As an organization that receives countless streams of data and information, the staff at the Armed Forces Health Surveillance Branch (AFHSB) knows quite a bit about the global threats posed by known and emerging infectious diseases of military relevance. Today, AFHSB’s Integrated Biosurveillance (IB) Section is taking revolutionary steps to produce even more relevant, user-driven health surveillance products that enable its customers, especially the U.S. Combatant Commands, to focus on what they need to know to provide a medically ready military force in peace and wartime.

Interactive surveillance maps created by the Armed Forces Health Surveillance Branch show the global threats posed by endemic and emerging infectious diseases that help Combatant Commands provide a medically ready military force.Interactive surveillance maps created by the Armed Forces Health Surveillance Branch show the global threats posed by endemic and emerging infectious diseases that help Combatant Commands provide a medically ready military force.

 

AFHSB recently released new, web-based interactive disease surveillance maps that allow Combatant Commanders to zoom to an area of interest, click on individual points, and extract exactly what they need to know about a particular disease event. The accompanying text can contain relevant links, sources, and images in their native, high resolution format. With the click of a button, an analyst can instantly upload data from his or her terminal in Washington, D.C., for a decision-maker stationed in Germany, with information that is specifically tailored for that organization’s needs.

As part of the Defense Health Agency’s role as a combat support agency, “it is vital for AFHSB to provide timely health surveillance information to the Combatant Commands with the appropriate flexibility and agility required to support Force Health Protection decisions,” said Mr. Juan Ubiera, chief of the IB section. “These dynamic products provide Department of Defense leaders with a large amount of information in a manner that supports both rapid operational decisions and a deeper understanding of what's going on.”

AFHSB’s latest product in this gallery is The Avian Influenza Epidemic. This product leverages data from near real-time disease reporting systems along with geocoding capabilities to present an emerging picture of the avian influenza A (AI) virus subtypes currently affecting avian populations globally. An overlay of the global flight paths of the wild birds that carry AI viruses enables the viewer to connect outbreaks of particular AI subtypes to the migratory routes that may have facilitated their introduction. This product also depicts human cases of infection with novel and variant influenza A viruses, conveying Defense Department relevance of these occurrences through an in-house designed infographic, all within a dynamic environment.

This new release joins other products in the IB interactive gallery such as The MERS-CoV Epidemic, an interactive surveillance product that guides the user through the Middle East respiratory syndrome coronavirus (MERS-CoV) epidemic in a new and captivating format. Users will also find surveillance products on the 2014 Ebola outbreak in West Africa and the emergence of the Chikungunya virus in the Americas.

To create these visualizations, AFHSB is implementing leading-edge, commercial-off-the-shelf tools designed by Esri, a geospatial service provider. Our analysts are able to standardize and edit data directly from their desktops; with a few keystrokes, the data are sent to the cloud, instantly updating our products with the latest information. This represents a major leap forward from AFHSB’s current email-based distribution system.

“This type of product and [the] attractive and easy to read visuals are very useful for the education of leadership and others in our division on the importance of avian influenza,” Dr. Jennifer Steele, the Infectious Disease Subject Matter Expert for U.S. European Command after previewing The Avian Influenza Epidemic product. “The maps and graphics help explain why [avian influenza] elsewhere in the world and in other species is important from a human health and operational perspective.”

Surveillance for Vector-Borne Diseases, Active and Reserve Component Service Members, U.S. Armed Forces, 2010 – 2016

Infographic
2/14/2018
Within the U.S. Armed Forces considerable effort has been applied to the prevention and treatment of vector-borne diseases. A key component of that effort has been the surveillance of vector-borne diseases to inform the steps needed to identify where and when threats exist and to evaluate the impact of preventive measures. This report summarizes available health records information about the occurrence of vector-borne infectious diseases among members of the U.S. Armed Forces, during a recent 7-year surveillance period. For the 7-surveillance period, there were 1,436 confirmed cases of vector-borne diseases, 536 possible cases, and 8,667 suspected cases among service members of the active and reserve components. •	“Confirmed” case = confirmed reportable medical event. •	“Possible” case = hospitalization with a diagnosis for a vector-borne disease. •	“Suspected” case = either a non-confirmed reportable medical event or an outpatient medical encounter with a diagnosis of a vector-borne disease. Lyme disease (n=721) and malaria (n=346) were the most common diagnoses among confirmed and possible cases. •	In 2015, the annual numbers of confirmed case of Lyme disease were the fewest reported during the surveillance period. •	Diagnoses of Chikungunya (CHIK) and Zika (ZIKV) were elevated in the years following their respective entries into the Western Hemisphere: CHIK (2014 and 2015); ZIKV (2016). The available data reinforce the need for continued emphasis on the multidisciplinary preventive measures necessary to counter the ever-present threat of vector-borne disease.

Malaria U.S. Armed Forces, 2017

Infographic
2/14/2018
Since 1999, the Medical Surveillance Monthly Report (MSMR) has published periodic updates on the incidence of malaria among U.S. service members. Malaria infection remains an important health threat to U.S. service members, who are located in endemic areas because of long-term duty assignments, participation in shorter-term contingency operations, or personal travel. This update for 2017 describes the epidemiologic patterns of malaria incidence in active and reserve component service members of the U.S. Armed Forces. Findings •	A total of 32 service members were diagnosed with or reported to have malaria, which is the lowest number of cases in any given year during the 10-year surveillance period. •	Health records documented the performance of laboratory tests for malaria for 22 of the cases. The tests for 17 of the 22 were positive for malaria ( stick figure graphic visually depicts this information). •	In 2017, 75.0% (24 of 32) of malaria cases among U.S. service members were diagnosed during May – October (calendar graphic showing the months visually). •	Of the 32 malaria cases in 2017, more than 1/3 of the infections were considered to have been acquired in Africa. Two bar charts display the following information: •	Bar chart 1: Numbers of malaria cases by Plasmodium species and calendar year of diagnosis/report, active and reserve components, U.S. Armed Forces, 2008 – 2017  •	Bar chart 2: Annual numbers of cases of malaria associated with specific locations of acquisition, active and reserve components, U.S. Armed Forces, 2008 – 2017  The majority of U.S. military members diagnosed with malaria in 2017 were: •	Male (96.9%) •	Active component (81.3%) •	In the Army (75.0%) •	In their 20’s (56.3%) Access the full report in the February 2018 MSMR (Vol. 25 No. 2).

Seizures among Active Component service members, U.S. Armed Forces, 2007 – 2016

Infographic
1/25/2018
This retrospective study estimated the rates of seizures diagnosed among deployed and non-deployed service members to identify factors associated with seizures and determine if seizure rates differed in deployment settings. It also attempted to evaluate the associations between seizures, traumatic brain injury (TBI), and post-traumatic stress disorder (PTSD) by assessing correlations between the incidence rates of seizures and prior diagnoses of TBI and PTSD. Seizures have been defined as paroxysmal neurologic episodes caused by abnormal neuronal activity in the brain. Approximately one in 10 individuals will experience a seizure in their lifetime. Line graph 1: Annual crude incidence rates of seizures among non-deployed service members, active component, U.S. Armed Forces data •	A total of 16,257 seizure events of all types were identified among non-deployed service members during the 10-year surveillance period. •	The overall incidence rate was 12.9 seizures per 10,000 person-years (p-yrs.) •	There was a decrease in the rate of seizures diagnosed in the active component of the military during the 10-year period. Rates reached their lowest point in 2015 – 9.0 seizures per 10,000 p-yrs. •	Annual rates were markedly higher among service members with recent PTSD and TBI diagnoses, and among those with prior seizure diagnoses. Line graph 2: Annual crude incidence rates of seizures by traumatic brain injury (TBI) and recent post-traumatic stress disorder (PTSD) diagnosis among non-deployed active component service members, U.S. Armed Forces •	For service members who had received both TBI and PTSD diagnoses, seizure rates among the deployed and the non-deployed were two and three times the rates among those with only one of those diagnoses, respectively. •	Rates of seizures tended to be higher among service members who were: in the Army or Marine Corps, Female, African American, Younger than age 30, Veterans of no more than one previous deployment, and in the occupations of combat arms, armor, or healthcare Line graph 3: Annual crude incidence rates of seizures diagnosed among service members deployed to Operation Enduring Freedom, Operation Iraqi Freedom, or Operation New Dawn, U.S. Armed Forces, 2008 – 2016  •	A total of 814 cases of seizures were identified during deployment to operations in Iraq and Afghanistan during the 9-year surveillance period (2008 – 2016). •	For deployed service members, the overall incidence rate was 9.1 seizures per 10,000 p-yrs. •	Having either a TBI or recent PTSD diagnosis alone was associated with a 3-to 4-fold increase in the rate of seizures. •	Only 19 cases of seizures were diagnosed among deployed individuals with a recent PTSD diagnosis during the 9-year surveillance period. •	Overall incidence rates among deployed service members were highest for those in the Army, females, those younger than age 25, junior enlisted, and in healthcare occupations.

Insomnia and motor vehicle accident-related injuries, Active Component, U.S. Armed Forces, 2007 – 2016

Infographic
1/25/2018
Insomnia is the most common sleep disorder in adults and its incidence in the U.S. Armed Forces is increasing. A potential consequence of inadequate sleep is increased risk of motor vehicle accidents (MVAs). MVAs are the leading cause of peacetime deaths and a major cause of non-fatal injuries in the U.S. military members. To examine the relationship between insomnia and motor vehicle accident-related injuries (MVAs) in the U.S. military, this retrospective cohort study compared 2007 – 2016 incidence rates of MVA-related injuries between service members with diagnosed insomnia and service members without a diagnosis of insomnia. After adjustment for multiple covariates, during 2007 – 2016, active component service members with insomnia had more than double the rate of MVA-related injuries, compared to service members without insomnia. Findings:  •	Line graph shows the annual rates of motor vehicle accident-related injuries, active component service members with and without diagnoses of insomnia, U.S. Armed Forces, 2007 – 2016  •	Annual rates of MVA-related injuries were highest in the insomnia cohort in 2007 and 2008, and lowest in 2016 •	There were 5,587 cases of MVA-related injuries in the two cohorts during the surveillance period. •	Pie chart displays the following data: 1,738 (31.1%) in the unexposed cohort and 3,849 (68.9%) in the insomnia cohort The highest overall crude rates of MVA-related injuries were seen in service members who were: •	Less than 25 years old •	Junior enlisted rank/grade •	Armor/transport occupation •	 •	With a history of mental health diagnosis •	With a history of alcohol-related disorders Access the full report in the December 2017 (Vol. 24, No. 12).
