Synopsis for August 11, 2000
Fatal Illnesses Associated With a New World Arenavirus California, 1999 2000
Preventive measures for arenavirus infections include control of rodent populations and their exclusion from human
dwellings.

The California Department of Health Services (CDHS) and University of Texas Medical Center recently identified evidence of infection with an
arenavirus in three patients hospitalized with similar fatal illnesses. This report summarizes the investigation of this outbreak. Arenaviruses
are rodent-borne enveloped RNA viruses and broken down into two groups, Old World and New World. Several arenaviruses cause viral hemorrhagic
fever syndromes in Africa and South America. The South American hemorrhagic fever viruses belong to the Tacaribe complex or New World arena
viruses (e.g., Junin, Machupo, Guanarito, and Sabia). The Old World arenaviruses include the agents of Lassa fever and lymphocytic
choriomeningitis (LCM). LCM associated with the house mouse Mus musculus is the only Old World arenavirus that occurs in the Americans.
State-Specific Prevalence of Disability among Adults 11 States and the District of Columbia, 1998
Standard questions are needed to conduct surveillance of disability at the state and national level.

The work represents the first state-level prevalence analysis of disability from the BRFSS. Uniform data are needed to
guide public health activities, including the implementation of state Healthy People 2010 objectives. CDC analyzed data from the disability
module from BRFSS in eleven states and the District of Columbia to estimate state-level prevalence of disability. Positive response to either of
two questions addressing activity limitations or use of assistive equipment to get around constituted the case definition. The average
prevalence rate was 17.1%, consistent with national estimates ranging from 15% - 20%. State prevalence rates varied considerably, ranging from
13.6% to 21.8%. Rates increased with age: ages 18-44 ranged from 6.3% to 12.8%, averaging 9.7%; ages 45-64 ranged from 16.6% to 31.2%, averaging
22.1%; age 65 and older ranged from 26.2% to 40.4%, averaging 30.8%.
Update: West Nile Activity Northeastern United States, January 1 August 7, 2000
The data in this report suggest an expanding zone of epizootic transmission in four northeastern states with viral
activity most intense in the NYC area.

Surveillance programs initiated in response to the 1999 West Nile virus (WNV) outbreak have detected increased
transmission activity in the northeastern United States. Seventeen states along the eastern seaboard and gulf coast, New York City (NYC) and
Washington, D.C., have conducted WNV surveillance and are reporting to CDC. Surveillance includes monitoring of mosquitos, sentinel chicken
flocks, wild birds, and potentially susceptible mammals such as horses and humans for WNV infection. This report summarizes findings of this
surveillance system through August 7, 2000.
