I am not sure this if of any use and I am nowhere near an expert on this field.
But I found this article by doing a google search for "link malaria parasite hepatitis" : https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3097216/
Hepatitis is a major cause of jaundice (jaundice is a symptom after all, of the underlying disease).
So it could be that even if you are infected, the symptoms are less pronounced?
Again, I am not an expert. But don't give up hope in doing your own research. Sometimes you will see something that even "experts" miss.
