Objective:
To study the frequency and hazards of
cross infection of child rotavirus enteritis in the ward of a hospital.
Methods: Detecting the rate of RV-RNA from the excrement of the infants
suffering from diarrhea, the secretion of the patient��s throat, bed spreads
and doorknobs in the wards by using the method of PCK.
Results: Among the 60
children received in the hospital, 40.00% of whom have been tested suffered
from RV-RNA on the first day. The positive morbility of RV-RNA has got to
53.33% when rechecked 3 days later, P<0.05; While the positive reaction
rates of RV-RNA on the bed spreads used by Non-RV-RNA-infants and
Non-diarrhea ward have got to 38.89% and 5.00% respectively 3 days later,
P<0.05; The rates of positive reaction of RV-RNA on the doorknobs in the
diarrhea and non-diarrhea wards have increased to 82.35% and 23.08% respectively,
P<0.01; The rates of RV-RNA on the bed-spreads which have not been used
after disinfection for 1 day and 3 days are 11.11% and 10.00% respectively,
P>0.05.
Conclusion: The rate
of RV diarrhea accounts for 40.00��6.32% of the total diarrhea of infants. 3 days after received in
the hospital, the rate of patients suffered from RV-RNA has increased by
13.33%.
Causes of infection:
Contaminated bed spreads, doorknobs in the ward. Comparing the result of
AR% value, we will find that the rate of RV-RNA, on the basis of original
rate of epidemic, will decrease by 41.76% if we can receive the RV-RNA
positive patients in one ward. Likely, the rates of epidemic on the bed
spreads and doorknobs, on the basis of original rate of epidemic, will
decrease by 91.73% and 93.60% provided that we can separate the patients
according to RV-RNA positive reaction and RV-RNA negative reaction.
Key words: rotavirus enteritis, cross
infection, PCR.
