Influenza commonly referred to as the flu, is a viral infection that attacks the respiratory system – that is, your lungs, throat, and nose. In most cases, people with flu naturally recover. Sometimes, however, influenza comes with deadly complications. Let’s review everything you should know about the flu and the Houston flu treatments available for this infection.

What Is the Flu?

The flu is an extremely contagious viral infection that usually attacks the respiratory tract, sometimes causing severe diseases and life-devastating complications like pneumonia. The flu typically spreads by contact with fluids from sneezes and coughs that are contaminated by the flu virus.

The flu affects people of all ages, from healthy people to the vulnerable ones, like children, pregnant women, and the elderly. It also poses serious risks to people with chronic medical conditions or a weakened immune system. Additionally, it can worsen some existing medical conditions resulting in hospitalization or even death. Below are some of the people at a greater risk of severe flu complications:

  • Children below 5 years
  • People with existing medical conditions
  • Aboriginal and Torres Strait Islander people
  • People over 65 years
