Passion fruit (Passiflora edulis) leaves displaying yellow spot symptoms were collected in La Réunion. Whilst viral indexing suggested single infections with potyviruses, high-throughput sequencing revealed both single and mixed infections involving cowpea aphid-borne mosaic virus (CABMV; species Potyvirus vignae) and a previously undescribed potyvirus, for which the name passion fruit yellow spot virus (PaYSV; tentative species Potyvirus passifloraflavamaculae) is proposed. Complete genome sequences (9,626 nucleotides) of two PaYSV isolates were obtained from these samples, using RNA sequencing after ribodepletion. The two isolates were highly similar (> 99.3% nucleotide identity) and shared the highest nucleotide (63.6%) and amino acid (71.7%) identities at the polyprotein level with passion fruit woodiness virus (PWV; Potyvirus passiflorae), values that are below the species demarcation thresholds. Our results provide compelling molecular and phylogenetic evidence for the presence of a novel potyvirus species infecting passion fruit in La Réunion.

Behavioural and Structural Determinants of Mpox Vaccine Awareness and Uptake Among People With HIV in the Dominican Republic: A Cross-Sectional Study.

Paulino-Ramirez Robert R, Matias Wilfredo R WR, Chaumette Alexandre A, Lora-Rodríguez Hector H et al.

Mpox disproportionately affects people with HIV (PWH), yet little is known about mpox vaccine awareness and uptake in low- and middle-income countries. We evaluated mpox-related knowledge, attitudes and practices (KAP) among PWH in the Dominican Republic to identify determinants of vaccine awareness and uptake. We conducted a cross-sectional online survey of 98 PWH recruited through HIV clinics, community-based organizations and social networks (January-May 2025). The questionnaire assessed sociodemographic characteristics, mpox-related KAP, structural barriers and vaccination status. Univariable and multivariable logistic regression were used to examine factors associated with mpox vaccine awareness. Half of the participants (49/98) were aware of the mpox vaccine. Individuals aged 31-40 years had significantly lower odds of awareness compared with those aged 21-30 years. Despite high levels of formal education, 79% rated their mpox knowledge as low, and most perceived minimal personal risk. Among participants aware of the vaccine, 71% had been vaccinated. Structural barriers, including inconvenient site locations and logistical challenges, were frequently reported, even among vaccinated individuals, indicating that access limitations rather than hesitancy were the dominant constraints. Trust in vaccinating organizations was high overall, and healthcare providers and community organizations were the primary sources of vaccine information. Peer and community influence emerged as notable facilitators of uptake, while lack of reliable information and concerns about vaccine safety contributed to hesitancy. Mpox vaccine awareness among PWH in the Dominican Republic was low, but willingness to vaccinate was high when individuals were informed and able to access services. Strengthening mpox preparedness will require expanding accessible vaccination sites, improving disease-specific health literacy, and leveraging trusted community and clinical networks. Integrating mpox vaccination into routine HIV care delivery and enhancing community-led outreach may substantially improve uptake in this and similar low-middle income countries (LMIC) settings.

Pneumococcal pneumonia in adults - re-emergence of vaccine serotypes: a prospective multicenter cohort study in Germany, 2020-2023.

The main burden of non-invasive pneumococcal diseases in adults is largely due to community-acquired pneumonia (CAP). This study aimed to investigate the distribution and dynamics of pneumococcal vaccine serotypes and to determine the proportion of CAP cases attributable to serotypes covered by 13-valent conjugate vaccine (PCV13), the 20-valent conjugate vaccine (PCV20), and the 23-valent polysaccharide vaccine (PPV23) among adults in Germany from 2020 to 2023. In this prospective multicenter cohort study, we analyzed all adult patients with CAP enrolled between January 1, 2020, and December 31, 2023, at 26 centers in Germany who provided urine samples for serotype-specific urine antigen detection (SSUAD) testing. Annual trends of pneumococcal vaccine serotypes from 2020 to 2023 were calculated for all patients and patient groups at risk using cluster-robust generalized linear models with heteroscedasticity-consistent standard errors. Of the 2,028 patients with all-cause CAP, 1,504 (1,008 patients aged ≥ 60 years, 373 younger patients with at least one comorbidity) had urine samples analyzed with SSUAD tests. Overall proportion of vaccine-type pneumococcal pneumonia among all-cause CAP for PCV13, PCV20, and PPV23 serotypes was 5.41% (95% CI 4.12-7.06%), 8.11% (95% CI 6.35-10.31%), and 8.31% (95% CI 6.27-10.93%), and serotype 3 was the most prevalent serotype (52 cases). Among patients aged ≥ 60 years, an increasing annual trend was observed for serotype 3 (OR 1.84, 95% CI 1.01-2.67), PCV13 (OR 1.89, 95% CI 0.89-2.89), PCV20 (OR 1.57, 95% CI 0.99-2.14), and PPV23 serotypes (OR 1.47, 1.04-1.91). The findings demonstrate that vaccine serotypes, particularly serotype 3, continued to circulate and reemerged among older adults with CAP in Germany.
