Table 2 Changes in average yearly mortality due to five vector-borne diseases in 2020 compared to the previous 5 years (2015–2019) in China

Diseases	Average yearly mortality rates		Average yearly deaths (n)		Percentage change^a (95% CI)	P-value^b
Diseases	2020	2015–2019	2020	2015–2019	Percentage change^a (95% CI)	P-value^b
Overall	0.0014	0.0064	20	88	− 77.60 (− 100.64 to − 54.45)	< 0.001
EEB	0.0009	0.0053	12	73	− 83.67 (− 108.47 to − 59.05)	< 0.001

^aChanges = (x1 − ×2)/x2 × 100%, where x1 is the average yearly incidence in 2020, and x2 is the average yearly incidence in the previous 5 years (2015–2019)
^bThe P-value was computed using two proportional tests
