OBJECTIVE: To analyze the epidemiological characteristics of measles, mumps, and rubella (MMR) between 2014 and 2021 and identify potential strategies and measures for the prevention and control of MMR in China. METHODS: Data on MMR was obtained from China's National Notifiable Disease Reporting System for the period from 2014 to 2021. Spatiotemporal distributions were analyzed using SaTScan; temporal trends were analyzed using JoinPoint; and clusters were visualized using ArcGIS. RESULTS: A total of 1,808,067 cases of MMR were reported from 2014 to 2021 in China's mainland, most of which were children and students under the age of 20. The incidence of measles declined during 2014-2021, whereas that of mumps and rubella peaked in 2019. MMR-reported cases generally peaked from March to July; however, high numbers of mumps cases were reported from September to November in 2020-2021. Measles and rubella clusters predominantly occurred in Western China, whereas clusters of mumps were generally found in the southern region. CONCLUSION The relatively heterogeneous epidemiological characteristics of MMR have highlighted the weaknesses and gaps in surveillance and timely control of MMR transmission in China's mainland. Real-time and intelligent monitoring data should be collected for evidence-based early interventions.

Objective: To determine IgG antibody levels of measles, rubella, mumps in healthy population in Shanghai from 2010 to 2020 and analyze the trend of antibody changes in different age groups. Methods: 10 828 healthy people without measles, rubella and mumps in Shanghai were included in the study from 2010 to 2020. Serum samples were collected from 12 age groups, and the serum IgG antibody of measles, rubella and mumps were detected by ELISA. The difference of antibody positive rates and antibody levels were analyzed. Results: The median age M (Q₁, Q₃) of 10 828 objects were 8 years old (9 months old, 20 years old). Males accounted for 48.34% (5 234/10 828) and females accounted for 50.92% (5 514/10 828). Unknown gender information accounted for 0.74% (80/10 828), and 27.03% (2 927/10 828) of participants had unknown MMR immunization history. The total positive rates of measles, rubella and mumps IgG antibody were 76.78%, 64.46% and 64.29% and their GMCs were 541.45 mIU/ml, 31.76 IU/ml and 133.73 U/ml respectively. There were significant differences in serum IgG antibody GMC of measles, rubella and mumps in each year (F_measles=180.74, P<0.001; F_rubella=189.95, P<0.001; F_mumps=122.40, P<0.001). The positive rate of measles antibody was higher than that of rubella and mumps, and the difference was statistically significant (χ²=518.09, P<0.001). Conclusion: The level of measles IgG antibody in healthy people in Shanghai is higher, while the level of rubella and mumps IgG antibody is slightly lower.

An increase in the number of patients with infectious diseases in Korea, can be attributed to various factors, such as the prevalence of new infectious diseases of the 21st century, the re-emergence of past infectious diseases, an increase in the number of elderly individuals, patients with chronic diseases, immune deficiency, and globalization. In this context, vaccination becomes vital for the adult population. Although, the guidelines for adult immunization are currently being updated, the rate of adult vaccination remains lower than that of infant vaccination. At present, the major challenges for increasing the rate of adult immunization include negative views on the need for some immunizations and a lack of understanding of group immunity among the youth. Consequently, a successful immunization program will be required to direct efforts towards educating patients and spreading awareness. Based on the current guidelines and practical applications, varicella zoster; Japanese encephalitis; tetanus, diphtheria, and pertussis; pneumococcus; measles, mumps, and rubella; and hepatitis A vaccines could effectively be considered for adult vaccination.

Mumps is contagious disease and maintaining immunity to mumps in healthcare worker (HCW) is important for preventing transmission in the hospital. We evaluated the seroprevalence of mumps in HCWs in a tertiary care hospital in Republic of Korea. A total of 6,055 HCWs born between 1950 and 1995 underwent antibody testing. The overall seropositivity rate of mumps was 87% (95% confidence interval, 86%–87%). Our data indicates that, in Korean HCWs, testing for mumps antibody followed by mumps vaccination is more appropriate than routine mumps vaccination without testing for mumps antibody.]]>

BACKGROUND: Warts, caused by the human papilloma virus (HPV), are mucocutaneous proliferations controlled by cell-mediated immunity. Intralesional immunotherapy with measles, mumps, and rubella (MMR) vaccine, is postulated to induce a higher immune response for clearance of lesions.
OBJECTIVE: To assess the efficacy, safety and effect on recurrence of intralesional MMR vaccine for the treatment of warts.
METHODS: We searched online databases for randomized controlled trials on intralesional MMR vaccine for warts. Effects measured were the complete clearance of target and distant warts, adverse events noted and recurrence after treatment duration.
RESULTS: Four RCTs comparing intralesional MMR vaccine and placebo were assessed. Meta-analysis showed a risk ratio of 0.24 [95% CI: 0.18, 0.34] favoring intralesional MMR vaccine and a highly significant difference in completely clearing target warts (P-value <0.00001) versus placebo. Three of the 4 trials assessed response of distant warts showing a risk ratio of 0.28 [95% CI: 0.08, 0.96] and a significant difference (P=0.04) versus placebo. Pain and flu-like symptoms were the most common side effects with no recurrence seen after 3-6 months.
CONCLUSIONS: Intralesional MMR vaccine significantly reduces and clears target and distant warts as compared to placebo. It is a generally safe intervention with lasting effect assessed up to 6 months follow-up.

OBJECTIVE: To investigate the epidemiological characteristics of mumps in mainland China from 2004 to 2018, and to provide data for the key population for prevention and control of mumps. METHODS: The epidemiological characteristics of mumps were analyzed with reference to the data of the cases of mumps reported in the National Scientific Data Sharing Platform for Population and Health and Disease Prevention and Control Bureau of National Health Commission of the People's Republic of China. Descriptive epidemiology was used to analyze the epidemiological characteristics of mumps. RESULTS: A total of 4 272 368 cases of mumps were reported in China during 2004-2018, with an average annual reported incidence rate of 21.44/100 000. A single dose of mumps-containing vaccine was added to the national Expanded Program of Immunization in 2008, but the annual incidence rate ranged from 12.84/100 000 to 35.59/100 000. The second dose of measles, mumps and rubella combined attenuated live vaccine was included in the routine immunization in Beijing, Tianjin and Shanghai, and then the average incidence rate of mumps reported in these three regions dropped to about 10/100 000. From 2004 to 2016, the population aged 3-14 years accounted for 81.16% of all patients with mumps. The children aged 6 years had the highest incidence rate of mumps during 2004-2013. CONCLUSIONS A single dose of mumps-containing vaccine has no obvious effect on the incidence rate of mumps. Children aged 6 years have the highest incidence rate of mumps. A booster dose of mumps-containing vaccine should be given to preschool children.

In countries and regions with high vaccination coverage, several vaccine-preventable diseases have been resurged in recent years, such as measles, varicella, pertussis and mumps. Some studies have found that the clinical manifestation and epidemiological characteristics of these diseases were different from those in pre-vaccine era. This article reviewed the clinical and epidemiological features of vaccine-preventable diseases before and after wide immunization implementation, focusing on the situation in China, in order to attract the attention of clinicians, raise awareness, strengthen prevention and control, and promote in-depth research for these diseases.

OBJECTIVES: Although the nationwide inoculation rate of varicella vaccine was approximately 95% in Korean children recently, the number of notified varicella cases is unexpectedly continuously increasing till now. To suggest some hypotheses regarding this discrepancy, an age-period-cohort (APC) analysis as a descriptive epidemiology study was conducted for children residing in Jeju-do, Korea. METHODS: The raw data were obtained from the nationwide database for insurance claim of healthcare fee provided by the National Health Insurance Service, Korea. The selection criteria were children aged 2–13 years who visited any healthcare center due to varicella from 2005 to 2016 while residing in Jeju-do. After calculating the birth cohort-specific crude incidence rates by age and year, the intrinsic estimator method was used to perform the APC analysis. RESULTS: As the annual crude incidence rates decreased with increasing age between 2005 and 2016, the age and period effects also decreased. The intrinsic estimator coefficients suggesting the cohort effect shifted from positive to negative in 2011, the starting year of free varicella vaccine program in Jeju-do. CONCLUSIONS: The results suggested that inoculated varicella vaccines have preventive effects. However, further studies to evaluate waning immunity would be needed.
