Why influenza A and influenza B cause epidemics but influenza C doesn't?
Influenza C viruses are also found in people. They are, however, milder than either type A or B. People generally do not become very ill from the influenza type C viruses. Type C flu viruses do not cause epidemics. Almost all adults have been infected with C but it just doesn't have the ability to cause epidemics and it doesn't fit the term epidemic.
What does the A stand for in Influenza A virus?
The A and B in influenza are simply different types of influenza. * Type A: seasonal epidemics. This sub-type is based on changes in surface antigens hemagglutinin and neuraminidase. In humans subtypes H1-H3 and N1-N2 have circulated since 1918 pandemic (due to H1N1). In the last 3 decades the circulating types have been H3N2 and H1N1. * Type B: sporadic outbreaks (long term care facilities)
Which type of influenza is the worst?
Influenza A is generally considered the worst type due to its ability to cause more severe illness, pandemics, and higher transmission rates compared to Influenza B and C. Influenza A viruses have more genetic variability, allowing them to rapidly evolve and potentially develop resistance to antiviral medications.
What is the genus and species category for influenza?
it is a negative single strand RNA virus of family orthomyxoviridae having four group: influenza A, influenza B, influenza C, and thogoto virus. containing 7to 8 segments of linear rna with a genome length b/w 12,000 to 15,000.
What is the name of the microorginism in influenza?
Influenza is an infectious disease also commonly known as Flu. It’s an acute respiratory infection caused by Influenza Virus A and Virus B. Central BioHub's is an online biospecimen marketplace. It offers high-quality, well-defined influenza disease biospecimens collected from patients suffering from influenza infections. To check more visit our website.
What is the difference between Influenza A and Influenza B?
Influenza A and Influenza B are two different types of flu viruses. Influenza A is more common and can infect both humans and animals, while Influenza B mainly affects humans. Influenza A has more subtypes and can cause more severe outbreaks, while Influenza B typically causes milder illness.
What is the difference between Type B flu viruses and the Swine Flu?
They are different types of influenza viruses. Human "Swine flu" (H1N1/09) is caused by Type A viruses.
What is the difference between the flu A and B viruses?
Influenza A and B viruses are both types of flu viruses that can cause similar symptoms like fever, cough, and body aches. The main difference between them is that influenza A viruses can infect both humans and animals, while influenza B viruses mainly infect humans. Additionally, influenza A viruses have different subtypes, such as H1N1 and H3N2, which can cause more severe outbreaks compared to influenza B viruses.
What is the difference between flu A and flu B?
Influenza A and influenza B are two different types of the flu virus. Influenza A is more common and can infect both humans and animals, while influenza B mainly affects humans. Influenza A has more subtypes and can cause more severe outbreaks, while influenza B typically causes milder symptoms.

What is the difference between Influenza A and Influenza B viruses?
Influenza A and Influenza B viruses are both types of flu viruses that can cause similar symptoms. However, they differ in their genetic makeup and the strains they can produce. Influenza A viruses are more common and can infect a wider range of animals, including humans, birds, and pigs. They are also known to cause more severe outbreaks and pandemics. In contrast, Influenza B viruses mainly infect humans and typically cause milder illness compared to Influenza A.
What are the differences between influenza A and influenza B viruses?
Influenza A and influenza B viruses are both types of the flu, but they have some key differences. Influenza A viruses can infect both humans and animals, while influenza B viruses mainly infect humans. Influenza A viruses are more likely to cause pandemics and have more subtypes, while influenza B viruses have fewer subtypes and typically cause milder illness.

What is influenza type b?
There are four types of influenza viruses: A, B, C and D. Human influenza A and B viruses cause seasonal epidemics of disease almost every winter in the United States. Influenza type C infections generally cause a mild respiratory illness and are not thought to cause epidemics. Influenza D viruses primarily affect cattle and are not known to infect or cause illness in people.A, B and C cause a severe upper respiratory infections. These are more than 'just a cold.'
Why influenza A and influenza B cause epidemics but influenza C doesn't?
Influenza C viruses are also found in people. They are, however, milder than either type A or B. People generally do not become very ill from the influenza type C viruses. Type C flu viruses do not cause epidemics. Almost all adults have been infected with C but it just doesn't have the ability to cause epidemics and it doesn't fit the term epidemic.

What is the difference between Flu A and Flu B?
They are caused by two different kinds of viruses. There are three types of influenza viruses that have been classified according to the types of proteins they have. There are Type A, Type B, and Type C influenza viruses. Type A and B each have many different strains. Type C does not.Type A influenza is one of the more common types we see in the seasonal flu among humans and it is also a very common type that many other animals get. It has subtypes and strains that differ, which is why having one subtype will not give you immunity from all the other subtypes and strains.Type B influenza is also a common type among humans and is found only in humans. It is not divided into subtypes but there are multiple strains.Type C has been found in humans, pigs, and dogs. The symptoms are usually very mild, milder than those of Type A and B influenza viruses, and it typically doesn't cause epidemics. It is not divided into different subtypes or strains.
