"A viral disease (or viral infection) occurs when an organism's body is invaded by pathogenic viruses, and infectious virus particles (virions) attach to and enter susceptible cells."
Caused by viruses, including common cold, influenza, and measles.
Basic biology of viruses: Understanding the structure and replication cycle of viruses is fundamental to grasping the mechanisms of viral infections.
Transmission mechanisms: How do viruses spread from person to person? Knowledge of transmission methods is key to preventing the spread of infection.
Immune response: How does the body respond to viral infections? Understanding the immune system's role is important for understanding the progression of infections and the potential for vaccines or treatments.
Epidemiology: Understanding how infections spread in populations is important for predicting and controlling outbreaks.
Viral entry and fusion: How viruses enter cells and initiate infection is a crucial step in disease progression.
Cell tropism: Different viruses have different preferences for cells they infect; understanding these tropisms can help predict disease outcomes and design targeted therapies.
Viral pathogenesis: Understanding the ways that viruses damage cells and tissues can help identify treatments or interventions to mitigate harm.
Diagnosis and detection: Knowing how to identify a viral infection and which tests to use is crucial for effective treatment and disease control.
Antiviral therapies: What options are available for treating viral infections? Understanding antiviral drugs and their limitations is important for treating patients.
Prophylaxis and prevention: What measures can be taken to prevent viral infections? Vaccines, hygiene practices, and public health interventions are all important strategies for disease prevention.
Influenza: A respiratory illness caused by the influenza virus.
Common cold: A viral infection of the upper respiratory tract.
Measles: A highly contagious viral infection that causes fever and rash.
Polio: A viral infection that can cause paralysis.
Chickenpox: A disease caused by the varicella-zoster virus that causes a rash and fever.
Herpes simplex: Causes sores or blisters on the lips and genitals.
Human immunodeficiency virus (HIV/AIDS): Damages the immune system over time.
Hepatitis: Inflammation of the liver, caused by a virus.
Ebola: A rare but severe hemorrhagic fever, caused by the Ebola virus.
Zika: A mosquito-borne virus that causes fever, rash, and joint pain.
