SARS-CoV-2 Infections in Vaccinated and Unvaccinated Populations in Camp Lemonnier, Djibouti, from April 2020 to January 2022.

The global pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has highlighted the disparity between developed and developing countries for infectious disease surveillance and the sequencing of pathogen genomes. The majority of SARS-CoV-2 sequences published are from Europe, North America, and Asia. Between April 2020 and January 2022, 795 SARS-CoV-2-positive nares swabs from individuals in the U.S. Navy installation Camp Lemonnier, Djibouti, were collected, sequenced, and analyzed. In this study, we described the results of genomic sequencing and analysis for 589 samples, the first published viral sequences for Djibouti, including 196 cases of vaccine breakthrough infections. This study contributes to the knowledge base of circulating SARS-CoV-2 lineages in the under-sampled country of Djibouti, where only 716 total genome sequences are available at time of publication. Our analysis resulted in the detection of circulating variants of concern, mutations of interest in lineages in which those mutations are not common, and emerging spike mutations.

Promoting Oral Health in Appalachia: Effects of Threat Label and Source Accent on Message Acceptance.

This study examined the effects of threat label (i.e., the name assigned to a health threat) and source accent (i.e., the source's manner of pronunciation) on Appalachian residents' acceptance of oral health promotion messages. Participants (N = 348) listened to an audiotaped oral health promotion message about tooth decay or Mountain Dew Mouth; the message was delivered either in a standard American English or a Southern accent. Compared to the label Mountain Dew Mouth, the label tooth decay elevated perceptions of threat susceptibility, threat severity, and response-efficacy and resulted in higher message acceptance. The effect of threat label on message acceptance was mediated by severity perceptions. Participants attributed more status to the source and agreed more with her message when she spoke in a standard than a Southern accent. The effect of source accent on message acceptance was mediated by status perceptions. These findings suggest that the success of persuasive health messages depends not only on message content (i.e., what is said), but also on how that content is linguistically framed and delivered (i.e., how it is said).
