Question

3. (2 points) The prevalence of cryptosporidiosis (a parasitic disease causing diarrhea which is commonly associated with drinking contaminated water) in a Burmese refugee camp was 13% in April. In May, Aid workers were able to drill a new well providing a source of clean water. Additionally, during May, 10% of those already infected with cryptosporidiosis died and 50% recovered. In June, an influx of relatively healthy new refugees, none of whom had cryptosporidiosis, increased the camp's population by 15%. What would you expect the prevalence of cryptosporidiosis to be in June compared to April? (Circle one) a. The prevalence would be the same b.
