I am a med student from the US and am currently taking a Malaria class in Brazil. We are learning how to identify malaria. I have a couple questions. How many hours of clinical practice does someone need to get this down in the USA? I know our lab here has been critizied for teaching the class at 4hrs a day for two months. I will be having even less practical time. 4 hrs a day for a month. In short... what is the US view on being able to identify after that time? How long to malaria slides last? Giemsa and Walker stains. Would it be a usless effort to try to collect some reference slides of Malaria, T. Cruzi, Filaria and Microfilaria? I would like to continue doing work outside the US and think these may be useful years down the road. Do they have this long of a shelf life? Is this effort kinda pointless anyways?
