cases in 1987
●30 cases in 1988
●Eight cases in 1989
●All caused by P. vivax
Malaria - Life Cycle
●Incubation Period 12 to 14 days
●Sporozoites enter via bite of infected
female anopheline mosquito
●Parasites carried to the liver, where they
multiply inside parenchymal cells
○Preerythrocytic tissue phase
Malaria - Life Cycle
●Progeny released from ruptured
hepatocytes => RBC’s
●Inside RBC
●Progency degrade protein fraction of
hemoglobin
Malaria - Life Cycle
●Undergo asexual maturation from
trophozoite to merozoite
○Process known as schizogony
●Cycles of intracorpuscular multiplication,
rupture, and reinvasion responsible for
paroxysms of chills & fever
Malaria - Life Cycle
●Some parasites differentiate into
macrogametocytes or
microgametocytes, the sexual forms
●These infect mosquitoes that feed on the
victim
Malaria - Life Cycle
●In the gut of the mosquito, the definitive
host
○fertilization
○zygote formation
○production of new sporozoites take place
Clinical Features
●Malaise & Myalgias
●Headache
●Chills (with or without rigor)
Clinical Features
●Temperature to 41.5° C (106.7° F)
●Profuse sweating & Prostration may
appear
●Mild jaundice, hepatosplenomegaly, and
anemia often develop
Fever Patterns
●P. vivax & P. ovale infections cause QOD
(tertian) febrile paroxysms
○After maturation cycles synchronize
○Usually at end of first week
●P. malariae infection marked by
paroxysms Q3D (quartan periodicity)
P. falciparum
●Has capacity to obstruct microcirculation
in various organs
●Fever continuous or intermittent
●Cerebral involvement may lead to
delirium, focal disorders (e.g., seizures),
& coma
P. falciparum
●Splanchnic involvement may cause
protracted nausea, vomiting, diarrhea,
melena, & abdominal pain
●GI syndrome can be mistaken as
traveler's diarrhea
●Since there may be little or no fever
P. falciparum
●Lung involvement may cause pneumonia
& ARDS
●Hypoglycemia may be severe
●Rare syndrome of blackwater fever
○Massive intravascular hemolysis
○=> hemoglobinuria and ARF
P. malariae
●Can persist as an asymptomatic infection
for years or decades
●Usually responsible for late relapses
●This species likely to be cause of malaria
induced by transfusion
Laboratory Diagnosis
●Parasites in properly stained smears
peripheral blood
●Smears taken repeatedly for several
days because cyclic nature parasitemia
●Morphologic features of parasites (and
the infected host erythrocytes) useful in
species ID
Laboratory Diagnosis
●Indirect fluorescent antibody test- CDC
●Blood smear used to establish a Dx
●Serologic test useful in ID infected
donors in cases of transfusion malaria
●DNA probe being developed Dx P.
falciparum infection
