PATHOLOGY

Detailed explanation-1: -People with flu can spread it to others. Most experts think that flu viruses spread mainly by droplets made when people with flu cough, sneeze, or talk. These droplets can land in the mouths or noses of people who are nearby (usually within about 6 feet away) or possibly be inhaled into the lungs.

Detailed explanation-2: -The flu is caused by an influenza virus. Most people get the flu when they breathe in tiny airborne droplets from the coughs or sneezes of someone who has the flu. You can also catch the flu if you touch something with the virus on it, and then touch your mouth, nose, or eyes. People often confuse colds and flu.

Detailed explanation-3: -When fighting an influenza infection, the body may raise its temperature to make it difficult for the virus to replicate. This abnormal increase in body temperature is known as a fever. A fever is part of the immune system’s response to an infection and is a typical flu symptom.

Detailed explanation-4: -The Attack Once the flu virus enters your body, it heads straight for the respiratory tract, often ending up in the lungs. The virus clings to the cells and drops its genetic footprint into the cell’s nucleus, where it copies itself and eventually takes over the functions of the cell.

Detailed explanation-5: -It is possible to get the flu twice during the same flu season. Since there are two types of flu strains – influenza A and influenza B – if you get influenza A, you can also get influenza B.
