- What did Ronald Ross find in the stomach wall of an Anopheles mosquito on Mosquito Day, 20 August 1897?
- How did Ross trace the malaria parasite's path through a mosquito's body to prove transmission?
- What practical public-health strategy followed directly from Ross's discovery?
- Where was mosquito-control logic applied successfully enough to measurably cut malaria deaths?
Malaria
The disease, its parasite, and efforts to control it.
- What did the miasma theory of malaria claim, and where did that idea originally come from?
- Which Italian researchers confirmed and extended Ross's work on the mosquito transmission cycle?
- What priority dispute arose between Ross and the Italian research group, and why?
- What exactly did Laveran see under the microscope that led him to identify the cause of malaria?
- Why was it significant that Laveran identified a protozoan, rather than a bacterium, as the cause of a human disease?
- Why did it take twenty-seven years between Laveran's discovery and his Nobel Prize?
- How did Wagner-Jauregg use malaria to treat neurosyphilis?
- What observation led Wagner-Jauregg to try inducing fever in his patients?
- Why was DDT's tendency to persist on surfaces for months so useful for malaria-control programmes?
- How did DDT spraying campaigns change malaria rates in Southern Europe, Africa, and South Asia after World War II?
- How was DDT used in wartime and postwar public health campaigns before its risks were understood?
- Why are malaria-carrying mosquitoes especially attracted to human feet?
- What shared bacteria connects the smell of Limburger cheese to the smell of feet?
- How did this finding lead to a practical tool for controlling mosquito populations?
- Why did earlier high-temperature extraction methods fail to find artemisinin?
