Question 85

In 2022, an outbreak of malaria in a remote tropical province resulted in an estimated 2,400 2,400\,2,400 deaths. Local health authorities stated that this figure is only an estimate of the true mortality rate.

Why is the number of deaths from this malaria outbreak reported as an estimate?

The Anopheles mosquito vector cannot be tested for the parasite once a human patient has died.

Most individuals in the province possess complete genetic immunity to malaria, meaning zero deaths could have occurred.

Many deaths occur in remote communities without laboratory or clinical confirmation of the pathogen.

Malaria is caused by a multicellular parasite that is too large to be detected using standard light microscopy.
