Further analysis found that the notification rates were significantly higher in specific sex and age groups than those of the rest of the city. The city\u2019s outbreak records showed three actual outbreaks (one in Atsubetsu ward in 2010 and two in Higashi in 2014) corresponding to two events found in our analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSION<\/jats:title>\n                    <jats:p>Our study shows that retrospectively reviewing TB surveillance data could detect possible outbreaks.
