San Mateo County Health System's Communicable Disease Control Program works closely with the California Department of Public Health (CDPH), San Mateo County providers, school officials, community members, and private organizations to protect the health of our residents and visitors.
Our staff includes physicians, public health nurses and communicable disease investigators (CDIs).
We track reports of over 80 reportable diseases, investigate individual cases of communicable diseases and their contacts, monitor outbreaks in the community, recommend public health actions to control the spread of disease, and alert clinicians to public health threats. We also conduct special studies and projects, and produce guidelines, manuals, special analyses and quarterly reports.
To control and prevent the spread of communicable diseases in San Mateo County, we work closely with multiple groups, including our epidemiology partners, the Immunization program, Environmental Health, the Peninsula Humane Society and SPCA, and the San Mateo County Mosquito and Vector Control District.
