Why doesn't CDC base its seasonal flu mortality estimates only on death certificates that specifically list influenza? What are seasonal influenza-related deaths? Seasonal influenza-related deaths are deaths that occur in people for whom seasonal influenza infection was likely a contributor to the cause of death, but not necessarily the primary cause of death.

Does CDC know the exact number of people who die from seasonal flu each year? CDC does not know exactly how many people die from seasonal flu each year. There are several reasons for this. First, states are not required to report individual seasonal flu cases or deaths of people older than 18 years of age to CDC.

Second, seasonal influenza is infrequently listed on death certificates of people who die from flu-related complications. Also, most people who die from seasonal flu-related complications are not tested for flu, or they seek medical care later in their illness when seasonal influenza can no longer be detected from respiratory samples.

Sensitive influenza tests are only likely to detect influenza if performed within a week after onset of illness. In addition, some commonly used tests to diagnose influenza in clinical settings are not highly sensitive and can provide false negative results i. For these reasons, many flu-related deaths may not be recorded on death certificates.

These are some of the reasons that CDC and other public health agencies in the United States and other countries use statistical models to estimate the annual number of seasonal flu-related deaths. Flu deaths in children are different though because these are nationally notifiable, which means that individual flu deaths must be reported to the Centers for Disease Control and Prevention.

Why does CDC estimate deaths associated with seasonal flu? CDC feels it is important to convey the full burden of seasonal flu to the public. Seasonal flu is a serious disease that causes illness, hospitalizations, and deaths every year in the United States.

As previously explained, flu-associated deaths in adults are not a nationally notifiable condition, and so states are not required to report flu-associated deaths in adults to CDC. In contrast, flu-associated deaths in children are a nationally notifiable condition, and so jurisdictions inclusive of state, city or local public health departments do provide data to CDC on flu-associated deaths in children.

Based on available data, this remains true for the season, as well. For the latest surveillance data on flu deaths in children, see https: CDC uses two categories of underlying cause of death information listed on death certificates: CDC uses statistical models with records from these two categories to make estimates of influenza-associated mortality.
