He said he asked the Institut Pasteur but also the Poison Control Center "to involve their teams in the search for the causes". "The disease is not linked to COVID-19, since the tests carried out on those affected have been negative and there is also no presence of virus, which can suggest a toxic origin even if we do not cannot say so categorically, "he added.

      Senegal, Mysterious disease: more than 700 people affected, the authorities' trail

      Nov 20 , 2020

      The mysterious dermatological disease that was detected a few days ago among fishermen in Thiaroye-sur-Mer, Senegal, is taking worrying proportions, with more than 700 people infected.

      The Senegalese health authorities are hard at work to try to contain the mysterious disease which has appeared among the fishermen of Thiaroye-sur-Mer, and which has spread to other localities, such as Mbour (85 km from Dakar), Saint-Louis (272 km north of Dakar), Mbao (another Dakar suburb), Touba Dialaw (70 km from Dakar), Rufisque (town 25 km from Dakar) and Y?ne (60 km from Dakar).

      This disease, the origin of which is currently unknown, is manifested by pimples on the face, arms, lips, private parts, not to mention that the eyes of those affected are watery. Abdoulaye Diouf Sarr, Senegalese Minister of Health and Social Action, rules out a viral origin and makes the toxic trail serious, ensuring that all arrangements are being made in collaboration with his counterparts for the Environment and the Peach.


      What we can say today is that it is not related to Covid because the tests came back negative. We also did not see the presence of virus, which can make us think of a toxic origin but we cannot, at that moment, say it "

        Dermal disease that affects fishermen: Minister Abdou Karim Sall suspects an algal origin Dermal disease that affects fishermen: Minister Abdou Karim Sall suspects an algal origin The Ministers of Fisheries, Health and the Environment were present this Friday in Rufisque to visit fishermen infected with skin diseases and isolated in the enclosure of the Ngalandou Diouf stadium. Taking the floor, the Minister of Environment and Sustainable Development, Abdou Karim Sall, informed that "samples in number of ten (10) were taken. 2 concerning fish, 4 concerning sea water and 4 others concerning algae. Analyzes are in progress and will not fail to reveal in the coming hours the exact causes which started this disease ". Mr. Sall to point out that the samples were taken at sea 8 km from Ndayane (a Lebou village in western Senegal, located on the Petite-C?te south of Dakar, 50 km). Minister Abdou Karim Sall nevertheless has suspicions concerning the origin of the mysterious pathology. "There are strong enough suspicions about the Algale origin, but these are things that will have to be confirmed with the analyzes," he said. Before informing that "of the 200 fishermen interned in this stadium (Ngalandou Diouf), some will go out in the hours which follow. Tests have confirmed that there was no contamination". On site, the PressAfrik team saw that the patients' situation is improving. The Minister of Fisheries, Alioune Ndoye, moreover wished to reassure the Senegalese populations on the absence of risk to consume products from the sea. "The fish dumped on the market are the subject of analysis and certification as to their consumable nature of these products ". According to him, the Senegalese have nothing to fear regarding the consumption of the poison, after the discovery of this skin disease in Thiaroye / Mer. In this video, the chief physician of the District of Rufisque takes stock of the medical care of patients with dermatoses ...

          Senegal: The first results of the investigation into the mysterious disease affecting fishermen revealed

          Posted by on Monday 23 November 2020 at 07:44

          As part of the investigation into the causes of the mysterious disease that appeared on fishermen operating on the Senegalese coasts, the Directorate of the Environment and Classified Establishments (DEEC) commissioned the Regional Center for Research in Ecotoxicology and Environmental Safety ( CERES-Locustox) as a laboratory to perform analyzes by gas chromatography coupled with mass spectrometry (GC-MS) of seawater samples taken at georeferenced points.

          Thus, on Thursday, November 19, a mixed team, made up of two agents from CERES-Locustox, an agent from the DEEC, an environmental gendarme and a representative of the Fishermen's Association, took samples at the level of four sites from Dakar to Popenguine.

          Three samples of seawater, a sample of a fisherman's equipment (gloves) and four samples of fish were taken there, according to the document we obtained a copy of.
          `` The analyzes requested by the DEEC are a broad screening of samples for the search for pesticides, PAHs, drug residues as well as the GC-MS screening of samples using the NIST library '', we note in the same source which specifies that the DEEC has identified the sites and points of sampling.

          Under the supervision of the Gendarmerie de l'Environnement, the samples were taken, packaged in suitable containers and sent to the Environmental Chemistry Laboratory of CERES-Locustox.

          The water analysis was carried out according to the NF EN ISO 6468 method standard for pesticides and PCBs, DMS1 / 2 for PAHs, liquid-liquid extraction by solvent for scanning Scan with GC-MS, the NFEN 15662 standard, QuEChERS method for a GC, MS scan, reading by GC-MS with use of standard solution for the detection of pesticides and PAHs and use of the SCAN method with the PEST and NIST libraries, explains the results of this investigation.

          For analytical quality control, blank samples were injected into the injection sequence to attest to the absence of contamination of the equipment. A seawater sample taken on 01/24/2020 and respecting the storage conditions served as a sample blank.
          Analysis of the seawater did not reveal the presence of PAH I at the limit of quantification of 0.01 mg / l, pesticides at the limit of quantification of 0.01 mg (l, of indicator PCBs.

          However, PCB 32 was detected but at a very low level and with a probability of 690/0.
          Analysis by SCAN showed on all the water samples the presence of phthalic acid (600/0 probability), sulfur with a probability of 96.40 / 0, traces of benzene dicarboxylic acid with a probability of 480/0, hexadecanoic acid with a probability of 51 0/0, ethanol with 200/0 probability.

          The SCAN analysis also revealed the presence of phthalic acid, oxalic acid, sulfur and benzenedicarboxylic acid on the fisherman's glove.

          "Our results establish that the source of pollution is not PAHs (16 congeners), PCB Indicators, pesticides of all families, drug residues. Thus, at their limit of quantification (0.01 mg / liter), these chemicals have not been detected, '' reassure the investigators.

          '' In view of the '' almost permanent '' presence in the four water samples of phthalic acid, sulfur, benzene dicarboxylic acid and hexadecanoic acid, we suggest to submit these results to 'analysis to toxicologists and to direct research on the nets used by fishermen,' 'they conclude.

He also reassured that there is no risk in consuming the fish. The other good news, according to the Minister of Health, is that at the level of the investigations, there are no secondary cases, in other words, it is not a contagious disease.

            Regarding the investigations, Abdoulaye Diouf Sarr rejects any idea of ​​slowness. "Because, he underlines, the research obeys a process and successive assumptions", thus praising the effectiveness of Senegalese scientists.

              Senegal: The skin disease affecting fishermen remains a mystery

              HEALTH More than 1,000 fishermen have been affected by rashes on limbs and face last week

              But it is still unclear what causes the evil which, according to images posted by media and social networks, has covered fishermen with sometimes impressive pimples on their faces and limbs,

              "The results of the laboratory tests did not reveal an infectious cause, but further investigations are underway," he said. Samples analyzed by a laboratory did not reveal any chemical or toxic infection of the water or fish, said the Minister of the Environment. It remains to analyze the samples from the algae, the appearance of the disease having coincided according to the fishermen with a proliferation of algae. Analyzes carried out by the poison control center at Cheikh Anta Diop University in Dakar are scheduled for this week. The minister is also considering analyzes on fuel and nets.
