Flu cases are spreading at very high levels across California, with many areas seeing elevated transmission particularly among children, according to state health officials.

The widespread activity comes as a strain capable of causing reinfections circulates through communities, raising concerns for families and schools in Santee and East County.

Health officials are urging residents who haven't yet received a flu vaccine this season to do so, noting that vaccination remains the most effective protection against severe illness. The flu shot can be obtained at pharmacies, urgent care clinics, and primary care offices throughout East County.

Symptoms of influenza include sudden onset of fever, body aches, fatigue, cough, and sore throat. Children, seniors over 65, pregnant women, and people with underlying health conditions face higher risk of complications.

Parents should keep sick children home from school and childcare to prevent further spread. Hand washing, avoiding touching the face, and staying home when ill are key prevention strategies.

Santee residents experiencing severe symptoms—difficulty breathing, chest pain, persistent high fever, or sudden dizziness—should seek medical attention immediately. Most cases can be managed at home with rest and fluids, but antiviral medications may be prescribed for high-risk patients if started within 48 hours of symptom onset.

Local pharmacies and health clinics continue to offer flu vaccines for anyone who hasn't been immunized this season. While the vaccine doesn't guarantee complete protection, it significantly reduces the risk of severe illness and hospitalization.
