En virtud de la situación de brote de sarampión en Brasil y otros países de la región y el mundo, y la confirmación de un caso en un ciudadano argentino con antecedente de viaje, la Secretaría de Gobierno de Salud emite el presente alerta:

SITUACIÓN ACTUAL

Se confirmó un caso de sarampión en un hombre de 44 años residente en la Ciudad de Buenos Aires, atendido en efector privado, con antecedente de viaje a Brasil, que comenzó con fiebre el día 10 de agosto, agregando exantema cuatro días después. El caso se confirmó por serología (IgM positiva en suero) y seroconversión de IgG, así como RT-PCR positiva en orina. Las muestras fueron procesadas por el efector privado y se confirmaron en el Laboratorio Nacional de Referencia ANLIS Carlos G. Malbrán. Se encuentran en desarrollo las pruebas para identificación de genotipo y linaje viral. La fuente de infección está en investigación. Se iniciaron acciones de prevención y control en los contactos del caso, quienes se encuentran en seguimiento…

Cryptosporidiosis Outbreaks — United States, 2009–2017

MMWR  June 28, 2019  V.68 N.25 P.568–572

Radhika Gharpure, DVM1,2; Ariana Perez, MPH1,3; Allison D. Miller, MPH1,4; Mary E. Wikswo, MPH5; Rachel Silver, MPH1,3; Michele C. Hlavsa, MPH1

Summary

What is already known about this topic?

Cryptosporidium is the leading cause of outbreaks of diarrhea linked to water and the third leading cause of diarrhea associated with animal contact in the United States.

What is added by this report?

During 2009–2017, 444 cryptosporidiosis outbreaks, resulting in 7,465 cases were reported by 40 states and Puerto Rico. The number of reported outbreaks has increased an average of approximately 13% per year. Leading causes include swallowing contaminated water in pools or water playgrounds, contact with infected cattle, and contact with infected persons in child care settings.

What are the implications for public health practice?

To prevent cryptosporidiosis outbreaks, CDC recommends not swimming or attending child care if ill with diarrhea and recommends hand washing after contact with animals….

American trypanosomiasis and Chagas disease – Sexual transmission

International Journal of Infectious Diseases April 2019 V.81 N.4 P.81-84

Clever Gomes, Adriana B. Almeida, Ana C. Rosa, Perla F. Araujo, Antonio R.L. Teixeira

Highlights

  • Trypanosoma cruzi infection can be transmitted sexually from males and females to naïve mates.
  • T. cruzi parasites were detected in semen ejaculates from individuals with Chagas disease by nucleic acid techniques.
  • Semen aliquots from humans with Chagas disease instilled into the vagina of naïve female mice resulted in T. cruzi infections.
  • Breeding T. cruzi-infected male and female mice vertically transmitted the infection to progeny mice.

Objective

To contribute to the discussion on the research findings indicating the sexual transmission of American trypanosomiasis and Chagas disease in humans.

Methods

A review of the literature was performed to investigate the routes of transmission of Trypanosoma cruzi parasites and to evaluate the distribution of Chagas disease, which is now found across five continents.

Results

The epidemiological profile of American trypanosomiasis, which is still considered a neglected disease of the poor people of Latin America, has changed over time. A family-based study demonstrated that the blood protozoan T. cruzi can be transmitted sexually from infected males and females to naïve mates.

Conclusions

Evidence that Chagas disease can be transmitted sexually, coupled with the migration of individuals with Chagas disease to previously non-endemic countries and increased travel to endemic countries, has implications for public health. Improved screening of blood supplies and prenatal care are required to prevent congenital spread.

Brotes por microorganismos resistentes relacionados con el turismo médico

Alerta Epidemiológica 16 de abril de 2019

Brotes por microorganismos resistentes relacionados con el turismo médico

Ante el incremento de brotes causados por microorganismos resistentes relacionados con el turismo médico, la Organización Panamericana de la Salud / Organización Mundial de la Salud (OPS/OMS) orienta a los Estados Miembros a fortalecer la capacidad de detección y manejo de infecciones ocasionadas por microorganismos resistentes en pacientes que viajaron para ser atendidos en un país diferente del que residen.

Al mismo tiempo, la OPS/OMS les urge a implementar medidas preventivas para reducir las infecciones asociadas con la atención de salud en todos los niveles del sistema de salud.

Imported toxin-producing cutaneous diphtheria— Minnesota, Washington, and New Mexico, 2015–2018.

MMWR Morb Mortal Wkly Rep March 29, 2019 V.68 N.12 P.281-284

Griffith J et al.

Summary

What is already known about this topic?

Cutaneous diphtheria has not been notifiable in the United States since 1980, and U.S. disease incidence data are limited.

What is added by this report?

Toxin-producing Corynebacterium diphtheriae was identified in cutaneous wounds from four U.S. residents after return from international travel. Public health response for toxin-producing diphtheria includes treating patients, providing chemoprophylaxis to close contacts, testing patients and close contacts for C. diphtheriae carriage, and providing diphtheria toxoid–containing vaccine to incompletely immunized patients and close contacts.

What are the implications for public health practice?

Cutaneous toxin-producing diphtheria should be considered in travelers with wound infections who have returned from countries with endemic disease to permit prompt public health response and prevent disease transmission.

 

From September 2015 to March 2018, CDC confirmed four cases of cutaneous diphtheria caused by toxin-producing Corynebacterium diphtheriae in patients from Minnesota (two), Washington (one), and New Mexico (one). All patients had recently returned to the United States after travel to countries where diphtheria is endemic. C. diphtheriae infection was not clinically suspected in any of the patients; treating institutions detected the organism through matrix-assisted laser desorption/ionization–time-of-flight mass spectrometry (MALDI-TOF) testing of wound-derived coryneform isolates. MALDI-TOF is a rapid screening platform that uses mass spectrometry to identify bacterial pathogens. State public health laboratories confirmed C. diphtheriae through culture and sent isolates to CDC’s Pertussis and Diphtheria Laboratory for biotyping, polymerase chain reaction (PCR) testing, and toxin production testing. All isolates were identified as toxin-producing C. diphtheriae. The recommended public health response for cutaneous diphtheria is similar to that for respiratory diphtheria and includes treating the index patient with antibiotics, identifying close contacts and observing them for development of diphtheria, providing chemoprophylaxis to close contacts, testing patients and close contacts for C. diphtheriae carriage in the nose and throat, and providing diphtheria toxoid–containing vaccine to incompletely immunized patients and close contacts. This report summarizes the patient clinical information and response efforts conducted by the Minnesota, Washington, and New Mexico state health departments and CDC and emphasizes that health care providers should consider cutaneous diphtheria as a diagnosis in travelers with wound infections who have returned from countries with endemic diphtheria.
