Objective:To analyze the epidemiological characteristics of an aggregational gastroenteritis and determine the genotypes of sapovirus， and to provide scientific basis for formulating effective control strategies. Methods:Unified case definition， active case search and descriptive epidemiology were used to analyze the epidemic. Feces or anal swabs of untreated students， teachers， canteen staff as well as canteen environment samples were collected. Norovirus and sapovirus nucleic acid tests were conducted by real-time fluorescent RT-PCR， and sapovirus nucleic acid was amplified by conventional RT-PCR. The gene region of capsid protein was analyzed by MEGA7.0 software and phylogenetic tree was constructed. Results:A total of 12 cases were reported in the epidemic， and the incidence rate was 44.44%. All reported cases， with vomiting symptoms， were found in the same class. The epidemic showed a point-based outbreak. The first case became the source of infection in class， and the epidemic lasted for 8 days. Real-time fluorescent RT-PCR assay confirmed that five children's feces were positive for sapovirus nucleic acid， and the first-episode children's feces were positive for sapovirus and GII norovirus nucleic acid. Sequence alignment result showed that the sapovirus strains belonged to GI.1 type with homologous genes. Conclusion:Based on the clinical manifestations， field epidemiological investigation and laboratory test results， we confirm that the first case of the epidemic in class is caused by GI.1 sapovirus infection. The epidemic is effectively controlled by comprehensive measures such as case isolation and disinfection.

Objective To investigate measles antibody levels in healthy people in Jinshan District and their willingness to inoculate measles containing vaccines, and to explore the feasibility of supplementary immunization with adult measles vaccine. Methods People from 4 randomly selected community health service centers were enrolled and divided into groups of 15-19, 20-29, 30-39, and 40 years old and above. Serum was collected for measles antibody level detection and analysis according to the city and foreign household registration. In addition, a questionnaire survey on measles knowledge and vaccination willingness was conducted. Results Of the 234 participants for serum testing, the overall positive rate of measles antibodies (IgG) was 85.47%, and the protection rate was 35.47%. The difference in the positive rate of antibodies in different age groups was statistically significant (χ2=9.78, P=0.02), and the difference in the protection rate was also statistically significant (χ2=14.97, P<0.0012). The positive rate and protection rate were lowest in the group of 20-29 years old, which were 74.19% and 24.19%, respectively. A total of 490 questionnaires were sent out, and 477 questionnaires were effectively returned. Among the 5 questions about measles knowledge, the lowest correct rate was for the transmission route of measles, which was only 48.64%. The willingness to measles vaccination was 85.12%. Multivariate analysis showed that the willingness to vaccination was related to the level of awareness and health education. Conclusion The level of protective antibodies against measles was low in adults in Jinshan District. Health education on measles was insufficient. It is necessary to conduct measles health publicity in institutions with more concentrated personnel. In addition, appropriate measles serological monitoring and supplementary immunization should be carried out for key populations to increase the level of measles antibodies.

ObjectiveTo determine the level of anti-measles antibody and its fluctuation trend in children under 8 months old， which may provide evidence for enhancing the measles immunization strategy. MethodsA cross-sectional study was conducted to collect the serum of the children aged 1‒8 months in a children’s medical center in Shanghai. Serum concentration of anti-measles IgG antibody was determined by enzyme-linked immunosorbent assay （ELISA）， and dynamics of IgG antibody level was compared. ResultsA total of 837 children aged 1‒8 months were tested for anti-measles antibody， and there was no statistical difference in the antibody level between boys and girls （P>0.05）. In the age of 1 month children， the average geometric antibody concentration （GMC） was 529.66 IU‧L-1， and the antibody positive rate and protection rate were 86.07% and 29.51% respectively. After the age of 3 months， the antibody level dropped sharply in the age of 8 months children， the GMC decreased to 44.46 IU‧L-1. The positive rate was 12.00%， and the protection rate was 1.00%. The mathematical model of GMC reduction trend in children aged 1‒8 months was Ŷ=-0.144 8X+2.640（R2=0.911 3， P<0.001）. ConclusionThe low level of mother-transmitted protective antibody and its downward trend with age are the important factors leading to the incidence of measles in children aged1‒8 months. It is suggested that intensive immunization should be carried out for women of childbearing age to improve the level of mother-transmitted antibodies in her baby.
