The world is battling a 'very tough' flu season this year. Already there was super flu, the mutated clade K, and now reports of <a href="https://www.healthandme.com/health-news/scottish-comedian-billy-connolly-has-been-incredibly-brave-in-his-battle-with-parkinsons-disease-says-actor-martin-compston-article-153298903" data-type="tilCustomLink">three children </a> from Ottawa and Eastern Ontario dying due to flu-related complications in the past two weeks have come up. This is the result of influenza A. This strain is currently circulating widely and affecting children more severely than ever. 

<h2>What Is So Unique About Influenza A?</h2>

As per the National Institutes of Health, US, influenza viruses that contains single-stranded RNA that are classified into three types: A, B, and C. Type A and B cause annual epidemics and even pandemics, while type C is a less common disease.

As per the Centers for Disease Control and Prevention (CDC), Influenza A viruses are descendants of the 2009 H1N1 pandemic virus that emerged in the spring of 2009 and caused a flu pandemic. These viruses, scientifically called the "A(H1N1)pdm09 virus," and more generally called "2009 H1N1," have continued to circulate seasonally since 2009 and have undergone genetic and antigenic changes.

Influenza A(H3N2) viruses also change genetically and antigenically. Influenza A(H3N2) viruses have formed many separate, genetically different clades in recent years that continue to co-circulate.

It is a fast-spreading respiratory virus responsible for seasonal flu outbreaks and, at times, global pandemics. It changes quickly through genetic shifts, which makes new strains harder to predict and control. The virus is grouped based on surface proteins called hemagglutinin and neuraminidase, with H1N1 and H3N2 among the most common strains in circulation. It spreads mainly through coughs, sneezes, or close contact and often comes on suddenly, causing fever, cough, body pain, and extreme tiredness. In some cases, it can lead to serious complications, especially in vulnerable groups.

<h2>Is There A Difference Between H1N1 and H3N2 Virus?</h2>

Both are a type of influenza A virus that causes seasonal flu. However, while <a href="https://www.healthandme.com/health-news/unique-symptoms-of-h3n2-flu-strain-in-uk-and-how-long-infection-now-last-article-153260152" data-type="tilCustomLink">H3N2 </a> changes its form regularly, which makes it harder for our immune system to fight it off, H1N1 is also known as swine flu. It is now a regular seasonal flu virus that comes back every year.

The recovery time of any influenza could last up to 5 to 14 days, the key is to monitor breathing patterns and avoid over medication. 

<h2>What Is The Best Line Of Defense?</h2>

This year, the flu is hitting hard everywhere. While winter flu cases are not uncommon, the virus is changing every day, which causes it to be more severe than ever. The best line of defense in this case is vaccination. Experts have suggested that despite mutation, vaccine provides the best defense. 

“The flu vaccine may not always prevent infection, but it significantly reduces the risk of severe illness, hospitalization, and complications,” officials said. They added that the vaccine takes about two weeks to become fully effective, making early vaccination crucial ahead of the holiday season, when virus spread typically increases.
