Overview. 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. For most people, the flu resolves on its own.
Herein, how serious is influenza A?
In some people, the flu can be severe and lead to serious complications such as pneumonia. This is mostly likely to affect the very young, the elderly, pregnant women, Aboriginal and Torres Strait Islander people, and people with chronic health problems.
Influenza comes ultimately from the Latin word influentia, meaning “influence of the stars.” Today, however, the stars are no longer blamed for the flu. Inhaling influenza viruses causes the spread of the illness.
Consequently, what does influenza look like?
Influenza virus has a rounded shape (although it can be elongated or irregularly shaped) and has a layer of spikes on the outside. There are two different kinds of spikes, each made of a different protein – one is the hemagglutinin (HA) protein and the other is the neuraminidase (NA) protein.
