What is the difference between H1N1 and seasonal flu?
Influenza, also called seasonal flu, is a contagious respiratory illness caused by influenza viruses. It can cause mild to severe illness, and at times can lead to death. According to the Centers for Disease Control (CDC) every year in the U.S. about 36,000 people die from flu. Flu symptoms include a sudden onset of high fever, chills, a dry cough, headache, runny nose, sore throat and muscle and joint pain.
In April, a new flu called H1N1 emerged. It's a new virus that until recently, humans had never been infected with. This virus is dangerous because the human immune system has no immunity. Typically the seasonal flu is found to be most dangerous to those with weak immune systems, such as the young and elderly; H1N1 appears to be mostly a threat to healthy, young adults.
"The best way to fight influenza is to get the vaccine," said Jeffrey A. Westpheling, MD, MPH, St. Luke's Work Well Solutions. "Each year scientists determine which types and strains of viruses are likely to circulate in a given year and create the flu shot based on these predictions. This year it's recommended individuals get the seasonal flu vaccine. The H1N1 vaccine is expected to be ready this fall. The seasonal flu vaccine is not expected to protect against H1N1 flu."
The CDC's Advisory Committee on Immunization Practices (ACIP) has recommended that certain groups of the population receive the H1N1 vaccine when it becomes available. These key populations include pregnant women, people who live with or care for children younger than six months of age, healthcare and emergency personnel, persons between the ages of six months and 24 years old and persons 25 through 64 years of age who are at higher risk for H1N1 because of chronic health disorders or compromised immune systems.
"If someone does get the H1N1 flu, there are antiviral drugs that help fight the flu," said Dr. Westpheling. "This fall, antivirals may be prioritized for persons with severe illness or those at higher risk for flu complications."
"If you're not feeling well it's important you stay home until you feel better," said Dr. Westpheling. "If the illness is severe call your doctor. This is a good time for parents, caregivers and businesses to develop contingency plans to deal with missed school, work or ill employees."
Dr. Westpheling stresses people need to stay informed regarding the availabity of H1N1 flu shots and any updated information or advisories.
"People should keep the risk for contracting H1N1 in perspective and not panic," said Dr. Westpheling. "Practicing good hygiene, avoiding close contact with infected individuals and getting vaccinated will lessen the chances of getting seasonal flu and H1N1."
Ways to prevent the spread of flu:
- Cover your nose and mouth with a tissue when you cough or sneeze. Throw the
tissue in the trash after you use it. - Wash your hands often with soap andwater, especially after you cough or sneeze. Alcohol-based hand cleaners
are also effective. - Avoid touching your eyes, nose or mouth. Germs spread that way.
- Stay home if you are sick. The CDCrecommends that you stay home from work or school and limit contact with
others to keep from infecting them.
