Epidemiological characteristics of rubella in Hefei from 2014 to 2023
Objective To understand the epidemiological characteristics of rubella in Hefei from 2014 to 2023, and to provide a theoretical basis for its prevention and control. Methods The reported cases of rubella in Hefei from 2014 to 2023 were collected from the Chinese Information System for Disease Control and Prevention, and the incidence characteristics of rubella in Hefei were descriptively analyzed by Excel 2007 software. Results From 2014 to 2023, a total of 424 rubella cases were reported in Hefei, with an average annual reporting rate of 0.53/100 000. In 2015 and 2019, there were two peaks of reported cases of rubella, with incidence rates of 1.25/100 000 and 2.72/100 000, respectively, and no deaths were observed. However, after the second peak, the incidence rate rapidly decreased to a low level in 2020 (0.10/100 000) and tended to stabilize. Cases were reported in all counties (cities and districts), the average annual incidence rates of Shushan District (0.99/100 000) and Feixi County (2.00/100 000) were higher than the city’s average level, and the reported incidence rate of Chaohu (0.06/100 000) was the lowest. The onset time was mainly from March to June (55.42%, 235/424), and the peak incidence was from April to May (36.79%, 156/424) of all cases. The reported incidence rates of rubella in males and females were 0.63/100 000 and 0.39/100 000, respectively. The age of onset was mainly 15-29 years old, accounting for 75.47% (320/424) of all cases. Workers (182 cases,42.92%) were the main patients, followed by students (80 cases, 18.87%). Among the reported rubella cases, 3.30%, 5.66%, 5.90% and 85.38% cases were immunized with 0 dose, 1 dose, 2 doses, and unknown rubella-containing vaccines. Conclusion Except for 2015 and 2019, the incidence of rubella in Hefei showed a downward trend. However, the age of onset shifted from younger to older age. Measures should be taken to guarantee complete vaccination rates in age-eligible children, provide timely catch-up vaccinations for missed cases, and enhance rubella monitoring systems.

Rubella-containing vaccine (RCV) became available in China in 1993 and was introduced nationwide into the Expanded Immunization Program (EPI) in 2008. We evaluated implementation and impact of RCV from 2 years prior to nationwide introduction through the 10 years after nationwide introduction.We analyzed RCV lot-release (doses distributed) data, 1- and 2-dose RCV coverage, and rubella data from China's nationwide disease surveillance system to describe the current status and changes in rubella epidemiology between 2005 and 2017.While the vaccine was included into the routine immunization program in 2008, its full implementation required 4 years due to sporadic vaccine supply constraints. RCV1 and RCV2 coverage increased from 51.5% and 39.0% in 2008 to >95% during 2012 through 2016. From 2005 to 2017, the annual incidences (per million) of rubella ranged from 91.09 in 2008 down to 1.16 in 2017; reductions occurred in all age groups. The proportion of cases among individuals ≥20 years old increased from 0.97% in 2005 to 31.2% in 2017. In the better-developed eastern China, most cases were among adults; in central and western China, most cases were among children or adolescents.The marked decrease rubella was a result of inclusion of RCVs into EPI targeting children less than 2 years of age and achieving high level of 2-dose coverage. Rubella was reduced in absolute terms, and its epidemiology was changed to older cases with substantial inter-province variation. Ensuring full vaccination of school children and identifying strategies to reach adults with measles and rubella combined vaccines will be important to hasten elimination of rubella and prevent CRS outbreaks.Copyright © 2018 Elsevier Ltd.

The incidence of rubella cases in China from 1991 to 2007 was reviewed, and the nucleotide sequences from 123 rubella viruses collected during 1999 to 2007 and 4 viral sequences previously reported from 1979 to 1984 were phylogenetically analyzed. Rubella vaccination was not included in national immunization programs in China before 2007. Changes in endemic viruses were compared with incidences of rubella epidemics. The results showed that rubella epidemics occur approximately every 6 to 8 years (1993/1994, 2001, and 2007), and a shift of disease burden to susceptible young adults was observed. The Chinese rubella virus sequences were categorized into 5 of the 13 rubella virus genotypes, 1a, 1E, 1F, 2A, and 2B; cocirculations of these different genotypes were found in China. In Anhui province, a shift in the predominant genotype from 1F and 2B to 1E coincided with the 2001 rubella epidemic. This shift may have occurred throughout China during 2001 to 2007. This study investigated the genotype distribution of rubella viruses in China over a 28-year period to establish an important genetic baseline in China during its prevaccination era.
