HEALTH REPORT - Study Increases Estimate of Flu Hospitalizations in the United States
By Cynthia Kirk

Broadcast: Wednesday, September 22, 2004

This is Gwen Outen with the VOA Special English Health Report.

Influenza1 can be life-threatening, especially for the very old or the very young. In the United States, a new study raises the estimate of how many people require hospital care related to the flu. Most cases of influenza in the United States usually happen from November until about April, during the colder months.

Researchers from the Centers for Disease Control and Prevention did they study. They looked at hospital records from the flu seasons between nineteen seventy-nine and two thousand-one. They counted flu-related hospitalizations. Doctor William Thompson led the research.

They found that more than two hundred thousand people are hospitalized each year because of the flu. That is almost two times as many as earlier estimates by the C.D.C.

The researchers say one major reason for the increase is the aging of the population. The number of Americans age eighty-five and older more than doubled in the last thirty years.

Also, the study included the years in the late nineteen nineties when there were more cases of severe forms of the flu. And the researchers noted2 a third reason for the higher number of hospitalizations they found. They considered a greater number of flu-related sicknesses to reach the new estimate. The report appeared in the Journal of the American Medical Association.

The highest rates of influenza-related hospitalizations were among people eighty-five and older. The study found that the risk of hospitalizations increased with age starting at fifty. Those least affected3 were between five and forty-nine years old. Children younger than five had rates similar to those among people fifty to sixty-four.

Influenza is a respiratory illness. It attacks the nose, throat and lungs. It causes a high body temperature and muscle aches and makes people feel very tired. It also causes a dry cough and sore throat. The virus spreads through the air when infected people cough or sneeze.

The C.D.C. says most people who get the flu will recover in a week or two. But some people develop life-threatening conditions like pneumonia4.

In the United States, health officials say an average of about thirty-six thousand people each year die from influenza. They say the best way to prevent the flu is to get vaccinated5 each fall before flu season begins.
