[Emerging parasitic diseases].

Area of Science:

• Infectious Diseases
• Parasitology
• Global Health

Background:

• International travel and migration are significant drivers for the emergence and spread of infectious diseases.
• Many emerging infections are zoonotic, with viral origins, but parasitic diseases also pose global health challenges.
• Understanding the epidemiology of less common parasitic infections is vital for public health.

Observation:

• Muscular Sarcocystis infection, an acute illness, is acquired by travelers to endemic areas like Malaysia.
• Chagas disease, a chronic parasitic illness, affects migrant populations from Latin America.
• These diseases present differently, with Sarcocystis causing acute symptoms and Chagas disease having a long incubation period.

Findings:

• Sarcocystis infection requires preventive measures for travelers and prompt diagnosis upon return presenting with fever, myalgia, and eosinophilia.
• Chagas disease necessitates proactive screening of Latin American migrants, who may face barriers to healthcare access.
• Both diseases highlight the need for tailored public health strategies based on disease characteristics and population demographics.

Implications:

• Travelers to Malaysia should be aware of Sarcocystis risks and seek medical attention if symptomatic after their trip.
• Healthcare providers should consider Chagas disease in Latin American migrants, facilitating access to screening and care.
• Effective management of emerging parasitic diseases involves a combination of traveler education, clinical vigilance, and targeted screening of at-risk populations.
