Border Infectious Disease Surveillance -
Coccidioidomycosis (Valley Fever)?
Coccidioidomycosis, commonly known as Valley Fever, is a fungal disease
that primarily affects those living in
the southwestern states of the US. An
individual may become infected by
inhalation of spores present in the soil. Coccidioidomycosis has been on the
rise in California since 2014. The
San Diego County region has environmental factors favorable to the
proliferation of Coccidioides fungi, making it a regional public
BIDS conducted enhanced surveillance for coccidioidomycosis in
San Diego County from October 2014
to December 2016 to describe the
characteristics and exposures of patients with coccidioidomycosis in San Diego County. The Epidemiology & Immunization
Services Branch of the County of San Diego Health and Human Services Agency
reported all coccidioidomycosis cases to BIDS. Lab results and medical records
were reviewed to determine if cases could be classified as confirmed and
whether they were an acute or chronic case. Any confirmed
case that was classified as acute was contacted for an in-depth interview to
capture detailed information
on possible exposures, symptoms, hospitalization
details, travel and occupational history during the incubation period.
and clinical characteristics collected through
evaluation of lab results, medical records, and patient interviews will help
BIDS develop and implement targeted campaigns
to reach those who are most at risk.
Confirmed cases will also be mapped to the regions within San Diego County to
determine if any area has an increased risk of coccidioidomycosis.
