Descriptive epidemiological method was used to analyze the average annual registration rate, distribution of TB patient in different time and regions.Results A total of 6555 TB patients were registered from 2014 to 2018, the average annual registration rate was 79.86/100000 (6555/8208100), and that for household registered population and non-household registered population were 68.77/100000 (3529/5131400) and 98.35/100000 (3026/3076700) with 3529 and 3026 TB patients registered respectively. 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). There were 4545 male patients and 2010 female patients in the district, with a male-female ratio of 2.3∶1. The majority of TB patients were aged 25-34 years, accounting for 21.88% (1434/6555). However, the registration rate of 55-64 years age group was the highest for household registered population, accounting for 21.82% (770/3529). The highest occupational distribution was among the housework and unemployed patients, accounting for 45.98% (3014/6555).Conclusion From 2014 to 2018, the epidemic of TB in Haizhu District of Guangzhou shows a declining trend year by year, and the epidemic control has achieved certain results.
