influenza, flu, grippenoun
an acute febrile highly contagious viral disease
An epidemic viral infectious disease characterized by acute nasal catarrh, or by inflammation of the throat or the bronchi, and usually accompanied by fever and general weakness; also called grippe. It is caused by several forms of RNA virus which mutate readily and thereby render vaccines prepared against older forms ineffective, often requiring a new form of vaccine for each new outbreak.
An acute contagious disease of the upper airways and lungs, caused by a virus, which rapidly spreads around the world in seasonal epidemics.
Etymology: From influenza, from influentia.
Influenza, commonly known as "the flu", is an infectious disease caused by influenza viruses. Symptoms range from mild to severe and often include fever, runny nose, sore throat, muscle pain, headache, coughing, and fatigue. These symptoms begin from one to four days after exposure to the virus (typically two days) and last for about 2–8 days. Diarrhea and vomiting can occur, particularly in children. Influenza may progress to pneumonia, which can be caused by the virus or by a subsequent bacterial infection. Other complications of infection include acute respiratory distress syndrome, meningitis, encephalitis, and worsening of pre-existing health problems such as asthma and cardiovascular disease. There are four types of influenza virus, termed influenza viruses A, B, C, and D. Aquatic birds are the primary source of Influenza A virus (IAV), which is also widespread in various mammals, including humans and pigs. Influenza B virus (IBV) and Influenza C virus (ICV) primarily infect humans, and Influenza D virus (IDV) is found in cattle and pigs. IAV and IBV circulate in humans and cause seasonal epidemics, and ICV causes a mild infection, primarily in children. IDV can infect humans but is not known to cause illness. In humans, influenza viruses are primarily transmitted through respiratory droplets produced from coughing and sneezing. Transmission through aerosols and intermediate objects and surfaces contaminated by the virus also occur. Frequent hand washing and covering one's mouth and nose when coughing and sneezing reduce transmission. Annual vaccination can help to provide protection against influenza. Influenza viruses, particularly IAV, evolve quickly, so flu vaccines are updated regularly to match which influenza strains are in circulation. Vaccines currently in use provide protection against IAV subtypes H1N1 and H3N2 and one or two IBV subtypes. Influenza infection is diagnosed with laboratory methods such as antibody or antigen tests and a polymerase chain reaction (PCR) to identify viral nucleic acid. The disease can be treated with supportive measures and, in severe cases, with antiviral drugs such as oseltamivir. In healthy individuals, influenza is typically self-limiting and rarely fatal, but it can be deadly in high-risk groups. In a typical year, 5–15% of the population contracts influenza. There are 3–5 million severe cases annually, with up to 650,000 respiratory-related deaths globally each year. Deaths most commonly occur in high-risk groups, including young children, the elderly, and people with chronic health conditions. In temperate regions of the world, the number of influenza cases peaks during winter, whereas in the tropics influenza can occur year-round. Since the late 1800s, large outbreaks of novel influenza strains that spread globally, called pandemics, have occurred every 10–50 years. Five flu pandemics have occurred since 1900: the Spanish flu in 1918–1920, which was the most severe flu pandemic, the Asian flu in 1957, the Hong Kong flu in 1968, the Russian flu in 1977, and the swine flu pandemic in 2009.
Influenza, also known as the flu, is a highly contagious viral infection of the respiratory system that affects the throat, lungs and nose. It is caused by the influenza virus and is typically spread via droplets when an infected person coughs or sneezes, or by touching surfaces contaminated by the virus. Symptoms often include fever, cough, sore throat, body aches, fatigue, and chills. There are different strains of the influenza virus, with Influenza A and B causing the majority of human cases. Vaccinations are available as a preventative measure.

Etymology: [It. influenza influence, an epidemic formerly attributed by astrologers to the influence of the heavenly bodies, influenza. See Influence.]
Influenza, commonly known as "the flu", is an infectious disease of birds and mammals caused by RNA viruses of the family Orthomyxoviridae, the influenza viruses. The most common symptoms are chills, fever, runny nose, sore throat, muscle pains, headache, coughing, weakness/fatigue and general discomfort. Although it is often confused with other influenza-like illnesses, especially the common cold, influenza is a more severe disease caused by a different type of virus. Influenza may produce nausea and vomiting, particularly in children, but these symptoms are more common in the unrelated gastroenteritis, which is sometimes inaccurately referred to as "stomach flu" or "24-hour flu". Flu can occasionally lead to pneumonia, either direct viral pneumonia or secondary bacterial pneumonia, even for persons who are usually very healthy. In particular it is a warning sign if a child seems to be getting better and then relapses with a high fever as this relapse may be bacterial pneumonia. Another warning sign is if the person starts to have trouble breathing. 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.
Chambers 20th Century Dictionary
in-flōō-en′za, n. a severe epidemic catarrh, accompanied with weakening fever. [It.,—L., a by-form of influence.]
The Nuttall Encyclopedia
an epidemic disease, closely resembles, but is quite distinct from, cold in the head. It is characterised by early and marked debility and depression; though usually of short duration, attacks must not be disregarded; fatal results often ensue on carelessness. Convalescence is slow, and complications may ensue. The cause of the malady is obscure; sporadic cases always occur, but from time to time great epidemics of this disease have travelled westward over the world. Their movement seems to depend on atmospheric conditions, but is independent of the season of the year and often contrary to the direction of the wind. Visitations occurred in Britain in 1837-38, 1847-48, and 1889-91.

Often influenza B is more likely to cause gastrointestinal symptoms than influenza A, though both can in young children, some parents don't recognize these symptoms as part of influenza... which may delay thinking of influenza and delay treatment.
This is the first mother to be diagnosed with influenza and corona in Beilinson. We treated her with a drug combination that targets both corona and flu, we are seeing more and more morbidity of influenza among the maternity population, along with cases of corona that mainly occur in women not vaccinated against corona and influenza.
The flu vaccine will prevent influenza virus and the influenza virus only, certainly we see a lot of mixed respiratory virus infections in our hospital. We'll see often two viruses that are infecting at the same time. ... That makes it all the more important that you get your flu vaccine.
We need to increase public understanding of the need for MCMs such as a pan-influenza or pan-coronavirus vaccine. A key driver is the media, and the economics follow the hype. We need to use that hype to our advantage to get to the real issues. Investors will respond if they see profit at the end of process.
In our paper, we replicated experimentally in monkeys a situation that [was] similar to the 2009 influenza pandemic, where a new strain of influenza unexpectedly emerged and current vaccines offered little or no protection, we vaccinated the monkeys with the same antigens included in the inactivated vaccine that year, but then also added, via our DNA vaccine, the genetic code for conserved influenza antigens. When we challenged the monkeys with the 2009 pandemic strain of influenza, we saw significant protection in the group that got the vaccine. They experienced only a transient low infection that was quickly cleared, when compared to the group that didn’t get the vaccine.
