Is influenza restricted to Homo sapiens?
No, there are types of influenza viruses that many different groups of mammals can get infected by, as well as birds (such as the avian/bird flu).
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.
Is the H1N1 bacteria?
H1N1 refers to a subtype of the influenza virus, not a bacteria. Influenza viruses can cause respiratory illness in humans and animals. It is important to note that viruses and bacteria are different types of microorganisms that can cause different types of infections.
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.
How many types of influenza exist?
There are four main types of influenza viruses: A, B, C, and D. Influenza A and B are the most common causes of seasonal flu in humans, while influenza C tends to cause milder respiratory illness. Influenza D primarily affects animals.
What is the scientific name of the pathogen that causes the flu?
The scientific name of the pathogen that causes the flu is Influenza virus. There are different types of influenza viruses, with the main ones being type A, B, and C.
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.
How many types of the Influenza Viruses are there?
According to the United States Center for Disease Control and Prevention, there are 4 types of Influenza viruses, but only three infect humans (A, B & C). Influenza D infects cattle and is not known to infect people.

What is the causative organism of seasonal influenza?
The common cold is an upper respiratory tract infection of viral origin, usually caused by a rhinovirus (up to 40% of colds), or by Coronaviruses (about 20%). These are the more common viruses, but there are more than 200 different viruses (some say as many as 700) that can cause the common cold. There are a huge number of different viruses from a number of different viral 'families' that cause cold symptoms. This is the main reason there is no vaccine for the common cold - there are simply too many different viruses to develop vaccines specific to each virus, and before a vaccine can be developed for a new viral mutation, it can mutate again.
How many Influenza A subtypes can infect birds?
There are 15 different Influenza A subtypes that can infect birds
What is influenza type A?
influenza type A is the most common and dangerous of all the types of this virus. it has caused many medical panics in history.
