Is flu a pathogen?
Flu is caused by a pathogen (by viruses) but is not the pathogen itself, flu is the disease the pathogen causes. Flu is short for influenza which is an infectious disease of the respiratory system caused by influenza viruses.
Are colds and the flu from the same virus?
No, they are different viruses and different types of viruses. Most common colds are caused by either the rhinoviruses or coronaviruses (but there are over 200 kinds of viruses that cause the common cold). Influenza is also caused by too many influenza viruses to name them all, but they are in the taxonomic family of viruses called orthomyxoviridae. Human influenza refers to one of the three major types of flu viruses ( Influenza types A,B, and C) that are endemic to the human population. If you mean the "stomach flu" (which is more appropriately called viral gastroenteritis), then it, too, is caused by different viruses; most common is norovirus (aka Norwalk Flu).
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.
What type of virus cause flu?
Influenza viruses, Types A, B, and C. The flu viruses are all in the viral family called Orthomyxoviridae.
What is the difference between Type B flu viruses and the Swine Flu?
