Chikungunya infection in returned travellers: results from the geosentinel network, 2005-2020.

Background: Chikungunya is an important travel-related disease because of its rapid geographical expansion and potential for prolonged morbidity. Improved understanding of the epidemiology of travel-related chikungunya infections may influence prevention strategies including education and vaccination.

Methods: We analysed data from travellers with confirmed or probable chikungunya reported to GeoSentinel sites from 2005 to 2020.

Chikungunya Outbreak in Country with Multiple Vectorborne Diseases, Djibouti, 2019-2020.

During 2019-2020, a chikungunya outbreak occurred in Djibouti City, Djibouti, while dengue virus and malaria parasites were cocirculating. We used blotting paper to detect arbovirus emergence and confirm that it is a robust method for detecting and monitoring arbovirus outbreaks remotely.

Role and Limits of COVID-19 Vaccines in the Delicate Transition from Pandemic Mitigation to Endemic Control.

The recent surge of COVID-19 related to the Omicron variant emergence has thrown a harsh light upon epidemic control in the near future. This should lead the scientific and medical community to question the long-term vaccine strategy for SARS-CoV-2 control. We provide here a critical point of view regarding the virological evolution, epidemiological aspects, and immunological drivers for COVID-19 control, including a vaccination strategy.

Determinants of Health-Related Quality of Life in Chronic Chikungunya Disease in Guadeloupe.

Chronic chikungunya disease is associated with a poor quality of life and a variety of symptoms, not restricted to the musculoskeletal system. Patients with chronic chikungunya disease in Guadeloupe were evaluated in order to identify the main factors determining the quality of life. Patients were followed up at a mean of 36 months after chikungunya infection, undergoing detailed clinical examination for musculoskeletal involvement, with assessment of subjective symptoms and the impact on mood, physical activity, and quality of life (SF12).

Emergence of Indian lineage of ECSA chikungunya virus in Djibouti, 2019.

The chikungunya virus (CHIKV) originated from Africa and has spread worldwide. Since 2017, multiple chikungunya outbreaks have been reported in the Horn of Africa, without molecular characterization. In November 2019, an autochthonous acute chikungunya infection was diagnosed in a French patient living in Djibouti, marking the re-emergence of the virus in the country.

Incidence of leptospirosis in the French armed forces from 2004 to 2018: Retrospective analysis.

Background: The French military personnel may be exposed to leptospirosis during their training or on duty on the field in continental France, and most of all, in intertropical areas in the French departments and in Africa. The aim of this study was to assess the incidence of leptospirosis from epidemiological surveillance and cases data from 2004 to 2018, and to propose tools to assess leptospirosis risk prior to any mission or leisure activity.

Method: A retrospective epidemiological study on leptospirosis cases among French Armed Forces was conducted.

Update on the treatment of musculoskeletal manifestations in chikungunya fever: a guideline.

Since the emergence of the chikungunya virus in Brazil in 2014, more than 700,000 cases have been reported throughout the country, corresponding to one-third of all cases reported in the Americas. In addition to its high attack rates, resulting in hundreds of thousands of cases, the disease has high chronicity rates with persistent joint manifestations for more than 3 months, which can spread to more than half of the patients affected in the acute phase. Pain associated with musculoskeletal manifestations, often disabling, has an effect on patients' quality of life at different stages of the disease.

The challenging management of Rift Valley Fever in humans: literature review of the clinical disease and algorithm proposal.

Rift Valley Fever (RVF) is an emerging zoonotic arbovirus with a complex cycle of transmission that makes difficult the prediction of its expansion. Recent outbreaks outside Africa have led to rediscover the human disease but it remains poorly known. The wide spectrum of acute and delayed manifestations with potential unfavorable outcome much complicate the management of suspected cases and prediction of morbidity and mortality during an outbreak.

Clinical Features of Mycobacterium canettii Infection: A Retrospective Study of 20 Cases Among French Soldiers and Relatives.

Background: Mycobacterium canettii forms part of the Mycobacterium tuberculosis complex. Mycobacterium canettii infections are mainly described in the Horn of Africa. The permanent presence of French soldiers in Djibouti raises the question of the risk of being infected with M.

Evolution of symptoms and quality of life during Zika virus infection: A 1-year prospective cohort study.

Background: Although the complications of Zika virus infection have been well described, the clinical pattern has not been reported in enough detail to differentiate this infection from those with other arboviroses, and no longitudinal study has yet been published on the persistence of symptoms and quality of life.

Objectives: were to describe bio-clinical pattern and quality of life during ZIKV infection, and their evolution.

Study Design: We present a 1-year clinical follow-up of 49 people infected with Zika virus in French Guiana, for whom the diagnosis was confirmed by RT-PCR in serum or urine.

Surveillance of travel-associated diseases at two referral centres in Marseille, France: a 12-year survey.

Background: With increasing international travel and historically high numbers of residents visiting friends and relatives overseas, travel-associated illnesses are frequent in Marseille, France. We report the changing epidemiology of travel-related illnesses over a 12-year period.

Methods: A single site GeoSentinel surveillance analysis was undertaken for 3460 ill returned travellers presenting to two public hospitals in Marseille, France from March 2003 to October 2015, with travel-related illnesses.
