The registration rates from 2014-2018 were 93.70/100000 (1499/1599800), 85.08/100000 (1373/1613700), 82.85/100000 (1357/1637900), 73.12/100000 (1216/1663100) and 65.54/100000 (1110/1693600), which presented a tendency of decrease (χ ²=96.33, P=0.000). Patients were registered in each month, among which the numbers of patients registered in April and September were more, which was 631 (9.63%, 631/6555) and 605 (9.23%, 605/6555), respectively. All the streets in the district had registered patients, and the highest was Nanzhou Street with the average annual registration rate of 136.99/100000 (754/550411), and the lowest was Nanshitou Street with the average annual registration rate of 57.26/100000 (336/586848).
