Monitoring of returnees from Ebola-affected areas: lessons learned based on the experience of French armed forces deployed in Guinea, 2015.

Introduction: During the 2014-15 Ebola virus disease (EVD) outbreak in West Africa, French armed forces were involved in the treatment and management of Ebola patients in Guinea. The constant flow of military personnel returning from their deployment posed a risk of secondary dissemination of the Ebola virus. Our objective was to describe the follow-up of returning service members that was implemented to prevent this risk of dissemination in France. Method: For the French military, a specific complementary follow-up was added to the national monitoring to take into account the need for a detailed record for follow-up of returning military personnel and to keep the military chain of command informed. Results: All the 410 service members deployed in Guinea underwent monitoring among whom 22 were suspected of EVD. Three of them were considered as possible EVD cases but none of them was tested positive for EVD. Conclusion: The monitoring organized for French service members deployed in Guinea made it possible to follow all exposed military personnel after their return, know their health status on a near real-time basis and be aware of all alerts. To reach this goal the collaboration with French national health agencies was necessary and should be improved in the future.

Etiology of Acute Febrile Illnesses in Adults in the Defense Community in French Guiana.

In tropical countries, acute febrile illnesses represent a complex clinical problem for general practitioners. We describe the prevalence of different etiologies of acute febrile illnesses occurring among French service members and their families, excluding children, in general practice in French Guiana. From June 2017 to March 2020, patients with a fever ≥37.8°C with a duration of less than 15 days who sought medical care at the army medical centers in Cayenne and Kourou were prospectively enrolled. Based on clinical presentation, blood, urine, nasopharyngeal, and stool samples were collected for diagnostic testing for viruses, bacteria, and parasites (by direct examination, microscopic examination of blood smears, culture, serology, or polymerase chain reaction), and standardized biological tests were systematically performed. Among 175 patients retained for analysis, fever with nonspecific symptoms was predominant (46.9%), with 10 Plasmodium vivax malaria cases, 8 dengue infections, and 6 cases of Q fever. The second most frequent cause of acute febrile illness was upper respiratory tract infections (32.0%) due to influenza virus (n = 18) or human rhinovirus (n = 10). Among the causes of acute febrile illness in French Guiana, clinicians should first consider arboviruses and malaria, as well as Q fever in cases of elevated C-reactive protein with nonspecific symptoms and influenza in cases of signs and symptoms associated with upper respiratory tract infections. Despite an expanded microbiological search, the etiology of 51.4% of acute febrile illnesses remain unknown. Further investigations will be necessary to identify the etiology of acute febrile illnesses, including new pathogens, in French Guiana.

Monkeypox clinical disease: Literature review and a tool proposal for the monitoring of cases and contacts.

The human monkeypox disease has mainly been described in Western and Central Africa. Since May 2022, the monkeypox virus has been spreading worldwide in a new epidemiological pattern, where cases result from person-to-person transmission, and develop clinically milder or less typical illness than during previous outbreaks in endemic areas. The newly-emerging monkeypox disease needs to be described over the long term, to improve cases definitions, to implement prompt control measures against epidemics, and to provide supportive care. Hence, we first conducted a review of historical and recent outbreaks to define the full clinical spectrum of the monkeypox disease and its course known so far. Then, we built a self-administrated questionnaire collecting daily symptoms of the monkeypox infection to follow cases and their contacts, even remotely. This tool will assist in the management of cases, the surveillance of contacts, and the conduct of clinical studies.

Public health investigation in a military cAMP after diagnosis of rabies in a dog-Afghanistan, 2012.

Rabies is one of the risks to which travelers are exposed when going abroad. During the summer of 2012, a rabid dog died in an International Military Transit Camp in Afghanistan, leading to a public health investigation briefly reported here. The lessons learned from this episode are that such investigations are complex and that information for travelers needs to be improved.
