Homework Help: AIDS risk assessment

  1. Apr 7, 2008 #1
    Canadian Blood Services inquires about a person’s travels before blood donations are accepted. Explain why this practice can be classified as preventive.

    Inquiring about an individual’s travel is a positive practice to preventing HIV occurrences. When travelling to many tropical areas of the world (i.e. Africa), there is a higher risk of contracting infectious diseases.

    But why is there a higher risk?

    How do tropical areas and places like Canada, US, the EU, differ?

    That's a start. How else are they different? Think in terms of how a third world country is different from an industrialised country.

    i guess our economy is higher, more diversity in medicine, more technological advanced. I like how you are doing this Snazzy. I learn better. :)

    That's better. If you've ever been to a third-world country, doctors might give you medication or tell you to do certain things with what you eat or drink. Why is that?
