Hi Mo2men,

I imagine that the host can be any animal (including people).
Yes, the deer tick can pick up Lyme from an infected animal and then transfer it to a person.
Which part of the question confuses you?

Cheers,
Brent



Hi Brent,

If people are not considered as 'host', then simply choice B is invalid. The tick can pick up Lyme from an anime (excluding human beings) during its adult stage and then bite a human being. But according to you, a human being is host too. So B makes sense.

The problem in that question is that I did not know what tick is but I took word 'deer tick' as if there a deer and its type called 'tick'. I did not understand until I googled it and understand what tick looks like. Then comes word 'host' and its definition. So the confusions stem from many places.

Thanks from help out as always

You're right, much of the question centers on the definition of "host"

I think the most important word in the question stem is "One Host" this tells us that deer ticks do not change the host (if deer tick feeds on a person A, it wont feed on person B) hence if the deer tick acquires an infection in adult stage (from Person A) it wont Transmit it back to person A (he/she is already infected!!). So B makes sense!

The difficulty i faced in this question was an important assumption that the deer tick can transfer the disease via feeding only.

If you assume this then Option A is ruled out because the disease can also be transferred if a tick, infected in its larval or nymph stage, feeds on humans during adult stage.

Please correct me if I am wrong.
