Social media as Twitter are used today by people to disseminate health information but also to share or exchange on their health. Based on this observation, recent studies showed that Twitter data can be used to monitor trends of infectious diseases such as influenza. These studies were mainly carried out in United States where Twitter is very popular1-4. In our knowledge, no research has been implemented in France to know whether Twitter data can be a complementary data source to monitor seasonal influenza epidemic.

Objective: To investigate whether Twitter data can be used as a proxy for the surveillance of the seasonal influenza epidemic in France and at the regional level.

In Reunion Island, a French overseas territory located in the southwestern of Indian Ocean, the dengue virus circulation is sporadic. Since 2004, between 10 and 221 probable and confirmed autochthonous dengue fever cases have been reported annually. Since January 2018, the island has experienced a large epidemic of DENV serotype 2. As of 4 September 2018, 6,538 confirmed and probable autochthonous cases have been notified1. From the beginning of the epidemic, the regional office of National Public Health Agency (ANSP) in Indian Ocean enhanced the syndromic surveillance system in order to monitor the outbreak and to provide hospital morbidity data to public health authorities.

Objective: To describe the characteristics of ED vitis related to dengue fever and to show how the syndromic surveillance system can be flexible for the monitoring of this outbreak.

In Reunion Island, alcohol is the most experienced psychoactive substance [1]. Alcohol consumption is characterized by a massive ingestion of hard liquor and an early experimentation. Health consequences are significant: a high annual incidence of fetal alcohol syndromes [2] and a higher premature mortality than in France mainland [1]. Reunion island is one the French regions most affected by addictive behaviors related to alcohol. However, existing data are insufficient concerning the current health impact and associated factors.

Objective

Describe the emergency departments' visits for alcohol intoxication (AI) in Reunion Island and factors associated with their variations.

The 'Grand Raid de la Reunion' is one of the hardest ultra trails in the world (5,350 competitors in 2012). This one stage race takes place in Reunion Island, a French overseas department in the Indian Ocean. Ultra trails and ultra marathons are intense long-distance running races pushing back human physical abilities' limits. In general terms, studies about these races highlight different severity levels' injuries, from asymptomatic to critical condition [1-4]. No study has yet used syndromic surveillance to study the impact of such sporting events on ED visits. Using a syndromic surveillance approach to monitor sport-related visits could allow an early public health response.

Objective

To estimate the health impact of the 'Grand Raid de la Reunion' (GRR) ultra trail in 2012 on the emergency departments (ED) of Reunion Island.

In Reunion Island, the non-specific surveillance was mainly developed during A(H1N1) influenza pandemic in 2009. In March 2010, a new surveillance system was implemented from National Health Insurance data. This monitoring was based on the weekly consultation number and home visits by general practitioners.

 

Objective

To assess the ability to detect an unusual health event from National Health Insurance data.

Description

In Reunion Island, the non-specific surveillance was developed since 2006 and was based on the activity of only one hospital emergency department and on mortality. To respond to the threat of influenza A(H1N1) pandemic emergence, this surveillance system was significantly enhanced. All hospital emergency departments of the island have been included as well as the emergency medical service regulation center. In 2010, a new surveillance was implemented from National Health Insurance data.

 

Objective

To demonstrate that the different surveillance systems allow to establish complementary indicators.

Description

The late health events such as the heat wave of 2003 showed the need to make public health surveillance evolve in France. Thus, the French Institute for Public Health Surveillance has developed syndromic surveillance systems based on several information sources such as emergency departments. In Reunion Island, the chikungunya outbreak of 2005-2006, then the influenza pandemic of 2009 contributed to the implementation and the development of this surveillance system. In the past years, this tool allowed to follow and measure the impact of seasonal epidemics. Nevertheless, its usefulness for the detection of minor unusual events had yet to be demonstrated.

 

Objective

To show with examples that syndromic surveillance system can be a reactive tool for public health surveillance.

Mayotte Island, a French overseas department of around 374 km2 and 200 000 inhabitants is located in the North of Mozambique Channel in the Indian Ocean (Figure1). In response to the threat of the pandemic influenza A(H1N1)2009 virus emergence, a syndromic surveillance system has been implemented in order to monitor its spread and its impact on public health (1). This surveillance system which proved to be useful during the influenza pandemic, has been maintained in order to detect infection diseases outbreaks.

Objective

To present the usefulness of syndromic surveillance for the detection of infectious diseases outbreak in small islands, based on the experience of Mayotte.

On October 2016, the Indian Ocean Regional Health Agency was alerted about an increase in ED visits related to adverse reactions associated with use of SC on Mayotte Island. In this context, an investigation based on a syndromic surveillance system was implemented by the regional unit of the French national public health agency.

Objective:

To confirm and to characterize the increase in emergency department (ED) visits related to the use of synthetic cannabinoids (SC).

Description

On January 2, 2014 the cyclone Bejisa struck Reunion Island. This storm of Category 3 (Saffir–Simpson scale) disturbed electricity supply and drinking water systems. Floods, roof destructions and the threat of landslide led to the evacuation of residents to emergency shleters. In this context, the regional office of French Institute for Public Health Surveillance in Indian Ocean set up an epidemiological surveillance in order to assess the impact in the aftermath of the cyclone.

Objective

To assess the health impact of cyclone Bejisa from data of emergency departments (EDs) and emergency medical service (EMS)
