How the Commonwealth of the Northern Mariana Islands stalled COVID-19 for 22 months and managed its first significant community transmission.

Objective: The Commonwealth of the Northern Mariana Islands (CNMI) is a remote Pacific island territory with a population of 47 329 that successfully prevented the significant introduction of coronavirus disease (COVID-19) until late 2021. This study documents how the response to the introduction of COVID-19 in CNMI in 2021 was conducted with limited resources without overwhelming local clinical capacity or compromising health service delivery for the population. Methods: Data from COVID-19 case investigations, contact tracing, the Commonwealth's immunization registry and whole genome sequencing were collated and analysed as part of this study. Results: Between 26 March 2020 and 31 December 2021, 3281 cases and 14 deaths due to COVID-19 were reported in CNMI (case fatality rate, 0.4%). While notification rates were highest among younger age groups, hospitalization and mortality rates were disproportionately greater among those aged > 50 years and among the unvaccinated. The first widespread community transmission in CNMI was detected in October 2021, with genomic epidemiology and contact tracing data indicating a single introduction event involving the AY.25 lineage and subsequent rapid community spread. Vaccination coverage was high before widespread transmission occurred in October 2021 and increased further over the study period. Discussion: Robust preparedness and strong leadership generated resilience within the public health sector such that COVID-19 did not overwhelm CNMI's health system as it did in other jurisdictions and countries around the world. At no point was hospital capacity exceeded, and all patients received adequate care without the need for health-care rationing.

Community Perspectives on Contraception in the Context of Zika Virus in American Samoa and the Commonwealth of the Northern Mariana Islands.

The prevention of unintended pregnancy was identified as a primary prevention strategy to reduce Zika-related adverse birth outcomes during the 2016-2017 Zika virus outbreak. The Centers for Disease Control and Prevention in partnership with local health agencies conducted formative research to guide the development of culturally appropriate messages and materials to increase awareness of the prevention of unintended pregnancy as a strategy to decrease Zika-related adverse outcomes in American Samoa and the Commonwealth of the Northern Mariana Islands (CNMI). Nine focus groups (N=71) were conducted with women and men aged 18-44 years living in American Samoa and CNMI. Semi-structured interview guides were used to explore participants' knowledge and perceptions of Zika, family planning, and contraception; barriers and facilitators to access contraception and use; and information sources and contraception decision-making. Trained staff from local organizations co-moderated each focus group. Thematic analysis was conducted with NVivo 10. Participants had mixed knowledge about Zika virus and its relation to pregnancy and birth defects. Women and men had varied knowledge of the full range of contraceptive methods available in their jurisdiction and identified barriers to contraceptive access. Social factors including stigma, gender roles, and religion often deterred participants from accessing contraceptive services. Participants highlighted the need for culturally appropriate and clear messaging about contraceptive methods. Results demonstrate the feasibility of conducting formative research as an effective strategy for understanding community perspectives on unintended pregnancy prevention in the context of the Zika virus outbreak to develop health communication materials.
