Influenza Spread through Surfaces
The transmission of influenza viruses can occur through various means. Although rare, some individuals can acquire the flu by coming into contact with contaminated surfaces or objects. Subsequently, if they touch their mouth, nose, or eyes, the virus can enter their body. Scientific studies conducted on influenza viruses have demonstrated that the virus can survive on non-porous materials, such as metal, for a minimum of 24 hours. Furthermore, if the virus is present in mucus on a surface, it can remain infectious for up to 17 days.
How Influenza Spreads from Person to Person
Influenza, commonly known as the flu, is highly contagious and spreads easily from one person to another. The primary mode of transmission is through direct person-to-person contact.
When an individual infected with the flu speaks, coughs, or sneezes, they release more than half a million virus particles into the surrounding air. These droplets can potentially land in the mouth, nose, or eyes of another person who is in close proximity, leading to infection.
It is important to note that the transmission rates of the influenza virus are highest when individuals are within six feet of an infected person. This proximity increases the likelihood of coming into contact with the virus-laden droplets and becoming infected.
