SARS-CoV-2 Omicron Replacement of Delta as Predominant Variant, Puerto Rico.

We reconstructed the SARS-CoV-2 epidemic caused by Omicron variant in Puerto Rico by sampling genomes collected during October 2021-May 2022. Our study revealed that Omicron BA.1 emerged and replaced Delta as the predominant variant in December 2021. Increased transmission rates and a dynamic landscape of Omicron sublineage infections followed.

The purpose of this special report is to describe chronologically the events that contributed to the development and approval of legislation and subsequent implementation of a school vaccination mandate in order to prevent HPV and HPV-associated cancers in Puerto Rico (PR). Starting in 2010, PR initiated public-policy approvals aimed at improving cancer registries and HPV vaccine coverage through health insurance for adolescents aged 11 to 18 years. In 2014, scientific and community efforts succeeded in documenting the magnitude of morbidity caused by HPV and jointly developing HPV vaccine prevention and promotion strategies. In August 2018, PR became one of the first four territories of the United States of America to implement the HPV vaccine school entry requirement to decrease the incidence of HPV-associated cancers on the island. In 2019, it was enshrined in law that every immunization provider must submit immunization data to the Puerto Rico Immunization Registry. The case of PR demonstrates that public policy-making alongside collaboration between academic, scientific, and community coalitions can achieve population change and measurable outcomes aimed at HPV prevention. Countries with a similar public health problem could adopt efforts similar to those presented herein and align them with the World Health Organization goal of eradicating cervical cancer by 2030.

Restoring Immunization Services Provided by the Vaccines for Children Program in Puerto Rico After Hurricanes Irma and Maria, 2017-2019.

CONTEXT: In September 2017, Hurricanes Irma and Maria impacted Puerto Rico, causing significant disruption of immunization services and vaccine losses due to widespread infrastructure and electrical grid damage and resulting cold chain failures. OBJECTIVE: To describe posthurricane efforts undertaken to restore and strengthen immunization services provided by Puerto Rico's federally funded Vaccines for Children (VFC) Program, a network of clinics that provide vaccines to eligible children. DESIGN: Historical records were reviewed to characterize Puerto Rico's prehurricane immunization system. Site visits to assess VFC clinic posthurricane operational status were conducted by the Puerto Rico Department of Health, working with the Centers for Disease Control and Prevention and other partners. Infrastructure repair and acquisition of backup generators, temperature data loggers, and replacement vaccines were carried out to restore operations. RESULTS: Prior to the hurricanes, 224 VFC clinics throughout the island provided immunizations. An initial assessment 10 days after Hurricane Maria showed that only 11 (5%) of the clinics were operational. Reasons included ongoing power outages; difficulties in obtaining generator fuel; equipment or facility damage; and damaged vaccines. The VFC clinics were restored incrementally; 123 (55%) were operational by December 2017, 193 (86%) by May 2018, and 204 (91%) by May 2019. Long-term recovery activities are underway and focus on strengthening Puerto Rico's immunization system to withstand future disasters, including improving backup power systems. CONCLUSION: Through coordinated efforts of the Puerto Rico Department of Health, the Centers for Disease Control and Prevention, and other partners, the operational status of VFC clinics posthurricanes was assessed and operations restored. Emergency plans for vaccine storage and handling, which called for alternative vaccine storage locations and backup generators, were inadequate to address disasters of the magnitude of Hurricanes Irma and Maria; such plans need to consider the possibility of large-scale disasters that result in long-term power outages.

Genomic surveillance of SARS-CoV-2 in Puerto Rico reveals emergence of an autochthonous lineage and early detection of variants.

Puerto Rico has experienced the full impact of the COVID-19 pandemic. Since SARS-CoV-2, the virus that causes COVID-19, was first detected on the island in March of 2020, it spread rapidly though the island’s population and became a critical threat to public health. We conducted a genomic surveillance study through a partnership with health agencies and academic institutions to understand the emergence and molecular epidemiology of the virus on the island. We sampled COVID-19 cases monthly over 19 months and sequenced a total of 753 SARS-CoV-2 genomes between March 2020 and September 2021 to reconstruct the local epidemic in a regional context using phylogenetic inference. Our analyses revealed that multiple importation events propelled the emergence and spread of the virus throughout the study period, including the introduction and spread of most SARS-CoV-2 variants detected world-wide. Lineage turnover cycles through various phases of the local epidemic were observed, where the predominant lineage was replaced by the next competing lineage or variant after approximately 4 months of circulation locally. We also identified the emergence of lineage B.1.588, an autochthonous lineage that predominated circulation in Puerto Rico from September to December 2020 and subsequently spread to the United States. The results of this collaborative approach highlight the importance of timely collection and analysis of SARS-CoV-2 genomic surveillance data to inform public health responses.

Assessment of COVID-19 Vaccination Practices for 16 Vaccination Providers in Puerto Rico, 2021.

OBJECTIVE: To assess COVID-19 vaccine providers' adherence to best practices and identify knowledge and practice gaps to guide corrective actions and retraining activities in Puerto Rico. METHODS: A CDC supportive evaluation tool was modified to collect information on vaccine storage, handling, preparation, administration, and post-vaccination care. Assessment visits to COVID-19 vaccine providers in Puerto Rico were conducted a month after the availability of COVID-19 vaccines in the island. RESULTS: A total 16 vaccine providers were visited, 12 (75%) administering Pfizer-BioNTech vaccine and 4 (25%) administering Moderna vaccine. All providers adhered to correct handling practices after vaccine thawing. Required resources for managing anaphylaxis on site were available in all sites. Few instances of incorrect use of retractable-needle syringes, unapproved temperature monitoring devices, and lack of recorded temperature data were observed. Corrective actions were taken during the evaluation visit. CONCLUSION: No major deficiencies that could jeopardize vaccine viability or patient safety were found. The use of a supportive evaluation tool during assessment visits is helpful to determine needs for vaccine providers retraining and to continue the safe administration of COVID-19 vaccines in Puerto Rico.

Prior Dengue Virus Infection Is Associated With Increased Viral Load in Patients Infected With Dengue but Not Zika Virus.

To evaluate potential enhancement of Zika virus (ZIKV) infection among patients with prior dengue virus (DENV) infection, we compared loads of viral RNA among patients infected with ZIKV (n = 1070), DENV-2 (n = 312), or DENV-3 (n = 260). Compared to patients without prior DENV infection, patients with prior DENV infection had significantly higher mean loads of viral RNA if infected with DENV-2 (10.6 vs 11.6 log10 GCE/mL, respectively; t test, P < .0001) or DENV-3 (10.3 vs 10.9 log10 GCE/mL; P < .0001), but not ZIKV (4.7 vs 4.7 log10 GCE/mL; P = .959). These findings provide evidence against in vivo enhancement of ZIKV by anti-DENV antibodies.

RESUMEN El propósito de este informe especial es describir cronológicamente los eventos que contribuyeron al desarrollo y aprobación de la legislación e implementación del requisito escolar de vacunación en Puerto Rico (PR), con el fin de prevenir el VPH y los cánceres asociados a este. A partir del 2010, PR inició las aprobaciones de políticas públicas con el objetivo de mejorar el registro de casos de los cánceres y la cobertura de la vacuna contra el VPH a través de los planes médicos en adolescentes de 11 a 18 años. En el 2014, los esfuerzos científicos y comunitarios lograron documentar la magnitud de las enfermedades causadas por el VPH, y desarrollar en conjunto, estrategias de prevención y promoción de la vacuna contra el VPH. En agosto de 2018, PR logró ser uno de los primeros cuatro territorios de los Estados Unidos de América en implementar la vacuna contra el VPH como requisito escolar con el fin de disminuir la incidencia de cánceres asociados al VPH en la isla. En el 2019 se garantizó por ley que todo proveedor de vacunación debe reportar al Registro de Inmunización. El caso de PR demuestra que el desarrollo de políticas públicas junto con colaboraciones entre coaliciones académicas, científicas y comunitarias, logran cambios poblacionales y resultados medibles dirigidos a la prevención de VPH. Países con una problemática de salud pública similar podrían adoptar esfuerzos similares a los presentados, y alinearlos al objetivo de la Organización Mundial de la Salud: erradicación del cáncer cervical para 2030.
