Bug-Borne Illnesses | Armed Forces Health Surveillance Branch

Navy Lt. Jodi Fiorenzano is a Navy entomologist stationed in Sembawang, Singapore where her team conducts vector surveillance throughout the Pacific to better understand regional diseases and help to prevent diseases outbreaks in the military population.

What vector-borne (mosquitoes, ticks, and fleas) projects are you working on?

My team and I conduct vector surveillance throughout the Pacific to better understand regional diseases, host and vector relations, and vector behaviors. In Cambodia, my team researches Dengue vectors and surveillance techniques in urban environments. We also research ectoparasites (fleas, lice, ticks, mites) and their diseases, along with sand flies and their related pathogens. In Laos and Mongolia, we conduct ectoparasites surveillance and study mosquito behaviors where both Malaria and Dengue reside in Vietnam. 

What do you enjoy most about entomology in the U.S. military?

I’ve met amazing entomologists from all the military services and worked alongside many partner nation and civilian entomologists and technicians. 

What are some of your most interesting projects? 

During my six years as a Navy Entomologist I was stationed in Hawaii and Singapore. I’ve taught integrated vector management techniques to multiple hospital corpsmen and participated in a vector management training program in Fiji, with the World Health Organization. I also helped plan Global Health Engagements with the Pacific Partnership in Sri Lanka, Malaysia and conducted Dengue Vector Threat assessments in Chuuk (one of four states in the Federated States of Micronesia), and East Timor to mitigate dengue risks to Navy construction teams. Most recently, I conducted regional surveillance throughout the Pacific to study multiple vectors (mosquitoes, ectoparasites, and sand flies) to understand vectors and their pathogens and add to the growing entomological knowledge across the DoD.

Routine Screening for Antibodies to Human Immunodeficiency Virus

Infographic
3/17/2017
The Human immunodeficiency virus type 1 (HIV-1) is the cause of Acquired immune deficiency syndrome (AIDS) and has had major impacts on the health of populations and on healthcare systems worldwide. This infographic provides an update on routine screening for antibodies to HIV among civilian applicants for the U.S. military service and U.S. Armed Forces during a January 2011 - June 2016 surveillance period.  Since October 1985, the U.S. military has conducted routine screening for antibodies to HIV-1 to enable adequate and timely medical evaluations, treatment and counseling; to prevent unwitting transmission; and protect the battlefield blood supply. From January 2015 through June 2016, 463,132 civilian applicants for U.S. military service were tested. 124 were identified as HIV antibody positive. During 2015, one was detected with antibodies to HIV per 3,267 screening tests. Annual seroprevalences peaked in 2015, up 29% from 2014. The seroprevalences were much higher among males than females and among black, non-Hispanics than other race/ethnicity groups. Seroprevalences decreased by approximately 26% among male applicants, dropped to zero among female applicants, and decreased by 43% among black, non-Hispanic applicants.  As for the active component of the U.S. Army, 548,974 soldiers were tested from January 2015 through June 2016. 120 were identified as HIV antibody positive. During 2015, one was detected with antibodies to HIV per 5,265 screening tests. Of the 515 active component soldiers diagnosed with HIV infections since 2011, a total of 291 (57%) were still in military service in 2016. Annual seroprevalences for male active component Army members greatly exceed those of females.  Among active and reserve component service members, seroprevalences continue to be higher among Army and Navy members and males than their respective counterparts. Service members who are infected with HIV receive clinical assessments, treatments, and counseling; they may remain in service as long as they are capable of performing their military duties.

5 Major Categories of Abdominal Hernia

Infographic
3/17/2017
An abdominal hernia is an abnormal protrusion of an organ or tissue through a defect in the abdominal wall. This infographic provides information on incident diagnoses of the five types of abdominal hernia that were documented in health records of 72,404 active component service members from 1 January 2005 through 31 December 2014.  A total of 87,480 incident diagnoses of the five types of abdominal hernia were documented in health records of 72,404 active component service members. Here are highlights of the findings from this study: •	The give types of abdominal hernia categories used in this analysis were: inguinal, umbilical ventral/ incisional, femoral and “other.” •	 During the 10-year interval, incidence rates for most of the five types of hernia trended downward but increased for umbilical hernias in both males and females and ventral/ incisional hernias among females. •	Overall incidence rate of inguinal hernias among males was six times the rate among females. •	Incidence rates of femoral, ventral/ incisional and umbilical hernias were higher among females than males. •	For most types of hernia incidence rates tend to be higher among older age groups.  Abdominal hernias are diagnosed most frequently in the inguinal, umbilical, and femoral regions, but another category of relatively common hernias of the anterior abdominal wall includes ventral and incisional hernias. Health records contained documentation for 35,624 surgical procedures whose description corresponded to the types of hernia diagnoses in U.S. military service members.
