Nosocomial Transmission of Plasmodium falciparum Malaria, Spain, 2024 (Response)
Suggested citation for this article
In Response: We appreciate the opportunity to respond to the letter from Dr. Perales (1) regarding our article on a case of nosocomial transmission of Plasmodium falciparum during a thyroid scintigraphy (2). The author of the letter proposes as an alternative mechanism the nosocomial transmission of the parasite by contact with blood on gloves not changed between patients. We respectfully disagree because the mechanism he proposes lacks scientific basis; no evidence of malaria transmission by such contact has been documented. On the contrary, nosocomial transmission of P. falciparum by parenteral route is well demonstrated, through blood transfusions, transplants (3), or invasive medical procedures involving exposure to contaminated blood (3), as occurred in our case (2).
