Corona virus in Madagascr and CVB response -- Worth to read

The World Health Organization has declared a global public health emergency in response to the Novel Coronavirus (COVID-19) Pandemic and there is now evidence of infection with the virus causing COVID-19 in Madagascar.1 As we prepare for this public health emergency, we must also recognize the potential threat of this pandemic to Madagascar's lemurs. Wild chimpanzees have experienced respiratory outbreaks following infection by human coronaviruses2 and it is highly probable that chimpanzees and other non-human primates, such as lemurs, are similarly susceptible to the virus causing COVID-19. Scientific research, ecotourism, and current conservation and management paradigms all have the capacity to subject habituated wild primates to risks of human pathogen exposure. Considering these risks it is recommended to suspend lemur tourism and reduce research activities subject to risk assessments to maximize conservation outcomes (for example, poaching or deforestation of lemur habitat could rise with fewer people in the vicinity). The IUCN Best Practice Guidelines for Health Monitoring and Disease Control in Great Ape Populations,3 were developed in response to a series of mortality events in habituated apes linked to human respiratory virus exposure4-6 and a greater recognition of the ease of wild ape exposure to human enteric pathogens.7,8 Fortunately, the majority of these guidelines are broadly applicable to habituated primates and are particularly relevant to the current COVID-19 pandemic. Implementing the following key guidelines across ecotourism and research sites in Madagascar for essential staff who continue to enter lemur habitat during the pandemic will substantially reduce the risk of lemur exposure to the virus causing COVID-19 or the multitude of other pathogens we may unintentionally introduce when we enter lemur habitats: 1) Sick? Stay home: No individual with clinical symptoms (i.e., nasal discharge, sore throat, cough, or fever) should enter lemur habitat). 2) Start clean for each visit: Individuals entering lemur habitat should wear clean clothing. Footwear should be disinfected and hands should be washed with soap and water before entering and again upon leaving habitat. 3) Stay away: Individuals should maintain a minimum distance of 7 meters from lemurs. 4) Wear a facemask: Individuals within 10 meters of lemurs should wear a surgical mask. 5) Sneeze right: If an individual must sneeze or cough while in proximity to lemurs, they should keep their mask on, turn away from animals, and cover mouth and nose with the crook of the elbow rather than the hand, or sneeze inside their clothing. The current COVID-19 pandemic should be considered a potential threat to the health of wild lemurs. There is no such thing as zero disease risk and taking measures to prevent or control disease will never eliminate all risks, therefore the recommendations herein are primarily aimed at minimizing, rather than trying to eliminate, the threat of disease transmission from humans to wild lemurs. Despite this caveat, implementing these best practices should substantially reduce the risks that human activities pose to lemur health and signal a clear commitment to primate conservation in Madagascar. 1https://www.who.int/emergencies/diseases/novel-coronavirus-2019 2Patrono, L.

Désormais, 95% des espèces de lémuriens présentes à Madagascar sont en danger d'extinction.

La vaste majorité des lémuriens, ces primates endémiques de Madagascar, sont en danger d'extinction. Voilà ce qu'on apprend sur la dernière liste rouge des espèces en danger, publiée par l'IUCN (Union internationale pour la conservation de la nature ). Sur les 111 espèces de lémuriens connues, 105 sont actuellement "en danger critique d'extinction", "en danger" ou "vulnérable", renforçant le statut des lémuriens comme primates les plus menacés sur la planète.

Portail des lémuriens pour Madagascar: Lancement officiel

Un des facteurs de l’échec de la conservation des lémuriens est lié à la non-disponibilité des informations accessibles à tout le monde et aux faibles connaissances des parties prenantes impliquées dans les activités de conservation. Plus précisément, un mécanisme robuste manque encore pour créer des boucles de rétroaction positive entre la recherche, les décisions politiques, et les actions de conservation. Donc entre nous, acteurs de la conservation de notre patrimoine, chacun à notre niveau. C’est de cette problématique qu’est né le projet « Portail des Lémuriens pour Madagascar – Madagascar Lemurs Portal ». Financé par JRS Biodiversity Foundation, une fondation basée aux Etats-Unis, le portail des lémuriens est développé pour que toutes les parties prenantes et les acteurs de la conservation des lémuriens puissent consulter et partager les informations et les connaissances qui contribueront à termes à une amélioration de la conservation des lémuriens. Ce sera le premier portail en Afrique consacré spécifiquement aux primates. C'est un de ces outils innovants de la conservation de la biodiversité qui offre différentes facettes selon les besoins des utilisateurs. Un forum en ligne, une base de données exhaustive, une visualisation cartographique, et une application mobile sont actuellement disponibles pour l’utilisation publique. Tout cela a pour objectif de contribuer à la création de cette boucle de rétroaction positive entre la recherche, la conservation, et les décisions relative à la protection des lémuriens.
