what is flu and its symptoms? How to treat them?
Seasonal influenza, commonly called “the flu,” is caused by influenza viruses, which infect the respiratory tract . Unlike many other viral respiratory infections, such as the common cold, the flu can cause severe illness.
Flu symptoms include:
100oF or higher fever
cough and/or sore throat
runny or stuffy nose
The flu can spread easily and unless your flu shot is up-to-date, you are vulnerable to catching the virus.The influenza virus can spread through the air and when infected droplets are inhaled, the virus can quickly multiply in the body. If there aren’t enough antibodies to fight it, flu symptoms will begin to manifest.
