Analyzing Viral Disease Transmission
Chapter 14: Viruses and Monerans
Many human diseases are caused by viruses. The mode of transmission varies for each disease. The following table provides data which can be analyzed to compare body systems affected and modes of transmission.
Disease Tissue Effected Transmission Smallpox skin droplets in air; direct contact Chickenpox skin droplets in air; direct contact Rabies nerves animal bite Influenza repiratory tract droplets in air; direct contact Polio nerves poor sanitation Epstein Barr salivary glands direct contact HIV/AIDS immune system body fluid exchange Hepatitis B, Hepatitis C liver body fluid exchange Common cole respiratory tract droplets in air; direct contact
Analyze the Table
- Which diseases are transmitted through the air?
- Which diseases can be transmitted through body fluid exchange?
- Which disease currently poses the greatest threat to human populations?
- Why do you think it is important for infants and children to be vaccinated?
