Objective: To
investigate the virus distribution and the clinical features of child
respiratory tract infection with enteric cytopathogenic human orphan(EHCO)

Results: EHCO virus
antigen was found in 20 cases and the positive rate was 20.6%, of which 12
cases were pneumonia, 2 acute brochitis, and 6 upper respiratory tract
infection, while it was found only in one case in control group. There was
significant difference in the positive rate of the antigen between the
patients and the control group (P<0.05).
All the patients manifested fever, diarrhea and congestion of throat.
Besides, skin rash appeared in 13 cases, hot convulsion in 4 cases,
temporary myodynamia attenuation of unilateral leg in 2 cases, and trasient
increase of some enzymes in 4 cases.
