An updated version of the 2018 flu statistics formula can be found here.

The 2018 formula is based on a new formula developed by CDC officials to provide a more accurate flu tracking tool for consumers.

According to a CDC spokesperson, the updated formula uses a different method of calculating the number of flu cases each state sees, which could result in more accurate numbers than the previous formula.

In the old formula, states saw up to 15,000 cases per week, but the new formula gives a maximum of 15,700 cases per month.

The CDC said that the new estimate of 15.6 million cases is the most accurate since the original formula was developed in the early 1990s.

The formula is available here and is also available on the CDC website.
