When your sick with the flu, your body builds up a defense by making antibodies against it. The flu virus spreads through air when a person coughs, sneezes, or speaks. Its important to treat the flu seriously because it can lead to other viruses such as pneumonia and other life-threatening complications.
For the most part it appears in infants, senior citizens, and people with long term health problems. People with the flu may not know but they are actually contagious from a day before they feel sick. It would usually be one week for adults and two weeks for young kids.
Anyone at any age can have serious complications with the flu but those at high risk are people over 50 years old, children between 6 months and 2 years, women more than 3 months pregnant the flu season, anyone living in a long-term care facility, and anyone with chronic heart, lung or kidney conditions, diabetes, or weakened immune system. Transcript: How the microscope is important to the flu virus?
The microscope was the tool that discovered the flu virus. If it weren't for the microscope we wouldn't know about the flu virus or the vaccine. Without the Discovery Without the discovery of the flu virus there would be no preventions like the vaccine.
Symptoms Immune system Some symptoms of the virus are chills, fever, muscle ache, cough, congestion, runny nose, headaches or fatigue. Why is it so important it was discovered? Your immune system cannot reconize the new form of the virus so your body cannot defend against it. This discovery got a lot of people cured from the flu. It helped the environment by not having the flu spreading across the region.
Changing Microscope plays a role in the discovery of the Flu Virus! Vaccine In the Vaccine The flu changes every year into a new form, which is why we get a new flu vaccine every year. Everyone 6 months or older should get a vaccine every season to protect themself from the flu. What is in the vaccine is the flu virus that has been inactive and therefore not infectious.
Transcript: The symptoms of the flu include a fever of F or higher fever, a cough or sore throat, chills, fatigue, a runny or stuffy nose, headaches, nausea, vomiting, and diarrhea. No, none of these symptoms are particularity The flu is a chronic disease The flu is non lethal Flu Virus Transmission Influenza virus types A, B and C is the causative agent, which is a virus. Transcript: Flu By: Olivia Knight Influenza Flu How you get it You get the flu by a viruses spread through tiny droplets in the air that are released when a sick person sneezes, coughs, or blows their nose.
You can get sick if you touch your nose, eyes, or mouth after you have touched something contaminated by the virus, for exaple a toy, countertop, or doorknob. Influenza vaccine.
Influenza vaccines, also known as flu shots or flu jabs, are vaccines that protect against infection by influenza viruses. A new version of the vaccine is developed twice a year, as the influenza virus rapidly changes.
Don't worry Flu When you cough it can be dry. Your whole body chills, dehydration, fatigue, fever, flushing, loss of appetite, body ache, or sweating Your nose is congested, runny nose, or sneezing Also can have chest pressure, head congestion, headache, nausea, shortness of breath, sore throat, or swollen lymph nodes.
Sytopms that you have, when having the flu. Also Also can have chest pressure, head congestion, headache, nausea, shortness of breath, sore throat, or swollen lymph nodes. While it is possible for the flu itself to cause death due to serious breathing problems and severe dehydration Can you die? Double click to edit Pictures Influenza was discovered not by a direct study of the disease in humans, but rather from studies on animal diseases.
In , J. Koen, a veterinarian, observed a disease in pigs. How did we figure out what the flu was? Who discovered the flu? Influenza Flu was discovered by J. Koen in , Koen was a veterinarian. How was it discovered Influenza was discovered not by a direct study of the disease in humans, but from studies on animal diseases Pigs. Subtopic 2 First of all you need to get the flu shot. Transcript: Incubation Period The flu spreads through air When a person who has the virus sneezes or cough the virus is roaming the air to find a victim Steve People carrying the virus can be contagious 1 day before any symptoms appear Treatment Flu is the common name for Influenza It's a virus that infects the respiratory system Video Pathogen Prevention Sources A higher fever or feeling feverish.

Influenza PowerPoint Presentation. About This Presentation Follow. Fever, chills, headache, aches and pains throughout the body, sore throat which may lead to bronchitis or pneumonia. Vomiting and diarrhoea may also occur.
Many deaths have been attributed to influenza Slide 3 - Influenza Pandemics A pandemic is a world wide spread of infection occurring in many countries simultaneously. Flu pandemics occur approximately every thirty years. Flu pandemics occur because a new strain of the virus emerges for which people have no immunity and there are no vaccines available. Slide 4 - Pandemics New flu viruses occur due to mutation Mutation occurs because different strains of influenza virus can exchange genes by infecting different animals Avian influenza viruses can exchange genes with human influenza viruses creating hybrid strains Slide 5 - - pandemic This killed between 20 — 40 million people Face masks were worn but provided little protection against infection Slide 6 - Cause The cause of influenza is the influenza virus.
Influenza A, B and C viruses are found Influenza A viruses are associated with serious illness and pandemics Slide 7 - Influenza virus The flu virus is an RNA virus The genome codes for five viral proteins and is made of eight fragments. Haemagglutinin attaches the virus to cells and allows the viral envelope to fuse with the cell membrane and enter cells.
Neuraminidase — has a mushroom shape, its role is to allow the release of viruses to infect other cells Slide 9 - HN terminolgy H refers to Haemagglutinin types and each is given a number H1, H2 etc, Neuraminidase is designated N and different forms are available as well e.
H5N1 avian and H1N1. Reservoirs of infection are primarily humans, but birds and pigs can act as reservoirs. The multiple host status makes for mixing of flu types.
Slide 13 - Prevention Public education campaigns are used to reduce infection rates Isolation of infected people is desirable but not always practical Immunisation Slide 14 - Immunisation Vaccines are offered to people aged 65 or over Note: Currently this group has some immunity and are not being targeted Clinically at risk groups — asthmatics, immuno-compromised patients, diabetics, people with chronic respiratory disease.
Prevention is better than cure! Avoid contact with infected people. Read how the population of Eyam avoided spreading the plague!

Many deaths have been attributed to influenza. Slide 3 -. Influenza Pandemics A pandemic is a world wide spread of infection occurring in many countries simultaneously. About two weeks after vaccination, antibodies develop that protect against influenza virus infection. Flu vaccines will not protect against flu-like illnesses caused by non-influenza viruses. The seasonal flu vaccine protects against the three influenza viruses that research suggests will be most common. Want to know more symptoms?
How does it Spread? Well, here's some basic facts for you all :. Staff, Mayo Clinic. National Library of Medicine. Centers for Disease Control and Prevention, 29 June What is Influenza Caused by? Scientists believe that flu pandemics happen about 2 or 3 times a century. Pigs can become infected with influenza strains that can infect three different species; pigs, birds and humans.
The Influenza virus is ranked the sixth leading cause of death among Americans. Fever over degrees Fahrenheit or feeling chills Aching muscles, commonly in the back, arms, or legs Headache Dry cough Fatigue general feeling of sickness and weakness Loss of appetite Nasal congestion Runny nose dry or sore throat By: Jessica Huynh Veronica Astorga P.
The Prognosis for the Patient The Future of This Disease: The influenza is diagnosed by the appearance of specific signs and symptoms of the influenza. It can be confirmed through laboratory testing of throat specimens or blood samples. Pictures How the Influenza Virus Can Be Treated: People who have influenza recover completely within one or two weeks, but for other people, it can develop life-treating problems, like cardiac complications, Reye's syndrome, and Gullain Barre Syndrome.
The future of the Influenza virus is how there will be another human Influenza pandemic. The Influenza virus has a possible chance that it will emerge from the Eurasian aquatic bird reservoirs. It also involves with the classification of the humans and the avian strains, with the growth of mutations that would allow increase the pathogenicity among humans. The History of Influenza It can be prevented by getting annual vaccinations,which is the most effective.
Typically, influenza is transmitted through the air by coughs or sneezes, creating aerosols containing the virus. Influenza can also be transmitted by direct contact with bird droppings or nasal secretions, or through contact with contaminated surfaces.
Airborne aerosols have been thought to cause most infections, although which means of transmission is most important is not absolutely clear. Influenza viruses can be inactivated by sunlight, disinfectants and detergents. As the virus can be inactivated by soap, frequent hand washing reduces the risk of infection. Influenza spreads around the world in seasonal epidemics, resulting in the deaths of between , and , people every year up to millions in some pandemic years.
On average 41, people died each year in the United States between and from influenza. Influenza viruses spread in tiny liquid caused by coughing and sneezing. They spread from person to person.
Sometimes people become infected by touching something that was recently touched with the virus and then touching their mouth or nose. Most adults may be able to infect others beginning one day before they show symptoms and up to five days after becoming sick.
How Influenza Is Spreaded Influenza A; Influenza B Influenza viruses spread through the air, most often when an infected person sneezes, coughs, or speaks. Influenza is highly contagious and is easily spread from person to person by droplets from the nose or throat of an infected person. It spreads when infected persons cough, sneeze, or even talk around others. You can get the flu simply by touching a surface like a telephone or doorknob that has been contaminated by a touch from someone who has the flu.
The viruses can pass through the air and enter your body through your nose or mouth. If you have touched a contaminated surface, they can pass from your hand to your nose or mouth. History of Influenza. It then establishes itself within the lungs and the respiratory tract.
The respiratory tract then becomes the main target for infections, especially for respiratory bacterial infections. Immunosuppression then occurs rendering the immune system to become temporarily deficient. Influenza virus can infect different cells in the upper and lower respiratory tracts influenza particles magnified ,x Pattern and Growth Influenza virus invades across the epithelial surfaces of the respiratory tract.
Came from Mexico in April symptoms are close to Seasonal Flu; only lab tests can determine whether or not youhave contracted the disease How does it effect the body?
