Temporal and spatial differentiation of infectious diseases in China: Taking hepatitis and tuberculosis as an example

Viral hepatitis and tuberculosis affect social productivity seriously. Because they are two typical incidences of morbidity and mortality of infectious diseases, analysis of tuberculosis and hepatitis, and grasping their temporal and spatial differentiation, is an important task. The incidence and mortality of viral hepatitis and tuberculosis in China were revealed by ESDA. It was found that: (1) the morbidity and mortality of tuberculosis kept increasing before 2005, then began declining. The incidence of viral hepatitis volatility peaked in 1988, then declined slowly, with mortality declining; (2) morbidity of tuberculosis and viral hepatitis acted in a highly clustered manner. The incidence of tuberculosis in the west was the highest, decreasing gradually in the east; that in the north was higher than in the south with a lower gradient; the mortality in the middle was the lowest, with the east lower than the west. The incidence of viral hepatitis in the east was lower than in the west; the south was lower than the north, and mortality in total was low; (3) the incidence of tuberculosis morbidity was related closely to SO2 emission, and the incidence of hepatitis morbidity was related closely to GDP; the mortality rate was related closely to GDP
