Spatial spread of dengue in a non-endemic tropical city in northern Argentina.

After more than eighty years dengue reemerged in Argentina in 1997. Since then, the largest epidemic in terms of geographical extent, magnitude and mortality, was recorded in 2009. In this report we analyzed the DEN-1 epidemic spread in Orán, a mid-size city in a non-endemic tropical area in Northern Argentina, and its correlation with demographic and socioeconomic factors.

Performance of different Trypanosoma cruzi antigens in the diagnosis of Chagas disease in patients with American cutaneous leishmaniasis from a co-endemic region in Argentina.

Methods: Sera from 41 patients infected with Leishmania spp.

Restricted outbreak of American tegumentary leishmaniasis with high microfocal transmission.

Cutaneous leishmaniasis is endemic in Salta, the northwestern province of Argentina. We describe an outbreak involving five recreational hunters whose exposure was limited to several hours in a residual patch of primary forest. All patients presented with typical cutaneous lesions after a mean incubation period of 59 days (range 15-78), and one developed simultaneous mucosal involvement.

Ivermectin-related adverse clinical events in patients treated for Mansonella ozzardi infections.

We report the occurrence of serious reactions after treatment with oral ivermectin in two patients with Mansonella ozzardi infections. Both had systemic and respiratory symptoms and recovered without sequelae. Follow-up revealed clearance of microfilaremia in both cases, with relapse in one of them.
