Valley fever cases are expected to increase in the San Joaquin Valley as summer approaches, driven by more outdoor work and play. The fungal disease, which causes respiratory issues, has no vaccine.
- Over 1,200 cases reported in early 2026 across eight counties. - Kern County remains the hotspot with 46,000+ cases since 2001.
- Actual cases may be 10-18 times higher due to underreporting. - Symptoms mimic other respiratory illnesses; rare cases can cause meningitis.
Health officials urge awareness, especially for outdoor workers and those with weakened immune systems.
