In the history of human civilization, influenza is the second most catastrophic killer disease for mankind with plague ranking first in the medieval times. The 1918-1919 'Spanish flu' killed 20-50 million people worldwide. According to a report from WHO, there have been four pandemics, several epidemics and recurrent seasonal outbreaks of influenza in different parts of the world. The virus is a potential bioterrorism threat with biological 'Chernobyl-like disaster' that occurred in Soviet Russia in 1977. Here, the author reviews the biology of the surface exposed hemagglutinin of the influenza virus, a gene under constant positive selection pressure to evade host immunity and vaccination...

Mass casualty incidents (MCIs) are becoming more frequent worldwide, especially in the Middle East where violence in Syria has spilled over to many neighboring countries. Lebanon lacks a coordinated prehospital response system to deal with MCIs; therefore, hospital preparedness plans are essential to deal with the surge of casualties. This report describes our experience in dealing with an MCI involving a car bomb in an urban area of downtown Beirut, Lebanon. It uses general response principles to propose a simplified response model for hospitals to use during MCIs...

Natural disasters are on the increase. How healthcare systems respond to their communities' need for medical attention after such events will be very challenging. The situation is even more complicated when such facilities are forced to unexpectedly close and evacuate because they are in harm's way. There are important lessons to be learned from these events, yet people are slow to share what they experienced.

This study examined the mediating role of perceived severity of trauma and rumination in the relationship between traumatic experiences and PTSD, and assessed the moderated role of resilience in this mediating process. Nine hundred and fifty-one adolescents were selected to complete a self-report questionnaire involving rainstorm-related experiences, perceived severity of trauma, rumination, resilience, and PTSD. The results found that rainstorm-related experiences had a positive effect on PTSD by perceived severity of disaster, or by rumination via perceived severity of disaster...

Forensic anthropology makes an important contribution to human identification and assessment of the causes and mechanisms of death and body disposal in criminal and civil investigations, including those related to atrocity, disaster and trafficking victim identification. The methods used are comparative, relying on assignment of questioned material to categories observed in standard reference material of known attribution. Reference collections typically originate in Europe and North America, and are not necessarily representative of contemporary global populations...

OBJECTIVE: A series of sniper attacks in the Washington, DC, area left 10 people dead and 3 wounded. We developed and tested a model that examined the unique and interdependent relationships of sniper-related television viewing, prior life-threatening events, and parental status to identification with attack victims. METHODS: Participants were 1238 residents of the DC area (aged 18-90 years, mean=41.7 years; 51% female; 68% white) who completed an online survey that assessed identification with sniper attack victims, amount of television viewing, and prior life-threatening events...

OBJECTIVE: We investigated the extent of delays in the response time of emergency medical services (EMS) as an impact of mass casualty incidences (MCIs) in the same area. METHODS: We defined an MCI case as an event that resulted in 6 or more patients being transported by EMS, and prehospital response time as the time from the call to arrival at the scene. We matched patients before and after MCIs by dividing them into categories of 3 hours before, 0-1 hour after, 1-2 hours after, and 2-3 hours after the MCIs...

OBJECTIVES: Despite the frequency of disasters in Africa, almost nothing is known about ethnic affiliations in relation to psychopathology after such incidents. This study examined the mental health outcomes of members of 7 major ethnic groups exposed to the 1998 terrorist bombing of the US Embassy in Nairobi, Kenya. METHODS: Approximately 8 to 10 months after the disaster, 229 civilian employees, 99 locally engaged staff workers of the US State Department and the US Agency for International Development, and 64 workers of the Kenyan Red Cross Society (total N=392) were assessed with the Diagnostic Interview Schedule for the Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition)...

In recent years, the ecology, security, and sustainable development of modern mines have become the theme of coal mine development worldwide. However, spontaneous combustion of coal under conditions of oxygen supply and automatic exothermic heating during coal mining lead to coalfield fires. Coal spontaneous combustion (CSC) causes huge economic losses and casualties, with the toxic and harmful gases produced during coal combustion not only polluting the working environment, but also causing great damage to the ecological environment...

Large-scale forensic investigations may follow episodes of mass violence and disasters where hundreds or thousands of people have died or are missing. A number of unique challenges for forensic science, different from domestic investigations, arise in these contexts. The setting and situation of these investigations regularly force forensic scientists into practices not regularly encountered while working in a standard criminal justice system. These practices can entail activities not specific to a practitioner's particular field or necessarily be scientific in nature, but are still needed in order for the investigation to move forward...

INTRODUCTION: Medical Emergency Response Team (MERT) helicopters fly at altitudes of 3000 m in Afghanistan (9843 ft). Civilian hospitals and disaster-relief surgical teams may have to operate at such altitudes or even higher. Mild hypoxia has been seen to affect the performance of novel tasks at flight levels as low as 5000 ft. Aeromedical teams frequently work in unpressurized environments; it is important to understand the implications of this mild hypoxia and investigate whether supplementary oxygen systems are required for some or all of the team members...

BACKGROUND: Detailed assessments of mortality patterns, particularly age-specific mortality, represent a crucial input that enables health systems to target interventions to specific populations. Understanding how all-cause mortality has changed with respect to development status can identify exemplars for best practice. To accomplish this, the Global Burden of Diseases, Injuries, and Risk Factors Study 2016 (GBD 2016) estimated age-specific and sex-specific all-cause mortality between 1970 and 2016 for 195 countries and territories and at the subnational level for the five countries with a population greater than 200 million in 2016...

Disasters in countries with limited resources can put the emergency preparedness of the country to the test. The first major task after a disaster is to take care of the wounded. In countries where the epidemiological transition has occurred, chronic disease can place a major strain on public health preparedness after a disaster. The purpose of this field report is to alert public health practitioners of an infrequently reported public health problem: the impact of natural disasters on adherence to chronic medications...

OBJECTIVES: To determine whether, during a hurricane, geographic accessibility to hospitals with emergency care is compromised disproportionately for the elderly than for the nonelderly. METHODS: The locations of hospitals with emergency health care and a subset of those hospitals functional during a hurricane were compared with the distribution of the elderly population at the block group level in Palm Beach County, Florida. Geographic Information Systems (GIS) proximity analysis (minimum distance to closest hospital) and cumulative distribution functions were used to measure and compare hospital accessibility during normal and hurricane conditions for the elderly and nonelderly populations...

Two studies, with a total of 707 participants, developed and examined the reliability and validity of a measure for anticipatory traumatic reaction (ATR), a novel construct describing a form of distress that may occur in response to threat-related media reports and discussions. Exploratory and confirmatory factor analysis resulted in a scale comprising three subscales: feelings related to future threat; preparatory thoughts and actions; and disruption to daily activities. Internal consistency was .93 for the overall ATR scale...

This study draws upon interviews of medical staff working in the city of Minamisoma, Japan, following the 2011 Triple Disaster. It investigates staff responses to the disruption of material resources as a consequence of the disaster and its management. The disruption of spaces, and the loss of oxygen supplies, food, and medications impacted upon staff experience and the ability of institutions to care for patients. This resulted in a restructuring of spaces and materials as workers made efforts to reconfigure and reestablish healthcare functions...
