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 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.
Who are the victims of Type A influenza?
Just about anyone who gets the flu. Most of the influenza viruses that cause disease in humans are Type A influenza viruses (but not all). Type A flu viruses are also what cause pandemics in humans.
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.
When diagnosed with the flu what parts of the body are affected?
Influenza, or "flu," is a caused by a virus infecting the respiratory system (nose, throat, bronchial tubes, lungs).
Introduction of ah1n1 virus?
AH1N1 virus, also known as influenza A virus subtype H1N1, is a strain of the influenza virus that causes respiratory illness in humans. It gained global attention during the 2009 flu pandemic and continues to circulate as a seasonal flu virus. Symptoms of AH1N1 infection can range from mild to severe, with the potential for serious complications in certain populations.
How long has rabies has been infecting humans?
The virus has evolved with mankind or say mammals.
What are the different types of influenza viruses?
Influenza viruses are classified into four main types: A, B, C, and D. Influenza A viruses are the most common and can infect both humans and animals, often causing seasonal epidemics. Influenza B viruses primarily affect humans and are generally less severe than A viruses, with limited geographical spread. Influenza C causes mild respiratory illness and is not associated with epidemics, while Influenza D primarily affects cattle and is not known to infect humans.
Is the bird flu a virus or Bacteria?
Influenza A virus H5N1, is known as "bird flu". H5N1, is a subtype of the influenza A virus which can cause illness in humans and animals. A filtered and purified influenza A vaccine for humans is being developed.
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 organism does the influenza infect?
Influenza primarily infects birds and mammals, including humans. It is a virus that affects the respiratory system and can cause symptoms such as fever, cough, and body aches.
Has a new influenza virus called Bat Flu been discovered?
Yes, the Centers for Disease Control and Prevention (CDC) just announced on February 27, 2012 that the first influenza virus found that is capable of infecting bats was just discovered in Guatemala in fruit bats. However, at present this is not a threat to humans and is undergoing extensive study to assure that it does not pose a future human health issue. Preliminary studies do indicate that the genes carried in the new virus would be compatible with the genes in human influenza viruses, but the bat virus would have to undergo significant changes to be able to mutate into a new human virus capable of causing human influenza. To reassort and become a threat to humans, it would first require that a third animal be susceptible to infection by both the new virus and a human influenza virus as well. If the third animal catches the new bat flu and would then at the same time be infected by a human influenza virus, then reassortant into a new virus capable of infecting humans could occur. However, it would require that a single cell of the third host animal would be infected simultaneously with the bat flu virus and a human flu virus. If two flu viruses are inside a host cell at the same tme, then the genetic material inside the two viruses could combine to form a new virus capable of infecting humans. This is how H1N1/09 first developed in pigs (see related question below). A link to the CDC site's article on the new bat virus is provided in the related links section of this question.
