  2. German Measles Virus Icosahedral shape Contains RNA

  3. German Measles Symptoms Rubella comes from the Latin words for “little red” Creates dense groups of small skin rash Produces swollen lymph nodes, runny nose, and fever

  4. German Measles Transmission Spread through respiratory droplets from coughing and sneezing Also spread through body secretions and excretions

  5. Rubella - CRS

  6. Mumps (Parotitis)

  7. Mumps Virus Helical shape RNA virus

  8. Mumps Symptoms Infects salivary glands, especially the parotid gland Primary symptom is swollen checks Can also cause fever, headache, and malaise Testicular inflammation is common, ovarian inflammation can happen but is rare

  9. Mumps

  10. Mumps Transmission Spread through airborne transmission of respiratory droplets by sneezing and coughing Also spread from direct contact with saliva

  11. Smallpox

  12. Smallpox Virus Variola virus Contains DNA

  13. Smallpox Symptoms Pox comes from the Latin word for “spotted” Extensive rash High fever, malaise, and body-aches Elevated, fluid-filled, cutaneous vesicles
