Polio Endgame: Innovations in Surveillance


Background: Provides a definition of eradication and of the disease: that it affects mostly children, results in paralysis in some cases and is preventable through vaccination. 

The disease is nearly eradicated, but remains in three countries, which reported 22 cases in 2017. Eradication practices continue with 400 million vaccinations annually. 

Surveillance: Virus detection activities currently take place in 70 countries to both detect new cases and gain evidence for certification of eradication.  

Innovations in environmental surveillance are detailed.

His research is focused on generating data regarding the best use of polio vaccines to make them affordable and accessible to vulnerable and underserved populations. He is also involved in enhancing and expanding polio environmental surveillance globally with newer tools and diagnostics. His work on immunogenicity of new polio vaccines, endgame vaccination schedules and surveillance methodologies have been impactful in global policy formulation and have been published in leading peer-reviewed Journals. Ananda is also associated with advanced degree programs in public health and vaccinology in several globally renowned teaching venues as a guest faculty.
