United States Influenza Statistics By Flu Season
US influenza statistics by flu season. From the Centers for Disease Control and Prevention page called "Disease Burden of Flu": "Each year CDC estimates the burden of influenza in the U.S. CDC uses modeling to estimate the number of flu illnesses, medical visits, hospitalizations, and deaths related to flu that occurred in a given season. The methods used to calculate these estimates are described on CDC’s webpageHow CDC Estimates the Burden of Seasonal Flu in the U.S. Scroll down for table and illustration. The tables below include the latest available years the CDC has provided on their website. Hospitalizations and deaths * UI = uncertainty interval. * Row numbers are static. Other columns are sortable. This allows ranking of any column. * 2019 to 2020 season is a preliminary estimate.

H1N1 Versus H5N1 Pathology
In virology, influenza A virus subtype H1N1 (A/H1N1) is a subtype of influenza A virus. Major outbreaks of H1N1 strains in humans include the Spanish flu, the 1977 Russian flu pandemic and the 2009 swine flu pandemic. It is an orthomyxovirus that contains the glycoproteins hemagglutinin and neuraminidase. For this reason, they are described as H1N1, H1N2 etc., depending on the type of H or N antigens they express with metabolic synergy. Hemagglutinin causes red blood cells to clump together and binds the virus to the infected cell. Neuraminidase is a type of glycoside hydrolase enzyme which helps to move the virus particles through the infected cell and assist in budding from the host cells. Some strains of H1N1 are endemic in humans and cause a small fraction of all influenza-like illness and a small fraction of all seasonal influenza, for instance in 2004–2005. Other strains of H1N1 are endemic in pigs (swine influenza) and in birds (avian influenza). Its size is in di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Influenza Vaccine
Influenza vaccines, also known as flu shots, are vaccines that protect against infection by influenza viruses. New versions of the vaccines are developed twice a year, as the influenza virus rapidly changes. While their effectiveness varies from year to year, most provide modest to high protection against influenza. The United States Centers for Disease Control and Prevention (CDC) estimates that vaccination against influenza reduces sickness, medical visits, hospitalizations, and deaths. Immunized workers who do catch the flu return to work half a day sooner on average. Vaccine effectiveness in those over 65 years old remains uncertain due to a lack of high-quality research. Vaccinating children may protect those around them. Vaccines are an effective means to control outbreaks of many diseases. However, vaccines for respiratory viral infections such as flu are still suboptimal and do not offer broad-spectrum protection. Vaccination against influenza began in the 1930s, with ...

2019–2020 United States Flu Season
The Centers for Disease Control and Prevention (CDC) estimates that, as of April 4, 2020, the 2019–2020 United States flu season had caused 39 million to 56 million flu illnesses, 410,000 to 740,000 hospitalizations and 24,000 to 62,000 deaths. In January 2020, the Director of the National Institute of Allergies and Infectious Diseases, Dr. Anthony Fauci expected the 2019-2020 flu season to be one of the worst in several years, at least as severe as the 2017-2018 season. By the third week in February the seasonal flu was near its peak with over 26 million people sickened, 250,000 hospitalized, and 14,000 who died. Experts said that the flu came in two waves, with a hard impact on children. The season began in October, earlier than usual, with the expected wave of influenza B virus. The number of children who died, 105, was higher in late February than any season for the past ten years with about 67% associated with influenza B viruses. The second wave came with the influx of in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2017–2018 United States Flu Season
The 2017–2018 United States flu season lasted from late 2017 through early 2018. The predominant strain of influenza was H3N2. During the spring months of March–May, influenza B virus became dominant. In all states except Hawaii and Oregon, the distribution of influenza was indicated as widespread, including 32 states that had high flu activity. The flu season was exacerbated by a shortage of IV bags caused by IV bag plant closures in Puerto Rico following Hurricane María. The CDC estimates that 52,000 Americans died due to influenza during the 2017–2018 flu season. Effects The United States Centers for Disease Control and Prevention (CDC) began counting the 2017–2018 "flu season" as October 2017, and by early February 2018, the epidemic was still widespread and increasing overall. By February 2018, the CDC said that the circulating virus strains included both B strains (Yamagata and Victoria), H1N1 and H3N2. On 10 February 2018, ''Bloomberg'' reported that influenza ...

2012–2013 Flu Season
The 2012–2013 flu season was an epidemic flu season in the United States. United States By the week ending 29 December 2012, the CDC reported that 29 U.S. states had high numbers of reports of flu. By 13 January, nearly all U.S. states had experienced elevated influenza levels. In 9 January after the city of Boston received reports of 700 cases of flu and 4 deaths, the city declared a public health emergency. Boston Mayor Thomas Menino said that "people should take the threat of flu seriously" and that people should receive the influenza vaccine and practice health safety. By 7 January 2013, there were 15,000 cases of flu reported in the state of New York. In the previous year's entire flu season, there were only 4,400 cases in the same region. New York Governor Andrew Cuomo declared a Public Health Emergency, relaxing regulations as to whom pharmacists can immunize. Vaccination The U.S. Centers for Disease Control recommends that all persons in the United States receive an ann ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshers' Flu
Freshers' flu is a name commonly given to a battery of illnesses contracted by new students (freshers) during the first few weeks at a university, and colleges of further education in some form; common symptoms include fever, sore throat, severe headache, coughing and general discomfort. The illnesses may or may not include actual flu and is often simply a bad cold. Causes The most likely cause is the convergence of large numbers of people arriving from all over the world; this is a particularly elevated risk due to the COVID-19 pandemic. The poor diet and heavy consumption of alcohol during freshers' week is also reported as a cause for many of the illnesses contracted during this time. "Stress, which may be induced by tiredness, combined with a poor diet, late nights and too much alcohol, can weaken the immune system and be a recipe for ill health. All this can make students and staff working with the students more susceptible to infections within their first weeks of term." I ...

Dog Flu
The dog (''Canis familiaris'' or ''Canis lupus familiaris'') is a domesticated descendant of the wolf. Also called the domestic dog, it is derived from the extinct Pleistocene wolf, and the modern wolf is the dog's nearest living relative. Dogs were the first species to be domesticated by hunter-gatherers over 15,000 years ago before the development of agriculture. Due to their long association with humans, dogs have expanded to a large number of domestic individuals and gained the ability to thrive on a starch-rich diet that would be inadequate for other canids. The dog has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes. Dog breeds vary widely in shape, size, and color. They perform many roles for humans, such as hunting, herding, pulling loads, protection, assisting police and the military, companionship, therapy, and aiding disabled people. Over the millennia, dogs became uniquely adapted to human behavior, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horse Flu
Equine influenza (horse flu) is the disease caused by strains of influenza A that are enzootic in horse species. Equine influenza occurs globally, previously caused by two main strains of virus: equine-1 (H7N7) and equine-2 (H3N8). The OIE now considers H7N7 strains likely to be extinct since these strains have not been isolated for over 20 years. Predominant international circulating H3N8 strains are Florida sublineage of the American lineage; clade 1 predominates in the Americas and clade 2 in Europe. (Elton and Cullinane, 2013; Paillot, 2014; Slater et al., 2013). The disease has a nearly 100% infection rate in an unvaccinated horse population with no prior exposure to the virus. While equine influenza is historically not known to affect humans, impacts of past outbreaks have been devastating due to the economic reliance on horses for communication (postal service), military (cavalry), and general transportation. In modern times, though, the ramifications of equine influenza are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swine Flu
Swine influenza is an infection caused by any of several types of swine influenza viruses. Swine influenza virus (SIV) or swine-origin influenza virus (S-OIV) refers to any strain of the influenza family of viruses that is endemic in pigs. As of 2009, identified SIV strains include influenza C and the subtypes of influenza A known as H1N1, H1N2, H2N1, H3N1, H3N2, and H2N3. Swine influenza virus is common throughout pig populations worldwide. Transmission of the virus from pigs to humans is rare, and does not always lead to human flu, often resulting only in the production of antibodies in the blood. If transmission causes human flu, it is called zoonotic swine flu. People with regular exposure to pigs are at increased risk of swine flu infections. Around the mid-20th century, identification of influenza subtypes was made possible, allowing accurate diagnosis of transmission to humans. Since then, only 50 such transmissions have been confirmed. These strains of swine flu rarel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Flu
Humans (''Homo sapiens'') are the most abundant and widespread species of primate, characterized by bipedalism and exceptional cognitive skills due to a large and complex brain. This has enabled the development of advanced tools, culture, and language. Humans are highly social and tend to live in complex social structures composed of many cooperating and competing groups, from families and kinship networks to political states. Social interactions between humans have established a wide variety of values, social norms, and rituals, which bolster human society. Its intelligence and its desire to understand and influence the environment and to explain and manipulate phenomena have motivated humanity's development of science, philosophy, mythology, religion, and other fields of study. Although some scientists equate the term ''humans'' with all members of the genus ''Homo'', in common usage, it generally refers to ''Homo sapiens'', the only extant member. Anatomically modern huma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
