influenza flu risk factors

shared by Miranda Blue on 08 Sep 14 - No Cached
  • Age. Seasonal influenza tends to target young children and people over 65. The pandemic H1N1 virus that surfaced in 2009, however, appeared to be most common in teenagers and young adults. Occupation. Health care workers and child care personnel are more likely to have close contact with people infected with influenza. Living conditions. People who live in facilities along with many other residents, such as nursing homes or military barracks, are more likely to develop influenza. Weakened immune system. Cancer treatments, anti-rejection drugs, corticosteroids and HIV/AIDS can weaken your immune system. This can make it easier for you to catch influenza and may also increase your risk of developing complications. Chronic illnesses. Chronic conditions, such as asthma, diabetes or heart problems, may increase your risk of influenza complications. Pregnancy. Pregnant women are more likely to develop influenza complications, particularly in the second and third trimesters.

  • CDC estimates that from the 1976-1977 season to the 2006-2007 flu season, flu-associated deaths ranged from a low of about 3,000 to a high of about 49,000 people. Death certificate data and weekly influenza virus surveillance information was used to estimate how many flu-related deaths occurred among people whose underlying cause of death was listed as respiratory or circulatory disease on their death certificate.

  • MMWR study also found that during seasons when influenza A (H3N2) viruses were prominent death rates were more than double what they were during seasons when influenza A (H1N1) or influenza B viruses predominated.

  • CDC does not know exactly how many people die from seasonal flu each year. There are several reasons for this. First, states are not required to report individual seasonal flu cases or deaths of people older than 18 years of age to CDC.
  • Second, seasonal influenza is infrequently listed on death certificates of people who die from flu-related complications
  • Third, many seasonal flu-related deaths occur one or two weeks after a person’s initial infection, either because the person may develop a secondary bacterial co-infection (such as bacterial pneumonia) or because seasonal influenza can aggravate an existing chronic illness (such as congestive heart failure or chronic obstructive pulmonary disease).
  • Also, most people who die from seasonal flu-related complications are not tested for flu, or they seek medical care later in their illness when seasonal influenza can no longer be detected from respiratory samples. Sensitive influenza tests are only likely to detect influenza if performed within a week after onset of illness.
  • In addition, some commonly used tests to diagnose influenza in clinical settings are not highly sensitive and can provide false negative results (i.e. they misdiagnose flu illness as not being flu.) For these reasons, many flu-related deaths may not be recorded on death certificates.

  • Influenza (the flu) is a respiratory infection.
  • It is caused by the influenza virus.
  • Influenza typically is spread by air or by direct contact from one person to another.
  • ...14 more annotations...
  • Influenza virus is very contagious.
  • Epidemics peak during the winter months
  • Most influenza cases occur during epidemics.
  • With influenza, the virus usually has mutated (changed) somewhat since the first infection.
  • The most common types of influenza virus are A and B. Influenza A is the one usually responsible for the annual epidemics.
  • Most people get multiple flu infections during their lives.
  • With many other types of infections, having the disease once protects against a second infection.
  • That is because the body's immune system remembers the returning virus. It attacks it immediately, and rapidly eliminates it.
  • A particularly widespread and severe epidemic is called a pandemic.
  • Flu can cause a variety of symptoms. They can be mild or severe. Symptoms and severity depend on the type of virus, your age and overall health.
  • Chills Moderate to high fever (101 to 103 degrees Fahrenheit) Sore throat Runny nose Muscle aches Headaches Fatigue Cough Diarrhea Dizziness
  • Vaccination — Vaccination can reduce your chances of getting the flu and transmitting it to others. Vaccination each year is recommended for everyone aged 6 months and older.
  • Good hygiene — The virus usually is passed through the air, by coughing. It also is passed by direct contact, such as shaking hands or kissing.
  • Antiviral drugs — Zanamivir (Relenza) and oseltamivir (Tamiflu) can substantially reduce your chance of getting the flu if they are taken just before an expected outbreak.

  • As of February 28, 2015, flu activity is still elevated but continues to decrease in the United States.
  • more recently, an increase in influenza B viruses has been detected in parts of the country.
  • The flu-associated hospitalization rate among people 65 and older is the highest rate recorded since CDC began tracking that data in 2005.
  • ...17 more annotations...
  • Children 0-4 years of age have the second-highest hospitalization rate this season.
  • Symptoms of influenza infection include fever, chills, cough, sore throat, runny or stuffy nose, muscle or body aches, headache, fatigue (tiredness), and sometimes vomiting and diarrhea (more common in children than adults).
  • The United States experiences epidemics of seasonal flu each year. This time of year is called "flu season." While influenza activity has declined in recent weeks and the flu season is coming to a close, most of CDC’s influenza surveillance systems still show elevated activity.
  • There are several factors that make it difficult to determine accurate numbers of deaths caused by flu regardless of reporting.

  • s very unpredictable and can vary in different parts of the country and from season to season
  • However, seasonal flu activity can begin as early as October and continue to occur as late as May.
  • CDC recommends a yearly flu vaccine(http://www.cdc.gov/flu/protect/vaccine/index.htm) for everyone 6 months of age and older as the first and most important step in protecting against this serious disease.
  • In addition to getting a seasonal flu vaccine if you have not already gotten vaccinated, you can take everyday preventive actions(http://www.cdc.gov/flu/protect/habits/index.htm) like staying away from sick people and washing your hands to reduce the spread of germs. If you are sick with flu, stay home from work or school to prevent spreading flu to others.
  • A number of different manufacturers produce trivalent (three component) influenza vaccines for the U.S. market, including intramuscular (IM), intradermal, and nasal spray vaccines.
  • Multiple studies conducted over different seasons and across vaccine types and influenza virus subtypes have shown that the body’s immunity to influenza viruses (acquired either through natural infection or vaccination) declines over time.
  • Yes. It’s possible to get sick with the flu even if you have been vaccinated (although you won’t know for sure unless you get a flu test). This is possible for the following reasons:
  • You may be exposed to a flu virus shortly before getting vaccinated or during the period that it takes the body to gain protection after getting vaccinated. This exposure may result in you becoming ill with flu before the vaccine begins to protect you. (About 2 weeks after vaccination, antibodies that provide protection develop in the body.) You may be exposed to a flu virus that is not included in the seasonal flu vaccine. There are many different flu viruses that circulate every year. The flu vaccine is made to protect against the three or four flu viruses that research suggests will be most common. Unfortunately, some people can become infected with a flu virus the flu vaccine is designed to protect against, despite getting vaccinated. Protection provided by flu vaccination can vary widely, based in part on health and age factors of the person getting vaccinated. In general, the flu vaccine works best among healthy younger adults and older children. Some older people and people with certain chronic illnesses may develop less immunity after vaccination. Flu vaccination is not a perfect tool, but it is the best way to protect against flu infection.

  • How to prevent the flu and reduce its spread If you have not already done so, get vaccinated. Avoid close contact with others, especially those who are sick. Practice good health habits, such as drinking plenty of fluids, eating nutritious food, getting plenty of sleep, being physically active and managing stress. Wash your hands often with soap and water for about 20 seconds, or use an alcohol-based hand sanitizer. Avoid touching your eyes, nose and mouth. Clean and disinfect surfaces and objects that may be contaminated with germs. When you are sick, stay home and keep your distance from others. When coughing or sneezing, cover your mouth and nose with your sleeve, or use a tissue and dispose of it immediately.
