Epidemiological Basis for Polio Eradication
Poliovirus causes acute, non-persistent infections
Virus is transmitted only by infectious humans or their waste
Virus survival in the environment is finiteHumans are the only reservoir Immunization with polio vaccine interrupts
virus transmission
• Measles affects humans only• No chronic carriers• Characteristic clinical illness• Highly effective measles vaccine• Herd immunity could prevent measles
Epidemiological Basis for Measles Eradication
