Abstract
MuV caused three epidemic waves in Spain since genotype G emerged in 2005, despite high vaccination coverage. SH gene sequencing according to WHO protocols allowed the identification of seven relevant variants and 88 haplotypes. While the originally imported MuVi/Sheffield.GBR/1.05/-variant prevailed during the first two waves, it was subsequently replaced by other variants originated by either local evolution or importation, according to the additional analysis of hypervariable NCRs. The time of emergence of the MRCA of each MuV variant clade was concordant with the data of the earliest sequence. The analysis of Shannon entropy showed an accumulation of variability on six particular positions as the cause of the increase on the number of circulating SH variants. Consequently, SH gene sequencing needs to be complemented with other more variable markers for mumps surveillance immediately after the emergence of a new genotype, but the subsequent emergence of new SH variants turns it unnecessary.

Abstract
Background With the emergence of SARS‐CoV‐2, influenza surveillance systems in Spain were transformed into a new syndromic sentinel surveillance system. The Acute Respiratory Infection Surveillance System (SiVIRA in Spanish) is based on a sentinel network for acute respiratory infection (ARI) surveillance in primary care and a network of sentinel hospitals for severe ARI (SARI) surveillance in hospitals. Methods Using a test‐negative design and data from SARI admissions notified to SiVIRA between January 1 and October 3, 2021, we estimated COVID‐19 vaccine effectiveness (VE) against hospitalization, by age group, vaccine type, time since vaccination, and SARS‐CoV‐2 variant. Results VE was 89% (95% CI: 83–93) against COVID‐19 hospitalization overall in persons aged 20 years and older. VE was higher for mRNA vaccines, and lower for those aged 80 years and older, with a decrease in protection beyond 3 months of completing vaccination, and a further decrease after 5 months. We found no differences between periods with circulation of Alpha or Delta SARS‐CoV‐2 variants, although variant‐specific VE was slightly higher against Alpha. Conclusions The SiVIRA sentinel hospital surveillance network in Spain was able to describe clinical and epidemiological characteristics of SARI hospitalizations and provide estimates of COVID‐19 VE in the population under surveillance. Our estimates add to evidence of high effectiveness of mRNA vaccines against severe COVID‐19 and waning of protection with time since vaccination in those aged 80 or older. No substantial differences were observed between SARS‐CoV‐2 variants (Alpha vs. Delta).

Abstract
OBJECTIVE Campylobacter is considered the most frequent agent of gastroenteritis in humans all around the world. The aim of this study was to know the incidence, trend and seasonality of notified campylobacteriosis cases in Castile and Leon, Spain, from 2008 to 2015. In addition, to describe the type of case and source of notification, and study the influence of age, sex and Campylobacter species on the hospitalization of cases. METHODS Retrospective cross-sectional study with a time series analysis. Data on notified campylobacteriosis cases were collected from the Epidemiological Surveillance System of Castile and Leon (2008-2015). Incidence rates and incidence rate ratios by age, sex and year of notification were calculated. In order to estimate trend and seasonality, a time series analysis was performed using a multiplicative method and adjusted to a linear and exponential model. RESULTS From 4,330 cases analyzed, 49.4% of children aged under 5 were affected. The ratio of men to women was 1.43 and 61.8% of cases were notified from secondary care. C. jejuni was isolated from 72.3% of samples (n=2,593). Incidence rate ranged from 11.42 cases per 100,000 inhabitants in 2008 to 33.53 in 2015. The seasonality range was from 71.97% (13th four-week period) to 125.54% (9th four-week period). Hospitalization reached 62.5% for people aged 60 or over. CONCLUSIONS A growing trend of notified campylobacteriosis cases is observed in Castile and Leon (2008-2015), mainly in children aged under 5, with a peak in summer months. Males are more affected than females and hospitalization increases with age.
