Plasmodium vivax?
Correct! Well done.
Even with only one parasite in the field and a slightly atypical
red cell, you were able to correctly identify this as a typical
"signet ring" form of P. vivax.

Plasmodium ovale?
Sorry! Try again.
A good try but this is not a comet form. Even though the infected red cell is slightly oval, a number of the non-infected red cells are a similar shape.
Have another try and note the patient history which may help.
