Influenza is a viral infection that attacks our respiratory system ie.our nose, throat and lungs.
At first, the flu may seem like a common cold with a runny nose, sneezing and sore throat. But colds usually develop slowly, whereas the flu tends to come on suddenly.
Common signs and symptoms of the flu include:
Influenza viruses travel through the air in droplets when someone with the infection coughs, sneezes or talks. One can inhale the droplets directly, or one can pick up the germs from an object such as a telephone or computer keyboard and then transfer them to their eyes, nose or mouth.
People with the virus are likely contagious from about a day before symptoms appear until about five days after they start. Children and people with weakened immune systems may be contagious for a slightly longer time.
Influenza viruses are constantly changing, with new strains appearing regularly. If one have had influenza in the past, their body has already made antibodies to fight that specific strain of the virus. If future influenza viruses are similar to those one have encountered before, either by having the disease or by getting vaccinated, those antibodies may prevent infection or lessen its severity. But antibody levels may decline over time.
Also, antibodies against influenza viruses one have encountered in the past may not protect from new influenza strains that can be very different viruses from what one had before.
Factors that may increase our risk of developing the flu or its complications include:
Pneumonia is one of the most serious complications. For older adults and people with a chronic illness, pneumonia can be deadly.
