Un extrait d'une thèse intéressante : Preventing anaphylaxis to venom of the jack jumper ant (Myrmecia pilosula) :
CITATION United States of America (USA) For the whole of the USA, incidences of 0.14 and 0.18 per million of population per year have been reported in 1963 and 1997 respectively, with the vast majority due to bees, vespid wasps, and paper wasps. Most deaths occurred in the warmer southern states where in 1963 the incidence was estimated at 0.39 per million per year. No statistics are available for the incidence of death due to IFA sting in the USA since the widespread establishment of this introduced pest, largely because of the absence of a specific mortality code to differentiate this cause. Eighty-three deaths, claimed to be caused by IFA but accompanied by minimal clinical data, have been reported. Europe Mortality rates reported from Europe range from 0.2 to 0.45 deaths per million per annum. In Sweden, a mortality rate of 0.2 appears primarily due to wasps (25 of 26 deaths), 160 whereas in Denmark where a mortality rate of 0.26 has been reported, honeybees and wasps were reported responsible for 9/26 (35%) and 15/26 (58%) respectively (in the remaining 2 cases, the cause was uncertain). In Switzerland, with a reported sting anaphylaxis mortality rate of 0.45, honeybees are responsible for the majority (approx 67%) of insect sting allergy where the causative insect can be identified. Australia and Tasmania No overall mortality rate for insect sting anaphylaxis in Australia has been published, however death rates to honeybee sting have been reported at 0.086 per million per annum, wasps at 0.02, and ants at 0.02. Not surprisingly, regional differences are substantial and reflect local climate, insect populations, agricultural and recreational activities. Honeybee sting mortality is especially common in South Australia (mortality rate 0.26 per million per annum). Despite the establishment of Vespula germanica in Tasmania and Victoria, wasp sting mortality in Australia seems to be exclusively due to paper wasps (Polistes and Ropalidia) and confined to northern New South Wales and Queensland. Myrmecia ant sting mortality appears to be concentrated on the island of Tasmania (5 deaths in 20 years, out of a national total of 6). It is likely that deaths due to Myrmecia spp. have been significantly under-reported. A very recent discussion of insect sting allergy in the Australian forensic pathology literature completely ignored the possibility of ant sting allergy as a cause of death. Furthermore, sudden unexplained deaths in rural areas where Myrmecia are common may not always be well investigated, compared to deaths occurring in urban areas serviced by specialist facilities (where bees and wasps are more likely to be encountered than Myrmecia spp.). Je n'ai pas l'impression que l'Australie soit particulièrement plus dangereux que la Suisse. Même si c'est vraisemblablement très sous-estimé, le palmarès des Bullet ant n'est pas si exceptionnel que cela : 6 morts en 20 ans, dont 5 en Tasmanie (donc si on ne met pas les pieds en Tasmanie ...). |

Nous sommes une tranche de la population plus exposée
Si peu de gens meurent de Myrmecia, beaucoup développent des réactions allergiques, et pour en avoir vécu une il y a 2 mois : il vaut mieux s'en passer ... ce n'est pas de tout plaisir Peut-etre faut-il prévoir un antihistaminique pour du terrain prolongé dans ces régions. Ceci dit, il existe aussi un cas reporté de mort par piqure de Hypoponera punctatissima, qui elle est présente en France |
