Introduction: Mumps is a vaccine-preventable disease caused by the paramyxovirus affecting the salivary gland and may be complicated by orchitis, oophoritis, and encephalitis. This study aims to describe the epidemiology, clinical presentation, and transmission of mumps cases in the Kingdom of Bahrain between 2012 and 2022.
Methodology: A retrospective cross-sectional study was conducted using national surveillance data of confirmed mumps cases, including all age groups and both Bahraini and non-Bahraini nationals, from January 2012 to December 2022.
Results: A total of 258 cases were recorded, with the majority being male (159, 61.6%). Most patients (255, 98.8%) presented with parotid gland swelling, and 9 (3.5%) required hospitalization. Only 63 (24%) patients had documented vaccination history. Incidence rates varied, with peaks in 2013, 2015, and 2019. The highest incidence was observed in children aged 0-4 years in 2012, shifting to the 5-14 years age group from 2013 to 2015, and then returning to the 0-4 years age group from 2016 to 2022. Overall, there is a downward trend in mumps cases in Bahrain.
Conclusions: The study shows a declining trend in mumps incidence in Bahrain. The high incidence in young children emphasizes the need to maintain high vaccination coverage. Enhanced surveillance, timely outbreak investigations, interventions, and public health vaccine campaigns are essential to sustain progress. This comprehensive analysis provides baseline data and a foundation for strengthening mumps prevention and control efforts in Bahrain.

Objectives: Mumps (infectious parotitis) is an acute respiratory illness caused by the mumps virus in humans. While numerous studies have explored the impact of climate variability on mumps incidence in specific cities or regions, few have analyzed nationwide associations across multiple locations. This study aims to systematically assess the short-term effects of meteorological factors on mumps incidence across Japan over a 15-year period.

The AEP 2025 Vaccination and Immunization Schedule recommended for children, adolescents and pregnant women residing in Spain features the following novelties: Due to the increase in measles cases and outbreaks in recent years, we recommend advancing the second dose of measles, mumps and rubella (MMR) vaccine to 2 years of age. As a consequence of the above, since many autonomous communities (ACs) use the quadrivalent vaccine for the second dose of MMR and varicella vaccines, we recommend, for all ACs, advancing the second dose of varicella vaccine to 2 years of age. Due to the very significant increase in cases of pertussis since late 2023 and especially in 2024, we recommend advancing the dose of Tdap given in adolescence to 10-12 years of age.

In 2015, the 62nd session of the Regional Committee [RC] of the Eastern Mediterranean Region [EMR] endorsed the Eastern Mediterranean Vaccine Action Plan 2016-2020 (EMVAP) that included postponement of the measles elimination target to before 2020. However, the EMR does not have a regional rubella control or elimination goal. We reviewed the progress of measles and rubella surveillance in context of measles elimination in the Eastern Mediterranean Region during 2019-2022.

Article Synopsis
- Mumps is primarily a childhood infection characterized by swollen parotid glands, but a recent outbreak in Chile affected adults aged 20-35 despite the earlier success of the triple virus vaccine.
- During 2018-2019, researchers analyzed 592 suspected mumps cases, finding a significant percentage positive for mumps antibodies (19.8% IgM and 95.9% IgG), with a notable male majority among positive IgM cases.
- Genetic analysis revealed G and N genotypes in some cases, highlighting the importance of laboratory findings in diagnosing mumps and understanding the outbreak through an epidemiological surveillance program.
