A woman in her 60s is Stanislaus County’s first person under the age of 65 years to die from an influenza-associated illness, according to the Stanislaus County Health Services Agency. “This death is a sad reminder that flu can be deadly, especially for people at risk for severe disease” said Dr. Julie Vaishampayan, Stanislaus County Public Health officer. While seasonal flu outbreaks can happen as early as October, flu activity is usually highest between December and February, and can last through the spring.
