Pandemic and bird flu viruses are more deadly than seasonal flu. Scientists may have finally discovered why.
In the event of pandemic flu, poor countries will suffer the most.

It's not a matter of if, but when, the next deadly pandemic will strike. Will the world be ready?
Winter bugs are impossible to escape.
Illness often strikes when you’re stressed at work, not sleeping properly, or you’ve been out partying a little too much. Here's why.
Symptoms of the flu generally develop more quickly and are more severe than the common cold.
Most adults get two to three colds per year, while the flu is less common but more severe. Here's how to stop spreading them to others.
The Nipah virus in India is just one example of a viral outbreak in 2018.
It doesn't just seem like the world is experiencing more viral infections than before – it's a reality. And the way humans live today helps viruses thrive.
Cleaning counters and keyboards can remove flu virus, which can survive well there, a study suggests.
Vaccination against the flu is the best way to stop its spread, but a recent study suggests increasing air circulation and cleaning surfaces to remove the virus from the environment.
Getting rid of this scourge is nothing to be sneezed at.
There is no live virus in a flu vaccine. So you can’t catch the flu.
Pregnant women should get the flu shot to protect themselves, and their child for the first 6 months of life.
The protection of the flu vaccine is minimal, and may not be worth it.
Research shows for every 100 healthy adults vaccinated against influenza, 99 get no benefit.

Recent discoveries of ancient viruses are helping scientists understand their origins.
Despite the numerous campaigns promoting the flu vaccine to Australian health workers, uptake has been documented to range from only 16-60%.
The most effective way to improve flu vaccination rates among health workers in high-risk clinical areas and aged care facilities is to make it mandatory.
The flu shot is free for at-risk groups, and available to others for around $10-$25.
While not perfect, the seasonal flu vaccine is the best way to protect against influenza. There are a few changes to the flu vaccine and what is available this year. Here's what you need to know.
Giving pregnant mothers the flu vaccine protected their babies from getting the flu in the first six months of life.
Young children catch and spread the flu more than any other age group.
The flu vaccine isn't perfect but it's the best way to protect against these potentially harmful viruses. Most children aged six months to five years are eligible for a free vaccine in 2018.
People and animals live side by side – and can have pathogens in common.
No one then knew a virus caused the 1918 flu pandemic, much less that animals can be a reservoir for human illnesses. Now virus ecology research and surveillance are key for public health efforts.

The 1918 flu pandemic has long puzzled those who study disease outbreaks. Why was it so severe? While that question is hard to answer, one thing is certain: Vaccines would have lessened the toll.
It can be difficult to find records from epidemics long past.

One hundred years after a strange and devastating pandemic, researchers comb for clues in dusty libraries, church records and long- forgotten books.

With many men 'missing' from the population in the aftermath of the 1918 flu, women stepped into public roles that hadn't previously been open to them.
Face masks are a common sight in Asia. Why?
Whether or not masks can protect against invading or escaping bugs depends on the type of mask and material.
