It's that time of year again.Lots of people got sick nowadays and having that common illness called'the flu'.
Then what it is that we need all to know about?
Influenza, or "the flu" is a serious,contagious respiratory,or breathing illness.It's caused by a virus and spreads through tiny droplets in the air after someone who has the flu coughs or sneezes.So how we know if someone has the flu of just have a bad cold?
Generally, someone with the flu suddenly:
has a fever
has mucles and joint pain
has a sore throat and a bad cough
has a runny or stuffy nose
has a very fatigued with barely enough energy to move
Flu,symptoms usually appear one to three days after you've been infected,and you remain contagious to other people for three to four days after your symptoms start.That's why flu travels through a whole community in a sudden.
Most people get better within a week,but the flu can cause some pretty serious complications like pneumonia.That's especially true for the little kids,elderly and anyone who already has breathing problems like asthma.
Antibiotics that kill bacteria can't kill a virus,so doctors don't prescribe them to treat the flu.But there are new anti-flu medicines that can help them reduce the seriousness and length of the illness.They have to be taken early when the symptoms first start.Other than that,the only thing you can do to treat the fever,headaches and muscle pains of the flu is to drink plenty of liquids,take pain relievers and rest.
Isn't there any way people can protect themselves from getting a flu?
Well,it helps to remind others to cover their mouths when they cough or sneeze,and wash your hands often.But the most effective protection is to get a vaccination or "flu shot".
Since there are different flu viruses,scientists have to create a vaccine to work on the virus currently circulating.A yearly flu shot is recommended.It provides (70-90%) protection against infection for about a year.But even if you do get the flu anyway,your chances of getting serious complications are greatly reduced.
A flu outbreak in 1918-1919 was worldwide.One fifth of the worl's population was infected and 20-40 million people died.On 1997,people worry about "Bird Flu" that mostly virus found on birds and also lots of people died.
And as years goes by ,lots of other kinds of flu spreads worldwide that cause pandemic.Nowadays,we all face this kind of problem cause by another virus "Covid19" and became a pandemic.
So better take care of ourselves,cover when cough and sneeze.Wear protection gears and personal hygiene and healthy guidelines should consider.
