AI Article Synopsis

  • - The report discusses a case of fatal canine visceral leishmaniasis (VL) in a 2-year-old pug from Brazil, which was imported to French Guiana, a region not typically associated with this disease.
  • - The dog initially showed a skin issue that healed, but later developed serious symptoms, leading to suspicion of VL, which was confirmed posthumously by testing for L. infantum.
  • - This case highlights the rarity of canine VL in French Guiana and suggests a need for increased local surveillance to monitor potential transmission routes of the parasite.

Article Abstract

Here we described a case of fatal canine visceral leishmaniasis (VL) in French Guiana, a non-endemic VL Amazonian area. The dog was a 2-year-old pug imported from Brazil to French Guiana. Initially seen for a pruriginous lesion on the muzzle which healed after treatment, the dog was in a deteriorated condition and had sublingual, foreleg and eye ulcers, one month later. A visceral leishmaniasis was suspected by the veterinarian. The dog was hospitalized awaiting results, which revealed the presence of L. infantum. However, the dog succumbed suddenly before the results were returned. Few imported and scarce autochthonous canine VL cases have been previously reported in French Guiana, raising the need for local epidemiological surveillance, considering the possibility of unusual transmission routes of the parasite.

Background: Scurvy, historically rare in-high income countries, has re-emerged as an indicator of socioeconomic and dietary disparities. Limited data exist on scurvy trends among European children, particularly following socioeconomic changes since the COVID-19 pandemic. This study analysed scurvy incidence trends among French children over a nine-year period, examining potential post-pandemic increases.
