Operation of the evacuation site surveillance for the Great East Japan Earthquake in 2011

In 2011, March 11th, the big earthquake attacked eastern Japan, and forced a lot of people to live in evacuation sites. Since those evaluation sites have high density of population and sanitary condition was poor in these sites, outbreaks of influenza, noro virus or other infectious diseases were concerned.

Objective

For an early detection and control of an infectious disease outbreak, we developed and have been operating syndromic surveillance for evacuation sites, "evacuation site surveillance."
