Dengue fever: in Kourou, we go to the lab without ordo
In the space city and until June 30, it is no longer necessary to have a doctor’s prescription to carry out a PCR and/or serological dengue test in the two private laboratories. The objective is to facilitate screening, while an epidemic focus has been identified in the town. This innovation will be evaluated at the end of this period. If successful, it may be renewed during epidemic episodes.
It’s a first ! Since yesterday and until June 30, it is no longer necessary to have a prescription from your doctor to carry out a PCR and/or serological test against dengue, in the private laboratories of Kourou. It was around 8 a.m. when the first residents took advantage of the device, at Biosoleil and Eurofins (formerly Carage). In practice, the person who wants to be tested against dengue goes to the laboratory, is registered at the reception. She answers a questionnaire on her symptoms, her recent trips and the contacts she may have had with the virus. In the next few days, volunteers recruited by the town hall will help the person to fill it out. Follows the blood test and then the result, generally communicated within forty-eight hours by the laboratory. These same results are transmitted to Public Health France for the monitoring of the epidemiological situation. Anyone can come to the laboratory, without it being necessary to be affiliated with Social Security or to have their Vitale card. The tests will be paid for by Social Security.
“By no longer going to the doctor, we hope that residents will not hesitate to get tested in the event of symptoms or if a loved one is sick. We hope to detect cases more quickly and therefore have better visibility on the circulation of the virus. We will thus be able to react more quickly, by launching vector control measures, ”explains Mathilde Hangard, health studies engineer at the ARS. At the same time, a call center is set up at the ARS to call positive people. “This will give them their result back, suggest that they consult their doctor, monitor symptoms and offer personal protective measures such as sleeping under a mosquito net and using repellents,” she continues. Yesterday morning, with Marion Guyot, epidemiologist at Public Health France, she went to town medicine cabinets and community pharmacies to explain the device to health professionals and display posters.
“We are taking over a device that worked during a major epidemic, the Covid. We will thus have a real-time vision of dengue fever, without people wondering whether they are going to be tested or not. It’s a vector-borne disease. It is therefore important to quickly circumscribe epidemic foci. We had never done that,” rejoices Marc Lédy, co-director of the Biosoleil laboratories.
To have a chance of preventing a new epidemic from starting, it is also essential, throughout the country, to have a sample taken as soon as a person shows symptoms of dengue fever and that the laboratories report the cases WITHOUT DELAY ARS positive.
The journal Viruses publishes an overview of arboviruses circulating in French Guiana
Dengue, chikungunya, zika, yellow fever, Oropouche virus, Tonate and Mayaro. Researchers from the Cayenne hospital, the Institut Pasteur de Guyane and Public Health France publish an overview of the main arboviruses circulating in the territory, in the revue Viruses. “This article aims to summarize the current knowledge on these arboviruses in French Guiana and to discuss the challenges posed by the emergence or re-emergence of arboviruses”, explain the authors.
In addition to these seven arboviruses, they discuss the challenges ahead: factors favoring epidemics, vector control, the risk of introduction of Aedes albopictus, one of the most invasive mosquitoes in the world, in French Guiana, the possible emergence new arboviruses… “Effective control measures are hampered by the non-specific clinical presentation of these diseases, as well as by the resistance of the Aedes aegypti mosquito to insecticides, they point out. Despite the high seroprevalence of some viruses, the possibility of new epidemics cannot be excluded. Therefore, active epidemiological surveillance is needed to identify potential outbreaks, and an adequate sentinel surveillance system and a wide panel of virological diagnostics are being developed to improve disease management. »
