A Q & A with Dr. Jose L. (Toti) Sanchez, Senior Scientist & Deputy Chief, AFHSB


What is your focus area?

A major component of my work is to ensure that major health surveillance program plans and initiatives are current and reflect alignment with the Defense Health Agency’s Strategic Plan. Under the guidance of AFHSB’s Chief, I also help to build strong scientific and collaborative relationships within the Public Health Directorate.

How do you monitor disease outbreaks?

I spend a significant amount of time monitoring the many peer-reviewed, governmental and international association reports. I also analyze the disease outbreak reports and coordinate data gathering and report generation from AFHSB’s Global Emerging Infections Surveillance, Epidemiology and Analysis), and Integrated Biosurveillance  sections.

In my role as Senior Scientist at AFHSB, I serve on the Infectious Disease Clinical Research Program Operational Steering Committee, a “think-tank” committee of experts who provide guidance on military-relevant research efforts in support of the U.S. military’s force health protection needs. I also work as an instructor at the Uniformed Services University of the Health Sciences. I ensure students and residents in public health learn the basic skills of outbreak investigation, associated surveillance, and research initiatives.

How do you support AFHSB's response to COVID-19?

The COVID-19 pandemic has placed an immense workload on our AFHSB staff to produce analyses and reports for DHA leadership, senior DoD officials, the Secretary of Defense, and respond to questions from Congressional officials. In my role as Deputy Chief, AFHSB, I ensure that reports, documents and COVID-19 related policy reviews are accurate and produced in a timely fashion from AFHSB’s three sections. Since February 2020, I’ve reviewed and provided input to nearly 70 executive summaries , several information and position papers, and at least 20 weekly surveillance summaries addressing COVID-19 issues.

Where have you traveled in this role?

My travel is mainly limited to the National Capital Region. I’ve participated in tabletop drills such as an interagency simulation for Crimson Contagion, a response to a severe influenza pandemic. I’ve also served as a representative to the Defense Health Board to evaluate health surveillance matters such as COVID-19 and respiratory infections in support of DHA’s Combat Support Agency mission.

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).

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).

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.

Contraception among active component service women, U.S. Armed Forces, 2012 – 2016

Infographic
1/5/2018
Because the majority of women serving in the Armed Forces are of childbearing age, and women’s military career opportunities have expanded into combat roles, contraceptive health care is an increasingly important public health issue. The lack of available, population-based descriptive information on contraceptive use among U.S. service women has generated questions and concerns about ready access to these medical products. This infographic summarizes the annual prevalence of permanent sterilization, as well as use of long – and short-acting reversible contraceptives (LARCs and SARCs, respectively), contraceptive counseling services, and use of emergency contraception from 2012 through 2016, among active component service women. FINDINGS •	2012 through 2016, Sterilization decreased from 4.2% to 3.6% LARC use increased from 17.2% to 21.7%; SARC use decreased from 38.5% to 30.4%. •	Emergency contraception use increased from 0.4% to 1.9%. •	Among deployed women, the average annual prevalence of permanent sterilization was 4.2%. •	For deployed women, LARC use was 17.9% SARC use was 28.0%. •	Emergency contraception use among deployed women was 0.4%. •	262,907 (76.2%) women of childbearing potential (WOCBP) used either a LARC or a SARC at some time during the surveillance period. •	The vast majority of service women have utilized at least one form of contraception, and women are selecting LARCs in greater numbers with each passing year.
