Chagas is trypanosoma Cruzi, on the option listed Nifurmitox is for chagas, and is not listed... So its more likely to go for Tripanozoma brucei o gambiense, to produce Sleeping sickness and the treatment is Suramin for blood borne dx or Melarsoprol for CNS penetration.

Treatment for Leishmania is Sodium Stibogluconate. Sleeping sickness is more likely.

Default we were all wrong!

the ans is benznidazole!

Acute Chagas disease
  • All patients with acute Chagas disease, including those with congenital infection and those with reactivation of chronic infections due to immunosuppression, should be treated with either benznidazole or nifurtimox.
i dont think you are scratching the bite b/c of pain as much as b/c of irritation.
i still think that the mention of south america/colombia means you shld be thinking of chagas

yea u r right. actually scratching skin after bite is the mechanism of entry of protozoa from feces of kissing bug near bite site to blood.
