Influenza
Purpose: To inform my audience about the Influenza viruses.
Central Idea: To better understand the different types of Influenza viruses that can affect humans. It is important to explore what it is, how it’s spread, who is at risk, and the best protection against it.
I. Introduction
A. Attention Getter: Have you all ever noticed that we get sick more often during the winter months than any other time of year? This can be very frustrating because some of us are traveling to see family for the holidays, and it’s a busier time of year altogether. The reason this happens is because it’s flu season!
B. According to the CDC, Seasonal Influenza, or more commonly known as the flu, is a contagious respiratory illness …show more content…
caused by influenza viruses. It can cause mild to severe illness. Serious outcomes of flu infection can result in hospitalization or death.
C. From the same source, it states that Avian influenza (bird flu) refers to the disease caused by infection with bird flu Type A viruses. These viruses occur naturally among wild aquatic birds worldwide and can infect domestic poultry and other bird and animal species.
D. Swine influenza (swine flu) is a respiratory disease of pigs by type A influenza viruses that regularly cause outbreaks of influenza in pigs.
E. In order to better understand the different influenza viruses that can affect humans, it is important to know how it’s spread, the signs and symptoms, who is at risk, and how to prevent from getting it.
Transition: I’ll begin with Seasonal Influenza
II. Body
A. Seasonal Influenza
1. According to virology.ws, seasonal influenza virus may be transmitted among humans in three ways:
a. By direct contact with infected individuals
b. By contact with contaminated objects (called fomites, such as toys, doorknobs)
c. By inhalation of virus-laden aerosols. Some ways your body produces aerosols are by speaking, singing, normal breathing, coughing and sneezing.
2. Signs and Symptoms
a. 100 degree Fahrenheit or higher fever or feeling feverish (not everyone with the flu has a fever)
b. A cough and/or sore throat
c. A runny or stuffy nose
d. Headaches and/or body aches
e. Chills
f. Fatigue
Nausea, vomiting, and/or diarrhea (most common in children)
3. People Who Are at Risk
a. Children and infants
b. Pregnant women
c. Seniors
d. People with disabilities
e. People with health conditions
f. Travelers and people living abroad
4. There are a couple different ways you can prevent from getting the seasonal flu.
a. Learn the everyday steps you can take to stop the spread of germs and how anti-viral medications can prevent you from getting the flu if you’ve been exposed to a sick person.
b. Vaccination is the best way to protect yourself from the flu. Get information on the current flu vaccine, how and where you can get it, and possible side effects.
Transition: Next I’ll talk about the Bird Flu
B. H5N1 Bird Flu
1. According to flu.gov, human infection with H5N1 is rare. Nearly 650 cases of human cases of H5N1 have been reported from 15 countries since 2003. Most infections occurred after direct or close contact with poultry infected with H5N1. There is no evidence that this virus can spread easily between people.
2. Symptoms of highly pathogenic H5N1 in people can include:
a. Fever and cough
b. Acute respiratory distress
c. Shortness of breath/difficulty breathing
d. Abdominal pain
e. Diarrhea
3. Complications can include:
a. Pneumonia
b. Respiratory failure
c. Shock
d. Altered mental state
e. Seizures
f. Failure of multiple organs
g. Death
4.
The best way to prevent infection is to avoid any contact with sick or dead poultry. This includes:
a. Avoiding visiting live poultry markets that may be infected with H5N1 when traveling.
b. Also, avoid sick people who might have H5N1 virus infection in affected countries.
Transition: The final thing I’ll discuss is the Swine Flu
C. H1N1 Swine Flu
1. The H1N1 virus is currently a seasonal flu found in humans. Although it also circulates in pigs, you cannot get it by eating properly handled and cooked pork or pork products. It spreads between people in the same way the seasonal flu viruses spread.
2. The symptoms of H1N1 are the same as seasonal flu symptoms.
3. According to flu.gov, 2014 is the first season since 2009 that H1N1 has been so predominant in the United States.
4. The best way to prevent the H1N1 flu is to get the seasonal flu vaccine, which protects against the virus.
Transition: In closing….
Conclusion
A. In this speech I have covered the different types of influenza viruses found in humans, how they are transmitted , people they affect, and ways to protect and prevent from getting them.
B. So, before your nose fills up with snot, be smart and go get yourself a flu shot!
