Conceptual image of influenza viruses (red) in the airways. The virus particles are not at the same scale as the lung cilia (brown). Each virus consists of a core of RNA (ribonucleic acid) genetic material surrounded by a protein coat (red). Embedded in the coat are surface proteins (spikes). There are two types of surface protein, haemagglutinin (blue) and neuraminidase (light purple), and each exists in several subtypes. Both surface proteins are associated with the pathogenicity of a virus. Haemagglutinin binds to host cells, allowing the virus to enter them and replicate. Flu viruses.

Pneumonia caused by flu, computer illustration. Pneumonia is one of the common complications of a flu infection. Flu viruses in trachea, computer illustration. Influenza viruses have tropism to tracheal epithelium, they decrease tracheal mucociliary velocity thus contributing to the development of secondary infections of the lower respiratory tract. Due to this, pneumonia is one of the more common complications of flu infection.
