Key Facts about Influenza (Flu) & Flu Vaccine | Seasonal Influenza (Flu) | CDC - 2 views

  • What is influenza (also called flu)?
  • The flu is a contagious respiratory illness caused by influenza viruses that infect the nose, throat, and lungs. It can cause mild to severe illness, and at times can lead to death. The best way to prevent the flu is by getting a flu vaccine each year.
  • Signs and symptoms of flu
  • ...58 more annotations...
  • People who have the flu often feel some or all of these signs and symptoms:
  • Fever*
  • though this is more common in children than adults.
  • It’s important to note that not everyone with flu will have a fever.
  • How flu spreads
  • Most experts believe that flu viruses spread mainly by droplets made when people with flu cough, sneeze or talk.
  • Period of contagiousness
  • You may be able to pass on the flu to someone else before you know you are sick, as well as while you are sick. Most healthy adults may be able to infect others beginning 1 day before symptoms develop and up to 5 to 7 days after becoming sick.
  • How serious is the flu?
  • Flu is unpredictable and how severe it is can vary widely from one season to the next depending on many things, including:
  • Certain people are at greater risk for serious complications if they get the flu. This includes older people, young children, pregnant women and people with certain health conditions (such as asthma, diabetes, or heart disease).Flu seasons are unpredictable and can be severe. Over a period of 30 years, between 1976 and 2006, estimates of flu-associated deaths in the United States range from a low of about 3,000 to a high of about 49,000 people.
  • Complications of flu can include bacterial pneumonia, ear infections, sinus infections, dehydration, and worsening of chronic medical conditions, such as congestive heart failure, asthma, or diabetes.

  • Prevent seasonal flu: Get vaccinated
  • The single best way to prevent the flu is to get a flu vaccine each season. There are several flu vaccine options for the 2014-2015 flu season.Traditional flu vaccines made to protect against three different flu viruses (called “trivalent” vaccines) are available. In addition, flu vaccines made to protect against four different flu viruses (called “quadrivalent” vaccines) also are available.
  • Trivalent flu vaccine protects against two influenza A viruses (an H1N1 and an H3N2) and an influenza B virus.
  • While seasonal influenza outbreaks can happen as early as October, most of the time influenza activity peaks in January or later. Since it takes about two weeks after vaccination for antibodies to develop in the body that protect against influenza virus infection, it is best that people get vaccinated so they are protected before influenza begins spreading in their community.
  • When to get vaccinated against seasonal flu
  • Yearly flu vaccination should begin soon after flu vaccine is available, and ideally by October. However, getting vaccinated even later can be protective, as long as flu viruses are circulating.
  • The flu is a contagious respiratory illness caused by influenza viruses that infect the nose, throat, and lungs. It can cause mild to severe illness, and at times can lead to death.
  • Less often, a person might also get flu by touching a surface or object that has flu virus on it and then touching their own mouth, eyes or possibly their nose.

  • In the majority of cases flu is not serious -
  • his is more likely if you are elderly or have some other longstanding illness that can undermine your immune system. Your risk of experiencing severe flu complications is higher
  • As flu is caused by a virus, antibiotics won't do any good, unless the flu has led to another illness.
  • Some painkillers, such as aspirin, should not be given to children under 12 (Department of Health, United Kingdom). If you have flu you should: stay at home try to avoid contact with other people keep warm and rest make sure you consume plenty of liquids don't consume alcohol if you are a smoker stop smoking or cut your consumption down as much as you can try to get some food down (eat what you can) if you live alone, tell a relative, friend or neighbor that you have flu. Make sure someone can check in on you and do your shopping
  • In the United States approximately 5% to 20% of the population gets flu,
  • According to the World Health Organization (WHO), in annual influenza epidemics 5% to 15% of the world's population become ill with upper respiratory tract infections.
  • Health experts and government agencies throughout the world say that the single best way to protect yourself from catching flu is to get vaccination every year.

  • The most effective way to prevent influenza is by getting the influenza vaccine (the flu shot or flu nasal spray) and using simple infection control measures such as hand washing. Antiviral medicines can also help prevent infection if you are exposed to the flu.
  •  Because the influenza virus changes (or "mutates") slightly from year to year, you need a new influenza vaccine before each flu season. People should get the flu vaccine soon after it has become available to get the most benefit.
  • People who are vaccinated form antibodies (proteins), which destroy the influenza virus after the person is exposed. It generally takes about two weeks to make these antibodies.
  • Vaccine formulations — The flu vaccine is available in three forms in the United States, as an injection into the muscle, as an injection into the skin, and as a nasal spray
  • The injection of the flu vaccine into the muscle (regular flu shot) is approved for adults and children 6 months and older. In older adults, a high-dose version of this vaccine works a little better than the standard-dose version;
  • The injection of flu vaccine into the skin in what is called an intradermal injection is approved for adults aged 18 to 64 years.
  • The nasal spray is approved only for healthy children age 2 years and older and healthy adults up to 49 years. In 2014, the Advisory Committee on Immunization Practices recommended the nasal spray instead of the regular flu shot for healthy children 2 to 8 years of age when it is immediately available.
  • Vaccine side effects — People who get the vaccine as an injection (either into muscle or skin) can have reactions at the injection site. Intramuscular injections can cause redness, swelling, and/or soreness at the site. Intradermal injections can cause redness, swelling, and/or itching. The high-dose intramuscular vaccine and the intradermal vaccine are more likely to cause local reactions than the standard-dose intramuscular vaccine
  • Antiviral medicines can help to reduce the chances of developing the flu after being exposed to someone who is infected. These medicines can also be used in certain people who are at risk for developing complications from the flu and who cannot receive the flu vaccine.

  • Getting the influenza vaccine is the most effective way to reduce the chance of becoming infected with the flu. People who get the influenza vaccine have a lower chance of illness and death from influenza compared with people who are not vaccinated.

  • 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.
  • the sheer volume of deaths to be counted; not everyone that dies with an influenza-like illness is tested for influenza; and influenza-associated deaths are often a result of complications secondary to underlying medical problems, and this may be difficult to sort out.

  • When viruses change in that way, they are said to be “drifted” viruses.

  • g of flu
  • 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.

  • 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.

Epidemiology of Avian Influenza - 0 views

  • Avian influenza (AI) is caused by specified viruses that are members of the family Orthomyxoviridae and placed in the genus influenzavirus A
  • There are three influenza genera - A, B and C;
  • Domestic fowl, ducks, geese, turkeys, guinea fowl, quail and pheasants are susceptible.
  • ...7 more annotations...
  • Disease outbreaks occur most frequently in domestic fowl and turkeys. A particular isolate may produce severe disease in turkeys but not in chickens or any other avian species. Therefore, it would be impossible to generalize on the host range for avian influenza, for it will likely vary with the isolate. This assumption is supported by reports of farm outbreaks where only a single avian species of several species present on the farm became infected. Many species of wild birds particularly water birds and seabirds - are also susceptible, but infections in these birds are generally sub-clinical.
  • athogenic strains could emerge and cause disease in domestic poultry in any country at any time without warning. In fact, outbreaks have occurred at irregular intervals on all continents.
  • he most serious outbreaks in recent times have been reported in Hong Kong 1997-1998 and 2003, Chile 2002, The Netherlands 2003 and South East Asia 2004-2006.
  • he incubation period is 3 to 5 days in general but may be longer. Maximal incubation period is 21 days as defined by the OIE Terrestrial Animal Health Code.
  • Inactivated quality assured oil-emulsion vaccines have been demonstrated to be effective in reducing mortality, preventing disease, or both, in chickens and turkeys. These vaccines, however, may not prevent infection in some individual birds, and if infected could shed virulent virus. Nevertheless, the amount virus shed is considerable less than that of non-vaccinated and infected birds. It is imperative that the circulating antigenic avian influenza virus is known and the vaccine represent this antigenic strain, since there is no cross-protection among the 15 known HA subtypes.
  • Birds that die of peracute disease may show minimal gross lesions, consisting of dehydration and congestion of viscera and muscles.
  • The following diseases must be considered in the differential diagnosis of virulent AI: Other diseases causing sudden high mortality Newcastle disease infectious laryngotracheitis duck plague acute poisonings

Influenza (Flu) - 0 views

  • Influenza, commonly known as "the flu," is a highly contagious viral infection of the respiratory tract
  • Although flu vaccine is recommended for everyone aged 6 months or older, in times when the vaccine is in short supply, certain people need it more than others. The Centers for Disease Control and Prevention (CDC) often will recommend that certain high-risk groups be given priority when flu shot supplies are limited. Call your doctor or local public health department about vaccine availability in your area.
  • Some kids with the flu need to be hospitalized.
  • ...22 more annotations...
  • flu season runs from October to May
  • The vaccine prevents against infection from the flu viruses that researchers predict will be most common in the upcoming year
  • most cases occurring between late December and early March
  • For a severely ill child or one with other special circumstances, a doctor may prescribe an antiviral medicine that can decrease the duration of illness by 1-2 days and prevent potential complications of the flu
  • If an antiviral medication is prescribed, be sure to discuss any possible side effects with your doctor.
  • Given as an injection, the flu shot contains killed flu viruses that will not cause the flu, but will prepare the body to fight off infection from that particular type of live flu virus if someone comes into contact with it.
  • Symptoms, which usually begin about 2 days after exposure to the virus, can include: fever chills headache muscle aches dizziness loss of appetite tiredness cough sore throat runny nose nausea or vomiting weakness ear pain diarrhe
  • all kids 6 months through 4 years old anyone 65 years and older all women who are pregnant, are considering pregnancy, have recently given birth, or are breastfeeding during flu season anyone whose immune system is weakened from medications or illnesses (like HIV infection) residents of long-term care facilities, such as nursing homes any adult or child with chronic medical conditions, such as asthma kids or teens who take aspirin regularly and are at risk for developing Reye syndrome if they get the flu all health care personnel caregivers or household contacts of anyone in a high-risk group (like children younger than 5 years old, especially those younger than 6 months, and those with high-risk conditions) Native Americans and Alaskan natives
  • The nasal mist contains weakened live flu viruses that cannot cause the severe symptoms typically associated with the flu, but can cause some mild symptoms
  • drink lots of fluids to prevent dehydration get plenty of sleep and take it easy take acetaminophen or ibuprofen to relieve fever and aches (do not give aspirin to children or teens as it may cause a rare but serious illness called Reye syndrome) wear layers, since the flu often makes them cold one minute and hot the next (wearing layers — like a T-shirt, sweatshirt, and robe — makes it easy to add or subtract clothes as needed)
  • Kids who are sick should stay home from school and childcare until they are without fever for at least 24 hours without the use of a fever-reducing medicine.
  • So to have the best protection against the flu, it's important to get the vaccine every year.
  • It is given in places like hospitals, clinics, community centers, pharmacies, doctor's offices, and schools
  • infants under 6 months old anyone who's ever had a severe reaction to a flu vaccination anyone with Guillain-Barré syndrome (a rare condition that affects the immune system and nerves)
  • After 5 days, fever and other symptoms have usually disappeared, but a cough and weakness may continue
  • Call the doctor if your child:
  • has flu symptoms has a high fever, or fever with a rash has trouble breathing or rapid breathing has bluish skin color is not drinking enough fluids seems very sleepy or lethargic seems confused has flu symptoms that get better, but then get worse
  • All symptoms are usually gone within a week or two
  • The flu is contagious, spread by virus-infected droplets that are coughed or sneezed into the air
  • The flu usually occurs in small outbreaks, but epidemics — when the illness spreads rapidly and affects many people in an area at the same time — tend to occur every few years. Epidemics often peak within 2 or 3 weeks after the first cases occur.
  • Preventing the Flu From Spreading There's no guaranteed way — including being vaccinated — to prevent anyone from getting the flu
  • Wash your hands thoroughly and frequently with soap, especially after using the bathroom, after coughing or sneezing, and before eating. Never pick up used tissues. Never share cups and eating utensils. Stay home from work or school when you're sick with the flu. Cover your mouth and nose with a tissue when you cough or sneeze, then put it in the trash. If a tissue isn't available, cough or sneeze into your upper arm, not into your hands.

  • ...12 more annotations...
  • Influenza type A viruses can infect people, as well as birds, pigs, horses, and other animals
  • There are two subtypes of influenza A viruses found in and circulating among humans: regular H1N1 and H3N2. These two subtypes are included in the seasonal flu vaccine each year.
  • Influenza Type B viruses are usually found only in humans
  • Influenza B viruses can cause illness among humans, but in general are associated with less severe contagious disease than influenza A viruses.
  • Influenza Type C viruses cause mild illness in humans. Influenza C cases occur much less frequently than A and B and are not typically included in the seasonal flu vaccine
  • This new flu virus, also known as swine flu, is a subtype of influenza Type A. It has been spreading quickly around the world. It causes illness similar to seasonal flu.
  • Avian influenza, or bird flu, is also a subtype of influenza Type A viruses
  • Each year around 3,000 to 49,000 Americans die from flu and its complications. For healthy children and adults, influenza is typically a moderately severe illness.  Most people are back on their feet within a week.  Certain groups of people are more susceptible to complications related to the flu and are considered "high risk
  • highly contagious in birds, it does not usually infect humans
  • The best thing to do is to stay home and avoid contact with other people except to get medical care.
  •  If you are considered high risk, it is important to contact your health care provider right away. People at high risk are more likely to suffer from severe complications from the influenza virus.
