Analysis of co-infection of other viruses in some confirmed measles cases in Jilin Province from 2013 to 2022 / 中国生物制品学杂志

ABSTRACT

@#Objective To analyze rash and fever illness(RFI) and other respiratory virus co-infection in some confirmed measles cases in Jilin Province from 2013 to 2022,and to provide scientific basis for measles co-infection and multi-pathogen diagnosis.Methods The throat swab specimens of 106 measles confirmed cases in Jilin Province from 2013 to 2022 were collected,of which nine kinds of RFI associated virus and respiratory virus with similar clinical symptoms were detected by fluorescence quantitative PCR,including varicella-zoster virus(VZV),Dengue virus(DENY),human parvovirus B19(HPV-B19),Epstein-Barr virus(EBV),human herpesvirus6(HHV6),human rhinovirus(HRV),respiratory syncytial virus(RSV),human adenovirus(HAdV) and human cytomegalovirus(HCMV),and statistical analysis was conducted by using SPSS 23.0 software.Results VZV and DENV were not detected in the 106 collected specimens,and the other 7viruses were detected.30.18% of the measles cases were co-infected with other viruses,of which only HCMV co-infection cases showed significant difference in the age groups(≤24 months old,24 months old to 15 years old,> 15 years old)(χ~2=9.941,P <0.05);there was no significant difference between the genders in cases co-infected with other viruses(χ~2=0.200—2.778,each P> 0.05).Conclusion Some confirmed cases of measles might be co-infected with one or more other viruses in Jilin Province from 2013 to 2022,and it is recommended to strengthen targeted surveillance and differential diagnosis,especially for infants and young children,women of childbearing age and pregnant women.
