Infection Prevention and Control Initiatives to Prevent Healthcare-Associated Transmission of SARS-CoV-2, East Africa.

The coronavirus disease pandemic has highlighted the need to establish and maintain strong infection prevention and control (IPC) practices, not only to prevent healthcare-associated transmission of SARS-CoV-2 to healthcare workers and patients but also to prevent disruptions of essential healthcare services. In East Africa, where basic IPC capacity in healthcare facilities is limited, the US Centers for Disease Control and Prevention (CDC) supported rapid IPC capacity building in healthcare facilities in 4 target countries: Tanzania, Ethiopia, Kenya, and Uganda. CDC supported IPC capacity-building initiatives at the healthcare facility and national levels according to each country's specific needs, priorities, available resources, and existing IPC capacity and systems. In addition, CDC established a multicountry learning network to strengthen hospital level IPC, with an emphasis on peer-to-peer learning. We present an overview of the key strategies used to strengthen IPC in these countries and lessons learned from implementation.

Building a Virtual Global Knowledge Network During the Coronavirus Disease 2019 Pandemic: The Infection Prevention and Control Global Webinar Series.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has been an unprecedented global health challenge. Traditional modes of knowledge dissemination have not been feasible. A rapid solution was needed to share guidance and implementation examples within the global infection prevention and control (IPC) community. We designed the IPC Global Webinar Series to bring together subject matter experts and IPC professionals in the fight against COVID-19. METHODS: The Extension for Community Healthcare Outcomes (ECHO) model was adapted to create an interactive global knowledge network. Speakers and panelists provided presentations and answers to questions. Webinars were simultaneously interpreted into 5 languages and recorded for later access. RESULTS: Thirteen webinar sessions were completed from 14 May through 6 August 2020. On average, 634 participants attended each session (range, 393-1181). Each session was represented by participants from, on average, more than 100 countries. CONCLUSIONS: Through the IPC Global Webinar Series, critical information was shared and peer-to-peer learning was promoted during the COVID-19 pandemic response. The webinar sessions reached a broader audience than many in-person events. The webinar series was rapidly scaled and can be rapidly reactivated as needed. Our lessons learned in designing and implementing the series can inform the design of other global health virtual knowledge networks. The continued and expanded use of adapted virtual communities of practice and other learning networks for the IPC community can serve as a valuable tool for addressing COVID-19 and other infectious disease threats.The infection prevention and control (IPC) Global Webinar Series convened subject matter experts and IPC professionals from more than 100 countries to establish a global learning community for COVID-19. We advocate for expanded use of virtual knowledge networks.

HPV Vaccine-Related Research, Promotion and Coordination in the State of Georgia: A Systematic Review.

Human papillomavirus (HPV) vaccine was first recommended for female adolescents in the United States in 2006, and for male adolescents in 2011. In 2016, national HPV vaccine coverage was 43.4%, and slightly higher in Georgia (45.6%). Little is known about sub-state-level variation in HPV vaccination or Georgia specific research conducted to improve HPV vaccine uptake. We aimed to describe current uptake of HPV vaccination and synthesize Georgia-specific research of HPV vaccine uptake. We reviewed existing published and grey literature for different development, implementation and best practices related to vaccine uptake in adolescents. Studies measuring HPV vaccine uptake in Georgia utilizing quantitative, qualitative, or mixed-methods approaches were included alongside state-level information from National Immunization Survey-Teen, Community Health Needs Assessments, Behavioral Risk Factor Surveillance and Georgia Adolescent Immunization Surveys. Key findings across these reports were summarized. Forty-two titles and abstracts were identified through electronic database search for literature published between 2006 and 2017. Of these, five were from database sources and 37 were from additional sources. The most often mentioned barriers of HPV vaccine uptake in Georgia include cultural norms, vaccination education and a misalignment of vaccine uptake goals between the state and regional hospital community needs assessments. Increasing knowledge and uptake of HPV vaccine in Georgia requires significant research and to understand the vast socioeconomic, cultural and geographic barriers preventing uptake among adolescents. Georgia-specific efforts have been limited, however ongoing collaborations spearheaded by the Georgia Cancer Control Coalition provide opportunities for state-level support of research to address these barriers.

A survey of state and local practices encouraging pediatric COVID-19 vaccination of children ages 6 months through 11 years.

OBJECTIVE: This report highlights state and local practices for optimizing the pediatric COVID-19 vaccination program for children ages 6 months through 11 years. METHODS: State and local practices designed to optimize pediatric COVID-19 vaccine uptake were identified from a range of sources, including immunization program, CDC, and partner staff; and media stories or program descriptions identified via online searches. RESULTS: A range of practices were identified across different categories: provider-focused practices, school-based practices, jurisdiction or health department-based activities, community-focused practices involving partners, use of vaccination incentives, and Medicaid-related practices. CONCLUSIONS: Immunization programs and stakeholders implemented a variety of practices to meet the challenge of the pediatric COVID-19 vaccination program. The key findings may serve to inform not only the current pediatric COVID-19 vaccination program, but also future outbreak response work and routine immunization activities.

Mycobacterium leprae-helminth co-infections and vitamin D deficiency as potential risk factors for leprosy: A case-control study in south-eastern Brazil.

BACKGROUND: Evidence suggests that biological mechanisms involved in helminth infections and vitamin deficiencies increase susceptibility to other infections. The aim of this study was to investigate the associations of helminth co-infection and select micronutrient deficiencies with leprosy using a case-control design. METHODS: From 2016 to 2018, individuals aged ≥3 years were recruited at clinics in and around Governador Valadares, Minas Gerais, Brazil in three groups: cases of leprosy, household contacts and community-matched (non-contact) controls. Helminths were diagnosed through stool Kato Katz examination and serum reactivity to anti-soluble adult worm antigen preparation IgG4. Serum ferritin, 25-OH vitamin D and retinol concentrations were measured. Multi-variate logistic regression was conducted to identify associations with active leprosy. RESULTS: Seventy-nine cases of leprosy, 96 household contacts and 81 non-contact controls were recruited; 48.1% of participants were male with a median age of 40 years. Helminths were found in 7.1% of participants on Kato Katz test, all but one of which were Schistosoma mansoni, and 32.3% of participants were positive for S. mansoni serology. On multi-variate analysis, cases were more likely to be infected with helminths (diagnosed by stool) than household contacts [adjusted odds ratio (aOR) 8.69, 95% confidence interval (CI) 1.50-50.51]. Vitamin D deficiency was common, and was more likely in cases compared with non-contact controls (aOR 4.66, 95% CI 1.42,-15.33). Iron deficiency was not associated with leprosy, and vitamin A deficiency was not detected. CONCLUSION: These associations suggest that the immune consequences of schistosomiasis and vitamin D deficiency may increase the risk of active leprosy. Comorbid conditions of poverty deserve further study as addressing co-infections and nutritional deficiencies could be incorporated into programmes to improve leprosy control.
