In this article we will discuss about the structure of influenza viruses (explained with diagram). Particles of influenza virus are highly pleomorphic, mostly spherical having 80-120 nm diameter. But it also occurs in other form like long filamentous particles (2,000 nm long, and 80-120 nm diameter). They have helical symmetry also. The outer surface of […]
In this article we will discuss about the replication of influenza viruses. Influenza virus is transmitted from infected mammals through the air by sneezing. Sneezing creates aerosols which consist of several virus particles. Besides, influenza is also transmitted by saliva, nasal secretions, blood and faeces. Moreover, it also spreads through droppings of infected birds. These […]
