CDC estimates* that, from October 1, 2019, through February 29, 2020, there have been:
34,000,000 – 49,000,000
flu illnesses
16,000,000 – 23,000,000
flu medical visits
350,000 – 620,000
flu hospitalizations
20,000 – 52,000
flu deaths
*Because influenza surveillance does not capture all cases of flu that occur in the U.S., CDC provides these estimated ranges to better reflect the larger burden of influenza. These estimates are calculated based on CDC’s weekly influenza surveillance data and are preliminary.
