On May 15, 2014, CDC was notified of two laboratory-confirmed measles cases in the Federated States of Micronesia (FSM), after 20 years with no reported measles. FSM was assisted by the World Health Organization (WHO), the United Nations Children’s Fund (UNICEF), and CDC in investigating suspected cases, identify contacts, conduct analyses to guide outbreak vaccination response, and review vaccine cold chain practices. During February–August, three of FSM’s four states reported measles cases: Kosrae (139 cases), Pohnpei (251), and Chuuk (3). Two thirds of cases occurred among adults aged ≥20 years; of these, 49% had received ≥2 doses of measles-containing vaccine (MCV). Apart from infants aged <12 months who were too young for routine vaccination, measles incidence was lower among children than adults. A review of current cold chain practices in Kosrae revealed minor weaknesses; however, an absence of historical cold chain maintenance records precluded an evaluation of earlier problems. Each state implemented vaccination campaigns targeting children as young as age 6 months through adults up to age 57 years. The preponderance of cases in this outbreak associated with vaccine failure in adults highlights the need for both thorough case investigation and epidemiologic analysis to guide outbreak response vaccination. Routine childhood vaccination coverage achieved in recent years limited the transmission of measles among children. Even in areas where transmission has not occurred for years, maintaining high 2-dose MCV coverage through routine and supplemental immunization is needed to prevent outbreaks resulting from increased measles susceptibility in the population.

Dengue is a potentially fatal acute febrile illness caused by four mosquito-transmitted dengue viruses (DENV-1-4). Although dengue outbreaks regularly occur in many regions of the Pacific, little is known about dengue in the Republic of the Marshall Islands (RMI). To better understand dengue in RMI, we investigated an explosive outbreak that began in October 2011. Suspected cases were reported to the Ministry of Health, serum specimens were tested with a dengue rapid diagnostic test (RDT), and confirmatory testing was performed using RT-PCR and IgM ELISA. Laboratory-positive cases were defined by detection of DENV nonstructural protein 1 by RDT, DENV nucleic acid by RT-PCR, or anti-DENV IgM antibody by RDT or ELISA. Secondary infection was defined by detection of anti-DENV IgG antibody by ELISA in a laboratory-positive acute specimen. During the four months of the outbreak, 1,603 suspected dengue cases (3% of the RMI population) were reported. Of 867 (54%) laboratory-positive cases, 209 (24%) had dengue with warning signs, six (0.7%) had severe dengue, and none died. Dengue incidence was highest in residents of Majuro and individuals aged 10-29 years, and ∼95% of dengue cases were experiencing secondary infection. Only DENV-4 was detected by RT-PCR, which phylogenetic analysis demonstrated was most closely related to a virus previously identified in Southeast Asia. Cases of vertical DENV transmission, and DENV/Salmonella Typhi and DENV/Mycobacterium leprae co-infection were identified. Entomological surveys implicated water storage containers and discarded tires as the most important development sites for Aedes aegypti and Ae. albopictus, respectively. Although this is the first documented dengue outbreak in RMI, the age groups of cases and high prevalence of secondary infection demonstrate prior DENV circulation. Dengue surveillance should continue to be strengthened in RMI and throughout the Pacific to identify and rapidly respond to future outbreaks.

Background: In 2007, physicians on Yap Island reported an outbreak of illness characterized by rash, conjunctivitis, and arthralgia. Although serum from some patients had IgM antibody against dengue virus, the illness seemed clinically distinct from previously detected dengue. Subsequent testing with the use of consensus primers detected Zika virus RNA in the serum of the patients but no dengue virus or other arboviral RNA. No previous outbreaks and only 14 cases of Zika virus disease have been previously documented., Methods: We obtained serum samples from patients and interviewed patients for information on clinical signs and symptoms. Zika virus disease was confirmed by a finding of Zika virus RNA or a specific neutralizing antibody response to Zika virus in the serum. Patients with IgM antibody against Zika virus who had a potentially cross-reactive neutralizing-antibody response were classified as having probable Zika virus disease. We conducted a household survey to estimate the proportion of Yap residents with IgM antibody against Zika virus and to identify possible mosquito vectors of Zika virus., Results: We identified 49 confirmed and 59 probable cases of Zika virus disease. The patients resided in 9 of the 10 municipalities on Yap. Rash, fever, arthralgia, and conjunctivitis were common symptoms. No hospitalizations, hemorrhagic manifestations, or deaths due to Zika virus were reported. We estimated that 73% (95% confidence interval, 68 to 77) of Yap residents 3 years of age or older had been recently infected with Zika virus. Aedes hensilli was the predominant mosquito species identified., Conclusions: This outbreak of Zika virus illness in Micronesia represents transmission of Zika virus outside Africa and Asia. Although most patients had mild illness, clinicians and public health officials should be aware of the risk of further expansion of Zika virus transmission., (2009 Massachusetts Medical Society)

Context: The University of Hawai'i Pacific Basin Bioterrorism Curriculum Development Project has developed a problem-based learning (PBL) curriculum for teaching health professionals and health professional students about bioterrorism and other public health emergencies. These PBL cases have been incorporated into interdisciplinary training settings in community-based settings, such as in the small island districts of the U.S.-Affiliated Pacific Islands., Methods: Quantitative and qualitative methods have been utilized in the evaluation of the PBL cases, PBL tutorials, and the accomplishment of learning objectives., Findings: Evaluation of the PBL tutorials demonstrates that PBL is an educational and training modality appropriate for such settings. Participants found it helpful to learn in interdisciplinary groups. The educational process was modified in accordance with local culture., Conclusion: PBL is a useful educational modality for settings where healthcare staffing and available resources are limited.

In 2003, the University of Hawai'i Department of Family Medicine and Community Health entered a 4-year cooperative agreement with the U.S. Health Resources and Services Administration to establish the "Pacific Association for Clinical Training" (PACT). PACT's goal is to develop effective distance education methods to improve the education and skills of health care professionals in the U.S.-Affiliated Pacific Island nations. To determine the situation existing in 2004, one of PACT's first projects was to perform site visits to each jurisdiction, conducting needs assessments through interviews with key health care professionals, hospital administrators and government officials. This article highlights findings of PACT's Palau assessment. Meant to establish a baseline for future reference, all data were collected in 2004-2005 and have not been updated.

We survey Indigenous health issues across the Pacific with a case study approach that focuses on Australia, New Zealand, Hawai'i, and US Associated Micronesia. For each case study, we provide an overview of the Indigenous population, its colonial history, and current health and social outcomes. In the discussion that follows, we flag some of the key policy initiatives that have been developed to address Indigenous health disadvantage, albeit within the context of continuing debates about Indigenous rights and policy.

Rapidly increasing tobacco use in developing countries will result in a large and increasing burden of tobacco-related illnesses as their populations age. The Republic of the Marshall Islands (RMI) is an island nation in the Pacific with a 1999 census population of 50,840, of whom more than fifty percent were under twenty years of age. There are limited data on the prevalence of smoking among youth in the RMI. A school survey of 3,294 RMI students in grades 5 through 12 was conducted in 2000. Urban and outer atoll schools were included in the sample. Demographic data and information on tobacco use and risk factors were collected. The overall smoking rate in this school sample was 10.6%. There were significantly higher smoking rates in the high school age group; the rate of smoking among 18 year olds was 33.5%. Smoking rates were higher among males compared to females (18.7% vs. 3.4%) and higher among outer atoll students compared to urban students (14.5% vs. 9.4%). The most prominent risk factors for smoking were: age, male gender, receiving or wearing tobacco-labeled equipment or clothing and willingness to participate in other high-risk behaviors. The survey provides an estimate of smoking rates among Marshallese school students and identifies and quantifies significant risk factors for smoking. This information can assist in guiding a comprehensive tobacco control strategy in the Republic of the Marshall Islands.

The purpose of this study was to use a low-cost method of estimating prevalence of diabetes mellitus for a small island population receiving medical care from a single facility. A suitable sample of 692 (16.4%) from a total of 4,223 medical records of Ebeye Island Marshallese adult outpatients 30 or more years of age was reviewed in July and August 2000 for evidence of diabetes mellitus. Diagnosed diabetes was defined as having a diagnosis of diabetes noted in the chart. In patients without a diagnosis of diabetes, undiagnosed diabetes was defined as one fasting whole blood glucose > or = 70 mmol/l (126 mg/dl) or one random whole blood glucose > or = 11.1 mmol/l (200 mg/dl). Impaired fasting glucose was defined as one fasting whole blood glucose 6.1-7.0 mmol/l (110-125 mg/dl). For this population of adults 30 or more years in age, the crude prevalence of diabetes [diagnosed cases 13% (confidence interval, CI = 10-15%) and undiagnosed cases 6.9% (CI = 5.0-8.8%)] was 20% (CI = 17-23%). As the population of Ebeye is younger than the world population, adjustment to a standard world population gives an age-adjusted prevalence of diabetes in adults 30 or more years of age of 27%, and an age-adjusted prevalence in adults 20 or more years of age of 20%. In comparison, the crude prevalence of diagnosed and undiagnosed diabetes in the U.S. in adults 20 or more years of age is 8.3%, and the worldwide prevalence in adults 20 or more years of age is 4.0%. Limitations of our methodology include lack of randomization, lack of access to proper laboratory equipment, and passive case-finding, necessitating revision of standard diagnostic criteria. Prevalence rates of diabetes in Marshallese outpatients are thus significantly higher than US or worldwide rates. In addition, there are many cases of undiagnosed diabetes in the RMI. Recommended are a cross-sectional serosurvey of a large age- and gender-stratified population, increased resources to care for people with diabetes, and public health interventions to improve nutrition and facilitate physical activity in order to lower the prevalence of diabetes. The large-scale social forces that lead to diabetes need to be addressed accordingly.
