The California Department of Health Services monitors influenza (flu) activity in the state. By all measures, the peak of activity in California was two or three weeks ago. Click here for their weekly report.
There are still new cases, and the season is by no means over, but each week has seen fewer new cases than the week before. The national Centers for Disease Control (CDC) still recommends having the flu vaccine if you are 50 years-old or older or are at high risk for complications from influenza. The vaccine should be given as early as possible in the season, but for those who are still unvaccinated, the CDC recommends giving the vaccine as late as May. You can review the CDC recommendations for the flu vaccine here. You can learn general information about flu prevention and what to do if you get sick here.
