H1N1 Cases Vastly Underreported, CDC Says
from the Wall Street Journal
WASHINGTON -- The number of confirmed cases of H1N1 flu from April to July represents just 2% of the actual people who were infected with the virus, according to a report by the Center for Disease Control and Prevention.
The report, posted to the agency's Web site, says the number of people infected with H1N1 flu from April to July likely was between 1.8 million and 5.7 million, much higher than the 43,677 confirmed cases. The paper also said the virus hospitalized 9,000 to 21,000 people during the same period.
The study shows the prevalence of the virus is more widespread than originally reported. The CDC and World Health Organization in July stopped tracking individual cases because they acknowledged doing so was difficult.
