Can I Get the Flu Again After Just Having It
"Many people are non aware that the flu is much more serious than a common cold," says Dr Téa Eastward. Collins, Medical Advisor to the Earth Medical Clan on global health problems and member of the Influenza Hub editorial board.
"If you lot're an older person, in particular, the influenza could bear upon you desperately – merely it can be prevented. Nosotros're in the 21st century at present, and we no longer have the flu pandemics that took so many lives in the 19th and 20th centuries. Withal, people still get the flu because they don't know how to prevent it."
Practise the simple hygiene habits that will help you to protect yourself from the flu – specially during the influenza season.
Preventing is key
Before we look at some unproblematic steps you can take to help prevent yourself from catching the flu, let'southward explore why prevention is so important, especially when we're non equally young as we used to be. After all, the flu isn't something nosotros just take hold of in one case in our lifetime – or even in one case a yr.
Nosotros need to accept steps to protect ourselves every influenza season, throughout the season, as Dr Collins explains: "We get the flu multiple times – not simply every yr but throughout the year. At that place are different strains of the virus, and we never know how each strain will mutate and what will be circulating each season."
The flu changes constantly
Permit'south take a closer look at what Dr Collins means when she says there are multiple strains of the influenza and that these strains mutate
There are iii types of flu viruses: types A, B, and C (one). Type A viruses are divided into 2 different subtypes (2) and and then the A subtypes and B viruses are divided into different strains. Blazon A and B influenza viruses cause outbreaks and epidemics in humans (2).
There'due south a mix of different flu virus strains circulating amid humans (iii). These different strains tin can each spontaneously mutate, which means at that place's a gradual alter in the flu viruses circulating over the course of the flu season and from one season to the next (3).
These changes fool our immune arrangement (4). Think how nosotros explained in an before post that our immune system remembers a flu virus that has previously attacked it and can reply immediately? When a mutated flu virus tries to infect the states, our defense system doesn't recognise it and so tin't answer with such haste.
You may be more than at run a risk
Then, we've seen how and why unlike strains of the flu virus exist at whatever in one case, and that these unlike strains are continually changing. The severity of the influenza differs between strains and depends not only on the virus itself merely besides on a host of other factors – including the infected person (3).
While severe flu and complications can potentially occur in anyone, hospitalisations are more common if you lot are of pensionable historic period (3). You have a greater risk of developing astringent complications, such as pneumonia, since your immune response may also be less effective – especially if y'all have an underlying disease that reduces your resistance to infection.
Preventing the flu
Dr Collins reveals some simple steps you can have to help you avert catching the different strains of the e'er-changing flu virus: "We need to prevent the flu because treating the flu is practically impossible," she explains. "Prevention includes common hygiene practices and vaccine schedules; unproblematic things similar hand washing, covering our mouths and cleaning the door knobs – and making certain y'all go and seek assistance if you have a fever that persists."
If you lot are of pensionable, the flu could affect you badly. Information technology'due south much more than than just a cold. Practice the simple hygiene habits that will aid you to protect yourself from the flu – specially during the flu season.
