Pseudotumoral acute cerebellitis associated with mumps infection in a child

Pseudotumoral cerebellitis in childhood is an uncommon presentation of cerebellitis mimicking a brain tumor. It often follows an inflammatory or infectious event, particularly due to varicella virus. Patients could have a wide clinical spectrum on presentation. Some patients may be asymptomatic or present at most with mild cerebellar signs, whereas others may suffer severe forms with brainstem involvement and severe intracranial hypertension mimicking tumor warranting surgical intervention. Imaging techniques especially multimodal magnetic resonance imaging represent an interesting tool to differentiate between posterior fossa tumors and acute cerebellitis. We describe a case of pseudotumoral cerebellitis in a 6-year-old girl consequent to mumps infection and review the literature on this rare association.

Complete Nucleotide Sequence of a Mumps Virus SP Strain Isolated in China

The complete nucleotide sequence of the mumps virus SP, which was isolated in China, was determined. As with other mumps viruses, its genome was 15 384 nucleotides (nts) in length and encoded seven proteins. The full-length nucleotide sequence of the SP isolate differed from other strains by 4% –6.8% at the nucleotide sequence level. Due to variations of amino acids over the full genome (including the HN and N genes), this isolate exhibited significant variations in the antigenic sites. This report is the first to describe the full-length genome of a genotype F strain and provide an overview of the diversity of genetic characteristics of a circulating mumps virus.

Epidemic Outbreaks in Plovdiv Region (Bulgaria) of Vaccine-Preventable Diseases: Measles, Mumps, Hepatitis A

Aim: To analyze the reasons for epidemic outbreaks of measles, mumps and viral hepatitis A and to propose measures to prevent them in future. Materials and methods: Тhe incidence of measles, mumps and hepatitis A in Plovdiv region was studied for the period 2006-2010. An analysis of the age structure of the patients was made, while taking into account the time for routine immunization performed against measles and mumps (first and second dose). Results: In 2006-2009 single cases of measles were found occasionally, but in 2010 they were 2787 (incidence 395/100,000). Most of them (51%) were for ages 13 months-12years, 27%-0-13 months and 11%-13 to 18 years. The incidence of mumps for 2006-2010 varied widely, and has increased significantly in 2007 (130/100,000) and 2008 (169/100,000). The majority of patients (over 34%) during the epidemics were aged 13 months-12years, and over 26% of them-13-19 years. For the period 2006-2010 the incidence of hepatitis A ranged from 2.98/100, 000 (2009) to 426/100,000 (2006). Over 50% of the cases involved children aged up to 9 years. For the three diseases over 80% of patients were individuals of Roma origin. Conclusions: 1. Epidemic spread of measles in 2010 was mainly due to shortcomings in the routine immunization carried as a prevention of the disease. 2. There are two reasons for the outbreak of mumps: А) Failure to administer the second vaccine dose at 12 years in Bulgaria until 2001. B) Shortcomings in routinely performed immunization. 3. The extremely high incidence of hepatitis A in 2006 (and in the rest of the years) is due to the lack of routine immunization. 4. Essential for the outbreaks in all three diseases are the poor hygienic living conditions, the low social status and the lack of health promotion of the population at risk 5. To prevent future outbreaks of the diseases hereby in question, we suggest it is appropriate: А) To introduce compulsory immunization against hepatitis A;B) To carry out periodic catch-up vaccination campaigns against measles and mumps.

Epidemiological Characteristics of Measles-Mumps-Rubella in China’s Mainland during 2014-2021

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。

Epidemiologic features of mumps in China Taiwan from 2006 to 2011:a new challenge for public health policy

Background:The adoption of a second dose of the measles-mumps-rubella(MMR)vaccine among Taiwan residents school children began in 2001.However,during that time,mumps cases continued to occur.The purpose of the present study was to assess the epidemiology and vaccination policy for mumps in Taiwan.Methods:We examined the data on mumps cases collected by the Taiwan Centers for Disease Control(Taiwan CDC)between 2006 and 2011.Results:During the 6-year study period,a total of 6612 cases of mumps were reported to the Taiwan CDC.Of the patients with known vaccination status,62%received one dose of the MMR vaccine or no vaccine.The incidence of mumps ranged from 4.18 to 5.28 per 100000 population and peaked in 2007.Males had a higher incidence of mumps than females(5.9 vs.3.7 per 100000 population;P=0.024).Children between 5 and 6 years of age had the highest incidence of mumps,and those 20 years and older had the lowest incidence.Compared to those who received two doses of the MMR vaccine,patients who were not vaccinated or received a single dose of the vaccine had a higher risk of suffering from complications and/or hospitalization.Conclusions:In Taiwan,more than 60%of mumps cases received either no dose or one dose of the MMR vaccine.Monitoring mumps through biological testing and instituting a second dose of the MMR vaccine for children is needed for the elimination of mumps in Taiwan.

Evaluation of live attenuated S79 mumps vaccine effectiveness in mumps outbreaks： a matched case-control study

Background Mumps virus infection is a potentially serious viral infection of childhood and early adulthood. In China, live attenuated S79 mumps vaccine has been licensed for pediatric use since 1990. The objective of this study was to determine the effectiveness of live attenuated S79 mumps vaccine against clinical mumps in outbreaks. Methods Cases were selected from mumps outbreaks in schools in Guangzhou between 2004 and 2005. Each case was matched by gender, age and classroom. Vaccination information was obtained from Children＇s EPI Administrative Computerized System. Vaccine effectiveness （VE） was calculated for 1 or 2 doses of S79 vaccine with 95% confidence intervals （CI）. Results One hundred and ninety-four cases and 194 controls were enrolled into the study. VE of the S79 mumps vaccine for 1 dose versus 0 confer protection 80.4% （95% Cl, 60.0%-90.4%） and VEs against mumps in outbreaks for 1 dose of mumps vaccine are similar among those children aged 4-9 years and aged over 10 years old. Conclusion The live attenuated S79 mumps vaccine can be effective in preventing clinical mumps outbreaks.

A mumps model with seasonality in China

Background:Mumps,an infectious viral disease,classically manifested by inflammation of salivary glands and is best known as a common childhood viral disease with no specific treatment.Although it can be protected by vaccine,there are more than 100,000 reported mumps cases according to the Chinese Center for Disease Control and Prevention.However,the factors and mechanisms behind the persistence and prevalence of mumps have not been well understood.Methods:A mumps model with seasonal fluctuation is formulated and investigated.We evaluate the basic reproduction numberℛ0 and analyze the dynamical behavior of the model.We also use the model to simulate the monthly data of mumps cases and carry out some sensitivity analysis ofℛ0 in terms of various model parameters.Results:It is shown that there exists only disease-free solution which is globally asymptotically stable ifℛ0<1,and there exists a positive periodic solution ifℛ0>1.ℛ0 is a threshold parameter,and its magnitude determines the extinction or persistence of the disease.Conclusion:Our analysis shows that vaccination rate and invalid vaccination rate play important roles in the spread of mumps.Hence,Our study suggests to increase the vaccine coverage and make two doses of MMR(Measles,mumps and rubella vaccine)vaccine freely available in China.

Global Stability of a Mumps Transmission Model with Quarantine Measure

In this paper,a model of mumps transmission with quarantine measure is proposed and then the control reproduction number Rc of the model is obtained.This model admits a unique endemic equilibrium P*if and only if Rc>1,while the disease-free equilibrium P0 always exists.By using the technique of constructing Lyapunov functions and the generalized Lyapunov-LaSalle theorem,we first show that the equilibrium P0 is globally asymptotically stable(GAS)if Rc≤1;second,we prove that the equilibrium P*is GAS if Rc>1.Our results reveal that mumps can be eliminated from the community for Rc≤1 and it will be persistent for Rc>1,and quarantine measure can also effectively control the mumps transmission.

Establishment of an efficient reverse genetic system of Mumps virus S79 from cloned DNA

Background Mumps is a common type of respiratory infectious disease caused by mumps virus(MuV),and can be effectively prevented by vaccination.In this study,a reverse genetic system of MuV that can facilitate the rational design of safer,more efficient mumps vaccine candidates is established.Methods MuV-S79 cDNA clone was assembled into a full-length plasmid by means of the GeneArtTM High-Order Genetic Assembly System,and was rescued via reverse genetic technology.RT-PCR,sequencing,and immunofluorescence assays were used for rMuV-S79 authentication.Viral replication kinetics and in vivo experimental models were used to evaluate the replication,safety,and immunogenicity of rMuV-S79.Results A full-length cDNA clone of MuV-S79 in the assembly process was generated by a novel plasmid assemble strategy,and a robust reverse genetic system of MuV-S79 was successfully established.The established rMuV-S79 strain could reach a high virus titer in vitro.The average viral titer of rMuV-S79 in the lung tissues was 2.68±0.14 log10PFU/g lung tissue,and rMuV-S79 group did not induce inflammation in the lung tissues in cotton rats.Neutralizing antibody titers induced by rMuV-S79 were high,long-lasting and could provide complete protection against MuV wild strain challenge.Conclusion We have established a robust reverse genetic system of MuV-S79 which can facilitate the optimization of mumps vaccines.rMuV-S79 rescued could reach a high virus titer and the safety was proven in vivo.It could also provide complete protection against MuV wild strain challenge.

Correlation between mumps and meteorological factors in Xiamen City,China:A modelling study

Objective:Mumps is a seasonal infectious disease,always occurring in winter and spring.In this study,we aim to analyze its epidemiological characteristics,transmissibility,and its correlation with meteorological variables.Method:A seasonal Susceptiblee Exposede Infectious/Asymptomatice Recovered model and a next-generation matrix method were applied to estimate the time-dependent reproduction number(Rt).Results:The seasonal double peak of annual incidence was mainly in May to July and November to December.There was high transmission at the median of Rt¼1.091(ranged:0 to 4.393).Rt was seasonally distributed mainly from February to April and from September to November.Correlations were found between temperature(Pearson correlation coefficient[r]ranged:from 0.101 to 0.115),average relative humidity(r¼0.070),average local pressure(r¼-0.066),and the number of new cases.In addition,average local pressure(r¼0.188),average wind speed(r¼0.111),air temperature(r ranged:-0.128 to-0.150),average relative humidity(r¼-0.203)and sunshine duration(r¼-0.075)were all correlated with Rt.Conclusion:A relatively high level of transmissibility has been found in Xiamen City,leading to a continuous epidemic of mumps.Meteorological factors,especially air temperature and relative humidity,may be more closely associated with mumps than other factors.

Development of Improved Mumps Vaccine Candidates by Mutating Viral mRNA Cap Methyltransferase Sites in the Large Polymerase Protein

Although a live attenuated vaccine is available for controlling mumps virus(MuV), mumps still outbreaks frequently worldwide. The attenuated MuV vaccine strain S79 is widely used in mumps vaccination in China, but still with many shortcomings, among which the most prominent are the side effects and decreased immunity. Therefore, there is a need to further improve the safety and efficacy of the current MuV vaccine. In the present study, we further attenuated MuV S79 vaccine strain by inhibiting viral mRNA methyltransferase(MTase). We generated a panel of eight recombinant MuVs(rMuVs) carrying mutations in the MTase catalytic site or S-adenosylmethionine(SAM) binding site in the large(L) polymerase protein. These rMuVs are genetically stable and seven rMuVs are more attenuated in replication in cell culture and five r MuVs are more attenuated in replication in lungs of cotton rats compared with the parental vaccine strain S79. Importantly, cotton rats vaccinated with these seven rMuV mutants produced high levels of serum neutralizing antibodies and were completely protected against challenge with a wild-type MuV strain(genotype F). Therefore, our results demonstrate that alteration in the MTase catalytic site or SAM binding site in MuV L protein improves the safety or the immunogenicity of the MuV vaccine and thus mRNA cap MTase may be an effective target for the development of new vaccine candidates for MuV.

This paper reports two seronegative cases of parotid swelling following MMR vaccination,which contains Hoshino strain of mumps virus.This study showed a high,(5%) potential reactogenicity induced by Hoshino strain of current MMR vaccine administered in Iranian EPI.The rate of complication of parotid swelling following national immunization against mumps is more than natural infection.Based on the results of this report, there is the first report of occurrence of parotid swelling 31 days following MMR vaccination.This reaction or complication may not be dependent on the vaccine dose,because one of cases presented parotid swelling following taking one fifth of conventional dose of vaccine.It must be considered this strain may be with high rate of complication and be the subject of change of mumps strain of this vaccine in national immunization program of Iran.

Safety and Antibody Responses to Aerosolized MMR II Vaccine in Adults: An Exploratory Study

Background: There have been no reported studies involving aerosol immunization with 2 of the 3 components of MMR II vaccine—Attenuvax measles vaccine and Jeryl-Lyn mumps vaccine. Objective: To evaluate the safety and antibody responses to aerosolized Attenuvax measles strain, Jeryl Lynn mumps strain and RA 27/3 rubella component of an MMR vaccine in adults, before assessing the booster administration of this vaccine in children. Methods: A pilot study to evaluate safety and antibody responses of MMR II (Merch Sharp & Dhome Corp., Whitehouse Station, NJ 08889, USA) components administered by aerosol was carried out in 27 healthy adults of 21 to 38 years of age. All participants were followed-up during 28 days following immunization for detection of clinical adverse events. Immune response was evaluated by plaque reduction neutralization test for measles, and commercial ELISA kits for rubella and mumps. Results: Only mild clinical adverse events were noted. Despite high levels of baseline seropositivity to all vaccine components, seroresponses to measles, rubella and mumps occurred in 44%, 15% and 41%, respectively. Conclusions: These outcomes compare favorably with earlier studies of other MMR vaccines given by aerosol. Further evaluations on safety and booster immune response should be performed in children.
