The flu is a super-contagious virus that can make you feel miserable and unable to get out and do things for usually about a week or more.I have known people who have had it this year and it’s been very bad. Doctors call it influenza. It’s symptoms are usually more serious than the sneezes and a stuffy nose that you tend to get from a common cold. You may have a high fever, headache and muscle aches, cough, sore throat, and tiredness. Most people who get the flu will have mild illness, will not need medical care or antiviral drugs, and will recover in less than two weeks. Some people, however, are more likely to get flu complications that can result in hospitalization and sometimes death. Pneumonia, bronchitis, sinus infections and ear infections are examples of flu-related complications.
The flu also can make chronic health problems worse. For example, people with asthma may experience asthma attacks while they have the flu, and people with chronic congestive heart failure may experience a worsening of this

Added to those scary stats, the World Health Organization estimates that annual flu epidemics result in about 3 to 5 million cases of severe illness globally and 290,000 to 650,000 deaths. Author Susan Scutti in 2018 said “Influenza and its complications disproportionately affect people who are 65 and older. They account for 80% of the deaths," said Dr. William Schaffner, an infectious disease specialist at Vanderbilt University.” You can catch the flu when someone who has it sneezes or coughs, sending virus-filled droplets into the air that you breathe in. You can also get it if you touch somewhere that the virus landed and then touch your mouth, nose, or eyes. Flu is more common in winter because people spend more time in close contact with each other, so the virus spreads more
As you know autoimmune diseases are your immune auto-generate antibodies against cells of your body. In here, I don’t tell physiology of autoimmune diseases but I will tell one of most autoimmune diseases that is immune fertility disease. Researchers at the University of Virginia Health System have found a new human protein, radical radial spoke protein 44 (RSP44) in July, 2007. RSP44 is antigen can be found in all men, residing in the sperm tail at the center of a structure known as the axoneme. Antigens can only stimulate antibody production when they come in contact with components of the blood. Under normal conditions, blood and sperm do not mix. Direct contact between the two is prevented by a cellular structure in the testes called
The Influenza virus is a unique respiratory viral disease that can have serious economic and social disruption to society. The virus is airborne transmitted through droplets release by coughing or sneezing from an infected person or by touching infected surfaces. Symptoms range from mild to severe and may even result in death. People with the virus usually experience fever, headache, shivering, muscle pain and cough, which can lead to more severe respiratory illness such as pneumonia. People most susceptible to the flu virus are elderly individuals and young children as well as anyone whose health or immune system has been compromise. The most effective way to counteract the influenza virus is to get the flu vaccine which is available by shots or nasal spray before the flu season as well as practicing safe hygiene. (CDC, 2013)
The influenza or flu pandemic of 1918 to 1919, the deadliest in modern history, infected an estimated 500 million people worldwide–about one-third of the planet’s population at the time–and estimates place the number of victims anywhere from 25 to 100 million. More than 25 percent of the U.S. population became sick, and some 675,000 Americans died during the pandemic. The 1918 flu was first observed in Europe, the U.S. and parts of Asia before swiftly spreading around the world. Surprisingly, many flu victims were young, otherwise healthy adults. At the time, there were no effective drugs or vaccines to treat this killer flu strain or prevent its spread. In the U.S., citizens were ordered to wear masks, and schools, theaters and other public
The epidemic began at around the end of the first World War and was the most devastating epidemic in recorded world history. Some symptoms of the influenza include muscle pains, sore throat, headache, fever, glandular disturbances, eye aberrations, heart action slowing, and depression of all bodily functions and reactions. The flu is highly contagious and spreads easily whenever an infected person coughs, sneezes or talks. This global disaster was nicknamed the “Spanish Flu,” or “La Grippe.” The nickname of the Spanish Flu came from one of the earliest countries to be hit hard by influenza: eight million people in Spain were killed in the May of 1918.
The influenza virus is most commonly spread from person to person by coughing or sneezing. The virus can also be spread by touching an object that was recently contaminated. Then accidently touching their mouth or
Influenza is a major public health problem which has outbreaks all over the world. Resulting in considerable sickness and death rates. Furthermore, it is a highly infectious airborne disease and is caused by the influenza virus. Influenza is transmitted easily from one person to another person, which has a great impact on society. When a member of society becomes sick, it is more prone to spread to other people.
Influenza is very contagious and spreads rapidly from person to person. Influenza causes worldwide yearly epidemics. According to World Health organization Influenza affects 5-15% world’s population and resulting in 500,000 deaths yearly. Ottenberg stated that, in United States, an average of 200,000 were hospitalized and 36,000 died each year from influenza complications. Influenza is the sixth leading cause of death among US adults and is related to 1 in 20 death in persons older than 65 years. Disease control and prevention estimates indicate that infections like H1N1 which is one of the types of influenza, have resulted in an estimated 42 to 86 million cases and 8520 to 17620 deaths. As I mentioned earlier that infections like influenza are very contagious, they can spread easily from hcw to Patient and back to hcw. The most efficient and effective method of preventing influenza infection is vaccination(The best way to prevent influenza is with annual vaccination).(Sullivan,2010) (Gregory,Tosh &Jacobson, 2005). Motivated by a desire to actively avoid illness Influenza may increase the risk for death in people with existing heart, lung, or circulation disorders. In fact, the higher than average number of winter deaths in people with heart disease may be due only to the occurrence of influenza during those months.Vaccination provides immunity to fight against infection.To increase resistance to harm by modifying the environment to minimize preventable illness (NEED TO CHANGE WORDING)
The influenza pandemic of 1918-1919 killed more people than the Great War, known today as World War I (WWI), at somewhere between twenty and forty million people. (1) Influenza is a virus that appeared in 1918 and caused a pandemic. It made an enormous impact that is still significant to the world today. It has pushed scientists to make advancements in the medicine and vaccination industry that continue to grow each and every day. Influenza may be a horrible thing, but without it we wouldn’t be where we are today.
Medical officials agree that one of the characteristic features of the influenza is its air-born infectivity. "One case to-day may mean a hundred to-morrow and thousands within a week," according to the chief medical officer of the Local Government Board. To protect oneself against the infectious illness that can spread without direct contact with the sick, it is recommended that people situate themselves in well-ventilated rooms. However, once you have contracted the disease, you are to quarantine yourself in an isolated home.5 Other symptoms of influenza include extreme exhaustion, aching limbs, headaches and sometimes, inflammation of nasal mucous membranes.6
Influenza is defined as an acute, commonly epidemic disease, occurring in several forms, caused by numerous rapidly mutating viral strains and characterized by respiratory symptoms and general prostration. Spanish flu was more than just a normal epidemic, it was a pandemic. Epidemics affect many people at the same time in areas where the disease doesn’t normally occur. A pandemic is an epidemic on a national, international, or global scale. The Spanish flu was different from the seasonal flu in one especially frightening way, there was an unusually high death rate among healthy adults aged 15 to 34 and lowered the life expectancy by more than ten years. Such a high death rate has not occurred in this age group in and epidemic prior to or since the Spanish flu pandemic of 1918. (Tumpey, 2005)

Typically, the majority of those who die as a result of the flu are the elderly, and children. Under normal circumstances, this leaves the majority of the working class intact, and any major economic impact is spared. However, the 1918 flu epidemic is unique in that the majority of those who died were of working ages, between 15 and 50. Also, males were disproportionately more likely to die due to flu-related causes. During this time period, men dominated the workforce.
The swine influenza or swine flu is a respiratory disease in pigs that is caused by the type A influenza viruses. These viruses are referred to as swine flu viruses but scientifically the main virus is called the swine triple reassortant (tr) H1N1 influenza virus. When the viruses infect humans they are called variant viruses. This infection has been caused in humans mainly by the H1N1v virus in the United States. The H1N1 virus originates in animals due to improper conditions and the food they ingest. The virus stays in latency form, thus harmless to the respective animal. The longer the animals survive the more likely the virus is to develop and strengthen making it immune to vaccines. The virus reproduced through the lytic cycle. The virus injects its own nucleic acids into a host cell and then they form a circle in the center of the cell. Rather than copying its own nucleic acids, the cell will copy the viral acids. The copies of viral acids then organize themselves as viruses inside of the cell. The membrane will eventually split leaving the viruses free to infect other cells.
The Flu is the common name influenza which is a virus that attacks the respiratory system. The flu virus releases its genetic information into the cells nucleus to replicate itself. When the cell dies, those copies are released and they affect other cells throughout the rest of the body. With that happening the virus weakens the immune system. 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.
