Frequently Asked Questions
What is an outbreak?
An outbreak is defined
as more cases of a disease than expected in a specific location over a specific time period. This can be a few cases or hundreds depending on the disease, time and location and population.
How does the military monitor these disease and illnesses?
Military surveillance data is primarily collected from the Disease Reporting Surveillance internet system, or DRSi, which military medical facilities must use to document all cases that meet military
Reportable Medical Event, or RME, criteria.
The military RMEs are specific medical conditions that must be reported to the military's DRSi system within 1 to 7 days for health surveillance purposes. The military's
current list of 71 RMEs includes the CDC’s “Notifiable Diseases"
which are priority public health concerns because they are known as
communicable diseases that are spread between people, from animals to people or from contact with surfaces or from food or water sources. The military RMEs also include non-communicable military-unique concerns such as heat- and cold weather-related injuries, and pediatric blood lead results.
RME cases are defined as
suspected,
probable, or
confirmed based on specified definition criteria that can include symptoms as well as laboratory data. RME clinical guidance ensures consistent reporting and helps local level contact-tracing efforts:

What happens when new diseases are identified?
Health surveillance and outbreak investigations can help with the identification of new or novel diseases not previously included in routine disease monitoring. For more details, see this DHA Factsheet: What is a Novel Respiratory Virus? (Sep 2024)
