Influenza, commonly known as the flu, is a contagious viral illness that affects both humans and animals, primarily during the winter months. Influenza is highly contagious and can spread quickly from person to person through contact with respiratory secretions, such as droplets in the air and on surfaces when an infected person coughs or sneezes.
When a person with the flu coughs, sneezes, or talks, tiny droplets containing the virus travel through the air and can be inhaled by anyone in the vicinity. These droplets can also settle on nearby surfaces, such as counters, doorknobs, and other objects. When a healthy person touches these objects and then touches their mouth, nose, or eyes, the virus can enter their body and cause an infection.
In addition, the influenza virus can survive in the air for several hours and on surfaces for up to 24 hours. This means that if someone touches an infected surface and then touches their nose, mouth, or eyes, they can become infected with the virus. For this reason, it is important to practice good hygiene, such as frequent handwashing, to help prevent the spread of influenza.
Finally, influenza can also be spread through the air, such as in poorly ventilated rooms or crowded areas with poor air circulation. In this case, the virus can remain suspended in the air for longer periods of time, increasing the chances of infection.
In conclusion, influenza can be spread through contact with respiratory secretions, such as droplets in the air and on surfaces, as well as through the air in poorly ventilated rooms or crowded areas. It is important to practice good hygiene, such as frequent handwashing, to help prevent the spread of influenza.
