Synopsis for October 18, 2002
Local Transmission of Plasmodium Vivax
Malaria-Virginia, 2002
In August 2002, two teenagers from northern Virginia were infected
with malaria while having no risk factors for acquiring the disease.

Investigations conducted by public health authorities found numerous
mosquitoes competent for transmitting the infection. Subsequent screenings
of these mosquitoes using new rapid tests revealed mosquitoes positive for
Plasmodium vivax malaria. Efforts are underway to develop methods to
confirm these results. The likely source of this outbreak is the bite of a
mosquito infected with the parasite after biting another malaria-infected
individual. No further human cases have been reported. The community is
encourage to practice precautions recommended for West Nile Fever in
reducing exposure to mosquitoes including wearing long sleeved shirts and
long pants, using repellent containing DEET, and avoidance of late evening
outdoor activities.
Q Fever - California, Georgia, Pennsylvania, and
Tennessee, 2000-2001
Q fever is a zoonotic disease caused by Coxiella burnetii.

Its most common reservoirs are domesticated ruminants, primarily cattle,
sheep, and goats. Humans typically acquire Q fever through inhalation of
contaminated dusts generated by animals or animal products. Acute
infections can include self-limited influenza-like illness, hepatitis, and
pneumonia. Chronic Q fever can manifest years or decades after initial
infection, occurs predominantly in patients with valvulopathies or
vascular grafts, and presents most commonly as a culture-negative
endocarditis. During 2000–2001, a total of 48 patients who had a
diagnosis of Q fever were reported to CDC by 19 states through the
National Electronic Telecommunications System for Surveillance (NETSS).
This report describes the case investigations for six of these patients,
which indicate that these persons acquired Q fever probably through direct
or indirect contact with livestock. The findings underscore the need for
health-care providers to be aware of this disease and to report cases to
state health departments or CDC.
First Probable Variant Creutzfeldt-Jakob Disease Case
in a U.S. Resident - Florida, 2002
CDC and the Florida Department of Health report the investigation of
a probable case of variant Creutzfeldt-Jakob disease (vCJD) in a U.S.
resident.

The occurrence of this case was first announced on April 18, 2002. The
patient was likely exposed to the agent of bovine spongiform
encephalopathy (BSE, or “mad cow disease”) while in the United Kingdom
where she was born and lived until 1992, indicating a probable incubation
period of between 9 to 21 years. The investigation indicates that the
patient is unlikely to have transmitted the disease to others. The
occurrence of this case underscores the importance of physicians
increasing their suspicion for vCJD in patients presenting with clinical
features consistent with those of the Florida patient and who have spent
time in areas with endemic BSE.
