During a COVID-19 outbreak on the Diamond Princess cruise ship we sampled environmental surfaces after passengers and crew vacated cabins. SARS-CoV-2 RNA was detected in 58 of 601 samples (10%) from case cabins 1-17 days were but not noncase There no difference detection proportion between symptomatic (15%, 28/189; cycle quantification [Cq], 29.79-38.86) asymptomatic cases (21%, 28/131; Cq, 26.21-38.99). No virus isolated any samples. Transmission risk patients may be similar could involved...
Objective: Overdose Fatality Review (OFR) is a public health process in which cases of fatal overdose are carefully reviewed to identify prevention strategies. Current OFR requires review multiple unconnected data sources, manually intensive process. We aimed use human factors design principles develop comprehensive dashboard that could facilitate enhanced processes support OFR. Materials and Methods: first surveyed leaders Wisconsin using the NASA Task Load Index (NASA-TLX) conducted...
ABSTRACT Human infections with influenza A(H5N1) virus in Cambodia increased sharply during 2013. Molecular characterization of viruses detected clinical specimens from human cases revealed the presence mutations associated alteration receptor-binding specificity (K189R, Q222L) and respiratory droplet transmission ferrets (N220K Q222L). Discovery quasispecies at position 222 (Q/L), addition to absence poultry/environmental samples, suggested that occurred infection did not transmit further.
Summary Background A COVID-19 outbreak occurred in a cruise ship with 3711 passengers and crew 2020. This study is to test the hypothesis that environmental surfaces played important roles transmission for SARS-CoV-2 during this outbreak. Methods We sampled including air from common areas cabins which confirmed cases non-cases had stayed after they left cabins. tested samples by rt-PCR conducted viral isolation. Findings Of 601 tested, RNA was detected 58 (10%) case-cabins 1-17 days before...
Abstract Background Rapid and effective emergency response to address health security relies on a competent suitably trained local international workforce.

Improving the epidemiological response to emergencies requires an understanding of who responders are, their role and skills, challenges they face during responses. In this paper, we explore epidemiologist identify emergency response.We conducted a cross-sectional survey learn more about epidemiologists respond public health emergencies. The online included open closed-ended questions on faced while responding, roles epidemiology responders, self-rating support needed received. We used...
Abstract Background Influenza virus circulation is monitored through the Cambodian influenza‐like illness (ILI) sentinel surveillance system and isolates are characterized by National Centre (NIC). Seasonal influenza has previously been year‐round activity a peak during rainy season (June‐November). Objectives We documented of seasonal in Cambodia for 2012‐2015 investigated genetic, antigenic, antiviral resistance characteristics isolates. Patients/Methods Respiratory samples were collected...
The COVID-19 pandemic challenged the Global Outbreak Alert and Response Network's (GOARN) mechanism used to rapidly deploy technical support for international responses highlighted areas that require strengthened capacity within Network. GOARN's partners in World Health Organization's (WHO) South-East Asia Western Pacific regions were engaged explore their levels of preparedness, readiness ability respond public health emergencies.
Abstract Thirty-five human influenza A(H5N1) cases were reported in Cambodia during 2013–2014 after emergence of a clade 1.1.2 reassortant virus. We tested 881 villagers and found 2 pauci- or asymptomatic infection. Seroprevalence the strain (0.2%) was lower than aggregate seroprevalence 1.3% earlier studies.
Introduction Determinants and drivers for emergencies, such as political instability, weak health systems, climate change forcibly displaced populations, are increasing the severity, complexity frequency of public emergencies. As emergencies become more complex, it is increasingly important that required skillset emergency response workforce clearly defined. To enable essential epidemiological activities to be implemented managed during an emergency, a with right mix skills, knowledge,...
Healthcare workers (HCWs) are at an increased risk of TB worldwide. Individual knowledge and attitudes may influence HCW behaviour, subsequently, risk. Indonesia has the second highest case-load globally.
Enteric fever is a systemic bacterial infection in humans that endemic Cambodia and for which antibiotic resistance increasingly reported. To guide public health programs, this qualitative study sought to explore community perceptions on transmission treatment. Participant observation was carried out hospital settings, pharmacies, at level Phnom Penh. In-depth interviews 39 one focus group discussion were with blood culture–confirmed enteric patients purposively selected key informants....
Childcare centres can be high-risk settings for SARS-CoV-2 transmission due to age, vaccination status, and infection control challenges. We describe the epidemiology clinical characteristics of a childcare Delta outbreak. When outbreak occurred, little was known about dynamics ancestral strains among children.
