Where does influenza circulate when it is not infecting humans?
Can't It hide away in your cells for a while before it decides to infect you?
Does influenza A virus infect turtles?
No. Most viruses target certain cells. In the case of influenza A, some mammals (including humans) and some birds have been infected.
What is the pathophysiology of influenza ah1n1?
Influenza A(H1N1) virus infects the respiratory tract, leading to inflammation and damage of respiratory epithelial cells. This triggers an immune response resulting in symptoms like fever, cough, and body aches. Severe cases can progress to pneumonia and acute respiratory distress syndrome (ARDS).
What is the host cell of Influenza?
The host cell of the influenza virus is primarily a type of epithelial cell found in the respiratory tract of mammals and birds. The virus specifically targets cells in the upper and lower respiratory tracts, utilizing cell surface receptors, such as sialic acid, to gain entry. Once inside, the virus hijacks the host cell's machinery to replicate and produce new viral particles. This process ultimately leads to cell damage and contributes to the symptoms of influenza infection.
What do the 'H' and 'N' stand for in influenza viruses?
hemaglutinin and neuraminidase, two surface glycoproteins of influenza that contribute the the virulence of the disease...
What has the author Mark Charles Outlaw written?
Mark Charles Outlaw has written: 'Neutralization of influenza virus on respiratory epithelial cells'
Why does the bird flu only attack the lower part of the human respiratory system and not the upper respiratory system?
Bird flu primarily targets the lower respiratory system due to the presence of specific receptors in the cells of the trachea and lungs that are more compatible with the virus. These receptors, known as avian-type sialic acid receptors, are more abundant in the lower respiratory tract, allowing the virus to efficiently enter and infect those cells. In contrast, the upper respiratory system has different receptor types that are less suited for avian influenza viruses, which may explain the virus's limited impact in that area.
What parts of the host body which the virus attack?
Viruses can target various parts of the host body depending on their type. For example, respiratory viruses like influenza primarily infect the respiratory tract, including the nose, throat, and lungs. Other viruses, such as HIV, target the immune system by attacking CD4+ T cells, while gastrointestinal viruses like norovirus infect the intestinal lining. Each virus has specific receptors that allow it to enter and replicate within particular cell types.
Are viruses general or specific to the cells that they infect?
viruses are specific to the cells they infect called host cells
A picture of the influenza virus?
I'm unable to display images as I'm a text-based AI. However, the influenza virus is a spherical particle with proteins on its surface that help it infect cells. It contains genetic material in the form of RNA and is known for causing the flu in humans.
Influenza is unicellular or multicellular?
Influenza is not a cell, it is a respiratory disease caused by a type of viruses, called influenza viruses. Viruses are not cells, they are sub-microscopic organisms that are non-living and disease-causing in humans, animals, and plants as well as in some bacteria.
Why does influenza have RNA?
Influenza is an RNA virus because its genetic material is made up of RNA. RNA viruses like influenza are able to mutate more rapidly than DNA viruses, which contributes to the virus's ability to evolve quickly and evade host immunity.
