Army Maj. Jareè Lenore Johnson, Entomology Chief, U.S. Army Medical Research Directorate-Africa, is a board-certified entomologist with the Walter Reed Army Institute of Research (WRAIR). She is currently stationed in Kisumu, Kenya and studies insects and pests in order to monitor their behavior and patterns to prevent diseases among the military population.

What vector-borne projects are you working on?

Insecticide resistance, arthropod vectors and their diseases, insecticidal product/spatial testing, and tracking vertebrate ectoparasites and their associated diseases

Army Maj. Jareè Lenore Johnson, entomology chief at the U.S. Army Medical Research Directorate-Africa, speaks with students at the International School in Kenya on harmful and beneficial arthropods. 

What led you to this career?

I was fascinated by critters (animals and insects) at a young age. In college, I started out in animal science because I wanted to be a veterinarian, but fell in love with entomology after accepting a research fellowship to work with ticks/Lyme disease in dogs and humans. Around this time, West Nile Virus entered the East Coast and I had the opportunity to conduct mosquito surveillance for the first time—it was fun! I have two master’s degrees in Animal Health and Diseases and Medical Entomology.

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

The ability to work with various medically important arthropods and vertebrate pest. The military has given me the opportunity to travel and surround myself with various cultures. There are always new scientific discoveries and I am constantly reading scientific literature to ensure that I am up-to-date on the latest news in medical-veterinary entomology. I am constantly challenged to learn what I don’t know, and that has made me successful in my craft.

Have you contributed to any interesting projects?

I was selected to stand up the Army Public Health Center's first insecticidal resistance program. This grassroots project allowed my soldiers to work on local entomology issues that were not conducted on other installations or Army PM field. This work was rewarding because I was able to teach others and bring a much needed capability to the organization.

Human Physiologic Responses to Cold Exposure

Infographic
1/9/2017
Human Physiologic responses to cold exposure preserve core body temperature, but those responses may not be sufficient to prevent hypothermia if heat loss is prolonged. This infographic offers helpful information on preserving core body temperature to counter the threat from cold environments. Physiologic responses include: •	Constriction of the peripheral (superficial) vascular system – may result in non-freezing injuries or hasten the onset of actual freezing of tissues (frostbite) •	Minimizing loss of body heat •	Protecting superficial tissues Protection includes:	 •	Nutrition •	Shelter •	Physical Activity •	Protective Clothing Learn more about preserving core body temperature by reading the Medical Surveillance Monthly Report at www.Health.mil/AFHSB

Rift Valley Fever Virus Ecology

Infographic
12/5/2016
This infographic describes Rift Valley Fever (RVF) virus ecology and how RVF infects livestock and humans.   •	First the enzootic cycle begins. It is maintained via transfer from parent mosquito to offspring. This is a local, low-level transfer of disease to livestock and happens during periods of average rainfall. •	Next, high rainfall and flooding enable Aedes mosquito breeding environments to flourish. This is followed by epizootic outbreaks, which cause abortion storms in animals, with > 90% mortality in newborns and 10-20% mortality in adults. Secondary vectors, including other mosquito genera such as Culex, can pass on the virus to humans and animals.  Spillover to humans includes exposure to blood and tissue of infected livestock and occurs during slaughter or birthing activities. Humans can also be infected with RVF via bites of infected mosquitos.

Preserving the Health of U.S. Armed Forces with DMSS and DoDSR

Infographic
7/13/2016
The Defense Medical Surveillance System (DMSS) and the DoD Serum Repository (DoDSR) provide unprecedented capabilities for conducting comprehensive population-based surveillance of the U.S. Armed Forces while protecting the privacy and confidentiality of service members. The systems together provide glimpses of the capabilities and potential uses of public health surveillance systems of the future.  The research advantages of the DMSS and DoDSR The DMSS and DoDSR enable researchers to focus time and attention on solving methodological problems, interpreting results, producing summaries and reports.  DMSS includes personnel data, medical data, laboratory data, deployment data, and DoDSR data. Benefactors of the DMSS and DoDSR are epidemiologists, preventive medicine doctors, data analysts, DoD policy makers, Military Commanders and public health officers. Learn how to harness the full value of the DMSS and DoDSR at www.Health.mil/AFHSB

HIV and AIDS in the U.S. Military

Infographic
6/27/2016
June 27th is National HIV Testing Day. HIV-1 infection is a major health importance for the U.S. military. Since the start of HIV-1 military health surveillance analysis during 1990-2013, service members diagnosed with the HIV-1 infection in recent years have remained longer in U.S. Armed Forces.  There were a total of 5,227 new diagnoses in 24-years of surveillance. The August 2015 Medical Surveillance Monthly Report (MSMR) reported that “Estimated median durations of service after initial HIV-1 diagnoses ranged from 2.29 years in Cohort 1 ( 1990-1994) to 3.65 years in Cohort 4 (2005-2009). Thus, in the 15 years between 1990-1994 and 2005-2009, the median durations of service after HIV-1 diagnoses increased by 1.4 years.” Factors contributing to longer service include: •	Availability and effectiveness of HIV treatments •	Decline in stigmas associated with diagnosis of the HIV infection •	Changes in U.S. military policy that allow the LGBT community to serve in its ranks  Note: Service members who are diagnosed with HIV-1 infections, regardless of their sexual orientations, may elect to continue their military service careers.  Get tested today – it’s the only way to know. Early HIV testing helps to prevent transmission and lowers the risk of severe health complications.

The HPV Vaccine Saves Lives

Infographic
5/16/2016
The Defense Department recommends male and female military service members, ages 17-26 years, receive an HPV vaccine series to generate a robust immune response to the quadrivalent human papillomavirus vaccine (HPV4). This graphic highlights information the benefits of the HPV vaccine. The vaccine is most effective among fully vaccinated individuals.   Cancer Prevention Facts •	HPV is the most common sexually  transmitted infection (STI) •	There are more than 40 HPV types that can infect the genital areas •	Some HPV types give warts •	Some HPV types develop cancer  Effective Against STI Transmission •	The HPV vaccine is a safe and effective way to protect yourself from the virus •	The HPV vaccine provides nearly 100% protection from HPV types 6,11,16 and 18 •	HPV vaccine shows early signs of success in reducing HPV infections and related illnesses •	Protection is expected to be long-lasting  Safety Tips •	Getting your HPV vaccine and practicing safe sex such as wearing a condom may lower the risk of HPV •	Limiting the number of lifetime sex partners can also lower the risk of HPV •	When given the HPV vaccine, the body makes antibodies in response to the protection to clear it from the body  Get the Facts •	2,091 female service members aged 17-26 years received 1-3 HPV4 doses during 2006-2012, stratified by number of doses (1, 2, or 3).  Get the HPV Vaccine •	Only 22.5% of eligible service members initiated the series •	Of those, only 39.1% completed the full three-dose series as of June 2011.  Even though the 3 dose regiment provides nearly complete protection against HPV16 and HPV18, in the U.S., only 12% and 19% of female adolescents among commercial and Medicaid plans respectively complete the series.
