The course focuses on the diagnostic aspects of parasitic infections of importance in routine clinical practice in European countries. There will be intense practical sessions using high quality clinical samples for microscopy examination, real-life cases and interactive photo quizzes. During the first week the practical sessions will cover about 70% of the course and will be alternated with in-depth lectures given by experts in the field of clinical parasitology. During the second week the focus will be more on the clinical and epidemiological aspects. By the end of the course the participants will be familiar with clinical, diagnostic and therapeutic aspects of most common parasitic infections, including those seen in travellers and immigrants such as malaria, schistosomiasis and intestinal helminths. Some less common parasitic infections will be discussed, as well as the role of molecular diagnostics within routine laboratory practice. This international course is part of a full two weeks course designed for Dutch clinical medical microbiologists in training and experienced senior technicians. The Dutch parasitology course has been successfully organized by the same Leiden group for more than 20 years. International participants can subscribe for week 1 or week 2 or the full course.
