Question

2.) What is meant by "patient zero"? Explain what it means in the context of Typhoid Mary, as well as what they mean when they use this term to describe the origins of HIV. How are the meanings different?

Answer 1

In case of typhoid Mary , the patient zero was contagious, but asymptomatic , just a carrier of the disease typhoid which she infected many.

In case of HIV , gaetan dugas was mis-considered as patient zero . His file said patient o o representing outside of Canada . But people misjudged and read it as patient zero .

The meaning is completely different , cause typhoid Mary was a an asymptomatic carrier , contagious to everyone around her. But whereas incase of HIV a patient cannot be contagious by just being around him . And the term itself was a misconception.
