Can you get the flu from being around someone who has it?
People are much more likely to get infected with the flu from being around other sick people than they are from touching virus-laden surfaces.
Person-to-person transmission of the flu can happen when an infected person is talking, coughing, sneezing, or even just breathing near someone else..
What is the regular flu called?
Influenza is a viral infection that attacks your respiratory system — your nose, throat and lungs. Influenza is commonly called the flu, but it’s not the same as stomach “flu” viruses that cause diarrhea and vomiting.
Is influenza A very contagious?
People with flu are most contagious in the first 3-4 days after their illness begins. Some otherwise healthy adults may be able to infect others beginning 1 day before symptoms develop and up to 5 to 7 days after becoming sick.
Where does the influenza virus come from?
Answer: Influenza is a virus that’s spread from person to person. It originates, actually, among birds and other animals such as pigs, and new viral strains of influenza come to this country and to Europe from Southeast Asia.
What makes influenza unique?
Influenza A is also able to drastically alter its genome, because it is capable of undergoing antigenic shift. What this means is that influenza A is capable of undergoing genetic recombination between viral stains. This can, and has, led to major worldwide pandemics.
What is the name of the virus that causes influenza?
There are four types of influenza viruses: A, B, C and D. Human influenza A and B viruses cause seasonal epidemics of disease (known as the flu season) almost every winter in the United States. Influenza A viruses are the only influenza viruses known to cause flu pandemics, i.e., global epidemics of flu disease.
What is the incubation period for influenza virus?
The incubation period of influenza is 2 days long on average but may range from 1 to 4 days in length.
What is Influenza A vs B?
Unlike type A flu viruses, type B flu is found only in humans. Type B flu may cause a less severe reaction than type A flu virus, but occasionally, type B flu can still be extremely harmful. Influenza type B viruses are not classified by subtype and do not cause pandemics.
How long after being exposed to influenza B do symptoms appear?
How soon do symptoms appear? Symptoms of influenza usually appear 1-4 days after exposure. How long can a person spread influenza? Persons are most contagious during the 24 hours before symptoms appear and may be contagious for up to 5 -7 days after getting sick.
Where do viruses go after flu season?
The influenza A virus does not lie dormant during summer but migrates globally and mixes with other viral strains before returning to the Northern Hemisphere as a genetically different virus, according to biologists who say the finding settles a key debate on what the virus does during the summer off season when it is …
Is Flu A or B worse?
Frequently asked questions about Influenza A and B Influenza type A and type B are similar, but type A is overall more prevalent, sometimes more severe, and can cause flu epidemics and pandemics.
What is the causative agent of influenza?
Infectious agent of influenza Influenza virus (types A, B and rarely C) is the causative agent.
Is influenza A human virus?
What is type A influenza? Influenza — also known as the flu — is a contagious viral infection that attacks your respiratory system. Influenza viruses that infect humans can be classified into three main groups: A, B, and C. Type A influenza infection can be serious and cause widespread outbreaks and disease.
Is influenza bacterial or viral?
The flu is a viral infection caused by the influenza virus, a respiratory virus. The common cold is also a viral infection caused by the adenovirus or coronavirus and there are many, many subsets with a lot of variability. That’s why it’s said there’s no cure for the common cold [and] there’s no real vaccine.
