Why does flu outbreak in winter?
The reasons are not fully understood, but low humidity, low temperature and more time spent indoors with other people could be causing it.
If I get the flu shot, can I be sure that I will not get the virus?
No
Although vaccination doesn’t always provide 100% protection, many studies have shown that it is much better to be vaccinated.
Annual flu shot is recommended for all children and adults. The flu shot is your best bet for a good winter season in Italy.
I had the flu last year, can I get sick again this year?
Yes.
Flu viruses are like chameleons. Every year they change and our immune system is not prepared for their new identity.
Sometimes they change just a little bit and we are quite effective in responding to the infection. Some other times they come with a totally new identity and the disease can be severe.
That’s why influenza vaccines must be formulated from scratch every year, in order to provide the best match with the circulating viruses.
The Global Influenza Surveillance and Response System of the World Health Organization takes good care of us by finding the best vaccine each year.
Can I get Flu from the vaccination?
No.
The vaccine contains already killed viruses or small parts of them that cannot cause the flu syndrome.
If after the administration you feel mild symptoms similar to flu (muscle ache, slight fever) that could be due to the normal, and quite common reaction to the vaccination.
If this lasts for more than a couple of days it is possible that you have been exposed to the virus shortly before the vaccination and the shot didn’t have the time to take full effect (usually this takes 2 weeks).
I think I have the flu. Do I need to go to the doctor?
The Flu shares symptoms with many other diseases. The most common are:
- fever
- cough
- body aches
- stuffy nose
- sore throat
- head ache
In the majority of people flu symptoms subside in a week, although weakness and malaise sometimes can last for many weeks.
Nonetheless flu may cause a serious infection. You should seek medical attention when symptoms do not improve or if you experience a worsening after an initial improvement.
A bacterial or a viral pneumonia are not frequent but serious potential complications that need to be treated promptly.
My doctor prescribed me antibiotics for flu, is it correct?
Antibiotics are used against bacterial, not viral, infections. A “simple” flu is usually not treated with antibiotics.
However, sometimes the flu virus may alter your lung defense mechanisms and some bacteria can take advantage of this, resulting in what doctors call a bacterial “superinfection” (i.e. a bacterial infection over a viral infection).
In this case antibiotics need to be administered.
If I’m feeling sick, should I be vaccinated anyway?
You should avoid to have the flu shot if you have fever or mild to severe respiratory symptoms (cough, runny nose, etc.).
After this episode, when you are feeling better and fever and symptoms subside, you can get a flu shot.
If you already had flu, the vaccine will just reinforce the immune memory of that and will boost the response to the vaccine, reducing the likelihood of a new infection during this season.
