cancer-causing strains of human papillomavirus (HPV), measles/mumps/rubella (MMR), polio, rabies, rotavirus, and other viruses.
