The objective of this paper was to investigate who had published papers about emergencies and disasters (events) in the last five years. This was not intended to be a full systematic review, rather an assessment of the location of authors of papers published on these events.

Objectives: Early studies on COVID-19 vaccine hesitancy showed varied intensity across countries, which was linked to various factors such as socio-economic conditions, information sources, and issues of trust in government, scientific experts, and the health sector. This study aims to evaluate the determinants of vaccine hesitancy to offer insights into the strategies that may be successful in designing communications campaigns for enhanced vaccination uptake. Methods: Through logistic regression, this study examines correlates of survey data from five Southeast Asian countries, namely Indonesia (ID), Malaysia (MY), Philippines (PH), Thailand (TH), Vietnam (VN) collected by the Massachusetts Institute of Technology Initiative on Digital Economy and Facebook between July 2020 and March 2021. Results: Some significant determinants at the 5% or 1% level of significance of COVID-19 vaccine hesitancy in the countries of interest include gender [ID: 1.17 (1.01, 1.15), MY: 1.35 (1.2,1.53), PH: 1.92 (1.68,2.19), VN: 1.28 (1.04,1.58)], age [MY:1.11 (1.06,1.17), PH: 0.92 (0.88, 0.97), TH: 1.17 (1.11, 1.23)], knowing someone who tested positive for COVID-19 [ID: 0.75 (0.65,0.88), MY: 0.82 (0.71,0.95), PH: 0.76 (0.67, 0.87), TH: 0.76 (0.59, 0.99), VN: 0.72 (0.54,0.97)], and perceived effectiveness of mask wearing [ID: 0.83 (0.74, 0.94), MY: 0.86 (0.79, 0.95), TH: 0.88 (0.8,0.98)]. Vaccine hesitancy is particularly strong among women in 3 countries—peaking at 52% in Indonesia, 42% in Malaysia, and 56% in the Philippines. Conclusion Results from the survey highlight the significance of a targeted vaccine education and research campaign. This study calls for streamlining of communications campaigns towards messages that promote vaccine uptake in the region, while better targeting those groups most vulnerable guided by the empirical findings herein.

Introduction: Ciguatera fish poisoning (CFP) is common in tropical and subtropical waters. On 13 November 2015, eight Filipino seafarers from a cargo ship sailing in the Caribbean Sea experienced a range of symptoms after consuming a barracuda. Upon their return to the Philippines, an investigation was conducted to describe the cases. Methods: A case-series was conducted. A CFP case was defined as a previously well individual on the ship who developed at least one gastrointestinal symptom and at least one neurologic manifestation after eating barracuda on 13 November 2015. All cases were admitted to hospital in Manila, Philippines and were interviewed using a standard questionnaire. Urine and serum samples of cases were collected for ciguatoxin (CTX) testing by radiological and receptor-binding assay. Results: Eight of the 25 seafarers on the ship ate the barracuda; all eight met the CFP case definition. The age of cases ranged from 37 to 58 years (median: 47 years) and all were males. Onset of symptoms ranged from 1 to 3 hours (median: 2 hours) from the time of ingestion of the barracuda. All cases experienced gastrointestinal (nausea, vomiting, diarrhoea) and neurologic (temperature allodynia, itchiness) symptoms but no cardiovascular manifestations. Urine and serum specimens of all eight cases showed CTX below the detection limit. Discussion The Philippines Epidemiology Bureau recommended that the Philippine Maritime Authority include CTX poisoning and its health risks in seafarers’ training to prevent future cases of CFP. The Event-based Surveillance and Response system will continue to provide a mechanism for the reporting and appropriate management of CFP cases.
