Seva got started because we wanted to apply these lessons of surveillance and epidemiology to something which nobody else was looking at as a public health issue: blindness, which heretofore had been thought of only as a clinical disease.
Seva s-a constituit deoarece am vrut să aplicăm aceste lecţii ale supravegherii şi epidemiologiei asupra unui lucru pe care nimeni nu îl considera ca o problemă de sănătate publică: orbirea, care din acel moment am considerat-o o boală clinică.
