Residual blood specimens collected at health facilities may be a source of samples for serosurveys of adults, a population often neglected in community-based serosurveys. Anonymized residual blood specimens were collected from individuals 15 - 49 years of age attending two sub-district hospitals in Palghar District, Maharashtra, from November 2018 to March 2019. Specimens also were collected from women 15 - 49 years of age enrolled in a cross-sectional, community-based serosurvey representative at the district level that was conducted 2 - 7 months after the residual specimen collection.

- Residual blood specimens offer a cost-effective way to track seroprevalence changes compared to traditional household surveys, as shown in a study in India focused on measles-rubella vaccinations.
- A cross-sectional survey in Kanpur Nagar and Palghar found significant increases in rubella seroprevalence post-immunization, though measles trends were inconsistent between facility and community samples.
- Younger children in public facilities initially had lower rubella seroprevalence than those in private hospitals, but this gap disappeared after the vaccination campaign, highlighting the importance of residual specimens for public health monitoring.
Background: In alignment with the Measles and Rubella (MR) Strategic Elimination plan, India conducted a mass measles and rubella vaccination campaign across the country between 2017 and 2020 to provide a dose of MR containing vaccine to all children aged 9 months to 15 years. We estimated campaign vaccination coverage in five districts in India and assessed campaign awareness and factors associated with vaccination during the campaign to better understand reasons for not receiving the dose.
Methods And Findings: Community-based cross-sectional serosurveys were conducted in five districts of India among children aged 9 months to 15 years after the vaccination campaign.
Article Synopsis
- The study examines the relationship between chitin properties in stored-product insect pests and their vulnerability to garlic essential oil toxicity.
- Different techniques were used to analyze chitin from three insect species, revealing that S. oryzae has the highest chitin content and crystallinity, which may contribute to its resistance against the fumigant.
- Fumigant toxicity tests showed C. maculatus is more susceptible to garlic essential oil compared to the other species, highlighting the potential link between chitin characteristics and insect susceptibility to bioactive substances.
This work focuses on the profiling of semiochemicals (SCS) from , and by headspace solid-phase microextraction (HS-SPME) coupled with gas chromatography-mass spectrometry (GC-MS) technique. Totally, 6, 9 and 8 volatile compounds (VCS) were detected from , and , respectively. As a result of pherobase analysis and preference bioassay, stearic acid (); nonanal, lauric acid and stearic acid (); stearic acid () were identified as new SCS that could be useful for integrated pest management (IPM) practices.
