Chapter 55. Epidemiology of Malaria
TEST BANK
True/False Questions
- WHO reported that more than 216 million new cases of malaria were diagnosed in the world population in 2016.
- Approximately 85% of new cases of malaria in sub-Saharan Africa are diagnosed in children under 5 years of age.
- Global estimates of the number of deaths caused by malaria reported by WHO have declined from 1.0 million in 1990 to 730,000 in 2015.
- Most malaria cases (98%) are diagnosed in sub-Saharan Africa (86%), Southeast Asia (9%), or the Eastern Mediterranean region (3%).
- According to WHO data, approximately 98% of new malarial infections in the African population are due to Plasmodium falciparum.
- Sickle Cell Anemia, an autosomal recessive genetic disorder, protects red blood cells from infection by Plasmodium falciparum.
- Deficiency in Glucose-6-phosphate dehydrogenase (G6PD), an X-linked trait, protects against infection by Plasmodium falciparum but not Plasmodium vivax.
- Malaria transmission can be reduced substantially by preventing mosquito bites by distribution of inexpensive mosquito nets and insect repellents or by mosquito-control measures such as spraying insecticides inside houses and draining standing water where mosquitoes lay their eggs.
- A disturbing feature in the fight against malaria is the development of large scale resistance by Plasmodia falciparum to several anti-malarial drugs, most notably chloroquine.
- Chloroquine-resistant malaria is most effectively treated using artemisinin-based combinations.
