In the meantime, county health officials are taking a proactive approach to preventing the spread of swine flu in agricultural areas.
They are expected a new wave of seasonal workers from Mexico to arrive around May 1st.
"We're sending some of our public health nurses physically down to the area to provide information, hand out information in wiring and talk to them and see what their needs are," said Dr. Marty Fenstersheib from the Santa Clara County Health Department.
The county will also update its physician alerts, which will clarify who should be tested, and how to properly carry out the nasal swab tests.
In Santa Cruz County, the public health department has activated its operations center to coordinate its response to swine flu. There have been no identified cases in Santa Cruz County.
