Viral Diseases, Virus and Human Diseases



To study about some of the common viral diseases.


  • Viruses cause many human diseases by killing host cells or disturbing their homeostasis.
  • Viruses are not affected by antibiotics. Several viral diseases can be treated with antiviral drugs or prevented with vaccines.


A virus may be characterised as “a part of bad data bound in protein.” Unlike bacteria and fungi, viruses are not living organisms; instead, they consist in essence of a length of nucleic acid-their transmitted particles-that is enclosed and shielded by a protein layer. The transmitted element of viruses is formed of one type of nucleic acid, which may be both ribonucleic acid (RNA) or deoxyribonucleic acid (DNA).

Viruses and Human Disease

Viruses cause many human diseases. In addition to the flu and HIV, viruses cause rabies, measles, diarrheal diseases, hepatitis, polio, cold sores and other diseases. Viral diseases range from mild to fatal. One way viruses cause disease is by causing host cells to burst open and die. Viruses may also cause disease without killing host cells. They may cause illness by disrupting homeostasis in host cells.

The Flu Viral Disease

Influenza, or flu, is a deadly respiratory illness because of influenza viruses. It spreads throughout the world in seasonal epidemics. An epidemic is a revolution of a disease within a population of people through a specific time. Each year in the United States, about 200,000 people are hospitalised, and 36,000 people die from the flu. Flu pandemics can destroy millions of people. An epidemic is a disease that spreads in human populations across a vast area or even worldwide. Three influenza pandemics happened in the 20th century and killed 10 millions of people, with each of these epidemics occurring produced by the presence of a new strain of the virus. Most massive influenza strains can be inactivated easily by disinfectants and cleansers

Here is List of Some Viral Diseases

Viral diseases are many general infections effected by viruses, a type of microorganism. There are many types of viruses that make a broad category of viral diseases.

  • Chickenpox
  • Human immunodeficiency virus (HIV/AIDS)
  • FHleur p(influenza)
  • Shingles
  • Mumps, measles, and rubella
  • gastroenteritis (stomach flu)
  • hepatitis
  • Human papillomavirus (HPV)
  • Infectious mononucleosis
  • Shingles
  • meningitis
  • pneumonia



Clinical characteristics of viruses may differ substantially between species within the similar family:VIRAL DISEASES
