Background
Estimating the number of individual flu cases in the United States is very challenging because many people with flu don"t seek medical care and only a small number of those that do seek care are tested. More people who are hospitalized or die of flu-related causes are tested and reported, but under-reporting of hospitalizations and deaths occurs as well. For this reason CDC monitors influenza activity levels and trends and virus characteristics through a nationwide surveillance system and uses statistical modeling to estimate the burden of flu illness (including hospitalizations and deaths) in the United States. When the 2009 H1N1 flu outbreak began in April 2009, CDC began tracking and reporting the number of laboratory-confirmed 2009 H1N1 cases, hospitalizations and deaths as reported by states to CDC. These initial case counts (which were discontinued on July 24, 2009), and subsequent ongoing laboratory-confirmed reports of hospitalizations and deaths, are thought to represent a significant undercount of the actual number of 2009 H1N1 flu cases in the United States.A paper in
Emerging
Infectious Diseases authored by CDC staff entitled "Estimates of the Prevalence of Pandemic (H1N1) 2009, United States, April-July 2009" reported on a study to estimate the prevalence of 2009 H1N1 based on the number of laboratory-confirmed cases reported to CDC. Correcting for under-ascertainment, the study found that every case of 2009 H1N1 reported from April - July represented an estimated 79 total cases, and every hospitalized case reported may have represented an average of 2.7 total hospitalized people. CDC then began working on a way to estimate, in an ongoing way, the impact of the 2009 H1N1 pandemic on the U.S. in terms of 2009 H1N1 cases, hospitalizations and deaths. CDC developed a method to provide an estimated range of the total number of 2009 H1N1 cases, hospitalizations and deaths in the United States by age group using data on flu associated hospitalizations collected through CDC'sEmerging Infections Program.
The Numbers
On November 12, 2009 CDC provided the first set of estimates on the numbers of 2009 H1N1 cases and related hospitalizations and deaths in the United States between April and October 17, 2009.Estimates from April - October 17, 2009:
CDC estimated that between 14 million and 34 million cases of 2009 H1N1 occurred between April and October 17, 2009. The mid-level in this range was about 22 million people infected with 2009 H1N1. CDC estimated that between about 63,000 and 153,000 2009 H1N1-related hospitalizations occurred between April and October 17, 2009. The mid -level in this range was about 98,000 H1N1-related hospitalizations. CDC estimated that between about 2,500 and 6,000 2009 H1N1-related deaths occurred between April and October 17, 2009. The mid -level in this range was about 3,900 2009 H1N1-related deaths.Updated Estimates from April - November 14, 2009
Using the same methodology, CDC updated the estimates to include the time period from April through November 14, 2009 on December 10, 2009. CDC estimated that between 34 million and 67 million cases of 2009 H1N1 occurred between April and November 14, 2009. The mid-level in this range was about 47 million people infected with 2009 H1N1. CDC estimated that between about 154,000 and 303,000 2009 H1N1-related hospitalizations occurred between April and November 14, 2009. The mid -level in this range was about 213,000 H1N1-related hospitalizations. CDC estimated that between about 7,070 and 13,930 2009 H1N1-related deaths occurred between April and November 14, 2009. The mid -level in this range was about 9,820 2009 H1N1-related deaths.Updated Estimates from April - December 12, 2009
Using the same methodology, CDC updated the estimates to include the time period from April through December 12, 2009. CDC estimates that between 39 million and 80 million cases of 2009 H1N1 occurred between April and December 12, 2009. The mid -level in this range is about 55 million people infected with 2009 H1N1. CDC estimates that between 173,000 and 362,000 2009 H1N1-related hospitalizations occurred between April and December 12, 2009. The mid -level in this range is about 246,000 H1N1-related hospitalizations. CDC estimates that between 7,880 and 16,460 2009 H1N1-related deaths occurred between April and December 12, 2009. The mid-level in this range is about 11,160 2009 H1N1-related deaths. Updated Estimates from April 2009 - January 16, 2010 Using the same methodology, CDC updated the estimates to include the time period from April 2009 through January 16, 2010 onFebruary 12, 2010.
CDC estimates that between 41 million and 84 million cases of 2009 H1N1 occurred between April 2009 and January 16, 2010. The mid -level in this range is about 57 million people infected with 2009 H1N1. CDC estimates that between 183,000 and 378,000 H1N1-related hospitalizations occurred between April 2009 and January 16, 2010. The mid -level in this range is about 257,000 2009 H1N1-related hospitalizations. CDC estimates that between about 8,330 and 17,160 2009 H1N1-related deaths occurred between April 2009 and January 16, 2010. The mid-level in this range is about 11,690 2009 H1N1-related deaths. Updated Estimates from April 2009 - February 13, 2010 Using the same methodology CDC has again updated the estimates to include the time period from April 2009 through February 13, 2010 on March 12, 2010. CDC estimates that between 42 million and 86 million cases of 2009 H1N1 occurred between April 2009 and February 13, 2010. The mid -level in this range is about 59 million people infected with 2009 H1N1. CDC estimates that between 188,000 and 389,000 H1N1-related hospitalizations occurred between April 2009 and February 13, 2010.
