Transcript of Influenza

What is influenza? Influenza is a contagious viral infection of the respiratory passages causing fever, severe aching, and catarrh. What are the symptoms of the disease? Is it fatal. INFLUENZA
by: Krista Goodman It's usually referred to as the flu or grippe. What is the cause? And type of pathogen How is it transmitted? - It's a viral infection
- Virus types A, B, and C
- Both virus types A and B are the cause of seasonal outbreaks of the flu
- Type A is found in many different animals
- Type B circulates among humans Its spread from person to person through coughing and sneezing. People may also become infected by touching contaminated surfaces. What body system does it affect? How widespread is it? How many diagnosed each year? At what age do these symptoms develop?How do these symptoms progress? Can the disease be treated? How? Can the disease be prevented? How? What kind of research is being done to learn more about the disease? How was the disease discovered? Who discovered it? Historically significant. Interesting facts: The respiratory system - Washing your hands
- Covering your mouth
- Keeping your body nourished and hydrated
- Get a flu shot
- Keep your home and office sanitary
- Sleep - Over-the-counter medications may relieve some flu symptoms but will not make you less contagious.
- Your health care provider may prescribe antiviral medications to make your illness milder and prevent serious complications.
- Your health care provider may prescribe antibiotics if your flu has progressed to a bacterial infection. - Sensitivities of rapid diagnostic tests are approximately 50-70% when compared with viral culture or reverse transcription polymerase chain reaction (RT-PCR), and specificities of rapid diagnostic tests for influenza are approximately 90-95%.
- Since Oct. 1, there have been 3,710 people hospitalized because of the flu. According to the new report, the proportion of people going to the doctor for flu-like illness from Dec. 30 to Jan. 5 was 4.3 percent, which is higher than normal. Influenza was discovered not by a direct study of the disease in humans, but rather from studies on animal diseases. In 1918, J.S. Koen, a veterinarian, observed a disease in pigs which was believed to be the same disease as the now famous “Spanish” influenza pandemic of 1918. Influenza research involves investigating molecular virology, pathogenesis, host immune responses, genomics, and epidemiology regarding influenza. The main goal of research is to develop influenza countermeasures such as vaccines, therapies and diagnostic tools. -Certain people are at greater risk of serious flu-related complications (including young children, elderly persons, pregnant women and people with certain long-term medical conditions) and this is true both for seasonal flu and novel flu virus infections. (For a full list of people at higher risk of flu-related complications, see People at High Risk of Developing Flu–Related Complications). If you are in a high risk group and develop flu symptoms, it’s best for you to contact your doctor. Remind them about your high risk status for flu. - The cost of treating annual flu epidemics, including lost wages and productivity of workers, is billions of dollars each year in just the United States alone.
-A negative swine flu test doesn’t mean you don’t have the H1N1 virus.
- Flu viruses can live up to 48 hours on hard, nonporous surfaces such as stainless steel and up to 12 hours on cloth and tissues. They can remain infectious for about one week at human body temperature, over 30 days at freezing temperatures, and indefinitely at temperatures below freezing. What is the medical term for influenza and common name? Occasionally influenza can lead to death from influenza-related pneumonia, or from other influenza related complications such as an aggravation of underlying chronic heart and lung disease. so yes it can be fatal to some people. Certain group? - Nursing-home residents (the elderly or disabled)
- Elderly indivisuals
- People with chronic medical conditions
- Other groups such as pregnant women, health care workeres, those with essential functions in society, as well as children from ages 6 months to 2 years.
