Severe HFRS showed different clinical and laboratory
characteristics
Statistical analysis showed that HFRS patients with a history of rat
contact history (χ 2=5.712,P = 0.024
<
0.05),
muscle and joint pain (χ 2= 14.438,P =
0.000 < 0.01), weight loss
(χ 2=14.438,P = 0.000< 0.01),
pharyngeal (χ 2= 17.679,P = 0.000
< 0.01) conjunctival(χ 2=
14.438,P = 0.000< 0.01) hyperemia, abnormal white
blood cell count (χ 2= 9.900,P = 0.003
< 0.01), urine protein (χ 2=
9.900,P =0.003 < 0.01) and antibody IGM
(χ 2= 11.917,P = 0.001<
0.01)
positive cases had a higher severe rate. The differences between the two
groups were statistically significant (P < 0.05).
